Hello..
I updated my xperia sl phone to jelly bean then a wifi problem appeard once the update is done ... when I swich wifi on it doesn't work .. even scaning for networks doesn't work until I remove my sim card from the phone ..
so here is the proplem: no wifi while the sim is set in the phone...
I tried many ways like restarting phone, factory resett or safe mode launch ...
Infact by searching on google for this problem you'll see that this problem apeared with alot of xperia sl devices .
