So, my house was built well before houses were wired for ethernet, and in two parts, one of which doesn't have any good way to pull wires.
For years I used various wireless solutions to bridge, moving to MoCA 2.5 later on, but there were aspects of both that caused problems with some applications.
I recently replaced that with an Invisilight fiber kit, which worked *great*. Easy, invisible, effective. Good stuff.
