A technician came to my house recently and suggested that I might get better TV and networking performance if I have my house re-cabled from coax to Ethernet. FWIW, the current coax wiring in the house was installed in 2010. What I wondered was, if the cabling coming into the house from outside with the Internet and TV signal is on coax, what benefits (if any) would I get from switching to Ethernet inside the house? If anyone has tried this and has any insights or results to share, I would very much appreciate it. Thanks very much!
Since you have what appears to be good coax throughout your house, you might want to consider using MoCA adapters to get wired connections to the various rooms.
Here are some diagrams from GoCoax that show how to use MoCA. Be sure your splitters are 5-1675mhz to support the upper frequencies of MoCA and verify that PoE filters are installed as shown on the diagram that applied to your situation.
Might be a lot more cost effective than pulling new CAT 6 cables through the house.
This is the way.
Ripping out coax and replacing with cat6 will be time consuming and costly. + if that coax is stapled down good luck yanking it out.
