That is really strange as my iPad 2 will not connect with my router on channel 1.?
My router is a Netgear WNDR 37AV v2, which is no more than a rebranded WNDR3700.
My HP wireless printer and Toshiba Laptop will work on channel 1, but not the iPad.
I set my router to a different channel and everything works fine.
While trying to move away from the channel that my neighbor is using, I set the router to channel 1.
After many tries, I found that my iPhone 4S will connect and run on any other channel except 1.
I've set it to "up to 150" and "up to 300", but nothing helps.
The iPhone shows a good connection to the router, but it won't connect to the internet on channel 1.
