Review on TRENDnet Ethernet Over Coax Adapter (2-Pack) - Backward Compatible with MoCA 1.1 & 1.0, Gigabit LAN Port, Supports Net Throughput Up to 1Gbps, Up to 16 Nodes on One Network - Black (TMO-311C2K) by Ryan Garrison

Our house was "connected to the internet in all rooms" - this meant that the coax cable was in every room but not connected to anything. Our router/modem was installed in the living room since AT&T was installed. There was need in the basement. nothing was connected to the coax and the wireless signal throughout the house was terrible. Each of the coax ports in the rooms led to the basement, but didn't connect to anything. These adapters worked great. One in the upstairs office to connect computers to the coax, a coax splitter in the basement to reroute the coax from the bedrooms to the living room, and another adapter in the living room to connect the main coax to the router. All I had to do was hook them up to coax/ethernet and BOOM internet throughout the house. No customization, so you need to return things or buy extra parts. Just plug in and get started. We solved our problem cheaper than paying another internet plan or someone to connect our home to an ethernet network.
