A wireless network and mobile devices running an operating system Android are inseparable things. Without one, the second loses all meaning. Such technologies have become so deeply embedded in everyday life that we feel uncomfortable being deprived of these benefits. So it's important to know what to do if Wi-Fi won't turn on at Android. This is what will be discussed below.
Causes of the problem
There can be quite a few reasons why Wi-Fi does not turn on on Android – phone or tablet:
- failure in software (software);
- failure in the parameters of the phone / tablet (possibly as a result of the installation of a malicious program);
- installation of unsuitable (non-optimized) firmware;
- the presence of a virus;
- hardware error.
Quite often, users confuse the concepts 'Doesn't connect' and 'Doesn't turn on'. In the first case, the adapter itself may turn on, but it does not connect to the network. This can happen for a variety of reasons. In the second case, Wi-Fi is not turned on on the Android – tablet, that is, the adapter itself. This is what will be discussed. However, first you need to figure out why the device cannot connect to Wi-Fi.

Invalid password
The most common problem due to which the device cannot connect to the network is an incorrectly entered password. You just have to be careful. But if you have already entered the password, and the phone has memorized it, then how to change the code? It's simple: go to the device settings, go to the 'Wi-Fi' section and turn on the adapter. Next, we find our network and hold our finger on it until an additional menu appears. Here we can choose between two options:
- 'Delete network' – the next time you connect, you will have to re-enter the password.
- 'Change network settings' – in this case you can manually change the connection settings, including setting a new password.
Both options can solve the problem, so choose the one that works best for you.
There are other reasons why a device cannot connect to home Wi-Fi. They are already contained in the parameters of the router. However, the router should be rebooted first. But that's another topic. If you do not remember the key to your network, the article 'How to find out the password for Wi-Fi on Android' will help you.

Failure in software
The operating system Android is relatively young and actively developing, therefore it is not fully optimized and various failures can occur in it quite often. As a result, the operation of certain tools, including the operation of the Wi-Fi adapter, is disrupted. In this case, you need to understand that the adapter itself is working normally, the failure occurs precisely in the software part that should control the adapter.
If you find that Wi-Fi on Android won't turn on due to the button being inactive, this is the first sign of a software glitch. In this case, it is recommended to do a factory reset. The fact is that all system files and folders on smartphones and tablets are closed, and ordinary users do not have access to them. Therefore, any manual settings are excluded.
To gain access, you will need root-rights, which, by the way, open the path to system files not only for the user, but also for malicious applications and viruses. This option is not for beginners.

Errors in settings
It is not uncommon for the Wi-Fi not to turn on on Android due to a failure in the device settings. Such failures can also occur as a result of the installation of malicious applications that have access to Wi-Fi settings. In this case, you can try to find and remove the program that is causing the problem. As a rule, they are associated with Wi-Fi, – programs for hacking networks, for diagnostics and troubleshooting, for distributing a network from a phone, etc.
It is important to understand that removing such a program does not always solve the problem. Often you have to do a factory reset to get all the settings back to their places. Therefore, be careful when installing such software on your phone. Remember that physical (hardware) parameters cannot be improved by any program. Do not believe that the application is capable of hacking networks, increasing connection speed, longer range, etc. All this is cheating, and the installed software will only lead to additional problems.

Inappropriate firmware
This is another reason why Wi-Fi on the phone does not turn on Android. It's no secret that installing firmware on a phone or tablet is a fairly simple task – there is a lot of information on this topic on the Internet. And the firmware itself is not a problem to download, but not every one will work correctly. Many 'experts' post unfinished and unoptimized versions Android on their sites. Of course, such an operating system is not capable of working properly, and sooner or later you will face some pretty serious problems.
If you have installed custom firmware and are wondering why Wi-Fi does not turn on at Android, know – the reason is in the operating system. Install the official service version. Everything will work as expected in it. This is the only solution to this problem.

The presence of a virus
Viruses are another cause of wireless network problems. However, you should understand that devices running the operating system Android are initially immune to viruses. This is due to the peculiarities of the OS. Rather, the fact that all system files and folders are locked, and the virus simply cannot get into the environment in which harm can be done. But this does not mean that you are completely safe.
Quite often, users open root rights, which give full access not only to the owner of the gadget, but also to malware and viruses. And in this case, the virus can cause significant harm, up to the destruction of the components of the motherboard. To avoid such problems, it is not recommended to open root rights, as well as download and install applications from unverified sites.
It is also worth understanding that antivirus software that is advertised and offered on Google Play will not work properly, it will not work at all. Yes, it is useless if you follow the above rules.

What to do
Above, we discussed several reasons why Wi-Fi does not turn on on the phone. All this is of a software nature and, as a rule, is solved by resetting to factory settings or, as in the case of custom firmware, reinstalling the operating system. However, these are not all reasons for the problems with turning on the adapter.
If you've tried all of the above, but nothing seems to work, you can conclude that the problem is hardware-based. This means that everything is in order with the software part, the Wi-Fi adapter itself is out of order. In this case, the solution is to replace the wireless module. In this situation, it is better to trust the professionals – take the device to a service center.
So now you know what to do if Wi-Fi won't turn on at Android.
