Hi, Dave,
	Have you confirmed the signal condition from your basement?  The WLAN
signal is very multipath capable, and the receivers for good systems can
pick it out of the mud with only about a 1db SNR.  That is about 10
times as sensitive as most Ham Radios, and about 10000 times more
sensitive than most AM or FM table radios.

	The technology is really amazing.
