I am working on getting wireless up and running on my Ubuntu 12.04 machine. In this
tutorial, the guy says "your network controller is your Wi-Fi." To me, that seems to imply that the network controller is the piece of hardware that handles your wireless connection. Does the network controller also handle your Ethernet connection? When I run
grep for network I see that my Network controller is a Realtek Semiconductor Co. device. What exactly does that device do? My Ethernet is working fine. Do I need to find a driver that will handle both wired and wireless connections for this network controller? Or do I need a Wi-Fi driver for the network controller because the network controller only handles Wi-Fi.
