I’m using Devolo 1200+ series, I have four of them around the house and am really impressed.
My previous house was Cat6 wired throughout so got used to that, since moving in July I’ve been struggling with some out TP Link ones which weren’t the best. Upgraded last week to the 1200+ mb/s and getting a good transfer rate throughout, enough to stream mkv’s rips of bluerays to each TV from my NAS, along with audio throughout and the house is now saturated with WiFi that actually works rather than extending Wifi over the air.
I am seeing 400mb/s pass through on the links which is enough, although houses with older wiring would be slower obviously.
Depends how much you want to spend, but if you are doing high bandwidth about the house, get as good as possible and forget about them as they’ll just work.
Still have stupidly slow BB thanks to BT refusing to ugrade my cap to infinity, but thats another story.
