A:Answer Possibly. Do you have a current router? If so, what type & how well does it work? What does this particular router add that your old one lacks?
Our solution to reach from main floor to basement was to add a Range Extender. Find an extender that supports both 2.4 & 5GHz, with the ability to use one of the bands as a "back haul" channel. Ours is an older Linksys, but works perfectly well with 2 running computers & a Roku in the basement - with a few odd minutes of smartphone connectivity tossed in for good measure.
MUCH less expensive than a "mesh" system.
