Problem WiFi while iPhone 4S is in screen lock

I bought an iPhone last week, and I've realized that when the iPhone screen is locked wifi disconnects.

If I have also connected 3G, the 3G connection appears, and if I have not connected 3G is none connection.


And in milliseconds reappears wifi icon again.



Is it normal?


Thank you very much.



*I heard something about it, but it happened in old iPhones.

iPhone 4S, iOS 6

Ok i came up with this solution. It seems working for me. So try this out may be it ll work for you too. First consider the router you are trying to get Wi-Fi connection also serves other I-Phones in the same time. Now, Go to Settings>Generel>About>Name and change the factory released (I-Phone) name to your own unique name. Then go to Settings>Wi-Fi and hit the "OFF" button for "Ask the Join Networks" and switch it to "ON". Later go Safari and try to load a webpage. I-Phone automatically will pop a window showing you available networks. Choose your Wi-Fi spot and enter password. Let I-Phone see and recognize your Wi-Fi spot. Reboot your device. I-Phone will restart with Wi-Fi icon on meaning connecting to your Wi-Fi network. You can now turn off "Ask Join Networks" if you want.

Hope that will work for you. Reply if it works for you. Thanks

My friend thanks a lot for your help but after doing the steps you mentioned was the problem of wifi off when screen locked solved??

I tried your solution it showed wifi connected after reboot only when PASSCODED WERENT SET ELSE IF PASSCODE WAS THERE IT WOULD CONNECT UNLESS WE UNLOCK WITH THE PASSCODE.

SO FRIENDS IF YOU WANT MR.JASON's solution you should keep PASSCODED OFF

Lots are saying this is expected behaviour with iPhones, they have a mobile/cellular network connection to fall back on, but what if you're on an iPod or wifi-only iPad?


My iPod has just started doing this since updating to the latest version of iOS6 - no messages come through if the screen has gone off, I have to unlock it to check. Useless. So much for "it just works".

I think iOS 6 has the problem this was not the case in iOS 5 so according to me to turn wifi on even when your phone is in sleep is to let the safari browser running in the background yes it could use your battery a little but I think it is the only option available it worked for me


Actually, NO. iOS 1 had this FEATURE. iOS 2 had this feature. iOS 3 had this feature. iOS 4 had this feature. iOS 5 had this feature. iOS 6 had this feature. And its likely that iOS 7 will have this feature. You can confirm this by doing a search of the forum going back 7 years. You will see mention of it for every version since the beginning.


Its there because WiFi, when it is on, requires a continuous 30 mw of power, unlike cellular, which only uses power when sending or receiving. If WiFi stayed on all the time it would drain the battery in a few hours. Then you would see complaints about the battery draining fast, rather than WiFi turning off when the phone goes to sleep.


It is BY DESIGN this way. If you want to keep WiFi on when the phone is asleep just plug the phone into its power adapter. This overrides the automatic shutoff.
