Some notes for working with Wi-Fi on Linux:

View available wireless networks:
sudo iwlist eth1 scanning

Bind to a network (request ip address):
sudo dhclient

Check connection status:
sudo iwconfig

Disable wireless:
sudo ifdown eth1

Setup Kismet:
edit /etc/kismet/kismet.conf and change source= to
source=ipw2100,eth1,mycard
sourcetype is one of the sources listed in /usr/share/doc/kismet/README.gz; mine happens to be the nickname given by iwconfig. You may also need to set suiduser= to your login.

I have an old Hawking Tech HWU54G Mini Wireless-G USB Adapter which runs a ZyDAS ZD1211 802.11b/g USB-WLAN-Chip. There’s a Linux driver at:
