On one link, approx. 3 km distance, I got no link with both sides FreeBSD, athstats reported rssi 6 when one side was changed to Linux with madwifi, and rssi 23 when both sides were Linux. I was forced to use Linux on all radio links due this. I would like to repeat this test indoor, but did not have time yet. This drives me crazy because I am forced to use system I don't like :( Milan -- No need to mail me directly. Just reply to mailing list, please.
