The diag LED is supposed to go off after a minute or so after boot, but it doesn't. The entire device is unaccessible. It happens when I boot it with nothing plugged in, and also when the WAN is connected to the main router (the buffalo is supposed to bridge) and it also happens when I connect it from LAN1-4 to laptop or PC.
So no matter how I connect, it never stops DIAG.
The reset button seems unresponsive too. I tried pressing it for 3sec, 10sec, right after boot and before boot. Doesn't do a thing ;(
Any ideas?
