Is that the card you are currently trying to use, or is it a different one? A
couple of things you will want to check: ensure that the driver for the card you
are using is properly loaded, whether as a module or in the kernel. If the
driver is present, make sure that it is properly recognizing the card, and
assigning it to a device, such as Wlan0. One way to check for this is to run
dmesg | grep -i wlan and see what if anything comes back as a result. The other
thing to check would be actual Netlink support in your kernel, but the former is
currently far more likely.
