It's always possible, but not often practical, especially when you don't have permission to drill holes in those concrete walls.

I suppose you could do surface runs, but those are ugly and more vulnerable to physical damage.

But I wasn't facility. I was a student.

The dorm itself did not have internet and had no plans of running ethernet or providing internet to students.

I got internet through a wireless access point, positioned very carefully in window for a WISP. And they distributed that to rooms near me.
