Mailed this to madwifi list but haven't got any response. Trying my luck here in case somebody with wireless knowledge can comment on this problem.

I am using madwifi driver for D-link DWL-G520 pci wireless card. The
card is working in access point mode (master mode) and has WPA-PSK
encryption enabled using hostapd. I am also running a DHCP server on
this machine (which has Debian Etch and 2.6.17 kernel) and the card is
working and gives out ip addresses to wireless clients.

However, if I do ifconfig, I see that there are frame and TX errors. I
wonder why these are there and if I am doing something wrong or if I am
missing something.
#> ifconfig  ath0
ath0      Link encap:Ethernet  HWaddr <hex addr here>
           inet addr:192.168.5.1  Bcast:192.168.5.255  Mask:255.255.255.0

#> ifconfig  wifi0
wifi0     Link encap:UNSPEC  HWaddr <hex addr here>
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:61091 errors:0 dropped:0 overruns:0 frame:9156346

           Interrupt:201 Memory:c8bc0000-c8bd0000


The TX errors and the frame numbers in wifi0 is what I don't understand.
Can anybody explain these?

Also, why is the MTU of ath0 2290 and not 1500? Is this something that
is normal in wireless interfaces?

Thanks,
->HS
