Hello Homelabbers!

I moved house a while back, from my parents to my own (private rent) apartment. My fibre from my ISP comes in at a certain point of the building, and I want to run a network cable to the bedroom. Because it's a private rental, I can't easily run cables between the rooms as I would need to get permission, and the walls are all solid brick anyway

Are power line networking products still as bad as I remember them, or are they good nowadays? Are there any brands that are preferred over others? I have a 1Gbit symmetrical connection to distribute around the place so any product that can handle that or at least a high percentage of it would be good.

I'm still looking at running a cable between rooms as there' a 4 foot void under the floor across the various floor spaces, but it's not that accessible from above (I would have to use an RC car to get cabling in place!)
