LOL ,fair enough – I must have looked at the US one (despite the subject line here) – why US isn't discontinued, dunno.
@mkx is exactly right...the wiring/breakers determines how well any of these ethernet-over-power things work. And imagine Mikrotik deals with a lot of returns as a result of that
.
I'm not sure it a Mikrotik thing here – I've wanted the Powerline to "just work" for longer than a decade. I have a box with various TPLINK, Netgear, and now a set of the MT PWR-LINE PRO in that graveyard, none have worked well unless all the electrical things align & even then still never consistently 100Mb+ despite all vendors claims. And often don't even sync – generally explained by tracing down what breakers things are on. Wi-Fi bridging seems more consistent if you cannot run a cable IMO.
Maybe if you some phase coupled Devolo things in the panel might help , but I'm skeptical on the technology...
