I posted last week wondering which of my devices (TC, iMac (running 10.5.2), Apple TV) was malfunctioning and now I'm pretty sure it's Time Capsule running in 5 Ghz 802.11n. My Apple TV cannot keep the signal-- it drops it daily--which means I have to retype the password every single time (which those of you with long passwords on your Apple TV know is reaaaally annoying). When transferring files (be it to the Apple TV or to the TC hard drive) it consistently drops the signal and makes me restart the file transfer. A couple of notes: 1) I have an Airport Express running in bridge mode and when I switch to use that network (802.11g), I've had no trouble syncing anything to my Apple TV. 2) I usually can get around 1 GB transferred without a problem, but anything over that I get the dropouts. 3) If I'm browsing the web it seems as if the file transfers do better--still not great--but better. (This might be a spurious relationship, though--I have no idea if keeping the TC connection active really would make the transfer run better). 4) I couldn't get the initial Time Machine back up to wirelessly back up (around 60 GB), but after transferring using ethernet, I've not had any problems with subsequent back ups--but they've all been well under 1 GB. 5) I've not been able to sync a movie to my Apple TV while using the N network. The signal is dropped every single time. I'm about ready to call Apple and see what they say, but wanted to check here first and see if anyone had any suggestions about things to try, settings to change, etc. Or if anyone had any general opinions or insights into the problem. Thanks!
