I ran Cat6 from my router-equipped living room into my bedroom. I'm very pleased with the results, here's what I did. I chose a Ubiquiti "Access Point AC In-wall." It's a WiFi AP, with 4 GbE ports, and draws PoE, which means no plugs needed at the point of installation. It looks very clean, just a neat rectangular box affixed to the wall, delivering both WiFi and 4 wired jacks (one doesn't work, oh well). Using a manual drywall saw, I cut a hole in my wall, at the point of installation but smaller than the faceplate, so it would be covered. Next I used an 18 inch spade bit to drill through the sill plate of my floor. This part was the most nerve-wracking: I couldn't see what I was doing through the drywall, and sill plates are very hard. Eventually I busted through, and left the drill bit in the hole as a marker. I climbed down into the crawlspace and fished the Ethernet cable up through the hole, with some help from my wife. I then ran the other end to the living room, just in the crawlspace dirt (stapling it to studs was possible but didn't seem important); the other side had a pre-drilled hole for cable and I fished it up through. I'm not especially handy but wiring my home for Ethernet was a manageable adventure, give it a try!
