Apple TV 2 and AT&T UVerse issues
Here's the basic issue: AppleTV has no problem connecting to the WLAN, recognizing available home sharing libraries, etc. When streaming anything that's not local however (i.e., Netflix), the stream stops repeatedly. During a 90 minute movie, the stream was interrupted at least 25 times. Twice, the router seemed to kick all wireless devices off the network momentarily.
I can plug the ATV into the UVerse cable box via Ethernet cable, and the streaming issues are more or less eliminated, but this solution doesn't really work for us, because it makes it impossible to stream any local media (ATV no longer sees any local libraries or devices) or to use the Remote app to control the ATV, since the two devices cannot see each other on the network.
HARDWARE:
Router/Modem: 2Wire 3801HGV with default settings, save for some minor port forwarding for unrelated applications
Apple TV 2
Main media library host: 27" iMac i7, connected wirelessly
iPhone 4, which we'd like to be able to use to push media and use as a primary remote control for the ATV
There are several other Macs, iDevices, a PC and a PS3 all connected wirelessly, if that's at all relevant (we average 8-10 wireless connections at any time).
Optimally, I'd love to be able to run the ATV as intended: with full access to all iTunes libraries and iDevices on the WLAN. It's immaterial to me if this is achieved with the ATV plugged into the AT&T cable box or wirelessly. As it stands right now, however, the wireless setup performs terribly.
It seems as though any advanced networking with the UVerse setup can be quite difficult, but I am willing and able to attempt any known fixes for this issue.
Thanks so much in advance; I really do appreciate your help.
