[#1]

Hi,

I've just upgraded my Xperia S from Android 2.3.4 to 4.0.4, and i've got problem with wifi connection. 

At first boot after upgrading, i could connect to the Wifi normally, but when i restart my phone, I can't browse or anything.

Wifi is connected but i can't access to internet.

I don't think it's the problem with router because i could connect to it at first, and i didn't change anythings with the router.

Please give me any solutions. 

Thanks you!

When I made the same update to my Xperia ARC everything stopped working. Phone is slow and crashes constantly, apps won t start or crash, same problem with wifi, et cetera.

Can I undo this update? :S

Same here, and I'm really irritated...
Last time I updated my e-mail where removed from the phone if it was'nt on server no more...
This time I have no option to connect to PC without using a cable....

So every update has been I giant step backwards.
Even the new layout is "cheap"

If Android 4.0.4 is possible to remov, I will !

Nobody does not help?

read the replies to this page, you'll find the solution... it's an ICS problem across the board, blame Google... (something like have an unprotected wifi, connect phone to it, then connect to your normal wifi)

You all must give software repair a try

________________________________________________________________

Backup everything as it will erase all data on phone (sms, contacts,apps)

Update/Repair your phone via PCC or SUS

Do it as follow >> PCC > SUPPORT ZONE> SOFTWARE UPDATE> REPAIR SOFTWARE (written with blue)

First do the repair \
