Ok, then if 192.168.1.10 is the desktop, and the above is what the
desktop sees, and you see that over and over again it means there's a
communication failure between 1.1 and 1.10.
Try running tcpdump on 1.1 at the same time. Does it see these ARP
requests? I'm guessing not.

My bets are on the 'ra0' driver or hardware. :) Never underestimate
how absolutely crap 802.11 hardware/firmware and drivers can be..
When the problem occurs, does iwspy/iwconfig/iwlist whatever it is
tell you that it still sees the AP, still happy with the link, etc.
(I can't remember what you do with the linux wireless commands
unfortunately - maybe someone else does).
