Q: IOS6 unable to download apps from app store

Your description of the problem isn't specific enough to diagnose an issue... it can be one of many things from the connection you're on to the settings on your phone.

Try connecting through wifi.  Apps bigger than a certain size cannot DL through the cellular network.

Also, "please help" for a free game?  Is it really that big of an emergency right now? lol

Nooo... don't turn that off.  Try disconnecting from wifi (turn it off in settings)... see if you have the same issue.  Anothing thing you can do if this doesnt work is reset your network settings through General --> Reset --> Reset Network Settings.

I am having a similar issue.  It isn't just installing applications, it is also just using the wifi.   I tried the Reset Network Settings.  That didn't work. 

I figured out my issues.  I went to the Apple Store and used their wifi.  It worked fine. 

Then I came home and it still didn't work.  The symptoms are that wifi would work for 20 to 60 seconds and then turn off.  In other words I could get the some of a You Tube movie or app download, but then it would stop. 

I launched AirPort Utility and there were two firmware updates for my Time Capsule.  I have the 1st generation time capsule from 2008.  After applying the firmware updates it has fixed my issue.

I've been running 7.6.1 firmware on my extremes for a long time now. That's not the fix (for me, anyway..)

I am having trouble with my wifi downloading music and any app from the stores.  Sometimes it will download just fine, other times it will error out or say it cant connect.  So I have to disable wifi and download over 3g.  Anyone have any idea?

The same For me, I sue a iPhone 5 with iOS 6.0.1 and it stop to download app from Apple store onley when I am conected in WiFi. 

i have the same problem. I have an iphone 4 and since i updated to IOS 6 i cannot donlaod any application throgh wifi or 3G form the store i the device. i  also recently updated to 6.0.1 ot see  if taht might help nothing.. i have reseted and turned on-off  wifi and 3g numerous times but stil nada. I can downloda , watch, etc everything else through the web. i have aslo seetd the http to auto in the wfif seting tah soem peolle around teh web suggested... Any more ideas?

I solved the problem, we need to go into iTunes on the iPhone and under the card another - download, check if there are pending download, would solve or delete them. then thendownload from the AppStore under wifi will restaurant to work.

Try and tell me, For me it works.
