I hate it..can't access my WiFi router..keeps saying failed to connect - no issue with my network provider, just happened straight after the update..I have tried switching both on and off.
If not already tried it might be worth going in to your WiFi settings on the phone and tell it to " forget " the existing connection and then set up a new connection for it
In order to revert back to a previous firmware version, you have to flash the old version using a PC. There are tutorials available on how to do this all over the Internet in forums and on YouTube

do a WiFi reset.. this will just clear all WiFi data and will not affect the phone, reboot the phone and then go into the connection settings. you now should see all available WiFi signals
