Hi.
I use the pcmcia version of that card. There are issues with particular firmware versions and Linux which I imagine might cause the problems you're seeing. Try searching on the kismet forums (
www.kismetwireless.net) for 'cisco' and 'firmware' to find out what the right version is, then flash the card (this is probably easiest done from Windows, unfortunately). As I said I use the pcmcia version, so this *might* not apply.
As for the LEDs, normal operation (in Managed mode) is flashing steady green, and a flashing, sort of vibrating orange (probably what you're describing). While the card's being initialised the green light stays on (as does the orange one, if I remember correctly). In rfmon mode (wardriving mode), the green light flashes, and the orange light only comes on when the card picks up traffic. Again, this is for the cardbus card.
You might want to install Fedora with the card out, then plug it in later, and tell kudzu to ignore the new hardware. If you're wardriving, you'll have to use iwconfig to put the card into rfmon mode anyway, so it's probably not a good idea to let kudzu try to set it up for you. You can insert the driver using modprobe yourself.
Hope that made sense.
Dave
P.S. I've got a couple of scripts which configure my machine for wardriving which might make your life a bit easier...
