[Madwifi-users] ifconfig ath0 up - Segmentation fault

[Shrenik B. <shr...@in...>]

Hello,

No wifi network as yet. Testing things without a network. Is it possible to do so or should I wait till I have my wifi router set up and then try.

Running mandrake 10.1; kernel 2.6.8.1-12mdksmp (pls note that it is a smp kernel) on my laptop. Could there be a problem due to the smp kernel? 
Compiled the current build of madwifi for 10/09/2005 with a make; make install;

Harddrake -hardware tool from Mandrake shows the following for the wifi
card:
