Yea, for it to act as a repeater you need to use some of the hidden options, so there is no documentation for it, and very little even feed back. Thats because few have two 4500's, and even fewer still no its possible. Eitherway it's alot of work for 1 Ipad. Still not sure why the wireless radio just can't roam. sure, you will get a pause as it shifts, require the session, and rebuffer, but it shouldn't take more then 3 seconds. I know because I have a friend with a iphone with the skype app and he can walk down the street, and the phone will pick up new open networks as he goes along. Its different traffic though so..hmm. either way, let us know how it goes.
