I am not sure if it's a temperature problem but I also have big trouble with by rb800. It hangs completely after 11 in the morning, if I reset the power I loose all wifi cards and only ethernet ports are functioning. In resources I see all r52n and cm9 (uknown device for r52n and AR5212 802.11abg for cm9). I shutdown power wait a few mins and repower. It works fine. After 5mins I loose it again. Everything works after 4 in the evening.. I have changed wifi cards (I bought more since I thought they are the problem) but again problems.

Problem is when it hangs it does not create any support.rif
The other bigger problem is when it hangs a reboot doesn't do anything.. even if I power cycle I loose all wifi cards and then software reboot will not do anything.. All cards are gone even if I see them in resources.
Outside temp here in Athens was 27->29 celcius.
I have seen RB800 reports from 51 to 71 celcius during the day/night.
Makes me wonder what will happen in August with ~40 degrees outside temp.
But is temperature really the problem? Or something else?
