Households with several weak rooms
Wi-Fi works near the router but becomes unreliable upstairs or in other distant rooms. They need to consider coverage across more than one location, not just a single dead spot.
Who needs better coverage?
Households with Ethernet near weak areas
A cable can reach a useful node or access-point location. This makes a wired connection between network devices an option for streaming, gaming or video calls.
Households keeping their provider’s router
They want to extend Wi-Fi without replacing the existing broadband setup. The added equipment’s operating mode and required physical connections matter to that choice.
What matters when choosing?
Start by locating the weak areas and checking whether moving the router helps. Then decide whether you need coverage across several rooms, a wired connection at a particular location or a smaller extension to one area.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Map the weak rooms and possible node positions. Try a more central router position before choosing how many mesh units you need. | If Wi-Fi drops off on several floors, I need coverage beyond the room containing the router; around 33% of consumers put multi-room coverage first. |
| Connection between nodes | Check whether Ethernet reaches useful locations and whether the chosen mesh system supports wired backhaul. | For video calls or gaming in a distant room, I want a dependable connection between network devices; around 25% of consumers place that need first. |
| Existing-router setup | Confirm the required wiring and whether the added equipment will route traffic or run in access-point mode. | I want to keep my provider’s router managing the network without an awkward setup change. Keeping that arrangement is the primary concern for around 25% of consumers. |
| One weak area | For a wireless extender, find a position that still receives a usable router signal; compare a wired access point if Ethernet reaches the area. | Only one room needs attention, so I would rather address that spot than install nodes throughout the home; around 17% of consumers prioritise this limited fix. |
Ofcom advises that router placement affects home Wi-Fi and that mesh systems can improve signal strength and coverage. It also cautions that wireless boosters and extenders can affect speed and responsiveness. For TP-Link Deco, TP-Link describes Ethernet backhaul as a wired alternative to the connection between nodes; check the selected model’s supported setup.
Mistakes to avoid
-
Buying mesh to fix slowness everywhere
Mesh can improve the wireless connection around the home, but it cannot raise the speed of the incoming broadband service. Ofcom distinguishes in-home Wi-Fi coverage from the connection feeding it.
Compare the connection close to the router with the connection in weak rooms. If both are poor, check the service with your broadband provider before buying coverage equipment.
-
Putting an extender in the dead zone
A wireless extender needs to receive the existing Wi-Fi signal before it can extend it. Ofcom notes that extenders can also affect speed and responsiveness.
Position it between the router and the weak area, then test the result. If Ethernet reaches that area, consider a wired access point instead.
-
Assuming mesh connects to the old router wirelessly
TP-Link says the main Deco unit needs a physical connection to the modem, router or internet cable; it is not a wireless repeater for the existing router.
Check the selected system’s connection diagram and operating modes. Decide whether the existing router will remain responsible for routing before arranging cables and nodes.
-
Treating a coverage figure as a guarantee
Walls, floors and a home’s layout affect where Wi-Fi reaches. A stated coverage area cannot determine the result in every property.
Plan node positions around the actual weak rooms and building layout, including whether Ethernet can connect any of the locations.
Brands to consider for these setups
TP-Link
Relevant to households comparing Deco mesh systems, compatible extenders and ways to retain an existing router.
- TP-Link says Deco can run in router or access-point mode and that supported Deco units can combine Ethernet and wireless backhaul.
- Check the exact model, operating mode and compatible devices; product-family guidance does not establish every feature for every unit.
NETGEAR Orbi
Relevant when considering a multi-unit mesh setup and comparing the specifications of individual Orbi packages.
- NETGEAR lists tri-band Wi-Fi 7, a 2.5 Gig internet port and a wired-backhaul option for its Orbi 770 RBE773 package.
- Those specifications belong to that package, not every Orbi system. Check the package and connections needed for your home.
ASUS
Relevant to households considering a router that can serve as a wired access point behind their existing equipment.
- ASUS describes access-point mode as using a wired connection to the primary router or modem to extend Wi-Fi coverage.
- ASUS says routing functions are disabled in that mode and support varies by model. Confirm the model and the primary router’s setup before buying.

TP-Link Deco BE65 BE9300 tri-band Wi-Fi 7 mesh system (3-pack)
A three-pack mesh option for extending Wi-Fi across multiple rooms.
Confirm the package contents, available Ethernet connections and operating mode needed with your existing router; the home’s layout will affect coverage.

TP-Link RE220BE BE3600 Wi-Fi 7 range extender
A range extender to consider when one weak area can still be reached from a position with a usable router signal.
For wireless extension, plan a position between the router and the weak area rather than inside the dead zone. Confirm compatibility if you need it to work with an existing mesh setup.
Common questions
Should I move my router before buying new Wi-Fi equipment?
Yes, if its current position could be limiting coverage. Ofcom advises placing a router centrally, off the floor and away from obstructions and sources of interference; test the weak rooms again after moving it.
Will mesh Wi-Fi speed up a slow broadband connection?
No: mesh can improve Wi-Fi coverage inside the home, but it cannot make the incoming broadband service faster. If the connection is poor close to the router as well as in distant rooms, check the service separately.
Can I add mesh Wi-Fi and keep my provider’s router?
You can with some systems, but check the selected product’s supported mode and wiring. TP-Link says Deco can work with an existing router in router or access-point mode, with its main unit physically connected; access-point mode lets the existing router retain its network-management role.
When should I consider Ethernet backhaul?
Consider it when a cable can connect useful mesh-node locations, particularly where floors or walls separate them. TP-Link says supported Deco units can use Ethernet backhaul instead of a wireless link between those units; confirm support on the exact system you choose.
