After upgrade to iOS 6 i am not able to use wifi.

Connected, but no wifi traffic (at home).

After upgrade to iOS 6 i am not able to use wifi. I am connected to my home wifi but no trafic is coming through (safari, skype, twitter, app store). I have even tried recovery of my iPhone 4S using iTunes as well as using iPhone. But without effect.

Can not connect at all (at work).

Thank you for helpfull advice.

Please do not give me advice like:

switch proxy to auto

turn the flight mode on and off

turn the iphone on and off

release the ip

recovery the network settings

recovery firmware

I have tried all these, but did not work.

PS to apple:

I really did not expect this kind of trouble. If I would want to waste my time "repairing my device", I would buy an android phone!!!!!!
