I don't understand most of the replies, so lets try the basic

1. repair your phone with either pcc or sus
2. do NOT install any antivirus, taskiller, battery app, etc
3. do NOT enable stamina mode

thanks for the info!

this is a summary of the problems that we have encountered... :

the  main problem is that the WIFI is not working for anybody in our region(Middle East) this happened following the OS update ob  "Xepira" J to "android 4.1.2".

The information that you provided does not solve our our problem there is somthing more basic we thing somtheing that happened following that OS update.

I would like to point oiut that everything else is  working fine except for the WiFi!!

Could it be that the regional ROM has some sort of a  problem!

I had to go back to Android 4.0.4, and I hope Sony can offer a complete and correct ROM for Xperia j

[Uliwooly]

it could be a regional issue, but I've seen major updates before and most of the issues are resolved once the users re-install the OS
