1: Settings >> Connections >> Wi-Fi >> W-Fi network >> Tap and hold the Wi-Fi network that you're having trouble with until the menu allows you to select Forget Network.
3: Restart the Router and Mobile Device. Switch off your Router (at the wall or with the power button on the router) and wait for 2-3 minutes before switching it on. While you're waiting, press the Power button on your mobile device and select Restart.
Once the router has been successfully connected to the internet again, try to connect to your network on your mobile device.
Make sure there is no interference between the router and your mobile device. Concrete walls, fridges, and microwaves can all interrupt the Wi-Fi signal.
