Comment (by [EMAIL PROTECTED]):
I can also confirm this problem with the AR5005G (AR2413) with madwifi-ng
0.9.2.1 and the 24-2-2007 snapshot using Gentoo, and so do some other
people on Gentoo as well.
When sitting in line of sight of the AP it loses signal after not so long.
When using WinXp in the exact same spot the signal strength is excellent
and not losing the connection.
I do have to say that when I set my router (D-Link DI-524) to operate 802
.11g-only and set the TX-rate to 54 mb/s-only in the router the connection
does not drop out anymore, but the signal remains weak according to
NetworkManager, +/- 28% at 3m open space direct line of sight. At the same
time however the Gnome Network Monitor reports 72%, so I guess the signal
is relatively fine, but NetworkManager just reports a lower number due to
the different calculation.

My thinking is that it has something to do with switching modes. Since I'm
not really into this stuff I don't know how to find out either.
