I recently restored a Dell 600m, and no drivers for the wireless or ethernet were installed. So I plugged in a 3G stick, and Windows couldn't automatically find any drivers for it online, so I went to Dell.com, and found my model, but there's like 25 network drivers to choose from. Searching using the service tag doesn't come up with any network drivers. I've tried using the driver reset utility, doesn't work at all. And it did not come with a disc. I can only remember that it was an Intel PRO Set Wireless.
