Map the home before the hardware
Mark the internet entry point, rooms that need reliable service, masonry or plaster walls, and stairwells that block vertical signal. Nodes need a strong connection to each other; a satellite parked inside the dead zone just repeats weak signal.
Two stories add a vertical problem: signal spreads sideways better than between floors. A node on each floor near the stairwell usually beats two nodes on the same floor.
Backhaul first, bands second
Ethernet backhaul between nodes removes the wireless relay penalty entirely. Without it, the mesh must spend radio capacity talking to itself — quad-band systems like Orbi 970 and ZenWiFi BQ16 Pro reserve extra spectrum for this, which is why they cost more.
If the home has Cat 5e or better in the walls, mid-range tri-band mesh (Deco BE65 Pro class with 5GbE ports) often outperforms wireless-backhaul flagships at lower cost.
- Ethernet available: prioritize node port speeds over wireless class.
- No Ethernet: prioritize dedicated or quad-band backhaul capacity.
- Thick walls (brick, plaster, concrete): add nodes before upgrading classes — walls attenuate 6 GHz fastest.
