Wifi to ethernet
(lemmy.world)
Community for discussing enterprise networks and the ensuing chaos that comes after inheriting or building one.
Another option is if you have coax installed for tv/cable, and aren't using it, even just in the rooms you want to connect wires through, MoCA might work.
I use MoCA and I really like it. It does add 2-3ms of latency compared to pure ethernet, but it's still better latency than Wi-Fi and much better throughput. I use it cause I'm renting and it means I can use the existing coax.
