Anyway, I have noted big discrepancy between athstats rssis.
Athstats claims "rssi of last ack: 50" and "rssi of last rcv: 29".
But iwconfig "Signal level=-65 dBm" (95-65 = 30).
  Before a problem occured both rssi are a same. See below.
May be that could help to localise a problem.
  Wrong noise level handling?


Of course I agree that a best way should be to get madwifi-ng to be stable
enough to fully replace madwifi-0.9.4.
