I recently found my old Dell Latitude D520 and I decided it would be a learning experience to try and dual boot Ubuntu on it and play with a new operating system. I installed Ubuntu but to my surprise it won't connect to any network, wired or not. It didn't seem to recognize any network cards at all on my laptop.
Now, I'm an utter noob at Linux and Ubuntu and I've got no clue how to install any types of drivers. Could somebody help me here, giving me explicit instructions?
Edit 1: I downloaded Ubuntu 12.04.4. It is my assumption that no network cards are being recognized because Ubuntu is telling me there are no network devices available. As well, plugging in an Ethernet cord doesn't seem to do anything as I still cannot connect to the internet or my home network.
