So I've set up a new 1 TB TC as the main router for my small home network. I have it hooked up to a Comcast cable modem and a direct ethernet line to my 24" iMac. Works great, I'm using DHCP and there are no problems. My wireless network is an 802.11n (b/g compatible) and I have a MBP and an Apple iPhone with WPA2 security. When all is set up everything works perfectly, but after about 1 hour the wireless network stops broadcasting and it won't reappear unless I reset the TC using Airport Utility or if I unplug and replug the TC. I've tried changing the Wifi broadcast channel from automatic to a set channel, dropping all the passwords for the TC from my keychain, etc to no avail. The ethernet connection continues to work just fine When it works it works great, but then the Wifi disappears! I've searched all the TC and wireless posts, but have not found an answer! Time to visit the local Apple store?
