Shit, if I were in college right now, I'd do it from there. Are you kidding? Online shit for a few hours a day, and then beautiful beaches for the rest? Sounds pretty good.

Get a snake. You should be able to work from the outlet and get the snake up to that point, then pull a pull string, then pull your cable through. Cement walls are a real pig on wifi. Other than running lines I have not yet found a good work around.
