I find PLN more reliable than wifi, nearly as reliable as ethernet. If that’s true, then for some homes PLN is a superior solution in terms of complexity, wiring,,,, See https://tedium.co/2020/06/02/powerline-networking-history/

Whenever I need uninterrupted connectivity for telecommute, I avoid home wifi (including mesh)… too unstable. If I can’t run a long cable across rooms, then PLN is my default choice.

— frequent power-down rest

I have learnt from experience that PLN devices need ventilation and periodic power-down. I think some models can become hot quite easily. My current pair of devices are identical 🙂 and therefore interchangeable.  One of them is easy to power-off, and gets more “rest”. So I devised a rotation plan, so each one periodically rotates to the light-duty position. Is this a burdensome or reccreational complexity? R
