Are you running the Dell Wireless Utility? Try stopping that service (go into Services, find the Dell program on the list, and Stop it, and then change the startup type to Manual) and start the Wireless Zero service (and change the startup type to Automatic).
When the Wireless Zero service is running, open your wireless networks list and see if you can see any networks (assuming there are some nearby to find). If you get a message that says something like "Wireless Zero is not configured to manage your network connections," go into the Advanced properties and put a check next to the box that says "Allow Wireless Zero to manage my wireless networks").
If you still can't see any wireless networks when there are some around, then maybe you do have a damaged antenna. It's probably not worth spending the money for parts and labor to have it repaired or replaced, especially if your computer is five years old.
Remove the card and use system restore in accesories to see if you can restore to a time previous to installing the card.
If the problem persists, you can run dxdiag, go to start>run, then type dxdiag and hit enter, go to the audio tab and it will point to the problem
