Difference between various wireless PCI network cards?Follow

Any wifi card will be able to work with any router at a minimum. That being said, there may be reasons to go with the more expensive card. Within certain card families, some manufacturers include range extension and theoretical speed enhancing features in place, which allows compatable cards and routers to communicate with a stronger, potentially faster signal than two mismatched cards and routers might otherwise be capable of.

If you have a D-link router, you should try to go with a D-link wifi card, if for no other reason then they have tested the two units together extensivly.

I'd be able to give you a better answer than that if you want to provide the model number of your router and the makes and models of the cards you are looking at.

Avoid the USB adaptors like the plague. They are cheap, theya re also horrible bottlenecks that will regularily loose signal.
