I have an Airport Extreme, this was just replaced with a new one because my old one did the same. I also trouble shot my ISP and just installed FIOS. I have an Imac G5 connected wirelessly upstairs with full signal. I have an Xbox 360 connected to my airport via Ethernet cable. When I am playing online with my Xbox 360 my Airport will reboot and I will loose my Xbox live connection. I changed the Ethernet cable with a new one, still didn't help. I am at my wits end I cant figure out how to fix this problem. Could it be the XBOX? When I watch movies on my Xbox and stream them wirelessly from my computer I never seem to have a problem with it rebooting. I just dont know this is making me insane. I will be racking up kills on Call of Duty 4 and then my airport resets and I loose all my kills. SUX please help!!!
