Assuming that you do not have WPA (your iwconfig seems to indicate that you are running bcm43xx) The fastest way to do this, is to do the following:

iwconfig eth1 essid "<your_ssid>"

iwconfig eth1 key "<your_wep_key>" (if you have a WEP key)

dhclient eth1

If you still can't get connected, you may want to check to see if your firmware is right, there is a wiki article about this here:

https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx/Edgy

It references a recommended firmware, I would recommend that you use it. If you have, you may also want to try to get a different firmware from another supported driver (http://bcm43xx.berlios.de). However, I find that the driver recommended on the wiki works with my laptop better than any other thus far.

Once you get this working once, I also recommend using the Gnome Network Manager tool in Ubuntu to manage locations. After I got my card configured, I hardly had to use the command prompt anymore.

You need to be root to do anything to your wireless interface.

Add sudo in front of the commands in the prior message.

I have the same problem, I can't connect my wireless card, I have a nick with a passwd, so I need put the nickname and pass like in wondows, but if I put the passwd that's the result:

root@Antares:/home/jansarz# iwconfig eth1 essid "RIU"
root@Antares:/home/jansarz# iwconfig eth1 nickname "jansarz"
root@Antares:/home/jansarz# iwconfig eth1 key "YQWHsuC"

Error for wireless request "Set Encode" (8B2A) :
    invalid argument "YQWHsuC".
