Wireless card options for Dimension L800CXE ?

What are my best options and/or restrictions for installing a wireless card on a Dimension L800CXE - running XP Home, wireless Belkin Pre-N router?   Any compatability issues?

 

Here is the whole scenario...

 

Environment:

- Inspiron notebook using a Dell Pro 2200 wireless card, via a wireless network is connected to a  Belkin Pre-N, which is connected to a cable modem.  Working fine.

- Dimension L800cxe is hardwired to the Belkin.  Working fine.

 

Goal:

- Want to be able to print to a Dell 962 printer from the L800 and the Inspiron (wireless) laptop.

 

Problem:

- Trying to connect the printer to the L800 along with a Dell 3300 wireless printer adaptor (so that the Inspiron can print from it.)

- Resolved: Had to upgraded the L800 from Win/ME to XP Home, as the 3300 wouldn't work on ME.

- Open: Running the 3300 set up procedure on the L800 won't recognize the wireless network. (The L800 is hardwired to the Belkin) 

 

Fix?

- I'm guessing now that I need a wireless card on the L800 -- even though then I bought the 962 and 3300 and explained my goal, Dell told me that wasn't necessary.  Seems like it is.   Is this the cure and what card restrictions do I need to be aware of?

 

Thanks for any advice.
