Why does not the tablet connect to WiFi and what should I do with it?

The tablet computer is an incredibly convenient invention. With it, you can not be attached to a workplace, as in the case of stationary computer systems, and also do not carry extra pounds in the form of a full-size laptop. However, without having access to the Internet, the tablet significantly loses its flexibility of use. However, this applies to all mobile devices. In light of this, it is quite clear that if the tablet does not see WiFi, then such a problem should be solved immediately.

Connection procedure

The number of tablet computers running the Android operating system is tens of times larger than their counterparts controlled by the corresponding version of Windows or iOS. That is why in this article we will talk about mass devices. People who first encountered Android-based devices can not always use the wireless connection correctly. And since the Wi-Fi module is turned off in the normal state, the newcomers have a question: "Why does not the tablet connect to WiFi?" In fact, everything is simple enough. The process of joining an existing wireless network includes several mandatory steps:

• The use of the transceiver module of the tablet computer;
• Scan the range and select the desired SSID from the list;
• Set of secret combination.

If the network to which the connection is made is open (Free), then the last item is not required.

How to connect your tablet over WiFi

You need to open the "Application Menu", which is on any Android-device. Usually, to access it, click on the circle image at the bottom of the screen. Then carefully look through all the icons and find the "Settings". After clicking on it, a window opens where there is a section called "Wireless Networks".

If you select WLAN, you can see the "Off / On" switch. When enabled, automatic scanning of frequencies and output of the list of detected networks will be performed. You can also see if the password is accessed, and where. If the network is open, then just click on its name, and the tablet will connect to it. In the case of the same protection (WEP / WPA / WPA2), when prompted to join, a password request window will be displayed. By selecting it and clicking the appropriate button, you can associate the mobile device with the network.

There is a faster way to access Wi-Fi. There is no need to search for "Settings". Just drag your finger down the screen, pulling the shutter, find the WLAN image (Wi-Fi) and click on it. It will activate the module, scan and issue a list of networks.

Nuances of an alternative way

Now, many owners of Android-devices often replace the official firmware firmware (made by craftsmen). As a result, not all functions work in the usual way. For example, if you use the call through the curtain, then often the tablet does not see WiFi. The list of detected networks is simply not displayed.
Therefore, in such cases, you must turn on the Wi-Fi module through the "Settings". When using custom firmware , remember that in some of them there are recognized errors in working with networks. At the same time, the latest "self-written" software updates often integrate the most "fresh" versions of Wi-Fi drivers. The conclusion is simple: before you learn a lot of information about why the tablet does not connect to WiFi, sometimes it's enough to change the firmware.

The problem of standards

In order for devices to unite in a wireless network, it is necessary that the protocols they support are compatible with each other. So, the first models of Android-tablets can simply "not know" how to work with WPA2 protection, supporting only WEP. In this case, you can change the type of encoding in the settings of the router. It's also true: a "clumsy" customized access point can spoil the life of the most patient owner of a modern tablet.

Intermediate solution

So why does not the tablet connect to WiFi? There are many reasons. The simplest we mentioned above. In addition to them, the ability of the tablet to work with a wireless network is affected by the power of its transmitter.

Very often when scanning, the desired SSID is determined, and even a password is accepted, but it is impossible to work with such a connection. This is due to the fact that, although the device "sees" the router, the sent data packets do not reach the addressee. The solution is simple - to physically approach closer to the access point. This "disease" is often affected by inexpensive Chinese tablets, which use penny transmitters.

Crutch program

But what to do if, for no apparent reason, the tablet ceased to connect to WiFi, although until recently everything worked fine? You can try to use the wonderful software solution, free of charge distributed in the Market, - Wi-Fi Fixer. After installing the application, the tablet needs to be rebooted, and the subsequent connection to the network is performed through the interface of this program, which will be displayed in the shutter. In addition, sometimes it helps to solve problems with the transmission speed.

Working with settings

Understanding why the tablet does not connect to WiFi, you can not fail to mention the possible failures in the operating system itself. Installing third-party applications, making changes to components, getting root rights-all this can affect Wi-Fi. You can try to restore the efficiency by returning to the factory settings. To do this, proceed to "Settings - Personal Data" and enable "Restore and Reset". In this case, all user data (including the phonebook, not dropped into the file) will be erased. Therefore, you must first prepare a copy.
