wifi no longer working after upgrade to 11.2

On the phone, identify the network then "Forget This Network".

Turn off router and on the phone reset network settings.

Turn on router and connect.

If you have a dual-band router, try changing to the other band.

Hi

Turn off your router for 20 /30 seconds when it's back on go to settings on iPhone down to reset Reset network settings After reset enter your router wireless key.
