People sharing several rooms
Meetings, lessons or streaming take place far from the router or across floors and walls. Map the weak rooms before deciding how many wireless points you need.
Who is this for?
Gamers and remote workers using fixed devices
Interactive games or calls make a dependable local connection important. If a cable route is practical, consider Ethernet for the device or between network units.
Homes with many devices online together
When several people and connected devices share the connection, establish whether the constraint is the broadband service, local Wi-Fi or a particular device before replacing equipment.
What matters when choosing?
Replacement router
Consider it when: Most rooms have usable signal, but the current router appears to struggle during concurrent use.
Trade-off: One router may still leave distant or obstructed rooms with weak coverage; confirm broadband compatibility and provider support.
Mesh Wi-Fi
Consider it when: Several rooms or floors need Wi-Fi coverage from more than one unit.
Trade-off: Mesh does not increase incoming broadband capacity, and wireless links between units depend on placement and building conditions.
Wired access points
Consider them when: Ethernet already reaches rooms that need their own Wi-Fi coverage.
Trade-off: Cable routes and network configuration need more planning; check how the chosen equipment works together.
Direct Ethernet
Consider it when: A stationary work, learning or gaming device can be connected by cable.
Trade-off: It addresses that device’s local connection, not Wi-Fi coverage elsewhere or the broadband service’s capacity.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Test the rooms that need a connection; note floors, obstructive walls and possible node or access-point positions. | If meetings and lessons happen away from the router, I need those rooms to stay connected. Around 31% of consumers put room-to-room coverage first. |
| Broadband or local bottleneck | Compare a direct Ethernet test with Wi-Fi results, noting download and upload performance during household use. | Before replacing equipment, I want to know whether simultaneous activity is limited by the incoming connection or the home network; roughly 25% of consumers prioritise that distinction. |
| Wired stability | Identify fixed devices and cable routes; check available ports and the chosen system’s wired-backhaul instructions. | For a fixed gaming or work device, I would rather use a practical cable route than depend on a wireless hop. About 25% of consumers make a wired local connection their primary concern. |
| A simpler router setup | Check service compatibility, required connections and whether a provider router upgrade is an option. | If Wi-Fi already reaches the rooms I use, I want to address a struggling router without adding network units; around 19% of consumers put that simpler change first. |
Buying pitfalls
-
Buying mesh before checking the broadband connection
Ofcom identifies Wi-Fi, in-home congestion and device limitations among the factors that affect experienced performance. Mesh cannot increase the capacity delivered by the broadband service.
Where practical, test a computer directly through Ethernet with other traffic paused, then compare that result with Wi-Fi in the affected rooms.
-
Treating a coverage claim as a guarantee for your rooms
The Wi-Fi Alliance notes that walls, floors and wiring can affect coverage, so a stated coverage area cannot establish where units should go in your home.
Check the actual weak rooms and place mesh units where they can retain a connection to the rest of the system.
-
Overlooking backhaul and Ethernet ports
A wired connection between mesh units needs suitable cable routes, ports and a supported setup. TP-Link and ASUS each document model-specific approaches to Ethernet backhaul.
Count the required connections and check the exact model’s wiring instructions before planning a wired installation.
-
Choosing by headline Wi-Fi speed alone
A Wi-Fi speed label does not tell you the speed of your broadband service or how coverage will work through your walls and floors.
Match the equipment’s ports and supported features to your broadband connection, devices and coverage needs.
Brands to consider for these network routes
TP-Link
Its Deco range is relevant to multi-room mesh coverage, including configurations with Ethernet backhaul.
- TP-Link documents how compatible Deco units can use wired connections between nodes.
- Check the particular Deco model, its ports and the wiring rules for the intended operating mode.
ASUS
AiMesh is relevant when you want a router-led network that can expand to additional compatible nodes.
- ASUS documents wired connections and Ethernet Backhaul Mode for supported AiMesh setups.
- Router, node and firmware compatibility must be checked for the exact combination.
Amazon eero
The eero 6+ range is relevant to app-guided mesh setup and expansion.
- The eero 6+ product listing describes expansion with compatible eero hardware.
- Check the pack and Ethernet ports; some optional security and management tools require a separate subscription.
NETGEAR
The Orbi 770 range is a higher-specification mesh option to assess against a busy home’s actual connections and layout.
- NETGEAR describes tri-band Wi-Fi 7 and 2.5 Gig Ethernet for the Orbi 770 series.
- Those series specifications do not establish the fit or performance of a different Orbi model; compare exact-model ports and coverage needs.
Joybuy product choices
These products address Wi-Fi coverage: three multi-unit mesh systems for gaps across rooms, followed by a range extender for a more localised weak area. Check your broadband connection and cable options before deciding whether wireless equipment is the change you need.

TP-Link Deco BE22 BE3600 Wi-Fi 7 Mesh System, 3-Pack
Consider this three-unit mesh system when Wi-Fi needs to reach several rooms; plan where each unit can connect to the network.
Check the exact model’s Ethernet ports and backhaul instructions if you intend to wire the units together.
No image available
NETGEAR Orbi 370 RBE373 WiFi 7 Mesh System, 3-Pack
The three-pack is relevant when coverage is needed across separate rooms; placement and building conditions still matter.
The product name specifies dual-band BE3600 and 2.5Gbps Ethernet. Check the exact port arrangement and backhaul options for your intended wiring.
No image available
TP-Link Deco BE65 BE9300 Tri-Band Wi-Fi 7 Mesh System, 3-Pack
Consider the three-pack for coverage gaps across rooms, allowing for the home’s layout when planning unit positions.
Confirm the exact pack contents, Ethernet ports and wired-backhaul arrangements before committing to a cable layout; BE9300 is not a measure of your broadband speed.
No image available
TP-Link RE220BE BE3600 Wi-Fi 7 Range Extender
Consider an extender for a localised weak area when it can be placed within range of the existing router; this is not a complete mesh kit.
Check compatibility with your router before relying on any shared-network or roaming features.
Common questions
What should I check before buying a router or mesh system?
Check where simultaneous work, learning and streaming take place, how many devices are active, and whether the affected rooms have weak Wi-Fi. Note your broadband download and upload speeds, then use a direct Ethernet test where practical; Which? recommends a wired connection for a clearer indication of the speed delivered by your provider.
When should I use Ethernet instead of replacing Wi-Fi equipment?
Use Ethernet for a fixed computer, console or other stationary device when a cable route is practical and that device’s local connection is the priority. A cable can also connect compatible mesh units, but check the chosen system’s backhaul instructions before planning the route.
Will mesh make a slow broadband connection faster?
No: mesh can address Wi-Fi reach within the home, but it cannot increase the capacity supplied by the broadband service. Compare a direct Ethernet test with performance in weak rooms before treating coverage as the cause.
Do I need a network switch with mesh Wi-Fi?
A switch is relevant if you need more wired connections than the router or main mesh unit provides; it does not add Wi-Fi coverage or broadband capacity. Count the ports you need and follow the selected mesh system’s documented wiring topology.
