Sorry, I sholuld have mentioned before that I am renting.
If I owned the place I would definitely just run cables myself, drilling as needed.
I am also not sure MoCA would work either as my modem is hooked to the cable downstairs.
I've also thought about a range extender or repeater. But, having only laptops for the longest time I am not sure how having my desktop on wireless would effect speeds (especially if/when gaming).
