The problem occurs with my older G5 as well as my new iMac 27". I can't use my wireless connection to transfer large number of movies to my Apple TV, the wireless service goes down. I had to resort to using an ethernet connection to do the job. Syncing a single movie is OK though.
This must be a recurring issue. Why some people have problems and others don't, who knows, but it is frustrating to say the least.
Same here with the predecessor model (Airport Extrem simultaneous dual-band). It needs to be constantly rebooted if I do massive file transfers or downloads.
Sometimes there also seems to be a protocol issue, because the computers stop being able to successfully connect to the WiFi network, even though they can see the signal. Only rebooting the computer works.
So I think we have a variety of issues here: driver/demon issues on the Mac side (they crash or get confused by something, possibly out of spec responses from the base), and either base stations that over heat and/or have buggy software.
If you're in an air conditioned environment and only use the device for casual web browsing and backing up a few changed documents, then it works well. If you work with large files and have tens of GB that are being transferred on a semi-regular basis, you're in a world of pain.
Unfortunately, I have yet to find ANY WiFi product that "just works". They all have thermal management issues, underpowered hardware, and buggy software. I think eventually it may be cheaper to get a NetBook and run something like pfSense on it as a dedicated software base station with way more capabilities and backup power (laptop battery), than to deal with all the hassles of the various WiFi base stations. Too bad, because the ease of management for a simple network is great in the AirPort product line.
