I've got a tv mounted in my living room, and the router/modem/service connection is on the other side of the house on the same 2nd level. The WiFi is usually adequate but there's just enough signal drop between the multiple interior walls and microwave that we'll get stutters or buffering as the video drops in quality, and then another stutter as it jumps back to a higher res. Ideally I wouldve liked to have run Ethernet into my attic and drop in behind the TV, but the living room ceiling is vaulted. My first thought is to run some plenum rated cable along the HVAC to the living room and enter the wall behind some baseboard, but fishing cable along the HVAC sounds like a terrible time. My next thought is to just run some exterior conduit which would be an easier solution but also the ugliest. Last option is a mesh network/Moca/power line adapter which would probably be easiest and work well, but lacks the diy satisfaction we all love. Plus I'm just an Ethernet fan boy. Any input or advice is welcome.
