I'm sure the temperature can vary quite a bit in my attic. But even during cloudy cool days when the temperature is pretty constant, I still seem to experience the problem.

Here in Louisiana it can get very hot in the summer. I have measured the attic temperature at as much as 110º F which is slightly beyond the environmental specs of the rest of my network equipment (1 router, 1 switch, 1 dsl modem) but they have all worked well for me despite this. The WAP 11 has not yet been exposed to such torture, but perhaps the temperature changes on some of the sunnier fall and winter days are disturbing it, as there is no temperature control in the attic at all.

I recall running the unit indoors and still experiencing the same problem with throughput, but perhaps I am mistaken. If the problem returns, I'll try relocating. So far it's been 16 hours since the firmware upgrade and all is well.

Thanks for the suggestions.
