We see packet loss problems at about 15 STAs and 200pps, but probably
because of contention/interference. I have not tested with hardware
(Orinoco or other) AP, so don't know how they will perform in the same
environment. However I believe that this is not problem of hostap driver
itself but 802.11b problem.

At the time we begin to see packet loss the hostap underlayng OS shows:

23:28:17 up 11 days,  1:32,  1 user,  load average: 0.40, 0.37, 0.37

This system have 2 Senao CD-2511+ EXT2 (23dBm) cards and is 486 DX/4 at
100MHz. In the indoor environment it was able to forward almost 5Mbps
between 2 STAs. We are still using version 2002-10-12.
