Diversity offers some comfort
What can you do if multipath is causing problems? Aside from clearing desks 
and chairs from your building, diversity seems to be the best solution to 
combat the perils of multipath. Diversity is the use of two antennas for 
each radio in order to increase the odds of receiving a better signal on 
either of the antennas.

Diversity antennas have physical separation from the radio to ensure that 
one of the antennas will encounter less multipath propagation affects than 
the other. In other words, the composite signal that one antenna receives 
may be closer to the original than what's found at the other antenna. The 
receiver uses signal-filtering and decision-making software to choose the 
best signal for demodulation. In fact the reverse is also true: the 
transmitter will then choose the best antenna for transmitting in the 
opposite direction.

If diversity doesn't solve a severe multipath problem, then consider 
deploying an 802.11a network. You'll also gain the benefits of higher 
performance and freedom from RF interference, but of course you'll need to 
consider interoperability issues and possibly higher costs.
