Linksys WET11 Connection Issue

My laptop is connected to my Linksys WET11 via a WPC11 wireless card. I can connect to my network ok. I log into my NT domain.

My problem is that I cannot get outside of my router to another subnet or the internet. The only thhings that I can seeor ping are those things that are on ther same subnet as my laptop and the WET11.

The WET11 has the ability to be set up in Ad Hoc mode or Infrastructure mode. I have it set up in Ad Hoc mode because that is the only mode that works. I am wondering if I have the configuration incorrect.

Linksys has been no help whatsoever.
