Q: Problem WiFi while iPhone 4S is in screen lock

Hi, I have the same problem and I don't know how resolve it :-(. So, without wifi connection , when iPhone is in standby, I don't receve any notification and it is absurd

No, I have iPhone 4S and whit iOS 5.1.1 the wifi worked also in standby. I have the problem with iOS 6, so I think that it is a software problem.

Thank you very much

Ow sorry, didn't see the thread, thank you very much I'll be checking back here tomorrow

Have the same problem?

Yep, annoying because I can't seem to receive FaceTime calls...

EDIT: I even tried a complete restore, that didn't help either...

I restored 2 times, but the problem remain. Now my iPhone don't find my wifi home network

Me too, as long as "use cellular data for FaceTime" enabled is. But when I disable that and turn my cellular data off, but wifi on, I can't receive FaceTime calls.. It used to be possible in iOS5

Hi, I will go to Apple store friday and I hope that they resolve it
