Wi‑Fi dead zone upstairs
Most upstairs dead zones are not fixed by buying a bigger router. They’re fixed by (1) moving the router for a better vertical path, (2) placing one node at the stairwell/landing (not in the dead zone), and (3) wiring backhaul if the hop is weak.

If the real problem is the garage or a room over it, use: Wi‑Fi dead zone garage.
Fast test
Run the Wi‑Fi walk test. If your RSSI drops sharply at the top of the stairs, it’s mostly coverage/penetration. If RSSI is OK but performance is inconsistent, it’s usually a weak mesh hop (backhaul).
Step 1: stop ‘aiming’ the router wrong
- Get the main router off the floor and out of cabinets.
- Prefer a central spot near the stairwell over an exterior wall.
- If possible, put the router on the first floor ceiling line (high shelf) to improve vertical propagation.
Step 2: place the first mesh node at the landing, not in the dead zone
The winning pattern is a strong uplink first, then spread coverage. Put the first node where it still has a strong signal from the router (often the upstairs landing/hallway). Then place a second node closer to the room that’s dead.
Use: Mesh placement checklist.
Step 3: if the hop is weak, wire it
If upstairs performance is ‘random’ (fast for 30 seconds, then buffering), you likely need a stable hop between floors.
- Best: Ethernet backhaul to the upstairs node.
- Best-no-drywall: MoCA if you have coax jacks upstairs.
Start here: Wired backhaul for mesh.
Common upstairs gotchas
- Bonus room over the garage: extra insulation and ductwork can make it worse than the rest of the upstairs.
- Plaster walls: can behave like a signal shield. See best mesh for plaster walls.
- Concrete/brick: plan for wiring. See best mesh for concrete walls.
