We finally rewired our home network. Ethernet now reaches all the way to the home office. Non-scientific measurement comparison in screenshot below
@freddy I tried to re-cable as well, but couldn't drill a hole through the wall. Kept hitting iron rods (load bearing wall). So I reused the coaxial cable already there with a MoCA 2.5 adaptor. I get roughly 2 Gbps. TV still works as well.
I love wired networks as well.
