If it's a newer house with drywall / sheetrock, take the money you would spend on the powerline ethernet
equipment and take a drywall class. You said "we" so let your spouse/partner/roommate learn to paint.
Then pick your spot, whack a hole in the wall and stick in a conduit.
A 2" PVC conduit fits nicely in a standard 2x4 stud wall.
Then if it's network from the basement to the attic and then down to the computer room or
TV antenna from the attic to the basement to the TV distribution splitter, you're all set.
Even with satellite or cable TV there's usually more local HD channels OTA.
