Mesh Network vs Moca/APs
Mesh Network vs Moca/APs
Upgrading your network sounds like a good plan. Your current setup with the Meshforce M3 is working for basic coverage but isn’t delivering the speed you need. The N66U should boost speeds to double, especially on 5GHz, and it will handle multiple SSIDs without issues. The weak point is the limited backhaul, which drops quickly when you move away from the main router. Since your home is large at 5500 sq ft, a more robust mesh design might be worth considering. Think about replacing the M3s with a newer model and see how it improves performance across your space.
Please clarify if this is a single level or multi-level home. A floor plan sketch of your house which highlights the position of your ISP modem/gateway, ethernet runs and other existing network hardware would help a lot. For such a large area, you’re better off mounting multiple wireless APs across the property and wiring them directly to the router/AP. The router does not have to be a wireless router that you have now. It can be a wired-only one since your APs will be handling WiFi and the router will only be handling NAT/DHCP.
