Why not turn on Wi-Fi on your phone? What to do if Wi-Fi does not turn on on Android

In the modern world, every person has a mobile phone, iPhone, Android or tablet. And we can no longer imagine our existence without them. And also without the existence of the Internet. Each device, whether it’s a tablet or a mobile phone, connects to the Internet or Wi-Fi. But this does not always happen successfully; there may be several reasons why the connection to the network will not occur, and both your device and the Internet source may be to blame.

Let's look at the possible reasons why Wi-Fi doesn't work on your phone:

1. The Settings on the mobile device may be incorrectly set, blocking data transfer from the router.
2. The Wi-Fi router may not be configured correctly due to which the mobile device cannot connect to the network.

Let's take a closer look at the first cause of the problem and its solution.

To connect your mobile device to Wi-Fi, you should:

• In the Settings of your mobile device, select Advanced. Next, Modem mode and mobile hotspot and click Portable Wi-fi hotspot.
• Select Configure Wi-Fi access point in your mobile device. Give it a Name, choose a security type and come up with a password. Then Save. And every subsequent time you want to visit the Internet, your mobile device will connect to it independently.

If you cannot connect to a wireless network, then you need to check the Wi-Fi signal strength. The signal needs to be strong enough for your phone to connect, so try changing your location to get a stronger signal.

The reason is that the mobile device does not connect to the wireless network. may be due to incorrectly set date and time on it. To fix this problem, you need to go to the Settings of your mobile device and set the correct Time and Date, taking into account the time zone in which you are located.

Another reason

Also, the lack of connection of the phone to Wi-Fi can result from changing the password; the owner of the mobile device may not know that the password has been changed in the network settings. And when connecting automatically, Wi-Fi access will not be displayed. To fix this problem, you need to find out the password and Internet access on your mobile device will be restored.

A malfunction in the software of a mobile device can also lead to disconnection from the Internet. To do this, you do not need to change the settings, just download the Wi-Fi fixer application, when installed, information about the current status of the mobile device will be displayed, you will need to delete all previous connections and reconnect to the signal you require and enter the password.

If the Settings in your mobile device are lost and you cannot connect to the Internet. Reset all current settings to factory defaults. You can do this procedure yourself, or contact specialists at a service center. If you decide to try resetting all settings on your device yourself. Then search the Internet for results for the query “reflash your model of mobile device.” If you start doing this procedure as for a mobile device of a different model. Then remember that you can only harm your tablet, android, etc., then it is better to trust the specialists.

Let's move on to the second reason and its elimination

First, reboot your router, which distributes the network distribution signal. Make sure that you have paid for the Internet and it is in working order. If you cannot connect to Wi-Fi, try connecting your mobile device directly to the router by connecting the cable. Also check if all the wires are properly connected to the router and if all the icons on it are blinking. If your mobile device still does not connect to the Internet, then the problem is in the router. To sort it out, go to the router manufacturer’s website and look for solutions to the problem; if that doesn’t work, then take it to the Service Center to have the problem fixed.

If you have problems connecting your mobile device to a wireless network, that is, Wi-Fi, follow our instructions for eliminating them, and you will definitely be able to access the World Wide Web.

It often happens that Wi-Fi on Android suddenly does not work. It is already difficult for a modern person to do without it. In a panic, the Internet user begins to think that the device has broken down. This is an erroneous but common belief. There's no need to worry. Typically, Android does not see the network for one of the following reasons:

• incorrect network security settings;
• changes in network operating conditions;
• failure in the router operating mode;
• changing the channel on which Wi-Fi operates.

A sudden loss of communication could mean that your router's settings have changed. We will not go into the intricacies of the operation of the electronic device, we will only note that the settings need to be reset to the initial ones. Simply turning off the modem for 15-20 seconds and then rebooting it allows you to establish a communication channel.

How to eliminate interference?

Unfortunately, the simple technique described above does not always solve the problem. What happens more often is that wifi stops working due to changes in network conditions. Agree: there are more and more Internet users, so each new connection can lead to the waves mutually absorbing each other under the influence of interference. Simply put, a new connection (for example, neighbors connected to the network) can disrupt your communication channel.

Even a routine reconfiguration of a neighbor's communication channel can lead to interference. There is only one way out here: change the channel for your Wi-Fi. To do this, go to the router settings, find the “Wireless” tab there. Next, you need to select a channel (not “Auto”) and save the new settings.

We remind you that the settings take effect after the router is rebooted, so we run it and try to connect. It should work the first time (for the Windows operating system), but on Android this technique does not always work; Wi-Fi still does not turn on.

Why is this happening? The factory settings of the router have a kind of protection against unauthorized connections, so when changing the channel, the devices need to be “introduced” to each other. This is where access passwords and all related settings come into play. It’s easier to “get acquainted” by directly connecting the router and mobile device via a cable connection. We switch the devices, access the Internet via a direct connection and reboot the router, having previously disconnected the devices.

All settings (passwords) on Android are saved, the modem will recognize it as a device with allowed access, Wi-Fi will work.

What to do if there is no network connection?

There is a high probability that after all the steps described above, Android sees the connection, but does not connect to the network. In this case, try connecting to the Internet from another device (a dial-up connection to a computer does not count). If the attempt was successful, then the problem is not with the router, but with your Android. Note that it should display a message: “Wifi authentication failed.” Most likely, you inadvertently reset the access passwords on your mobile device. This may have happened due to a technical glitch or minor problem. Try entering the password manually, following the keyboard layout. If this does not help, then you need to reset all settings and connect to the network as prescribed in the user manual. Save the new connection (settings) and reboot the device. After rebooting, Android should be able to access the Internet.

It is advisable for Android to start turning on after the modem has received reliable connection to the network. Router settings fail more often due to the fact that the device simultaneously tries to access the network and organize Wi-Fi distribution. The picture can be especially deplorable if the distribution is organized on several channels at once (maximum access).

Repeated failures in modem settings can be eliminated if you completely reconfigure it. You can do this yourself if you are a confident user of modern devices. Even the Russified modem settings interface does not fully guarantee that you will be able to change all the settings. In this case, it is better to contact your provider and get advice from an experienced specialist.

Lack of necessary knowledge about networks will force you to use the services of a system administrator. The same applies to changing settings on your Android: independence can cost you a lot.

Sometimes owners of mobile devices based on the Android operating system encounter a problem in which Wi-Fi does not work in some cases. We will now look at what the causes of this problem may be and how to get rid of it.

Wi-Fi does not turn on on Android: reasons

If we talk about the manifestations of such failures, then we can count plenty of reasons. However, from all this diversity, we can identify several of the most common situations that users encounter more often than others. If you make an approximate list of possible reasons why Wi-Fi does not turn on on an Android smartphone, it will look like this:

— incorrect login password;

— malfunctions in the device software;

— incorrect date and time;

— problems with settings;

— manifestation of viral activity;

- inappropriate firmware;

- incorrect router settings.

Let's try to consider a method for eliminating each problem. The solutions proposed below in most cases allow you to fix the problem 100%.

Wi-Fi not working: checking password

One of the most common causes of problems on a device based on the Android operating system is the incorrect entry of the password set when connecting to a virtual network. As should already be clear, if Wi-Fi suddenly does not turn on on an Android tablet or smartphone, and the password was automatically saved during the previous connection, then perhaps it was simply changed. To solve this problem, you need to go to the settings of the wireless module, delete the old password and enter a new one. As a last resort, you will just need to check the correctness of the input. You may have the wrong keyboard layout enabled.

Wi-Fi does not work: date and time settings

Another possible reason why Wi-Fi may not work is incorrect date and time settings on the mobile device itself. In some emergency situations this can lead to certain problems. The fix method in cases where Wi-Fi on Android does not turn on in this situation is to go into the date and time settings and, in addition to manual settings, also use the date, time and time zone of the network.

Software failures

It also happens that the causes of the problem lie much deeper. For example, there are known situations in which the Wi-Fi button does not turn on. What could this mean? Only that a critical failure occurred in the software that is responsible for the functioning of this module in the system. Practice shows that it is not always possible to automatically correct this state of affairs. For this reason, many experts recommend installing a special utility called Wi-FiFixer. This utility is notable for the fact that you don’t need to change anything in its parameters and settings. The program is simply installed on devices and launched. During the scanning process, the program can find many different problems and automatically fix them. However, this method does not always work.

Settings failure, general reset

If the previous methods did not help you fix the problem on your Android mobile device, and your Wi-Fi still does not turn on, then most likely there is a problem with the system itself or in the settings. A way to correct this situation could be a complete reset to factory settings. In the recovery and reset section, first you need to check the box next to the automatic recovery line. When the system is rebooted after a reset, all the user’s personal data and files, including applications, can be restored without any problems. Next, you just need to select a hard reset, followed by a complete reboot of the operating system. In this case, hardreset is not needed. Everything is restored perfectly, provided that the system has the original firmware and is not infected with viruses.

Exposure to viruses

The reason why Wi-Fi does not turn on on an Android device may be due to viruses. Today you can find many owners of mobile devices who do not use standard antivirus applications, believing that they seriously load system resources. There is, of course, some truth in this. But modern mobile antivirus programs can not only prevent the penetration of viruses, but also block access to the device if it is stolen or lost. If there is a problem with viruses, then you need to install the appropriate application. However, how to do this if Wi-Fi does not work? Very simple. First of all, you can download the program as an APK file from your computer, and then transfer it to the memory card of your mobile device and install it. After this, you need to perform a system check. Also, the installation must be performed directly from a computer terminal or laptop if you have a control application like PCCompanion or something else when using a gadget connection using a regular USB cable. What exactly you decide to install is up to you to decide for yourself. However, among the variety of applications, I would especially like to highlight the 360 ​​Security program. Today it is recognized as one of the most powerful. However, as mentioned earlier, it is quite difficult to recommend anything specific.

Firmware problems

Another problem due to which Wi-Fi does not turn on on an Android device may be due to incorrectly installed unofficial custom firmware. The firmware may have been originally designed for a different device model. It may also contain software flaws. Then you will have to remove it and restore the factory shell. This operation is performed differently for different devices. Only in this case it will not be possible to do without specialized software installed on a PC.

If you have chosen a mobile tariff in order to profitably call your family and friends, but using the Internet is very expensive, connecting to Wi-Fi can save the situation. But even if you have a router at home for wireless Internet distribution, this does not mean that you will be able to connect to it without problems.

Very often, users have problems connecting to Wi-Fi. It turns out that fixing this problem is quite easy. Let's take a closer look at this process.

How to establish a wireless connection

To set up a communication channel you will need a transmitter and receiver. In this case, the role of the receiver is played by the Wi-Fi module of your phone, and the role of the transmitter is an ADSL modem or any other device with which you can create an access point. Problems connecting to the Internet from a mobile phone can occur for several reasons.

1. Malfunction of the Wi-Fi module of the phone. In many modern budget devices this module is not working properly from the very beginning.
2. Impact of external factors.
3. Incorrect connection settings.
4. Software failures.

If you are unable to set up a Wi-Fi connection on your phone, first of all, check for LAN. To do this, you need to connect a laptop or desktop computer to the router. If there is no connection, you may need to check your account balance. If everything is fine with the connection, then you just need to set up Wi-Fi distribution.

In order to solve this problem, you can use the special documentation that comes with the Wi-Fi router. The agreement with your Internet provider should also describe in detail the procedure for activating the distribution. In addition, your login and password to log into the network should be indicated there. Without this data, the connection will not function.

If you're having problems with your Wi-Fi connection when you try to connect to a public network, you may need to do some adjustments on your phone.

Setting up Wi-Fi on a phone with the Android operating system

Before you start setting up, you need to make sure that Wi-Fi is active. To do this, in the “Wireless networks” item, in the list of networks available for connection, select the network you need. If you use a home router, then the identifier for accessing the network can be found in the agreement with the Internet provider. If you are using a public network, your network credentials are usually posted in plain view of visitors.

If your chosen connection is active, but you still can't figure out why you can't connect to Wi-Fi, try changing your network settings. To do this, you need to go to the connection settings menu. Problems usually occur when the IP address is set incorrectly. You need to put a marker next to the line “Install static Wi-Fi”. Next, you need to enter your network login information, which you can find from the attached documentation or receive when activating and configuring the router.

Connecting Wi-Fi on an iOS phone

The principle of operation and the algorithm for setting up the device are practically no different from those discussed for Android. In the phone settings, you need to activate the Wi-Fi module, and then select the desired network from the list of networks. If there is no Wi-Fi connection, you need to enter the IP address and change other settings.

After this, you need to save the settings and reboot the router and phone. This procedure is usually sufficient to restore the connection. Also check if you are entering the letters correctly when entering your password. Don't forget to take into account letter case and keyboard layout. This rule applies to all mobile devices, regardless of the type of operating system used.

Poor Wi-Fi connection

Even correct configuration of the Wi-Fi module and modem does not always solve the problem associated with connecting to a wireless network. The reasons for the lack of connection may also be the following:

- poor-quality phone firmware. Many users, trying to update their phone, change the firmware themselves. This action can both make working with the device easier and cause a lot of inconvenience. If you cannot connect to a wireless network due to the use of a different firmware, you will have to install the original version.
— MAC address protection is installed in the modem settings. In this case, you need to disable protection.
— network operation is affected by applications running in the background. To fix this problem, check running tasks through the manager and stop those that you do not need at the moment.

If all these methods do not bring results, you can try contacting a specialized service center, where professionals will check the functionality of the Wi-Fi module.

Wi-Fi is a technology that allows electronic devices to transmit data or connect to the Internet wirelessly. These days, the use of Wi-Fi is becoming very common and we can see this technology being used by a wide range of devices such as smartphones, tablets, gaming consoles, smart TVs, etc.

However, this technology has a number of limitations. Firstly, it is not as secure as a wired connection, but this is solved by using Protected Access Encryption (WPA2), which helps prevent unauthorized access to the network. If you do not have sufficient knowledge to set up a home or office network, then it is better to entrust this matter to professionals. Simply fill out the form at http://kompom.kiev.ua/ and the setup will be done quickly and efficiently.

Another problem: Wi-Fi drops out periodically. Usually, when there is no activity, the phone or tablet loses connection with the Wi-Fi router and does not see the network until Wi-Fi on the mobile device is restarted. There may be several reasons why the Wi-Fi connection is lost; in this article we will look at several options for solving the problem when Android loses the Wi-Fi network.

If you are facing the problem of Wi-Fi turning off on your Android device, try the following settings options and you will be able to connect your device wirelessly without much hassle.

Wi-Fi network overflow

The biggest interference to the Wi-Fi signal comes from neighboring wireless networks. The problem is that most Wi-Fi devices operate in the already occupied 2.4 GHz band, and the high density of signals can interfere with each other, reducing the speed and performance of networks.

Solution: Use a dual-band router that can operate on both 2.4GHz and 5GHz simultaneously. The 2.4 GHz frequency band will be supported by most devices, but it only has three non-overlapping channels. On the other hand, 5 GHz has 23 non-overlapping channels, increasing the likelihood of no interference in this band. If your router can operate in the 5GHz band, use it to solve your Wi-Fi network congestion problem.

Setting up a Wi-Fi channel

The 2.4 GHz Wi-Fi band has 11 channels and each of them is separated from each other by a 5 MHz band and has a width of 20 to 22 MHz. This means that each channel will overlap adjacent channels by 10 MHz and this is referred to as overlapping channels.

Solution: In the case of channels 1, 6 and 11, there will be no overlap causing interference, since these are not overlapping channels. To work on these channels, users will need to go into the router's settings and find a setting called "Channel" or "Wireless Channel". From the drop-down menu, you need to select the desired channel number.

Most manufacturers resort to various methods to increase battery life. Android smartphone users are forced to enable such power saving features in their devices. One such feature is turning off Wi-Fi when the phone is inactive or when the device has low battery. Such features of Wi-Fi in sleep mode create problems when connecting to the network as needed.

Solution: Simply configure your Android device's settings and make sure you always have Wi-Fi turned on, even when your device is not in use. To do this on devices running Android 2.3 Gingerbread and above, you need to do the following. Go to Settings menu - Wireless network— Wi-Fi and select Advanced — Wi-Fi in sleep mode do not select "Don't turn off".

On those devices running Android 4.0 ICS and higher, go to Settings - Wi-Fi, select Advanced and set the Wi-Fi during sleep option to "Always".

Change DNS servers

Changing DNS servers can solve the Wi-Fi problem when the Internet network on the phone disappears. Go to Settings - Wi-Fi and turn on Wi-Fi. If it's a known network, you'll have to "forget" it and then connect again. When you see the password entry window, click on Extra options and select "Static" from the IP settings in the dropdown menu. Then scroll down and enter the IP address of the DNS server you would like to use in the DNS1 and DNS2 field. Now enter your Wi-Fi password and connect to the network.

Reset to factory settings

If none of these methods work, hard reset your Android device. If you then have problems where you lose your Wi-Fi connection, then it could be a hardware problem. You may have to take the device to a service center to have the problem fixed.

We have looked at the most common reasons for Wi-Fi disconnection that occur in Android devices. We hope this will help solve the problem and allow you to set up a stable Wi-Fi connection. In addition, pay attention to specialized applications, since there are many applications in the Google Play store, the use of which will help ensure a reliable connection. Some of them are Wi-Fi Fixer, Fix My Wi-Fi, Wi-Fi Analyzer and others.
