Hello,
I'm using last madwifi trunk version on a fresh new Zepto Z-Pro card,
AR5418.
WEP and WPA connections works fine. But on heavy downloads/uploads, taking
all bandwith (aprox 1Mb/s), the wifi connection freeze. I Wait about 1 to
5 minutes, and it goes up again.
Here is my config

Is there any other thing i can test do be more precise?
I use "wicd" to managed networks, but gnome-network-manager works
identically.
Using "iwpriv ath0 bgscan 0", doesn't change anything .
I wonder why there is about 100 packets input/s at anytime, when ath0 is
up (associated or not)? Is it normal ? Network Monitor report 10K/s...
This is visible on my athstats.
