intel wifi link 5100 driver for linux mint 17

It seems that installing and updating software can lead to unforeseen, bad side-effects that I don't have the skill to foresee. Most of the problems I've had with Ubuntu so far have been solved with copy pasting terminal commands without knowing what they do, but it feels like the more I do this the more brittle the whole system becomes (because I don't know what I'm doing). Maybe the kernel/system/whatever simply doesn't load the driver on boot-up? So since it is already there, I haven't tried to install it to that directory yet (and I'm not quite certain how to do it). This looks very similar to the file(s) that I downloaded from the previous website that I showed. exe files, while it said that I should find.

Plus when I tried to find the driver for this adapter, I could only find. This is the link that I wanted to use to try to install iwlwifi (I first wanted to try a Linux driver instead of the whole Windows wireless Driver thing. So my WiFi adapter is unclaimed, which I've read means that no driver is associated with it. But if was after the reboot (Ubuntu wanted me to reboot) that my WiFi no longer works. In order to try to fix Spotify (native) (couldn't start it), but I've since learned that update does not actually update any packages (correct me if I'm wrong). Hi, I installed Ubuntu 12.04 yesterday and WiFi worked out of the box.
