How to troubleshoot WiFi connection problems on an Android mobile

Posted on

The technology, despite having improved a lot over the years, continues to fail from time to time. It is not uncommon for mobile phones to give us problems, and WiFi can be the protagonist of some of them. Devices that disconnect just because, WiFi networks that are not recognized, slow speeds… everything has an easy solution, as long as the right settings are known.

In this little tutorial we have collected some of the most common problems with WiFi to show you how to fix them. It is enough to have access to the settings of the mobile, Internet connection and, just in case, the computer at hand. WiFi is slow (because you’re far away or your phone is working in the background)

The most common problem is the classic “WiFi is slow”. This can have two causes: first, that your mobile is doing something in the background such as updating applications or uploading files to the cloud; the second, that the router is too far away and there are too many obstacles between the room in which you are and the device.

To check the first, just take a look at Google Play and other cloud applications such as Drive, Google Photos or Dropbox to see if they are uploading something in the background. This can happen if you have not connected to the WiFi for a long time, since these apps are usually configured by default to update as soon as they detect a WiFi network. If so, you’ll simply have to pause the sync or wait a little bit for it to finish.

If it is not that, it is possible that the WiFi network does not reach certain corners of your house well. This is completely normal, especially in larger homes. The signal loses power with distance and is further diminished if there are obstacles along the way, such as walls. If that is the case, you will have to either move the router to a more central point of your house so that it reaches more or less well everywhere, or opt for a WiFi repeater.The WiFi is slow (because the 2.4 GHz band is saturated)

Typically, older routers emit only in the 2.4 GHz band, which is the band that most older smartphones are compatible with. This band is usually saturated and is very noticeable in the blocks of flats, where there are dozens of routers emitting in the same band. Each one does it on a different channel, although it is possible that yours is broadcasting on a channel very close to the rest, which can cause interference and slowness. But it can be changed.

To check which channel your WiFi broadcasts on, you simply need to download WiFi Analyzer (it’s free). When you open it, give it the permissions it asks for and let me scan the network. You will see that a graph appears with all the WiFi networks that are around you, among which will be yours. Swipe left three times and you’ll reach a tab where the app will show you the best channels by network. Select yours and let yourself be guided by the star system. In our case, the best bands are 10, 12 and 13. The 14 cannot be used in Spain.

Touch go to the computer (or from the mobile browser if you prefer) and access our router. To do this, you just have to enter the address 192.168.1.1 in the URL field. Access with your credentials, look for the “Channel” or “Channel” option, depending on the router you have, and change it to the one with the most stars in the application. Once this is done, restart the router and voila, you will notice an improvement in speed.

If your router and mobile are newer, both may support the 5 GHz band. In that case, access your mobile’s WiFi settings and search for your network. If two are the same, but one of them is “netname (5 GHz)”, connect to it. The speed is much higher and you will notice a palpable change. It’s also possible that your router is configured to broadcast on both bands at once but on a single SSID. If so, your mobile will automatically connect to the best, so you won’t have to touch anything. The mobile does not connect to the WiFi

If the problem you have is that your device doesn’t connect to the WiFi network, there are several things you can do. First of all, have you checked that the WiFi is turned on? Lower the notification curtain and make sure it’s turned on. If not, click on the icon and let the mobile analyze the networks. It will connect right away.

For X reasons, your phone may have forgotten your WiFi network password. This is easy to check. Simply go to “Settings” > “Wireless connections and networks” > “WiFi” and search for your network. If it appears but does not connect, tap on it and enter the password again. If you don’t remember it, and if you haven’t previously changed it, you can find it on a sticker under the router.

If you see a message like “Saved network” but you’re still offline, chances are you’ve mistyped the key. Tap on it, select “Forget Network” and try to connect again. The mobile does not detect the WiFi network

If this is the case, things can get serious. If your mobile, even being close to the router, does not detect the WiFi network, it is possible that the router has a problem. The first thing you need to do is to restart all the devices. The mobile is simple, you simply have to press and hold the power button and press “Restart”. The router must be turned off, disconnected from power and wait 30 seconds. Once that’s done, reconnect it and turn it on.

If you still don’t have access to your WiFi network, try going to “Settings” > “Wireless connections and networks” > “WiFi”. Go down and select “Add Network”. Enter your network name carefully, under security select “WPA/WPA2 PSK” and finally enter the password. If you don’t even connect for those reasons, it is possible that the router itself is to blame. In that case, it is best to call your company to send a technician who can help you.

It is also important to note that your router may broadcast in the 5 GHz band and your mobile may not be compatible with it. If so, this network will not even appear in the settings, so, unfortunately, the only thing you can do is renew your smartphone for a more advanced one. WiFi randomly turns off and on

If you are noticing that the WiFi of the mobile turns off and on without ton or son, it is possible that there is some failure at the system level. If it’s a problem you’ve noticed repeatedly, the most sensible thing to do is to back up your data and then a factory reset.

To do this, head to “Settings” > “Backup & Restore” and reset the device data. If this does not solve it, the only thing left is to send your mobile to the technical service.
