Hi, wifi in my lt18i won't go on:

I updated to android ics with SUS, and nothing helped.

You may need to perform a system repair but back up all your files first

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 - 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

If it still doesn't work then contact Xperia care http://www.sonymobile.com/global-en/support/contact-us/

I did it, but nothing helped.

Now the battery shows 100% all time.
