Honestly, the mesh wifi solutions are pretty decent; I've never had luck with the repeaters at all even without interference. MoCA can work, my last experience with it was 5 years ago but I found the connection to be flaky and unreliable. I actually had slightly better luck with powerline ethernet, but that was still flaky and both systems required fiddling with the hardware at least once a month. I have the previous gen Eero (with 2x ethernet jacks per station) and have had excellent luck, my desktop is connected to the farthest station from the modem and I have little trouble saturating my crappy residential cable connection. My only main gripe is the hardware is only configurable via phone app and I assume Amazon is spying on me. However, in 3 years I have only had to mess with the system once after one of the stations didn't rejoin automatically after a power loss. Plus, it provides absolutely fantastic coverage to a oddly shaped property that is very long and narrow with a metal sided garage workshop on the end. But the limited options available are seriously annoying, you can basically only set dns and basic filtering/port forwarding.
