I tried every authentication mode and channel and 802.11 setting(that i have, b only, g only, b+g), but can't get it working.(except non secured and WEP) But i didn't tried another router yet. I'll try that.

I repaired with PCC but I can't find repair section in SUS but, in SUS reinstalling means repair, am i right? I did it. Nothing changed. Maybe i should change my router. I'm going to look another wifi and try later.

I have the same problem after upgrading to ICS, wifi keeps trying to connect->Connects-> and then disconnects. Wifi was working fine on GB. If I try to connect to another wifi network in range it is sometimes able to connect to my own network afterwarts and stay connected. But the next time I get out of range and it has to reconnect it gets into the loop again.

I have seen the problem on several different networks ( routers ), but in different degree, some networks work most of the time, others almost never work.

I have repaired the SW after the upgrade without any change.

I hope that Sony is able to find and fix the problem.

I have just tried to change my wifi network to "No security" or WEP, then my phone connected without any problems.
