Installing usb wireless card on Debian Lenny

1/ CNet CWD-854 Dongle, P/N: 18-1HGWD85CH.
- Install the packages kernel-headers, wireless-tools.
- Go to http://rt2x00.serialmonkey.com/wiki/index.php/Downloads and download the file rt73-cvs-daily.tar.gz.
- May need to blacklist the RT73 driver available to the distro (?):
echo "blacklist rt73usb" >> /etc/modprobe.d/blacklist
- Extract rt73-cvs-daily.tar.gz, go to its Module/ directory, run make and make install.
- Run vi /etc/modules and at the end of the file, add rt73 in a new line.
- ls /etc/modprobe.d/ | grep rt73 to check if rt73 file exists, if not, touch rt73 and echo "alias rausb0 rt73" >> /etc/modprobe.d/rt73
- rm /etc/modprobe.conf as it is not necessary.
- run iwconfig to check the recognized name of the device.
- create a script called wlanz, for example:

#!/bin/sh
ifconfig wlan0 down
ifconfig wlan0 up
iwconfig wlan0 mode Managed
iwconfig wlan0 key XXXX-XXXX-XX
iwconfig wlan0 essid "My ESSID"
dhclient wlan0

chmod +x; then run it.
See Module/iwpriv_usage.txt in the driver package for information on other types of encryption and settings.
The above settings can be put in /etc/network/interfaces (restart the interfaces: /etc/init.d/networking restart):

auto wlan0
iface wlan0 inet dhcp
        ifconfig wlan0 down
        ifconfig wlan0 up
        iwconfig wlan0 mode Managed
        iwconfig wlan0 key XXXX-XXXX-XX
        iwconfig wlan0 essid "My ESSID"

To list available networks: iwlist wlan0 scanning.

2/ Linksys WUSB54G:
- similar to the above
- using rt2570 chipset
- the interface named rausb0

Note: D-Link DWL-G122: rev B - chipset rt2570; rev C - chipset rt73.
