Disappears access to the Internet via WiFi. What to do if there is no connection to the Internet - correct the problems

The Internet is an integral part of our life. Lack of network is a serious problem for the user. There is no time to get through to the provider, but fortunately, it is possible to eliminate malfunctions. Below you read about the common causes of Internet problems and about how to eliminate them.

Possible causes of lack of Internet on windows 7

There are several reasons for the absence of the Internet. Some of them relate to the computer drivers and its equipment, others affect system errors and the absence of the correct network settings.

The most common causes of the absence of the Internet are:

• mechanical damage to cable or ports;
• lack of a network card or its drivers;
• incorrect configuration of the connection on a computer or router;
• the presence of viral software.

The Internet may also be absent due to debt on the personal account or due to the accident accident. Before trying to eliminate malfunctions, check if they are not caused by these factors.

How to check the status of the network

Among the problems with the Internet, you can select those that are found most often and periodically arise from most users. Allow them is very simple. The first thing to do is check the status of the network.

You can do this in two ways:

In both cases, its state will be described under the icon of your network.

Unidentified Network without Internet access

If the computer "sees" the network and connects to it, but does not receive Internet access, the network status will be called this: "Unidentified Network. Without access to the Internet. " What to do in this case?

The computer "sees" the network and connects to it, but does not receive Internet access

Reloading router

If you have a router, the first thing to do is restart it. He may simply do not have time to update the data, and because of this, access to the network will disappear. The reboot is performed in the following order:

1. First, the router is disconnected from the network. It is important to pull out the cord from the outlet, and not to restart using the button on the equipment - you need to stop the flow of electricity for a while.
2. Then for 10-15 seconds, the router must be left disabled.
3. After that, the router is connected back to the network and wait until the indicators light on it.

After the indication on the router appeared, you can check whether access to the Internet has appeared. Usually after rebooting the Internet appears within 7-10 seconds.

Checking network settings

Network settings are the data that allows the computer to connect to the distributed network provider. These settings produce a company that provides access to the Internet (usually registered in the contract for the provision of services). Sometimes the settings on the computer are knocked up, and because of this, the device cannot connect to the Internet.

In order to check the network settings, you need to open the Protocol properties. You can do it like this:

1. Go to the "Control Panel" through the "Start" menu.
   The "Control Panel" is located in the start menu "Start"
2. Select "Network and Internet".
   In order to find the desired section, you should select the "Category" viewer parameter in the upper right corner of the screen.
3. Open the "Network and Shared Access Center" section.
   In the "Network Management Center" you can check the connection status, create a new network, carry out almost any actions with your internet connection.
4. Find the "Changing Adapter Settings" section.
   Find the section "Changing the Adapter Settings"
5. In the list of networks, select the desired one, click on it with right mouse button and find the item "Properties". Open "Properties" can only administrator.
   The network you need will be called "Local Connection" or "Ethernet"
6. In the list, find the "Internet version 4" item, highlight it with a single click of the left mouse button. After that, the "Properties" button is activated under the list, you need to click on it.
   The selection of the item is made by a single click of the left mouse button. Take a tick next to the item not needed

When the window is open, you need to still understand which settings must be entered. There are three options:

We understand what is an IPoe and PPPoe protocols, but we will not go into terminology. It suffices to understand which protocol is used on your link. To do this, just look at the network settings issued by the Provider (specified in the contract).

Settings may be the following:

• password and login are used on PPPoE protocol,
• IP address, subnet mask, gateway and DNS are used on the IPOE.

If you are using PPPoE and you are connected directly, that is, you do not use the router, after checking the settings through the Properties of the Protocol you need to re-create the network.

1. Return to the "Network and Common Access Control Center".
   This configures only PPPoE connection. Protocol properties are used to configure the wired IPOE
2. Open the "Creating and Configuring New Connection" item.
   Point switching is performed by a single mouse button.
3. Select "Create and configure a new network" and click "Next".
   The selected item will be highlighted with a bright blue background.
4. Click on the "high-speed" version.
   Waiting for the search for available connections may take a few minutes.
5. When an error occurs, select "Create a connection anyway".
   This error appears quite often, but the connection still can be created
6. Next, you will need to enter network settings, as well as the network name - is the name of the connection. You can use the name of the company-provider or other.
   The connection name is its name, and the username and password are network settings. It is worth noting that the password has nothing to do with the wi-fi key.

After that, the network will be updated, and you will need to check the availability of network access.

Reset TCP / IP Settings

Sometimes the cause of problems can be internal system errors. TCP / IP - a set of network protocols responsible for data transmission. You can reset it as follows:

Check drivers

The reason for the lack of access can be outdated drivers (usually such a problem is related to the recent update of the operating system). Check their condition.

In addition, by right-clicking on the driver name, you can select "Delete" item, and then restart the computer. Then, when turned on, the system will automatically install a missing driver.

After removing the drivers and reboot the computer, the system will automatically install suitable drivers

If an exclamation mark is worth next to the driver icon, you will need to fully reinstall drivers and check the performance installed in the computer network card.

The default gateway is not available

Detect the next problem will help the network diagnosis. Right-click on the icon of your connection, select "Troubleshooting".

Pressing the right-click icon, you can open the "Network Management Center"

If after system diagnostics there is a message about the unavailability of the gateway, the following actions can help.

Ban on disconnecting a network adapter for energy saving

Sometimes the system disables the power adapter - the device that allows you to connect to the Internet - to save energy. Try to damage this option.

1. Find "Device Manager" through the search string in the Start menu.
   The opening of the "Device Manager" through the search is not the only way, but the most convenient
2. Expand the "Network Adapters" tab, select the desired, click on it with the right mouse button.
   In the context menu, click on the item "Properties"
3. Select the item "Properties" and open the Power Management tab.
   Changing these settings will help solve and break off the Internet after the computer transition to sleep mode
4. Remove the mark next to the "Allow shutdown of this device to save energy" and save the data.
   After changing the settings, do not forget to save them by clicking on the "OK" button

Update or reinstall drivers

Also through the Device Manager, you can update the drivers: Expand the "Network Adapters" tab, right-click on the network driver and select "Update" or "Delete", then restart the computer.

If the action does not help, you can download drivers from the sites of their manufacturers and install yourself. Typically, manufacturers offer download .exe driver drivers, so you will only need to start the downloaded file and accept the agreement.

When connecting to the Internet, an error 651 occurs through the router

This error occurs when you try to connect via PPPoE protocol. Rarely, but it happens that users create a new high-speed connection while the provider uses the IPOE protocol. Therefore, you first make sure that you are using the PPPoE protocol.

After that, you will need to re-create the connection. The process is described in detail in the "Check Network Settings" section (all you need to do, through the "Network Management Center" Create a new connection). If it does not help, read further.

Disable antivirus

Sometimes antivirus programs block access to the Internet. Often the solution to the problem can be disconnected antivirus. Click on its icon in the Right-click Control Panel and select "Disable". Sometimes antiviruses block access to the network even in the "sleeping" state, so you can try not only to disable, but also completely delete this software. If this action helped, inform the situation in the technical support of antivirus.

Problems on the router

The cause of problems can be several problems associated with the router:

• incorrectly connected cable;
• invalidly entered settings.

First try to do the following:

1. Disconnect the router from the network.
2. Without connecting the router, pull out the network cable from it and connect back to the WAN / Internet port, making sure that when connecting the plastic clips on the plug closed.
3. If the cable goes to the computer from the router, disconnect it from the LAN connector on the router itself and from the network card connector on the computer, then connect back.
4. Connect the router to the network.

If access does not appear, check the network settings entered on the router. In order to go to the router, it will be necessary in any browser (in the address bar) to introduce "192.168.1.1" or "192.168.0.1". Sometimes the address for which you can go to the router is different, so if the input is not made through the specified addresses, check the data in the instructions.

Files from the Internet are not downloaded

It can also happen that access to the Internet is active, and the files are not loaded. This problem is usually associated not actually with the Internet, but with a computer, software.

What you can try to do:

• try to download the file from another source - perhaps you can not download anything simply because the resource does not support downloading;
• try downloading through other browsers;
• check the computer for malicious software using any official antivirus.

Multimedia does not work on the Internet

It happens that the Internet is working, and video or audio materials are not played. What to do in this case? First check whether the files loaded to the computer are played. Perhaps the cause of problems lies directly in the audio settings of the computer. If the files are reproduced from the computer, but from the Internet - no, read further.

The first thing to be done is to understand why such a problem arises. It can be in the browser error, the absence of plugins. To establish a computer work, do the following:

Diagnostics PPPOE

Additionally, in order to find out the causes of errors when using PPPoE, you can use the "troubleshooting center". Then the system will independently check the presence of errors and offer possible solutions.

PPPoE (Point-to-Point Protocol Over Ethernet) is a communication protocol through an Ethernet network that works on the "point to point" principle and gives the user a number of features: encryption, authentication and data compression. It is necessary for the user authorization system, which allows you to facilitate tracking the time of providing and paying network services.

Press the right mouse button on the network connection icon and click the Diagnostics button. After that, the analysis will be made, Windows will try to cope with difficulties on their own, after which it will offer you to perform several actions.

Error 619.

Restart the computer and disconnect all security systems: antiviruses and Windows Firewall. The latter is turned off in the following way:

Error 633.

There is only one solution option:

1. Restart the computer.
2. Try connecting again to the Internet.
3. Create a new connection.

Error 638.

The main causes of the occurrence:

• damage to the network cable;
• disruption of drivers or network fees;
• invalid connection setup;
• malfunctions on network equipment (router);
• the presence of viruses on the computer.

First of all, make two things: check the integrity of the cable and the presence of an indication on the router. Never neglect these actions when issues with the Internet so as not to lose time on trying to solve the problem caused by mechanical damage.

It is clear that if the cable is damaged, you need to call the provider. But if there is no indication on the router (which indicates that the device is de-energized), before it is replaced, try to reconnect the router into another outlet.

After checking the performance of the router and the cable destination, check the computer for the presence of viruses by any antivirus program.

If the above does not help, restore the connection to the network - check the correctness of the entered settings both on the router through the settings and on the computer itself through the Protocol properties. Both actions are described in detail in previous paragraphs.

Error 691.

The only reason for the error is 691 - incorrectly entered password and login (network settings). Therefore, the first thing you need to do is re-create the connection. The process has already been described earlier - you need to go to the "Network Management Center", select the "Create a New Connection" item and then enter the correct network settings. After that restart the computer and check the Internet connection.

If the action does not help, inform the failover of the provider. Perhaps an accident occurred on the line, which caused a mistake.

Error 720.

The easiest way to solve this problem is to reinstall the operating system. To do this, it is enough to download the operating system file from the Windows site to the disk (or purchase a disc in the store) and run on the computer.

You can also try to update the TCP / IP protocol. The action is described above, but you can also conduct a deeper operation, fully reinstalling the stack. Re-install the stack yourself is dangerous - it will have to work with system files, and their damage will affect the operation of the computer. Therefore, try simply updating the stack, and if the action does not help, contact a provider or professional master.

Network cable is not connected

If a message appears when checking the connection status, the network cable is not connected, the first thing is to really verify the correctness of its connection and the absence of damage. If possible, try using another network cable.

Make sure the cable is connected correctly. On the router, the network cable must be connected to the WAN or Internet port, and the cable leading from the router to the computer must be connected to the LAN connector. On the computer usually there is only one port, so it will be difficult to make a mistake.

The WAN or Internet port is used to connect to a power cable router, and the LAN ports are used for cables to computers.

Next, check the state of the router (if any). Its indicators should burn as usual. If there is no indication, reconnect the router to another outlet, try resetting the settings on the router (button "Reset" or "RESET") and re-enter them again. Unscrew the settings should only if you are confident that you can independently configure the router.

Also check the status of the network adapter drivers and try to update them.

Additional safety settings check

Many of these problems may also have security installations. This applies to the case when the PPPOE protocol is used. Therefore, if the proposed operations do not help to solve your case, try checking the security security settings.

1. Open the "Network Connections" section.
2. Right-click on your connection.
3. Open the Security section and install the use of the "unsafe password" in the list that opens.

These are the main ways to diagnose the connection on Windows 7 and troubleshooting. Do not forget that the cause of the absence of the Internet can be a banal arrears or an accident on the line. If the methods described above did not help you, contact the provider in order for technical workers to diagnose and solve the problem for our part.

If you encountered designation Network "Without Internet access" means that your network does not receive packages from outside. The question appears, and what to do and how to eliminate this problem? The universal solution does not exist, you will have to try each of the presented methods before finding out the cause and elimination of an unidentified network.

Possible problems of the provider

The first step in such situations is to call a service provider to find out if there is access to the Internet. On the side of the provider, technical works may be conducted or an unexpected breakdown. In order not to climb in vain, find out the involvement of the supplier.

Call the company's call center, look at the official website or page on social networks. As a rule, they write about topical issues. If the information is missing, look at the comments of other users. Perhaps you are not alone collided with the fact that the computer does not connect to the network. I do not solve problems with the provider, so it remains only to expect.

Cable or connector problems

Next, inspect the LAN cable. Make sure that the plugs are good, while do not have physical damage. Inspect the wire isolation and check if there are no beggars. You can try to replace the lan cable connecting the router and computer. If direct connection is used, then exit the partition and to the site by checking the wire along the entire length. If damage is detected, naturally call online managers immediately. They must send the wizard to replace the network cable.

Routher malfunctions

The second most common source of message appearance "without network access" is a router. The list of frequent problems belongs:

• selection of incorrect connection type;
• setting the wrong IP address or login password (when using ADSL, L2PT or similar connections);
• there are any restrictions in the settings;
• hardware problem (a capacitor sank or burned the board).

In the latter case, you will need only help professionals or buying a new modem. All software flaws can be eliminated independently subject to the fulfillment of correct action.

When there is no Internet access on the computer, restart the router and PC. During the operation of devices, minor failures may occur, which are not critical. Reboot allows you to eliminate these problems. On the computer, it is enough to click a button that is responsible for this function or select the corresponding menu item in the Start section.

With the modem is all easier: press the POWER button to turn off, and then turn on the machine. If there is no such keys, just pull the power supply outlet.

Settings in the web interface

The installation of incorrect parameters in the modem leads to the creation of a network without access to the Internet. The solution is quite simple: go to the web interface and set the correct parameters. Next, we will tell you in detail about these steps.

How to enter the web interface?

Connect to the modem through the lan cable directly. To log in to the system menu, you need to find out the data for authorization (login, password and address to which the transition will be performed). Find this data on the label glued to the device case. Fields are called IP Address, UserName and Password. On some models, they are translated into Russian.

The entrance is performed a couple of steps:

1. Discover the browser on the PC (Google Chrome, Firefox, Opera or Standard). Write an IP address to the entrance and Clause Enter in the address bar.
2. On the Authorization page, fill in the fields (the first is the username, and the second password). Click "Login".

You must get to the start page of the router settings.

Internet connection settings check

Most routers allow you to use multiple types of connectivity. For each of them require their own parameters:

Problems on a PC or laptop

Try connecting the router to other devices, such as a laptop. Correct work and the lack of error "No Internet access" speaks about problems in a personal computer / laptop that is used to access the Internet.

Diagnosis of problems

Windows operating systems have standard troubleshooting tools. They are not always able to return access, but often cope with contacts to the local network. To start the procedure, follow the instructions:

If the faults are not detected, run additional items ("Home Group" and "Network Adapter"). The system will analyze other parameters and may find faults there.

Setting up IPv4.

Despite the global transition to IP version 6, the classic IPv4 is used together, so the incorrect address of addresses can lead to access errors. You can configure the protocol via the operating system interface:

Also addresses can be requested from the provider. When using a static connection, you often need to set parameters in the OS itself.

Reinstalling the network card driver

For the correct operation of "iron" in the system, a special driver (specialized software) is used. After installing Windows, through its database, try to find drivers to independently put them, but not always successfully. The versions of the disk complete are usually outdated, so we recommend updating the driver via the Internet.

The first and most reliable method is to download the desired software from the manufacturer's website. Find the "Drivers / Utilities" or "Support" section, select your network card model and OS version. After download the installer, and then simply start it on the computer.

Alternative, but less efficient option - update through standard operating system functions:

1. Right-click on the "My Computer" icon. Select the "Properties" string.
2. On the left side of the window, click on "Device Manager".
3. Find a network adapter. According to it, PCM and "update drivers".

You can also find specialized utilities created to search for topical versions of drivers on any "iron". Popular software is Driver Genius. The user is just enough to run scanning. The utility will find all the components that need update. The functionality allows you to update only the selected system elements. Soft comes in Russian.

Change MAC Address Network Card

Part of Internet providers uses connection with reference to the MAC address. This is a unique identifier that is assigned to any network equipment. At the hardware level, a regular user will not be able to change the mac address, since this requires programmers. However, you can change it at the program level, which is enough to connect to the network.

Change is performed according to the following instructions:

Please note that the MAC address consists of 12 digits in a 16-riche system. To check the correctness of the change in the console, enter the IPConfig / All command.

There is a second method of change through the registry. You need to go through the path of the network card, while changing the value in the NetWorkadress field for the corresponding component.

Check Firevol

The problem is why the Internet is not yet available, maybe in firewall. This is a built-in defender in Windows, which blocks unwanted connections. If there is an antivirus in the system, it can be safely disabled:

Cleaning the DNS cache and reset TCP / IP protocol settings

Errors may occur in files related to TCP or DNS stack. It is recommended to reset the cache for these components:

Enable FIPS Compatibility Mode

In some cases, OS Windows 7 or the newer will have to activate compatibility mode with federal FIPS standards:

• Go to the "Condition" point of the adapter. Click the Wireless Network Properties button.
• Next, go to "Advanced Parameters". Put the box next to "Enable Compatibility Mode ...".

If this feature is enabled, try to deactivate it.

If the cable goes to a PC directly (without a router)

With direct Internet connection, all methods are relevant to the computer with the exception of the router setting section due to the lack of the latter. We also recommend re-create a re-connection connection through the "Creating a new connection" item.

There is access to the Internet, but the error does not disappear

The reason for this situation is more often connecting through a proxy server. You need to get to the editor of local group policies. Click Through Starting "Run", and then enter the command specified in the image.

After that, activate the "Disable Active Sensing for the Network Connection" indicator. " In Windows 10, this parameter is called differently ("Disable active network connections performance checks"). At the same time, remember that with actual problems with access, information messages will not appear.

These are all current methods, how to get rid of an unidentified network. If you are new, while you do not have the experience of setting up the router or operating systems, we recommend contacting the specialist. Unprofessional intervention can only incur the situation.

Today we are all with you strongly dependent on the Internet. And when it does not work, panic starts immediately, the heart goes into the heels and life seems meaningless. Maybe you are funny, and for some it really is.

Especially the user is lost when the Internet is connected, but does not work. Today I will tell you why this happens and what to do if this happened to your network.

Why doesn't the Internet work?

If you are connected to the Internet, but it does not work, the first thing you need to find the cause of the problem. To do this, you must restart all devices that are associated with Internet access. This refers to the router, computer and so on. Most often, this reboot completely solves all the problems with the Internet, and it begins to work properly. If after rebooting the router and the computer, the expected result you did not get, go to the following "therapeutic" procedures.

Today, most often the Internet connects to the Wi-Fi router. If you also have, then you need to check whether the Internet access indicator is on or not on the router. For those users who use the TP-LINK router, the Internet access signal is marked with a globe icon. On other routers, this signal most often sign "Internet".

If the indicator is not lit, you need to check the settings of the router. If everything is normal with them, then call the technical support of your provider and ask why there is no Internet, it is possible to repair a highway or network.

But, if the indicator is on, then there is no connection and the provider is not to blame. Check out Internet access on other devices. It does not matter what it will be - phone, tablet or other laptop. So you can figure out what direction you dig further to solve this problem. I will say right away, the case when the router is connected to the Internet, knowingly well working, but it does not distribute it to other devices, is considered a very rare case. The reason for this problem lies in the router failures. Fix it is not difficult. You need to reset all settings up to standard and reconfigure it again, remember that after resetting all the settings and the Internet can not work until the router is configured correctly!

There are often cases when only one device or a computer can be connected to the Internet for the routeer tools, and everyone else can calmly go to eat. In this case, it is necessary to seek the cause directly on this device.

If you are connected to the mobile Internet via a USB modem or WiFi module connected to a USB port, then try to disconnect it and re-connected. If it does not help, try using another port for connecting. Perhaps a reinstalled driver will help you solve this problem.

Check Internet connection in Windows

In the case when the Internet is connected on your PC or laptop, but does not work, and at the same time you are 100% confident that the cause of this is the wrong settings, then you need to perform a number of procedures that will quickly solve your problem.

You need to start the reconfiguration from the plugging of any popular site. To do this, click the combination of "Win + R". So you call the "Run" window.

In the text input box, you need to enter the following "CMD" and click on "OK" .. If you are not a fan of my site, you can write Google. After that, click on Enter and wait for the result. If everything is fine, then the server will send you about this answer:

If in response from the server there will be a string "When checking the connection, it was not possible to detect the nodepec-komp.com. Check the name of the node and try again, "then you need to type another command, for example" Ping .8.8.8.8 ". This is the IP address of the public DNS server from Google, which will always be available. If the computer has access to the external network, then The answer will be the same as in the picture above, but with other numbers after the "answer from ...".

If the IP address Ping passes, but in the browser it does not open, then most often it says that there is a connection to the Internet, but the network does not work because of the wrong setup of the network card, namely - they are not registered or registered correctly DNS server. How to fix it, I will tell a little later.

If you are watching another response from the server, then you need to check access to the router. We will also check with ping. You can find the IP address of the router on the sticker, which is glued on the back of its housing. Most often, the IP address of the routers "192.168.1.1" or "192.168.0.1". On my router is registered the first address, so I got this is the answer:

If the router pins, and there is no Internet node, most likely the reason lies again in the router settings or in it itself.

But if the router for server requests is not available, that is, the reason to climb into the settings of the network adapter on the computer. But, before doing this, turn off the antivirus and firewall, if anyone is. Sometimes these two "comrades" are the reason for working with the Internet.

If, after that, the Internet did not earn, although the connection is also available, press the "Win + R" key combination again, but now in the "Open" field we register "NCPA.cpl.".

If you all prescribed correctly, the Windows network connections window will open. In it you need to find your active connection and click on it with the right mouse button, then select "Properties". In the window that will open up the line "IP version 4 (TCP / IPv4)" and click on it twice to open the protocol parameters .

We note "Get the IP address automatically" and "get the address of the DNS server automatically." Click Okay and check the result in the browser.

If it did not help, then I note the point "Use the following addresses". You need to register an IP address from your router subnet. If it has IP 192.168.0.1, then the computer install 192.168.0.2. If the router is used 192.168.1.1. The PC will be 192.168.1.2. Mask 255.255.255.0. As a gateway, you need to specify the address of the router. It can be registered as a preferred DNS server. Alternative DNS You can specify the server from Google - 8.8.8.8.

In any case, see my video to speed up the Internet, if you apply all the settings then the Internet will have to earn.

We increase the speed of the Internet to the maximum!

I hope at least one of the ways you will definitely help return access to the Internet. If none of the options for solving the problem did not help you, then you will have to call a specialist who will determine the true cause and solve this problem. But, I am sure that it will not reach this and you fix everything yourself.

Before you begin to find out why Wi-Fi or Internet does not work, you should know (especially for those who only purchased a Wi-Fi router), which is just enough to connect the provider cable to the router, it still needs to be configured (configure Internet and Wi-Fi network ). All the following methods are valid if you have worked Wi-Fi and the Internet before you, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is dedicated to the impossibility to connect to the wireless network, the second part will respond to your questions if you connected to the Wi-Fi network, and there is no Internet.

Cannot connect to Wi-Fi network.

Reloading the router.

The first thing you need to do when problems with connecting to a Wi-Fi network is to restart the router. To do this, simply disconnect the power supply from the router and later connect again. After 1-2 minutes. The device will boot, then try connecting again to the wireless network. To further avoid such situations, I recommend to update the router firmware (perhaps the manufacturer knows about the problem and corrected it in the new firmware).

Enabling Wi-Fi module on a laptop.

Check whether Wi-Fi is enabled on a laptop, I will not turn on, I described all Wi-Fi in the article How to enable wi-fi on a laptop .

Changing the wireless network mode.

If you are trying to connect the device (laptop, smartphone) to which more than 5-7 years, it is necessary to consider that it may not support the modern Wi-Fi mode - n.. Therefore, you need to switch the router to operation mode, which is supported by the device or enable mixed mode b / g / n. More information about Wi-Fi modes is described. In order to switch the wireless network mode, you need to go to the web interface of the router, go to Wi-Fi settings and select the appropriate mode.

Deleting the SSID refined network name.

One of the possible problems is not able to connect to Wi-Fi - it is a duplication of the Wi-Fi network (SSID). Suppose you came to your acquaintances, they have a Wi-Fi network called "home", you have successfully connected to it. Time passed and already from other acquaintances or at home you met the same network name. Laptop (this also applies to tablets, smartphones) Attempts to connect to the network using a saved earlier password, but it cannot succeed because a new password is used for this name. To solve this problem, it is necessary to remove the coinciding network from the list of saved Wi-Fi networks.

To do this, right-click on network icon In the lower right corner of the screen and select "Network and Shared Access Center".

After that you will see a list of saved wireless networks. If you see that the network to which you are trying to connect is in this list, you must delete it from this list. Select the network and click the Delete button. After that, to connect a wireless network, you will need to enter a password.

No Internet via Wi-Fi.

Checking the payment of the Internet.

The simplest thing that may be with a non-working Internet - it's time to pay for it or work from the provider. To find out the situation, call the provider and check if you have a debt for the Internet and are not working on the line.

Static IP address.

One of the problems not to work the Internet may be a prescribed static address not with the network settings that are necessary. In this case, I recommend using automatic receiving network settings. To do this, you need to get into the Network Management Center and Common Access. One way to do this is the right mouse button on network icon In the lower right corner of the screen and select "Network Management Center and Common Access".

Another method is to use hot keys + , Enter the command NCPA.cpl And press ENTER.

It does not matter how much way you used the result will be one - the network connections window will appear on the monitor. Next, you need to click on the wireless connection with two mouse clicks, in the state window that opens, select "Properties" in the Properties window "Internet version 4 (TCP / IPv4)"

Problem with router.

The Internet may not work because of the router failure, the simplest thing that can be done is to restart it. Situations occur when the router resets the Internet settings, then it is necessary to connect to it on a web interface and re-enter the Internet settings, to further experience less problems with the router, I recommend updating its firmware.

Conclusion

In this article I described all methods for solving problems with Wi-Fi and Internet. If the specified methods did not help you, you can describe in detail the problem in the comments and, along with the readers of this site, will try to help you.

The disappearance of the Internet connection is an urgent problem for any PC user. The reasons for this can be a lot of both hardware, such as a cable break and software, such as incorrect adjustment of the router.

Most of the problems with connecting to the global network can be solved on their own, and another part you need to be able to correctly diagnose so that when contacting technical support, to give specialists the most complete malfunctional information. To understand the subtleties of these processes this article will help you.

Signs of lack of compound

It is possible to determine that there is no connection to the Internet in the following features:

This is not a complete list of signs, but they are most informative. The presence of any item means that there is a problem with connecting to the Internet.

Determination of the cause

The first step in the fight against the restriction of access to the network is to search for the cause of the malfunction.

First of all, if you go online through a router set at home, it is necessary to check its performance, namely:

When using Wi-Fi, you must check the operation of your device's wireless network adapter by connecting to the access point of another computer or mobile phone. If a special utility from the provider is used to connect to the Internet, then it takes it to reinstall it.

In cases where there is no connection, there is no Internet, you will most likely have to contact the service provider's technical support service, since such a situation often occurs when cable breaks, faults of the provider's network equipment or a global network equipment blocking due to the delay of payment.

Use of standard tools

In Windows 7 and in the remaining OS OS, there are automatic correction of network problems. To access them, click the PCM on the network connection icon (the right lower outline of the display) and select "Diagnostics Connections". After that, the process of checking and correcting connection errors will start, and then the results report will be displayed.

If the previous procedure did not help and you still do not have the Internet, you should check the connections between the computer, the router and the provider cable, then restart the router and PC. Such a sequence of actions is also relevant if access to the network is carried out via a Wi-Fi router.

A more radical, but the publicly available method for restoring the working capacity of the router is to reset its settings using a special revealed button on the housing. It should be held for a few seconds, then the router will reboot to the factory settings and it will have to be configured to work with the network of your provider.

If you do not have access to information, how to perform this procedure, then when the router do not immediately apply to the technical support of the Internet provider.

Changing the method of connecting to the network

If the modem does not work, then you can try to connect a PC to the Internet directly. Requires an introductory cable to connect to a computer network card and change the method of obtaining the IP address on automatic, for this:

Manual connection configuration

If the procedure described above helps and the Internet appears, then the DHCP server is not enabled on your router and due to the PC there is no connection. Especially often such a problem occurs from new routers. It is possible to get around without configuring the settings of the modem itself. To do this, you need to manually register the IP address for the computer network card.

We prescribe an IP address - video instruction:

This is done in the same "properties" dialog of the network adapter parameters. Accessing this window is described in the previous section of the article. Only now you need to put markers opposite the "Use the following IP address" fields and "use the following DNS servers addresses". In the IP Address field, enter the value 192.168.1.2, in the string of the mask - 255.255.255.0, and in the gateway to write down - 192.168.1.1. As DNS servers, you can specify the publicly available Google addresses - 8.8.8.8, 8.8.4.4 or Yandex - 77.88.8.8.

Replacing IP Address Modem

The identification of the Internet will not occur due to the same intra-network IP addresses of the computer and the router, so you need to be able to change this parameter in the modem settings. On the common routers of the TP-LINK line, this operation is performed according to the following algorithm:

Change Mac Addresses

Mac Address is a unique identifier for any device on the Internet and when connecting to a network of two computers with the same Mac, one of them will be lost connection. Problems may arise both due to poppy PC network card and due to the router address.

The algorithm for changing this parameter in the router depends on its brand. So for the ASUS modem you need to go to configure through the browser, open the "Ipconfig" tab and click on the WAN & LAN section. Then it follows at the bottom of the open dialogue to find the MAC record and fix it. Then click on the "Apply" button and restart the device.

Editing Mac on a computer running Windows 8 and 7 is possible according to the following algorithm:

1. In the first two positions, the address should not be zeros.
2. At the end of the sequence, it is worth exposing 2, 6, A, B, E.

Video instructions for changing Mac Addresses on PC:

If these conditions are non-compliance, changes may not be applied.

Appeal to Technical Support

If, after all attempts to solve the problem, there is still no connection to your Internet, then you should contact the telephone in the technical support of the provider.

The necessary number is usually listed in the contract for the provision of communication services and consultations are carried out by all Internet traffic providers for free.

Practice of personal access to Tech support Beeline and Rostelecom shows that quite quickly and fairly competent specialists will answer the call, who will help to deal with cables, connecting, router and computer settings, will say if there are problems with the network on the linear part.

If, together with the operator, the problem will not be solved, and you are still without access to the Internet, then the call will be directed to narrow-neighboring engineers of the repair department.

Conclusion

Despite the fact that most of the problems can be solved on their own, the appeal to the technical support service will allow you to solve the question of what to do in the absence of the Internet, as soon as possible and will save many nerve cells that are so slowly restored. But if you like to engage in setting up and repairing network equipment personally, the recommendations from this article will help you in this matter.
