I was having the issue where I'd have to restart my iTunes all the time, and my ATV2 would forget the WIFI network. I ended up switching my WIFI from WEP to WPA, so I could have a complex password I could remember. Now I'm having an issue where I try and start a movie and nothing happens. It starts for a second and hangs. I've tried restarting all devices, unsharing and resharing and nothing seems to work. I'm running both ATV's on a G Network using a WRT54G Linksys. I didn't have anything running that should be bogging the network down. And it has work for at least 1 movie playing. Nothing more than that. Any suggestions or it it time for a new N router? If I go N...What should I get form maximum compatibility. My iTunes server is a i5 windows PC and I do have some G only devices still lying (Wii etc). Thanks!
