What are the common reasons my phone won’t connect to WiFi?
One common reason your phone might not connect to WiFi is an incorrect password. If you’ve changed your WiFi password recently or if someone else has, ensure that you’re entering the correct credentials. You can forget the network on your phone and reconnect by re-entering the password if you suspect this is the issue.
Another reason could be that your phone’s WiFi antenna is malfunctioning or that the WiFi network you’re trying to connect to is experiencing issues. Make sure to test the WiFi on another device to rule out problems with the network itself. If the issue persists across multiple devices, your router might need a reset or reconfiguration.
How can I troubleshoot my phone’s WiFi connection?
Start by toggling the WiFi off and on again on your phone. This simple step can often resolve temporary connectivity issues. Additionally, try restarting your phone, as this can clear any software glitches that may be preventing a stable connection to the WiFi network.
