What APs are available
root@om-gta02:~# iwlist eth0 scan
Using WPA and /etc/network/interfaces
Once you have a /etc/wpa_supplicant/wpa_supplicant.conf file, add a line under the eth0 entry in /etc/network/interfaces:
iface eth0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
Save your changes and run:
# ifdown eth0 && ifup eth0
You'll get a lot of messages, like ioctl[SIOCSIWENCODEEXT]: Operation not supported and sed: unrecognized option `--quiet', they appear to be harmless. The "--quiet" error message can be avoided by replacing "sed --quiet" with "sed -n" in /etc/wpa_supplicant/*.sh
Using WEP and /etc/network/interfaces
iface eth0 inet dhcp
wireless-key my_wep_key wireless-essid my_essid
iface eth0 inet dhcp wpa-wep-key0 my_wep_key wpa-key-mgmt NONE wpa-ssid my_essid
Save your changes and run:
# ifdown usb0 && ifup eth0
Manual attempt
Create and edit a suitable /etc/wpa_supplicant/wpa_supplicant.conf
root@om-gta02:~# ifup eth0 root@om-gta02:~# wpa_supplicant -ieth0 -c/etc/wpa_supplicant/wpa_supplicant.conf -B root@om-gta02:~# udhcpc eth0

Success stories
July 23, 2008
wpa_supplicant 0.6.3-r1 works for me with WPA and WPA2 (with PSK) using the config file template on this page. Unlike the comment above, udhcpc is updating /etc/resolver.conf correctly for me (perhaps this is an old problem).
Bringing up wpa_supplicant manually or using "ifup eth0" with the wpa-conf option set in /etc/network/interfaces works for me. If usb0 was already up when running "ifup eth0" you'll end up with 2 default routes which can cause problems. To solve this either take usb0 down first or run "ip route del default dev usb0" to remove the default route to usb0.

I've had repeated success with:
# ifconfig eth0 up # iwconfig eth0 essid any # iwconfig eth0 key '...' # iwconfig eth0 essid '...' # udhcpc eth0 # ifconfig usb0 down; ifconfig usb0 up
Hope that helps someone. This is for WEP.
The following may be helpful in order to scan available networks :
# iwlist eth0 scan
