Has anyone tried this approach in the USA? I use ethernet over power line to transmit signals through the house. By the time my 1Gig internet service gets from the modem to the furthest end of the house, I’m getting 30 - 40 Meg speeds at the TV. OK for 4K TV, but still some fluttering and buffering. I have RJ-11 ports at both ends.
There is a typo in there, you don’t really mean 30 - 40 Gig..
Powerline adapters can work across different electrical circuits, but performance is significantly reduced. They operate best when on the same circuit, as different circuits may introduce noise, phase differences, or filtering that degrade the signal.
Performance & Limitations
-
Speeds vary: Real-world performance is often lower than advertised (e.g., 200 Mbps kits deliver ~20–90 Mbps).
-
Best on same circuit: Performance drops if adapters are on different electrical circuits.
-
Interference: Large appliances (microwaves, refrigerators), surge protectors, or outdated wiring can degrade signals.
-
Latency: Higher than direct Ethernet, but suitable for most gaming and streaming if stable.
That’s why I think if the house has the old cable lines to every room it would be better.
Fixed. Thanks.
Miki, found a product on Amazon claiming to work on unused/dormant cable lines. It says no need for MOCA standard on the cables, so I don’t have to find and update the splitters to MOCA. 3 weeks to ship from China. I’ll report after I’ve tested it.
I have heard of this method before. More commonly I believe IMHO, that old electrical lines and telephone lines can be used for wiring sound system
