Not really - some of the older NICs/firmware do not use it.

What is the model of your wireless card?

Dreamquick is correct - sometimes WinXP will try to bind your ethernet and wireless together. You can go to "My Network Places" on the desktop and right-click->choose "properties" and right-click on your ethernet connection and choose disable.

Updating the firmware on the adapter is always a good thing - just don't upgrade your access point firmware on many of the Dlinks unless you are connected via ethernet...
