Homeplug is a defunct standard that had some real limitations, Ethernet over Power is a generic term relates to any standard of network over power lines.

The G.hn powerline standard is a massive improvement (despite being almost as old and is closer to MoCA as it will actually work over coax and other copper wiring, not just power lines) for both performance and stability, but the Homeplug standards have probably ruined the public perception.

G.hn is also a bit weird because the Wikipedia page presents it as how carriers could use, not as a home network option, even though a few home pieces of equipment are available, such as the TP-Link Deco PX50 which uses G.hn for the wifi backhaul.

If you use these powerline plugs, your house is also a huge antenna.

My internet access dropped occasionally until a telcom guy found the culprit. It was a neighbor using a Devolo powerlan adapter.

So yes, don’t use these. The only useful frequency in power cables is 50 or 60 Hz.

I live in a house designed by a boomer. Networking comes in the upper floor while nothing is in the lower

These power over Ethernet is the only way I can get networking down stairs.

This post is missing some key information. What’s the network topology before and after? Presumably not just unplugging a pair of powerline adapters.

Fun true story. I tried EoP when I moved into my townhome to feed Ethernet to my TV. For like 6 months I get weird issues where my TV would stop letting me connect from my phone.

Trying to diagnose it, I started disconnecting stuff. Finally, I had a single EoP plugged into wall and nothing else. Still had Internet, WTF …

Turns out one of my neighbors also has EoP and I was connecting to his network. Crazy shit

Went to MoCA after that.

Not surprised, as we were getting higher speeds the Ethernet wire also was upgraded. The electrical wires were never set up with data transfer in mind + you might get additional interferences from other devices plugged in.

So it probably needs to retransmit packets frequently.

I’ve heard of power over Ethernet (PoE for IP cams) but not Ethernet over power.

I once replaced a cheap pair of adapters with a more expensive pair. Was night and day for my network stability. I know it’s hit or miss, depending on your wiring and location. But the adapters themselves can differ.

The users reading this post that think you are referring to PoE are innocent and pure.

Behold. Power line communication https://en.m.wikipedia.org/wiki/Power-line_communication

I did switch from homeplugs to mesh wifi. The difference night and day. Less latency, faster and overall more stable.

I arrived at that conclusion because my servers were using a NAs as storage for most services, all of them separated by homeplugs.

When I relocated the NAS with the servers, everything went smoothly so yeah. Removed all of that and used mesh wifi instead (because the line for internet isn’t in the same room as the servers)

I love my EoP but yes, it’s a big noisy bus. Ok for small checkins and pings etc. like wifi every device on the bus takes a time slot away from another. I do want to see what my electrical upgrade from old wires to thicker gauge inside of grounded EMT does for it though.

you’re referring to the POE (Power over Ethernet) plugs?

I never knew they would cause such problems, maybe it was just that specific brand?
