Anyone else still w/Wifi issue on 4S ?

[Maziar]

Hey guys
Ever since I updated my 4S to iOS 6,my wifi keeps disconnecting pretty much as soon as I lock the device and sometimes it reconnects and sometimes it doesn't(and I have to turn the wifi off and on again to make it work) I also tried iOS 6.0.1 but it didn't help.
I've also tried restoring and it didn't help either.

Anyone else having the same issue ? any fixes ?

I had this issue. Choosing "Forget this network" and then reentering the wifi details manually fixed it for me.
