Xperia T No WiFi connection after system update

[Gucci]

Hi I'm new to this forum but in need of help - currently have smartphone that cannot connect to WiFi.  Carried out software update to Jelly Bean phone appears to work great but I cannot view, connect or switch on WiFi.  Any help would be appreciated.  Thanks

Try performing a system repair using Pc Companion as this will often fix issues - This will factory reset your phone

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
