I’m a newbie trying to put an efficient WiFi network throughout my ~3500 sq ft house. I have gigabit Internet service through Verizon, with a Fios router downstairs and an existing Google WiFi mesh setup that I think is the root cause of the existing inefficiency. My home is not wired for Ethernet but is for coax.

I’d like to understand roughly what I should buy to replace this mesh system with something better. Is it:

• A new (wireless?) router
• 2-3 wireless access points (Wifi 5? 6? 6E? Brand recommendations? Same brand as the router?)
• 3-4 MoCA 2.5 adapters (if MoCA is a reasonable approach)

I’d love to avoid solutions that involve doing a lot of handy work (running cable, ceiling mounting access points, etc.) or a very complicated IT setup (rack mounts, always-on computers, etc.). I do not have cable, and I have heard that MoCA could get shared with the neighbors, so I’d like to prevent that. Any recommendations?
