The "Android" does not include wi-fi: possible failures and methods for eliminating them

Owners of mobile devices based on "Android" operating systems sometimes, infrequently, however, 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, now it will be shown.

The "Android" does not include wi-fi: possible reasons

As for the manifestation of such failures, their causes can be counted abound. However, among all their diversity, there are several basic situations that occur more often than others.

If you compile an approximate list of possible reasons why, for example, do not include wi-fi on the smartphone ("Android" on board), it will look like this:

• Incorrect login password;
• Wrong date and time;
• Malfunctions in the work of the device;
• Problems with settings;
• Exposure to viruses;
• Unsuitable firmware;
• Incorrect router settings.

Proceeding from this list, we will try to consider a technique of elimination of each malfunction. In most cases, the proposed solutions correct the problem, as they say, one hundred percent.

Does not work wi-fi: check the password

One of the most common reasons is the incorrectly entered password, which is set when connected to a virtual network.

As it is already clear, if wifi on the "Android" tablet does not turn on, and the password for the previous connection was automatically saved, it could 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 correctness of the input (the keyboard layout could be switched).

Date and time settings

Another reason (although quite rare) is the wrong date and time setting on the gadget itself. This in some, so to speak, supernumerary cases can lead to such problems.

The method of correction, when the wi-fi on "Android" does not turn on in this particular situation, is to enter the date and time settings and, in addition to manual settings, use the date, time and time zone of the network.

Software Failures

It also happens that the problem is "buried" much deeper. For example, there are cases when the wi-fi button on "Android" does not turn on. What does this mean? But only that in the software responsible for the functioning of this module in the system, a critical failure occurred.

As practice shows, it is not always possible to automatically fix this state of affairs. Therefore, many experts recommend installing a special utility called Wi-Fi Fixer. It is noteworthy that its settings and parameters do not need to be changed. The program is simply installed on the device, starts, and during the scan for possible problems corrects errors automatically. True, and this does not always work.

Settings malfunctions and general reset

If the previous methods did not help and the Wi-Fi does not turn on on Android, it is very likely that there is a violation in the operation of the system itself or in its settings. A complete reset of the parameters to the factory state can be a remedy of the situation, and at the same time a remedy.

In the recovery and reset section, first check the box next to the auto-recovery line (after resetting when the system is rebooted, all personal data and files, including applications, can be restored without problems). Then you just select a full reset, and then reboot the system. By the way, mind you, in this case you do not need hard reset, everything is perfectly restored and so (provided, of course, that the system is not infected with viruses and has the original firmware).

Viruses

The impact of viruses can also be the reason that the "Android" does not include wi-fi. Today, you can find quite a lot of mobile gadget owners who prefer not to use regular anti-virus applications, believing that they are very heavily loaded system resources. Partly so it is. However, modern mobile antiviruses can not only prevent the penetration of viruses into the system, but also block access to the device if it is lost or stolen.

If you have a problem with viruses, you should install the corresponding application. But how if wi-fi does not work? Yes, it's very simple. First, the program can be downloaded as an APK file from the computer, then transferred to a removable memory card and installed, and then fully tested by the system. Secondly, the installation can be made directly from a computer terminal or laptop with a management application such as PC Companion or something else, of course, using a gadget connection using a conventional USB cable.

What to install, this is a personal matter. However, among all the variety of such applications, you can advise 360 Security, which today is recognized as one of the most powerful, the same. Web or McAffee. However, as it is already clear, it is very difficult to advise something concrete.

Problems with the firmware

Another reason that does not include Wi-Fi on Android is that it may consist of incorrectly installed unofficial custom firmware.

Here the situation is that the firmware can be installed without any problems, but it is initially designed for another gadget model or has software shortcomings. Here it is necessary to remove it and restore the factory shell. For different devices it is done in different ways. The only common thing is that without specialized software installed on a computer, it's indispensable here. In the simplest case, you can do it with the same universal utility PC Companion.

Router settings

Finally, it may well be that the access settings are "routed" on the router. In this case, we consider a situation where the owner of both the router and the mobile device is one user, and no connection to an extraneous private network is made.

Note that in the settings of the wireless mode on the router in the channel selection field, the parameter (Auto) must be set automatically, the mode line should be Mixed (11 b / g / n), and filtering should be disabled MAC addresses (OFF).

If nothing helps

It remains to add that if none of the above methods of positive result is given and still does not include wi-fi, apparently the problem is in the module itself Wi-Fi. The device will have to be taken to some service center in order to conduct a full "iron" test. If the problem is here, the module will have to be replaced.
