TL;DR — small space: single router; bigger/complex: mesh (prefer wired backhaul)
If your home is < 1,200 sq ft on one level, a single high-quality Wi-Fi 7 router placed centrally usually beats a budget mesh. For ≥ 1,800 sq ft, multi-story, or tough materials (brick, plaster, foil-backed insulation), choose a Wi-Fi 7 mesh with wired backhaul—you’ll keep 6 GHz clean for phones/laptops and eliminate dead zones.
Speed ≠ coverage. 6 GHz (and 320 MHz channels) are fast but don’t punch through walls like 5 GHz.
Design for coverage first, then speed. Mesh is a coverage tool.
Range & walls: the physics (quick)
- 2.4 GHz: longest reach, lowest capacity—good for IoT, not 4K streams.
- 5 GHz: best balance of reach/capacity; handles a couple walls.
- 6 GHz (Wi-Fi 6E/7): highest capacity (Wi-Fi 7 up to 320 MHz), shortest reach; shines in same/adjacent rooms.
Materials matter: concrete, brick, tile, plaster + lath, and metal HVAC kill signal. One “super router” at the far end of a house is worse than two modest nodes placed correctly.
The 5-minute home audit (decide fast)
- Square footage & floors: <1,200 sf single level → likely single router. ≥1,800 sf or multi-story → likely mesh.
- Construction: Brick, concrete, tile baths, metal ducts → lean mesh.
- Where you use Wi-Fi: Office, TV room, bedrooms—can one central spot see them all with ≤2 walls?
- Backhaul options: Can you run Ethernet (or MoCA/Powerline) between where nodes would sit?
- Device load: 30–50+ devices (cams, TVs, consoles) → mesh spreads the airtime load better.
Decision matrix: single vs mesh
| Home scenario | Pick | Why |
|---|---|---|
| Apartment/condo, 600–1,200 sf, open plan | Single Wi-Fi 7 router | Central placement covers all rooms; less interference, fewer hops. |
| Ranch 1,600–2,200 sf or L-shape | Mesh (2 nodes) | Ends of house need a nearer radio; place nodes 30–40 ft apart with line-of-sight. |
| Two-story 2,000–3,000 sf | Mesh (2–3 nodes) | One node per floor near stairs/landing; align vertically to reduce walls/floors. |
| Brick/plaster or metal-heavy construction | Mesh + wired backhaul | Walls eat 6 GHz; wired backhaul preserves capacity for clients. |
| Smart home (50+ devices), cams, multiple TVs | Mesh | Distributes airtime; OFDMA + MU-MIMO efficiency across nodes reduces congestion. |
Mesh architecture: backhaul matters more than the box
- Wired backhaul (best): Ethernet between nodes gives you full 6 GHz capacity for phones/laptops. MoCA (coax) is a strong plan B.
- Wireless backhaul (good): Prefer tri/quad-band mesh with a dedicated backhaul (often 6 GHz). Wi-Fi 7 adds MLO, improving reliability via multiple links.
- Single router “range extenders” (avoid): Half-duplex repeaters cut throughput and add latency; only use if you can’t place a node sensibly.
- WAN/LAN ports: Ensure the primary node has at least one 2.5G port; otherwise ISP or LAN copies will bottleneck.
Pro tip: If you can wire only one link, wire the two most distant nodes. You’ll free the air for clients where it matters most.
Placement that actually works (room-by-room)
- Primary router: Central and high (eye-level on a shelf). Avoid cabinets, TVs, aquariums, and metal.
- Node spacing: Start ~30–40 ft line-of-sight; reduce through heavy walls/floors. Aim for −55 to −65 dBm between nodes.
- Stairs & landings: Great vertical “chimneys” for multi-floor homes; align nodes vertically if possible.
- 6 GHz reality: Best in same/adjacent rooms—use it for phones/laptops; let 5 GHz handle farther rooms.
- IoT segregation: Keep 2.4 GHz enabled for smart plugs/sensors; don’t force everything to 5/6 GHz.
Common pitfalls that create dead zones
- ISP gateway + separate router (double NAT): Put the ISP box in bridge mode or your router in AP mode.
- Hiding hardware: Inside media cabinets or behind TVs = terrible signal. Give the radios some air.
- Mixing random extenders: Breaks steering and slows down the whole network.
- Forgetting firmware: Wi-Fi 7 performance improves with updates—apply them.
- One SSID per band: Use a single SSID unless troubleshooting; modern gear steers clients well.
Quick setup checklist (single & mesh)
- Name once, secure once: One SSID, WPA3, strong passphrase. Disable legacy b/g protection modes.
- Enable 6 GHz: Keep 6 GHz on to unlock Wi-Fi 7 benefits; don’t hide it behind a separate SSID unless testing.
- Channel width: Auto is fine; Wi-Fi 7 can use 320 MHz where clean, otherwise 160/80.
- Backhaul choice: Wire what you can; if wireless, place nodes with clear sightlines.
- Test plan: Run a quick speed + latency check in each room; move nodes 5–10 ft and re-test if needed.
