Can you tell me what Intel(R) Wireless card you have installed?
You can find that information within "Device Manager", Under "Network Adapters"
It is an Intel PRO/Wireless 3945abg mini card.
Just to make sure that I'm not confusing anyone:
"Ok, here's my story: I've got a Dell Inspiron laptop (from 6 years ago), and even when I first bought it (laptop), it (Bluetooth) didn't work." The laptop itself worked fine at first, and still does. Sorry if I made it confusing.
