Query: If it works, it works great

I set up a network of 4 pcs with the Linksys router. Of the three of these cards I've tried, only one works. The one that works, works great and couldn't have been simpler to install. I returned the defective one and got another defective one in replacement. I called Linksys tech support - tech said I just had bad luck in getting two bad cards - maybe I got an older version of the same model number....not a great response.
