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

Can you post your findings back here? I live in Belgium and there is no Apple Store here

Of course, but you must wait friday :-)

Thanks and that's no problem at all

Perfect. See you soon

Turn off ask to join networks in the wifi settings.

That worked for me!

I had the same issue with all my apple mobile devices. I had tried all the solutions from applecare but none of them works for me. Finally, I called Bright House(my ISP). And, they came and replaced the Mode and wifi router. Then, everything just goes fine. For my situation, I would say the problem should be the old WiFi router! But, I still have an question. Why does iOS5 work just fine with the old router, not the iOS6? Anyway, I got everything working right now with the new router.

exact same problem with me Debora5676

updated my iPhone 4S 16GB to iOS 6 the day it came out (19th of September) and i've noticed this change ever since.

I also live in an area where there is no cellular reception and therefore when i get home, i turn my phone to Airplane mode to save battery but leave the wifi on as i can get push notifications like iMessage, facetime and whatsapp.

Now though, after upgrading to iOS 6. When my phone is locked, it disconnects  the WiFi and when i manually unlock it, takes a couple of seconds before the WiFi icon re-appears and i get all my notifications/messages etc.

Extremely annoying.

I can confirm that if you leave the phone plugged in to a power source, the WiFi will not turn off.

I am yet to try the Auto-proxy setting, but if anyone has any solutions, it would be greatly appreciated!

Hi, I will go to Apple store and I hope to resolve, because with ios 5.1.1 I haven't this problem

would be good if you can take a print out of this thead with you to show to them the detail of the problem and the fact that it isn't just you experiencing it!

It's a good idea. I don't think that is normal that wifi don't work in standby, because with 5.1.1 it worked. And is absurd that I can't receve notifications of iMessage and whats'app when iPhone is in screen lock. And I saw that, when I turn on the screen, often it don't find my home wifi network, so it consume much battery, maybe it search network constantly. I hope really to resolve

Hi Alicia, about the new iPhone ...the wifi icon disappear when telephone is in standby, and it reappear when you turn on the screen?

I have exact same problem with my 4S 5.1.1. Wifi turns off some time after phone goes to sleep mode. When I click on Home/LockButton(without even slide to unlock) it itakes couple of seconds to reconnect to my Wifi. It looks like some wifi connection timeout((definately more than a min), because it doesn't turn off immediately after I put the phone is sleep mode. Once connected it stays Wifi connected for a while. If I keep getting notifications frequenly, my wifi keeps connected. Is there a setting somewhere on iPhone how long the wifi keep connected when phone goes sleep ?? Is it a setting on Wifi Router ? Didn't get a right answer yet !!

Hi, I went to apple store today and they replacement my iPhone 4S with another iPhone 4S that have ios 5.1.1. I see that in this new iPhone wifi icon disappear when it is in standby, but I receve notifications. In my old iPhone 4S wifi icon not disappear when telephone is in standby, the new iPhone yes, but important is that I receve notifications. Now I try to download ios 6, I hope that there arent't problem
