Make sure the wireless security settings are matched exactly at both 
ends.  (WEP, WPA Personal, WPA Enterprise etc.),  Next make sure the 
same encryption standards are chosen at both ends (3DES, AES, Blowfish 
etc.).  Make sure you are entering  the passphrase in the right field - 
sometimes there are key fields for keys 1 through 4 - in which the 
passphrase will not work, but a key generated from the passphrase will.  
Make sure if it is key fields, the same one is referenced at both ends.

If your computer is seeing the ESSID broadcast from the router under 
Linux, then is is most likely one of the above.

Once things are working you might want to consider turning off broadcast 
of your ESSID at the router, it just makes random hackers work a little 
harder on you versus your neighbors.  Don't be the low hanging fruit if 
you can help it.
