I moved to a new house where the network is the worst. The AT&T fiber runs downstairs in the garage and then up the CAT6 to the laundry room where a patch panel distributes the CAT6 back to the family room and upstairs to the master bedroom. My downstairs office doesn't have ethernet, so I used a Netgear Orbi Pro (which I really don't like) to connect ethernet to my switch in my office, but throughput rarely exceeded 300Mbps, even to the access point and the destination here is the connection to my office at 1Gbps. I tried powerline first, which is a waste of time and doesn't go above 100Mbps unless you're on the same network. I found it in desperation when it occurred to me that there is coax in every room, so I did a search to see if I could use it and found it, although I didn't have much hope that it would work . When they arrived I just connected one end to the coax cable in the laundry room upstairs and then directly to the router using Cat 6e cable. The other end is downstairs in my office, connected with a coax cable, then Cat 6e to my desktop computer's ethernet port. The connection lights on the boxes and endpoints lit up immediately, and syncing took less than a minute. I did a speed test and was amazed that the speed on my desktop below was the same as if I was connected directly to the router above. I have 980 Mbps, which is the max gigabit throughput with ethernet overhead. and I'm using a Cisco RV340 with 1Gbps bandwidth. So yes, it works! Alternatively, you can plug one end directly into a coax splitter and then place them in any room that requires Ethernet. However, I don't know what the speed would be if all nodes were transmitting at 1Gbps at the same time. BUT that's not my goal, so I'm very, very, VERY happy with the results (and for the record, I'm a former Cisco employee and Gartner Network Industry Analyst - in case that matters).
