Why does it keep saying my WiFi password is wrong?

It can be frustrating when your device keeps saying your WiFi password is wrong, especially when you're sure you're entering it correctly. There could be several reasons behind this issue:

1. Incorrect Password: Double-check the password you're entering as it's case-sensitive and should match the exact characters of your WiFi password.
2. WiFi Network Changes: If you recently changed your WiFi network name or password, ensure you're trying to connect to the correct network.
3. Signal Interference: Signal interference from electronic devices, walls, or distance from the router can weaken the WiFi signal, causing authentication issues.
4. Router Settings: Your router settings may have changed, such as security protocol (WEP, WPA, WPA2) or password requirements.
5. Device Issues: Your device's WiFi adapter may be experiencing technical difficulties, preventing a successful connection.

By troubleshooting these common issues, you can resolve the problem of your device repeatedly saying your WiFi password is incorrect.
