Choose a mesh setup around a viable path between floors before choosing the highest Wi-Fi speed label. If you have Ethernet between floors, consider a system that supports wired backhaul; otherwise, place wireless nodes where they can still connect strongly to the preceding node, then test their links. Faster ports and higher-tier Wi-Fi matter most when your broadband connection and devices can use them.
If a single router struggles to reach another floor, focus on where you can put an intermediate node, not just the kit’s advertised speed. Ofcom notes that larger homes may need more mesh units for full coverage, while Google advises placing points where they retain a connection to the rest of the network.
If you already have cabling, a compatible wired-backhaul system can carry the connection between nodes without relying on a wireless hop. TP-Link identifies this approach as useful for multi-storey homes and latency-sensitive use; the exact wiring rules still depend on the system.
If several people use the network at once, compare the system’s bands and ports with your broadband plan and devices. NETGEAR’s Orbi 970 range illustrates the higher-specification route with quad-band Wi-Fi 7 and 10 Gig wired connectivity, but those features are relevant only where the rest of the setup can use them.
Decide whether nodes can be connected by Ethernet, then work out where each unit could sit between the main router and the rooms with weak Wi-Fi. The concerns below describe consumers choosing mesh Wi-Fi for use across a multi-storey home.
Choose when: Running cable between floors is impractical and each node can sit within reach of the router or another node.
Trade-off: Floors, walls and placement affect the node-to-node connection, so test the mesh after installation. Google advises placing points towards the weak area rather than at its farthest end.
Choose when: Usable cabling connects the intended node locations, particularly if a wireless link between floors is unreliable.
Trade-off: Wiring takes more planning. Confirm support on the exact model and check its ports, switches and connection layout; TP-Link says a wired link avoids the wireless node-to-node hop.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage between floors | Map weak rooms and possible intermediate node positions; test links after setup. Google recommends open locations and points no more than two rooms from another point. | If the loft or upstairs rooms lose the signal, I need each node to reach both the next node and the room I use. Around 36% of consumers put floor-to-floor coverage first. |
| Wired-backhaul stability | Check backhaul support on the exact model, its ports and the required wiring layout. For ASUS AiMesh or ZenWiFi used with a switch, ASUS recommends Gigabit-capable switching and CAT5e-or-better cable. | With Ethernet between floors, I want calls or gaming away from the main router to rely less on a wireless node link. Wired-backhaul stability comes first for around 29% of consumers. |
| Capacity and faster connections | Compare your broadband speed and active devices with the kit’s Wi-Fi bands and Ethernet ports; do not treat a combined system speed as one device’s speed. | When several devices are busy at once, I care whether the network connections match what the household uses. Around 21% of consumers prioritise capacity for simultaneous use. |
| Setup and compatibility | Confirm how the kit connects to your existing internet equipment, whether it needs an app or account, and whether new nodes can join your current mesh family. | If I am expanding a network or setting one up for someone else, I need to know I can manage it and keep it secure. Setup and compatibility are the primary concern for around 14% of consumers. |
A mesh point cannot pass on a strong connection if its own link to the router or another point is weak.
Place it partway towards the problem room in an open location, then use the system’s mesh test or placement check and move it if necessary. Google gives this approach in its placement guidance.
A faster-labelled kit does not resolve a missing or poorly positioned link to an upper floor. Ofcom notes that larger homes may need additional units for full coverage.
Mark the rooms needing service and the places a node could connect reliably before deciding whether a two- or three-unit kit provides enough placement options.
Mesh equipment distributes an existing connection; it does not replace an inactive broadband service. TP-Link says Deco requires an external internet source.
Identify your modem, ONT or existing router, and check how the proposed mesh system must connect to it.
An app or account requirement may affect who can manage the network, while incompatible generations may prevent an existing mesh from being expanded. Google says Nest Wifi Pro cannot join an older Nest Wifi or Google Wifi mesh.
Check the exact family and setup method before buying. After installation, follow the National Cyber Security Centre’s advice to change a router’s default password to a strong, memorable one.
Deco covers several Wi-Fi generations, so the model matters more than the family name when comparing bands, ports and backhaul.
The Orbi family includes systems with different pack sizes and connection capabilities; compare the precise series before choosing.
ASUS offers a router-style mesh route for households considering compatible routers or ZenWiFi units, including wired installations.
Google’s mesh family offers placement guidance and post-setup mesh testing, but expansion and wiring options depend on the generation and device.
These two- and three-unit mesh kits offer different starting points for placing nodes across floors. Check the path each node can take through your home; if you intend to wire nodes together, confirm Ethernet-backhaul support and the required connections for the exact model.

Three units give you positions to plan between the main connection and rooms on other floors. The Joybuy listing identifies this variant as dual-band BE3600 with 2.5Gbps Ethernet and app-based setup; check its backhaul connections if you intend to wire the units together.

Consider the three-unit pack if your layout has viable intermediate node positions. If you have Ethernet between floors, confirm this exact variant’s backhaul connections and port arrangement before planning a wired installation; TP-Link says Deco setup requires its mobile app and a TP-Link ID.

This three-unit option is relevant if you are comparing tri-band kits for several node locations. Plan placement around the building rather than treating the Wi-Fi label as a coverage guarantee; check the exact Ethernet ports and backhaul options if wired links are part of your plan.

A three-unit kit offers several possible node locations for a multi-storey layout. If faster wired connections or Ethernet links between nodes are important, check this model’s port specifications, backhaul support and wiring rules before choosing it.

This router-and-satellite bundle is worth considering where one additional node can sit along a viable path to the weak area. With only two units to position, check whether that path reaches the rooms you need; confirm port and backhaul details if you plan to use Ethernet.
Choose the number from the usable path to weak rooms, not floor count alone. Google advises placing a point partway towards the area needing coverage and no more than two rooms from another point; test the mesh after setup and move a node if its link is weak. Ofcom notes that larger homes may need more units for full coverage.
Ethernet backhaul is worth considering when cabling is available and a wireless link between floors is unreliable or latency matters. TP-Link says it avoids using wireless capacity for the node-to-node hop. Before buying, check the exact model’s support, ports and required wiring layout.
Check the generation before buying an expansion node. Google says Nest Wifi Pro cannot be combined in one mesh with older Nest Wifi routers or points, or with Google Wifi points.
Use Wi-Fi encryption, change default router credentials and apply firmware updates available for the exact system. The National Cyber Security Centre specifically recommends replacing a router’s default password with a strong, memorable one; check your kit’s settings after installation rather than assuming every option is enabled.
