I have tried restoring to factory settings, but after upgrade of GO to ICS, my wifi cannot even turn on, it will say "turning on WIFI" then nothing happens. Even tried qwertyas38 suggestion to type *#*#7378423#*#*, when i choose to test WIFI, it is also stuck at "turning on WIFI".
Does this mean somehow after upgrading to ICS, my GO's WIFI module has stopped working? Hardware issue?
Only work on my old wifi router,hi-speed can't detect too.
i've tried repair function,backup and restore....also my apps in playstore.
done all test at #*#7378423#*#, some will stuck. dun bother, restart phone & i try GPS wif wifi 'on' outside my hse, detected my location.

But.....these few days, try other places all not working....

All lagging again,can't even ans calls.Got to call back,sometime ok
