+1 for MoCA

I switched from powerline to MoCA about 10 years ago, and it was a huge step up. Even though it’s half duplex, since MoCA version 2.5, there is enough total bandwidth available to sustain 1 Gbps in 2 directions simultaneously, so it is functionally almost equivalent to full duplex 1 gig Ethernet (except for few ms of extra latency)

To differentiate it from O - making 0 narrow is a common way to do that

The #1 best show is Twin Peaks: The Return of course :)
