Other than that I don't have any obvious sources for interference. My wireless phone is old technology (900mHz) and my microwave is not being used at the same time.

As an aside, my Sony 900 MHz (mHz is milliHertz) cordless phone is completely non-functional if I place the cradle/base station beside my 802.11b base station. My guess would be that the 802.11b base station has enough of an RF spur near 1800 MHz to cause crippling interference. (That's curious, though, since you wouldn't expect to see an 1800 MHz spur from a 2400 MHz transmitter, especially if it passes the FCC requirements).


But I can't deny that my cordless phone doesn't work when the phone's base station directly lined up between the handset and 802.11b base station, either.

OTOH, I haven't noticed any significant dip in signal strength for my 802.11b network in these situations.

By the way, if you notice that your wireless network goes down when you use your microwave oven, it's time to buy a new microwave oven. They are supposed to be shielded well enough to not let out any significant amount of RF radiation. High-strength 2400 MHz microwaves are dangerous precisely because they cook food. Don't get near that oven when it's working, especially not if you start to feel warm! ;-)

(Hey, what's wrong with 900 MHz technology? In many ways, a 900 MHz phone is superior to a 2400 MHz phone, despite the marketing. It's got a longer range, better penetration, etc. Did you know that 2400 MHz is near the resonant frequency of the water molecule - that's why microwave ovens use that frequency to cook food, and that's also why 802.11b/g wireless links peter out quickly when the line-of-sight is interrupted by foliage, rain, or snow.)

Peace,
Drew
