If you don’t care for the looks, just put it down where needed, and fix it to whatever is around with cable ties.
I did the same in my daughters shared accommodation. Officially they had wifi in all the student rooms, but my daughters room basically had no reception, so I ran a cable from the other end of the flat where the router was down the staircase into her room for a local AP. When she moved out, it was a quick job with a pair of pliers to get it out again.
Do you have to break your fingers, too, to switch them off?
