Assuming that the basic card and driver are working, then the issue might be in the key. If you are working in a terminal using wireless-tools, then the key must have the "s" prefix if it is a text key (password)-----ie you would enter "s:xyz", where "xyz" is the password they gave you. GUI front ends handle this differently.
to check if your wireless is up and running do "ifconfig". Assuming that that shows your wireless (eg wlan0), then do "iwlist wlan0 scan" to see if you can see the access point.
Here's the complete drill for connecting from the terminal. (Assumes that wireless is wlan0):
ifconfig wlan0 up
iwlist wlan0 scan (omit if you already know all the entriews needed for the next step.)
iwconfig wlan0 essid ... channel ... key s:...
Fill in the 1st 2 blanks (...) with what you get from iwlist. 3rd blank is the text passwd
ifconfig (to verify that you have a connection)
