I recently have gotten my Linksys Wireless USB Adapter ( v.2.5! prism2 chipset ) to work with Slackware 9.0 and it was fairly easy.. Here's a little tutorial. I'm sure it would probably work the same way with other distributions as well. But keep in mind, this tutorial will only work for the v.2.5 WUSB11 adapter..
Download and install wlanctl-ng from
http://www.linux-wlan.org/
Read the readme.. I can't recall if you actually have to do ./configure and make, make install.. maybe just an install script. Regardless, the only option I had to make sure was to install the usb driver. I did not change any other defaults.
you might wanna reboot now, just for shits and giggles.
now type in: modprobe prism2_usb
if you do not receive any errors, continue on.. if you get errors, seek other resources for help! =)
your power light should be solid and your link light should be blinking if I remember correctly.
now type in:
wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
you should recieve a "success" message. if not, once again, seek other resources for help.
now type in:
ifconfig wlan0 promisc up 192.168.1.10
now if you type in: ifconfig
you should see a wlan0 interface.
w00t! If your running dhcp and no wep on your access point I believe all ya gotta do, is type in: dhcpcd wlan0
fire up kismet, airsnort, ethereal, ettercap, dsniff, aimsniffer, etc. have some fun!
