No matter how fast the modern Mobile Internet, Wi-Fi connection is still a priority for most users. However, it is not more pleasant to encounter problems with this very connection, when the device either does not connect to Wi-Fi at all, or connects, but there is no Internet. In such situations, you should check the following basic points and settings.

1) On your Android device, go to Settings > Wi-Fi, select the network you are trying to connect to and click Forget or Delete. This is necessary if the network you are trying to connect to has a common or universal SSID. For example, some popular network coffee shops may have the same chain name for different places, but at the same time have different password to connect. In this case, the Android device tries to use the password that was suitable earlier.

2) When trying to connect to home router The first step in troubleshooting any problems is to reboot it. If none of the connected devices can access the Internet, contact your ISP.

3) If you are convinced that the Internet is functioning normally, but only your Android device cannot connect, then check the security settings used by your router. First try disabling them completely, if this fixes the situation, then try different security protocols (WEP, WPA-PSK, WPA2-PSK, TKIP, AES)

4) Turn off the QoS function in the router settings. She is responsible for intelligent distribution throughput channel between devices. For example, if at home there is game console or a TV with streaming streaming services, the router will give priority to connecting to them, cutting off the speed of other connections.

5) Disconnect USB peripherals from the router. If you connected to your router HDD or any other USB device, and the port is not shielded, this may result in signal reception in the 2.4 GHz range.

6) Speaking about the signal range, if you have dual band router operating at a frequency of 2.4 GHz and 5 GHz, specify in the settings to force the use of one of the bands. If you have a relatively old device, then it may simply not support operation at 5 GHz.

7) When connected to public networks Remember that they all require pre-authorization before providing internet access. Having connected to such a network, try to open any tab in your browser, the system should automatically redirect you to the authorization page. Make sure you haven't prohibited work system process CaptivePortalLogin, which is responsible for the appearance of the authorization window. You can do this in Settings > Applications.

10) Turn off the Wi-Fi tethering function.

Authentication problems often (but not always) arise from password issues. The device tries to check/authenticate the password you use to log into your WiFi network, and if the password is incorrect, it fails authentication and displays an authentication error message.

Below are all the methods we know of to solve this problem, supplemented by user solutions from the comments.
We recommend that you follow the instructions step by step, no matter how banal these actions may seem.

Authentication error when connecting to wifi on Android: what to do

Step 1: Password is correct

Passwords protect your network from unauthorized access; if you enter an incorrect password, you will not be able to establish a connection. Even if you know your password and are confident in it, there is a chance that you are entering it incorrectly. The password is case sensitive (lowercase and capital letters), so if you have capital letters or Special symbols, make sure you enter them exactly.
Check the “Show password” box to ensure that you entered it correctly.

Step 2: Check the network name

Another thing that might seem obvious, but you can get it wrong, so make sure you're trying to connect to the right network, network names can be similar and differ slightly and can easily be confused. Either way, check and make sure you are connecting to the correct network.

Step 3: Reboot your router

There may be technical problems in the router (router), software problems, so turn off your router(s) for a few minutes and turn it on again.
Before entering your password, remove the network (that you are connecting to) to ensure that Old Password not saved anywhere. To do this, click on the name of your network and hold for 2-3 seconds, a menu will appear.

Step 4: Change the network security protocol

Try changing the security protocol in the network settings on the router, for example, if it is WPA, change it to WPA2 and vice versa. Then try connecting to a Wi-Fi network.
There is a possibility that your phone, due to hardware limitations or firmware flaws, may not work correctly with one or another security protocol. But for this you will have to change the settings WiFi connections, if you do not have sufficient knowledge, it is better to skip this point.
As a replacement, try finding another phone and try to connect.

Step 5: Use a Static IP Address

1. Go to Android settings;
2. Open Wi-Fi;
3. Find the network you need here;
4. Long press on a title WiFi networks, a menu with advanced settings will open, where you need to select “Change network”;
5. Change the IP setting from DHCP to Static, that is, we change the operating mode, now the router will not assign us an IP address, but we will assign it manually;
6. Now enter assign IP address 192.168.1.*** (add any number from 1 to 225 in ***). The address you enter depends on the model and settings of your router and provider. It's better to check with knowledgeable specialist. As an option, the default router addressing for popular models you can see

Note!
If, on the contrary, you had a static IP address by default, change it to dhcp so that the router itself assigns the desired address

Step 6: Removing Outdated Files

Only for devices with root access

1. Download and install ES File Explorer or Total Commander on your device;
2. When prompted, give them root permissions;
3. Go to Root explorer from the menu;
5. Go to /data/misc/dhcp/ ;
6. Delete all files there;
7. Restart your device and try to see if the problem is resolved.

No Internet: what to do?

Below are the options when there is no Internet on an Android phone, but this is not related to authentication.

Switch to airplane mode

This works on some phone models. Turn on airplane mode, wait 10 seconds and turn it off.

Is Bluetooth turned on?

Bluetooth can create a conflict with Wi-Fi (due to a factory defect or incorrect firmware), since some users have noted that on some phones, when Bluetooth is turned on, Wi-Fi does not work. So if you have bluetooth turned on, then why the hell not, turn it off and check the connection.

Energy saving mode

Power saving mode is designed to reduce the phone's battery consumption. Since, as you know, turned on Wi-Fi quickly drains the battery, so turning on the power saving mode can turn off your Wi-Fi (it all depends on the device model and firmware version). Make sure power saving mode is turned off. You can access energy saving mode on the menu Settings/Battery your phone.
