Here is how I do it - as root I issue:

iwlist eth1 scan

This is assuming that eth1 is your wireless interface, and that the
accesspoint actually broadcasts it's name. If you have a different device,
replace eth1 with your wireless interface.

When you issue this command, you will then get a listing of the wireless
sites that exist in your neighborhood.

To connect, you will have to set a few parameters:

iwconfig eth1 essid "ChoiceOfEssID" key "keyIfNotOpen"

After setting this, I just issue:

dhcpcd eth1

to get an IP address.

good luck, -borries.
