Can't properly configure client mode on Tomato router

[Logomachist]

Dear Internet,

     I just installed Tomato firmware on my Buffalo Airstation G54 router.  My goal is to use it in wireless client mode to give wireless Internet access to an old PC that doesn't have a wireless card.  To that end I configured it according the directions at [Wifi-planet.com][1].  But it's not working.

The Tomato "status" is perpetually "Renewing..." and I can't access the Internet (see attached screen grab). You guys think you can tell me what I've done wrong?


Much thanks in advance!
-Robert
