I have recently installed DWL-G520 (rev B), Atheros based wireless LAN card on FEDORA CORE 3.i have installed the MADWIFI drivers for it. Now the problem is that whenever i try to activate the card with ifup ath0 command it gives the following error message.


Error for wireless request "Set Encode" (8B2A) :
SET failed on device ath0 ; Invalid argument.

Determining IP information for ath0... failed.



Can anyone help me out of it? I have tried static ip settings but that also to does not seem to work. Please guide me how to proceed? My confgurations are as follows since i want to work in Adhoc Mode.

My configuration file is /etc/sysconfig/network-scripts/ifath0 and its contents are:

ONBOOT=yes
DEVICE=ath0
BOOTPROTO=yes
WIRELESS=yes
MODE=Ad-hoc
ESSID=fahad
CHANNEL=7


Waiting for someone to HELP?

Hello Fahad,

You have plenty going on wrong in that lot.
/etc/sysconfig/network-scripts/ifath0
should probably be:
/etc/sysconfig/network-scripts/if-ath0
As for the contents of the script itself, if you are in ad-hoc mode then you must set your own IP address as you do not have a DHCP server to get an IP address from. You might also want to change your channel to 1,6 or 11 as these work the best with least interference in my experience. Check and make sure your card can see the nework with
iwlist ath0 scanning
although your interface may not support it.
Regards
Chris
