Just adding my voice to the Chorus. I've posted this as a standalone question but am copying it here to be part of the critical mass.

I'm helping a friend who is having wifi problems with a new ipad4 (the one with the new dock connector).
I have an ipad1 (32GB, AT&T) and it works fine on his network
His wife has an ipad2 (Verizon) and it works fine on his network
He has a new ipad4 (32GB Verizon, the one with the new connector)
PROBLEM: The ipad4 is very slow to update mail (wheel will continue spinning after the other ipads have completed) and fequently can't load web pages from safari even though the other ipads connect. Interestingly, Pandora streams music from the ipad4 to the airport without interruption.
Network details: Fios service with an actiontec router which creates a wifi network. This router is at the far end of the house, and in the basement (so far away it frequently doesn't show as an available network). Much of his network traffic is ethernet
Because of the distance to the Actionec router we have an airport express connected via ethernet which creates a wireless network (b/g/n compatible as he has an older laptop which doesn't support N). Different wireless name and security.
Airport express is about 5 feet off the floor. Sitting 8' away from the Airport, and in the same room, the Ipad1 and ipad2 work fine. But the ipad4 will experience the problems I described above when the other ipads (and the laptop) work well.
What we've done:
He has already had apple replace the ipad4 once. This one is fresh out of the box and with the same problems as the first unit had.
We swapped out the Airport with one of mine to see if that was the problem, but nothing changed.
I know that he is competing with a lot of neighboring wifi networks. At my home, two floors down from my airport express I get 4 bars on my ipad1. In the same room as his Airport I get 2. We're working on figuring out sources of interference (cordless phones, no alarm system, etc), but baffled as to why the ipad4 is having problems the other ipads aren't having. Changing channels on the airport doesn't seem to have had any effect one way or another
Any thoughts?
