Hey,

I am planning to get three Deco X20s to have mesh wifi in my house but I have no clue if this will give me a horrible gaming experience. The setup I am planning to do is:

ISP Router (in bridge mode or maybe just no Wifi) -> Main Deco Parent -> Satellite Deco -> Satellite Deco -> PC

All of these connections are wired and I am hoping to use ethernet backhaul. Any ideas of things that can go wrong with this setup? I originally wanted ISP router + one router + range extender but that's causing some range and speed issues on my end.

Cheers
