Owners of mobile devices based on Android operating systems sometimes, infrequently, are true, but they face the problem that in some cases Wi-Fi does not work. With what it is connected and how to get rid of such a problem, it will now be shown.
Wi-Fi does not turn on on Android: possible reasons
As for the manifestation of such failures, their causes can be counted abundantly. However, among all their diversity, several basic situations can be distinguished that are more common than others.
If you make an approximate list of possible reasons why, for example, Wi-Fi on your smartphone (“Android” on board) does not turn on, it will look like this:
- Invalid login password
- Incorrect date and time
- device software malfunctions;
- problems with the settings;
- exposure to viruses;
- inappropriate firmware;
- Incorrect router settings.
Based on this list, we will try to consider the methodology for resolving each problem. In most cases, the proposed solutions below fix the problem, as they say, one hundred percent.
Wifi does not work: check password
One of the most common reasons is an incorrectly entered password, which is set when connecting to a virtual network.
As already clear, if the Wi-Fi on the Android tablet doesn’t turn on suddenly, and the password was automatically saved during the previous connection, it may very well be that it was simply changed. To solve the problem, go to the settings of the wireless module itself, delete the old password and enter a new one. In extreme cases - just check the input (maybe the keyboard layout has been switched).
Date and Time Settings
Another reason (albeit quite rare) is the incorrect date and time settings on the gadget itself. In some, so to say, emergency cases, this can lead to such problems.
The correction technique, when Wi-Fi on “Android” does not turn on in relation to such a situation, is to go into the date and time settings and, in addition to manual settings, use the network date, time and time zone.
Software Failures
It also happens that the problem is "buried" much deeper. So, for example, there are cases when the Wi-Fi button on the “Android” does not turn on. What is this talking about? Yes, only that a critical failure occurred in the software responsible for the operation of this module in the system.
As practice shows, it is not always possible to automatically correct this state of affairs. Therefore, many experts recommend installing a special utility called Wi-Fi Fixer. It is notable for the fact that nothing needs to be changed in its settings and parameters. The program is simply installed on the device, launched, and in the process of scanning for possible problems it fixes errors automatically. True, and this does not always work.
Failures in settings and general reset
If the previous methods did not help and Wi-Fi still does not turn on on Android, a violation in the operation of the system itself or in its settings is very likely. A correction of the situation, and at the same time a cure, could be a complete reset to the factory state.
At the same time, in the recovery and reset section, you should first check the box next to the auto-recovery line (after resetting when the system restarts, all personal data and files, including applications, can be restored without problems). Then a complete reset is simply selected, followed by a system reboot. By the way, note that in this case you will not need a hard reset, everything is perfectly restored and so on (provided, of course, that the system is not infected with viruses and has the original firmware).
Viruses
Exposure to viruses can also cause Wi-Fi to not turn on on Android. Today you can find a fairly large number of owners of mobile gadgets who prefer not to use full-time anti-virus applications, considering that they very heavily load system resources. Partly it is. However, modern mobile antiviruses can not only prevent viruses from entering the system, but also block access to the device if it is lost or stolen.
If the problem with viruses has got out, it is worth installing the appropriate application. But what if the wifi doesn't work? Yes, very simple. Firstly, the program can be downloaded in the form of an APK file from a computer, then transferred to a removable memory card and installed, and then fully tested. Secondly, installation can be done directly from a computer terminal or laptop if you have a control application like PC Companion or something else, of course, using a gadget using a regular USB cable.
What to install is already a private matter. However, among the whole variety of such applications, one can advise 360 ​​Security, which today is recognized as one of the most powerful, the same Dr. Web or McAffee. However, as is already clear, it is very difficult to advise something specific.
Firmware issues
Another reason that Wi-Fi does not turn on on Android may be due to incorrectly installed unofficial custom firmware.
Here the situation is such that the firmware can be installed without problems, but was originally designed for another model of the gadget or has programmatic flaws. Here you have to remove it and restore the factory shell. For different devices, this is done in different ways. The general thing is that without specialized software installed on the computer, you can not do here. In the simplest case, you can do it using the same universal PC Companion utility.
Router settings
Finally, it may well happen that the access settings have “flown” on the router. In this case, we are considering a situation where the owner of both the router and the mobile device is one user, and they are not connected to an extraneous private network.
Please note that in the settings of the wireless mode on the router, the parameter (“Auto”) must be set automatically in the channel selection field, “Mixed” in the mode line (11 b / g / n), and filtering must be turned off MAC Address (OFF).
If nothing helps
It remains to add that if none of the above methods gave a positive result and Wi-Fi still does not turn on, most likely, the problem lies in the Wi-Fi module itself. The device will have to be taken to a service center to conduct a full hardware test. If the problem is here, the module will have to be replaced.
