On Android does not turn on Wi-Fi: possible failures and methods for eliminating

The owners of mobile devices based on Android operating systems sometimes, infrequently, really, but face the problem that in some cases Wi-Fi does not work. What it is connected and how to get rid of such a problem, now will be shown.

On Android does not turn on Wi-Fi: Possible Causes

As for the manifestation of such failures, their reasons can be consistent. However, among all their diversity, several basic situations can be distinguished, which are more often found.

If you make an approximate list of possible reasons for which, for example, Wi-Fi does not turn on on a smartphone ("Android" on board), it will look like this:

• incorrect entry password;
• incorrect date and time;
• malfunctions in the work on the device;
• configuration problems;
• impact of viruses;
• inappropriate firmware;
• incorrect router settings.

Based on this list, let's try to consider the method of eliminating each problem. In most cases, the proposed decisions correctly correct the problem, as they say, one hundred percent.

Checking the password

One of the most common causes is an incorrectly entered password, which is installed when connected in a virtual network.

As it is already clear if the Wi-Fi is not turned on on the Android tablet, and the password for the prior connection was saved automatically, it may very much that it was simply changed. To solve the problem, go to the settings of the wireless module itself, remove the old password and enter a new one. In extreme cases, it is easy to check the input correctness (the keyboard layout has been switched).

Setting date and time

Another reason (although quite rarely found) - improper dates and time settings on the gadget itself. This in some, so to speak, insensitive cases can lead to such problems.

The correction technique when Wi-Fi does not turn on on Android in relation to this situation, it is to go to the date and time settings and, in addition to manual installations, use the date, time and time zone of the network.

Failures of the software

It also happens that the problem is "buried" much deeper. For example, there are cases when the Wi-Fi button does not turn on on Android. What does it say about? Yes, it is only a critical failure in software that is 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 noteworthy in that it does not need to change anything in its settings and parameters. The program is simply installed on the device, starts, and during the scanning process for possible problems, errors automatically corrects. True, and it does not always work.

Failures in settings and general reset

If the previous methods did not help and on Android does not turn on Wi-Fi, is still very likely to violate in the system itself or in its settings. Correction of the situation, and at the same time and the medicine can be a complete reset of the parameters to the factory state.

At the same time, in the Recovery and Reset section, you must first check the box in front of the row of the route (after resetting the system again, all personal data and files, including applications, can be restored without problems). Then the full reset is simply selected, after which the system is rebooted. By the way, notice, in this case you will not need Hard Reset, everything is greatly restored and so (provided that the system is not infected with viruses and has the original firmware).

Viruses

The impact of viruses can also be the reason that Wi-Fi is not included on Android. Today you can find a sufficiently large number of mobile gadget owners who prefer not to use regular anti-virus applications, believing that they are very much loading system resources. Partly this is. However, modern mobile antiviruses are capable not only to prevent viruses penetration into the system, but also block access to the device in case of loss or theft.

If I got out the problem with viruses, you should install the appropriate application. But how if Wi-Fi does not work? Yes, very simple. First, the program can be downloaded as an APK file from a computer, then transfer to a removable memory card and set, after which you fully check the system. Secondly, the installation can be made directly from a computer terminal or laptop if there is a control application like PC Companion or something else, naturally, using a gadget connection using a conventional USB cable.

What to install, this is a personal matter. However, among the entire variety of this kind of applications, it is possible to advise 360 \u200b\u200bSecurity, which today is recognized as one of the most powerful, the same Dr. Web or Mcaffee. However, as it is already clear, it is very difficult to advise something concrete.

Problems with firmware

Another reason for the "Android" does not turn on Wi-Fi, may consist in incorrectly installed unofficial

Here the situation is such that the firmware may be installed without problems, but initially designed for another model of the gadget or has shortcomings of a software nature. Here you have to delete it and restore the factory shell. For different devices, it is done in different ways. The overall only is that without a specialized software installed on the computer, it is not necessary to do here. In the simplest case, you can do with the same universal PC Companion utility.

Router settings

Finally, it may well happen that the access settings "flew" on the router. In this case, we consider the situation when the owner and the router, and the mobile device is one user, and is not connected to an outsider private network.

Note at that time that in the wireless mode settings on the router in the channel selection field there must be automatically parameter ("Auto"), in the mode string - "mixed" (11 b / g / n), and filtering should be turned off MAC addresses (OFF).

If nothing helps

It remains to add that if none of the above methods of positive results gave and still does not turn on Wi-Fi, apparently, the problem consists in the Wi-Fi module itself. The device will have to be attributed to a service center to carry out the full test "Iron". If the problem is here, the module will have to be replaced.
