I use MoCA at home, 1 GBit. It works pretty well, and I get almost full speed.

Every now and then I have some blip and have to power cycle on one of the coax-to-Ethernet connector, so that’s annoying. It’s like twice a year, so not a huge problem.

The biggest drawback is high latency. It’s milliseconds instead of microseconds in the house. I guess it’s buffering and framing, so maybe unavoidable.

I also do see some small packet loss. Less than WiFi, but not zero like you’d see from a proper Cat6 cable.

Maybe just but a pair of MoCA adapters to try in your setup?

We were so close to a phone usable by non-enthusiasts with the Nokia N1. The Nokia Linux phones were killed when Nokia hired a former VP at Microsoft to be their CEO. I’m still bitter.

I thought vaporware was announced or promised code that never materializes, or shows up much later than claimed. Often used by big companies to squash competition, who typically have very real solutions available.
