A tablet computer is an incredibly convenient invention. With it, you can not be attached to the workplace, as is the case with stationary computing systems, and also do not carry extra pounds in the form of a full-sized laptop. However, without access to the Internet, the tablet significantly loses in flexibility of use. However, this applies to all mobile devices. In the light of this, it is quite clear that if the tablet does not see WiFi, then a similar problem should be immediately resolved.
Connection Order
The number of tablet computers running the Android operating system is ten times more than their counterparts controlled by the corresponding version of Windows or iOS. That is why in this article we will focus on mass devices. People who first encountered Android-based devices may not always be able to use wireless communications correctly. And since the Wi-Fi module is turned off in the normal state, the question arises for beginners: “Why does not the tablet connect to WiFi?” In fact, everything is quite simple. The process of joining an existing wireless network includes several mandatory steps:
- activating the transceiver module of a tablet computer;
- range scanning and selection of the desired SSID from the list;
- set of secret combination.
If the network to which you are connecting is open (Free), then the last item is not required.
How to connect a tablet via WiFi
You must open the "Application Menu", which is on any Android-device. Usually, to access it, you need to click on the circle image at the bottom of the screen. Next, carefully review all the icons and find “Settings”. After clicking on it, a window will open where there is a section "Wireless Networks".
If you specify the WLAN item, you can see the “Off / On” switch. When turned on, an automatic frequency scan will be performed and a list of detected networks will be displayed. You can also see if password access is used, and where exactly. If the network is open, then just click on its name, and the tablet will connect to it. In case of protection (WEP / WPA / WPA2), when you try to join, a password request window will be displayed. By specifying it and clicking the corresponding button, you can connect the mobile device to the network.
There is a faster way to access Wi-Fi. There’s no need to search for “Settings” for this. It is enough to slide your finger down the screen, pulling the curtain, find the WLAN (Wi-Fi) image and click on it. The module will activate, scan and list the networks.
The nuances of the alternative method
Now many owners of Android devices often replace the official custom 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 enable the Wi-Fi module through the "Settings". When using custom firmware, you should remember that in some of them there are recognized errors in working with networks. At the same time, the latest versions of Wi-Fi drivers are often integrated into the latest “self-written” software updates. The conclusion is simple: before studying a lot of information about why the tablet does not connect to WiFi, sometimes changing the firmware is enough.
The problem of standards
In order for the devices to integrate into a wireless network, it is necessary that the protocols they support are compatible with each other. So, the first models of Android tablets may simply not know how to work with WPA2 protection, supporting only WEP. In this case, changing the encoding type in the router settings may help. Another thing is true: a “clumsy” configured access point can ruin the life of the most patient owner of a modern tablet.
Interim solution
So why doesn’t the tablet connect to WiFi? There are many reasons. The simplest we have indicated above. In addition to them, the tablet’s ability to work with a wireless network is affected by the power of its transmitter.
Very often, during scanning, the desired SSID is determined, and even a password is accepted, however, it is impossible to work with such a connection. This is due to the fact that although the device “sees” the router, the data packets sent do not reach the destination. The solution is simple - physically get closer to the access point. This "disease" often affects low-cost Chinese tablets that use cheap transmitters.
Crutch program
But what should I do if, for no apparent reason, the tablet stops connecting to WiFi, although until recently everything worked fine? You can try to use the wonderful software solution distributed free of charge in the Market - Wi-Fi Fixer. After installing the application, the tablet needs to be rebooted, and subsequent connection to the network should be performed through the interface of this program, which will be displayed in the curtain. In addition, sometimes it helps to solve transmission speed problems.
Work with settings
Understanding why the tablet does not connect to WiFi, one can not help but mention possible failures in the operating system itself. Installing third-party applications, making changes to the operation of components, obtaining root-rights - all this can affect Wi-Fi. You can try to restore operability through a return to the factory settings. To do this, go to “Settings - Personal data” and use “Recovery and reset”. In this case, all user data (including the phone book, not flushed to the file) will be erased. Therefore, you first need to prepare copies.
