Hello,
I've got a problem with my WIFI connection using Madwifi :
When I'm under Linux, I can activate my connection with :
#ifconfig ath0 up
#iwconfig ath0 essid myAP
#iwcomfig ath0 key my:wep:64:bits:key
#dhclient ath0
And it usually works but I recieve a very large ammount of "rx invalids
nwid" packets, and so my connection is always unstable and very slow.
At the beginnin I thought that the problem was the distance between me
and the a.p. , but then I tryed to connect under windows (with the
default connection manager), and it works perfectly.
Does anyone know what could be the problem ?
Thanks a lot

Hello,
Here are some new informations I got ... If somebody can find what's wrong, it'd help me very much. I compare my params under windows (where the connection works very well) with the params under arch(where the connection is unstable)
