I have a AP340 which hangs after a period of time. No response on the console. The Status LED stays lit solid. The Ethernet and Radio LEDs are off. Once, I saw a Machine Check Error and it rebooted by itself. Version is 11.21.
If you can, keep a workstation consoled or telnetted (over the Eth connection)into the unit until it hangs again. If you keep getting errors like that, you've likely got a bad unit.
