Reasons for the inability to contact Wi-FI and methods for solving it

This kind of behavior is not typical, and most of it is due to software problems: improperly configured phone or the router itself, as well as problems with the firmware of both. Hardware incompatibility may also occur - alas, this happens. Let's go in order.

Reason 1: Invalid dot password

The most common cause of problems with Wi-Fi, which causes banal carelessness. As a rule, Android devices report that they cannot connect to the point if the password is entered incorrectly.
The algorithm of action is this.

1. Go to "Settings" by any available method - for example, a button in the status bar.You are looking for connection settings, and they have the Wi-Fi item (as a rule, it is located very first, so it is impossible not to notice it).

Tap on it 1 time.

2. Get a list of available networks. Find the right one and make a long tap on it. Get such a popup.

In it, select "Change network configuration."

3. Get a window where the system allows you to change the password. The latest versions of Android allow you not to enter it blindly - just check the "Show password" item.

Enter the correct password and click "Save."

4. After these steps, the device should correctly determine the network and connect to it.

If the problem is still observed, proceed to the following points.

Reason 2: Incorrectly configured protection type in the router

Also a fairly common cause of Wi-Fi connectivity issues. This is especially true of older routers, which may not support some types of secure connections. You can fix this problem like this.

1. Look in the router’s user manual for the login address of the web management interface. If there is no manual, then, as a rule, there is a sticker with the specified address on the router itself. It in most cases consists of numbers, and looks, for example, like this.
192.168. *. *
Instead of the characters “*” there will be a digit from 1 to 9.

2. Open a browser (any one will do) and in the address bar enter the address you learned. The authentication main page should load.

The login and password for the web interface in most cases is the word "admin". If it doesn’t work, study the instructions and the router itself in more detail - the default login and password must be indicated there!

3. Log in.

1. Further actions: find the Wi-Fi connection settings in the menu. As a rule, it is called “Wireless LAN”, “WLAN Settings”, simply “WLAN” or, if the interface is Russified, “Wireless Network / Networks”.

Click on it 1 time with the mouse.

2. A window will open.

Look for a setting in it that contains the word "Encryption" or "Encryption Type". As a rule, it is combined with a drop-down menu.

In this drop-down menu, select the protection type “AES”. Remember to save the changes.

3. You may also need to restart the router. This can be done directly from the web interface.

A simple power off of the router for 10-20 seconds will also help.

If the reason for the problems with Wi-Fi was in the wrong encryption, then the next attempt to connect the Android device to the point should be successful.

Reason 3: Incorrect channel settings on the router

This time, the router has broadcast on a channel that is not supported by your device. You can fix it this way:

1. We go to the web interface of the router, in it - to the wireless settings (see Reason 2).
2. Look in the settings for an option that contains the word "Channel" or "Channel".

In the drop-down menu, the automatic channel switching mode should be set - in this case, the router itself selects the appropriate one. If something else is set, we recommend that you select automatic mode.

3. After that, do not forget to save the changes and reboot the router.

Reason 4: Problems with Android firmware

Another common reason for not being able to connect to a Wi-Fi point is custom firmware. The fact is that often third-party system software for smartphones and tablets do not have proprietary certified drivers. In the best case, there will be substitutes written by enthusiasts, in the worst - they may not be at all. Therefore, if you use third-party firmware, we recommend that you first read the list of possible bugs. If you find “inoperable Wi-Fi” or “Wi-Fi outages” in them, then it’s better to change this software. If you use the official firmware, perhaps resetting the device to factory settings will help you.

Reason 5: Problems with the firmware of the router

Most modern routers also have their own firmware. If you have had this for a long time, then most likely the old firmware is installed on it, which may not be compatible with the communication standards used in Android. The router also lends itself to self-firmware, but the algorithm of actions differs for each device, so we do not give it here. If you are not sure that you are able to independently reflash the router, contact a specialist

Reason 6: Hardware Failure

A rare but most unpleasant cause of malfunctions. It’s easy to check the router - if the problem is with it, then other devices (for example, a desktop computer, laptop or other phone, tablet) will also not be able to connect. A malfunction of the Android device itself can be determined by the fact that neither a reset to the factory settings nor a flashing yielded results. In the case of a broken router, the easiest way is to purchase and install a new one (trying to repair them is unprofitable), and in case of a malfunctioning device, take it to the service.

Fortunately, most of the reasons described above are software, and are solved independently.
