I have been running a Airport Extreme in bridge mode with a Telus Actiontec modem hardwired. The extreme is approx 6 months old and for the first 3 months appeared to be running flawlessly. Three months ago I started having problems with losing internet intermittently. Being that it was my internet connection; I contacted my Isp; which is Telus. After 6 visits by 6 different technicians; it appears that the problem was solved. (installed a new modem and upgraded the firmware. Old firmware had a bug; as it appears that the telus modem and Mac computers, didn't work nice together!) The problem I started to have about two months ago; is that, I can't get the Extreme to work properly; as I occasionally lose the signal. At the very least once a day. If I go into the wireless Utility after the signal is lost, I get a error message stating that "No configured Airport base station has been found"! My solution is to bypass the Extreme and connect wirelessly to the Telus modem; or reboot the Extreme; and it will work till the next incident. I must explain why I knew that my first problem mentioned above with losing my internet was a Telus problem. I have Optic Tv through Telus. It is a service supplied through the internet. The Optic boxes are wired directly to the Telus modem. Therefore if the internet drops of; even for a second; all the boxes go black. Now that I have a new modem with the proper firmware; this doesn't happen anymore. I was hoping that after the Telus fix; that would be the end of the problems with the Extreme. Not!!! Any thoughts on this?? Might be time to take the Extreme back to Apple; as it is still under warranty.
