I'm having issues with one last remaining issue with my 100mW NL2011CD PLUS EXT2 card (basically the EnGenius/Senao/Intersil one). I can't get it to "work" for getting online, however it does work fine with "kismet" and also "wavemon". I've searched google and found a few other references to this, but no solution was posted. Anyone have ideas? This is with RedHat 9 (shrike) from fresh install. [root@xxxxxxx X11]# ifup wlan0 Error for wireless request "Set ESSID" (8B1A) : SET failed on device wlan0 ; Invalid argument.
