had that one. What a mistake, atleast for me. I suffered with it for 8 months. I bought a new Airport Extreme in late december, hasn't had to be reset yet.
One data point does not a trend make, but I've had my Airport Extreme since March 1, 2008 and it's running fine. The biggest reason I have for using an Airport Extreme is that, even though it's not officially supported, you CAN hook up an external drive to the USB port and wirelessly backup to it from a Macbook using Time Machine.
