Tutorial: DLink DWL 122 on Gentoo
I've got the D-Link DWL 122 USB Wireless card, and getting it to work on Linux was a pain, but after I figured out what was going on, I got it to work on gentoo fairly easily. Here's what you need:
-linux-wlan-ng-0.2.1-pre17 (it's not in the distfiles on the LiveCD, so you'll have to get it on your Gentoo Box somehow)
Place the linux-wlan-ng tarball in /usr/portage/distfiles, and run:
Plug in the card
USE="usb -pci" emerge '=linux-wlan-ng-0.2.1-pre17'
and you should be set.
wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
