Restart your Android device and Wi-Fi router

Sometimes, simply rebooting your Android device may help in resolving the Wi-Fi related problem that you might be facing. You can also try and restart your Wi-Fi router as well.

Change Wi-Fi bands
If you are connecting to a 5GHz Wi-Fi network, you can switch the Wi-Fi antenna on your Android device to look for Wi-Fi networks at that particular band. This will also help in improving the Wi-Fi performance of your Android device. Similarly, you can switch the Wi-Fi band to 2.4GHz for better performance and fix any connectivity issues that you might be facing.

To change the Wi-Fi frequency band on your Android device, head over to Settings -> Wi-Fi -> Advanced -> Wi-Fi frequency band and select the frequency that matches the one used by your router.

Remove and re-add Wi-Fi networks
In case the above methods don’t work for you, you can try and remove the Wi-Fi network from the known list of networks on your phone, and then try connecting to it again. To ‘forget’ a known Wi-Fi network, head over to Settings -> Wi-Fi and tap the name of the Wi-Fi network followed by the ‘Forget’ button.
Then, switch off Wi-Fi and switch it back on after 20-30 seconds. You should now, hopefully, be able to connect to the Wi-Fi network on your Android device.

Change the DNS
If your Android device is able to connect to a Wi-Fi network, but you are not able to browse the Internet through it despite a working broadband connection, you can try and change the DNS servers used by your Android device.

Settings -> Wi-Fi and switch on Wi-Fi. If its a known network, you will need to ‘forget’ it first.

You can now enter the password of the Wi-Fi network and connect to it.
