wireless card

My wireless card got unistalled and I don't have the disc or key. Is there anything I can do to fix this problem? thanks a bunch

 

Go to the card's manufacturer's site and check the support pages. You should be able to download the drivers and reinstall them.
Make sure you have the correct model and version number of your card.

 

if you mean the security (WEP / WPA) key - connect via an ethernet cable and do an ipconfig to find your gateway address (modem/router's ip) and enter it into your browser or just search your wifi modems model to find out how to obtain/change the key
