Start by checking whether the broadband connection is unreliable near the router as well as upstairs: extra Wi-Fi equipment will not fix a fault with the service reaching your home. If the problem is mainly in the distant room, direct Ethernet suits a fixed computer when a cable route is practical; mesh is worth considering for several rooms, while a wired access point or suitably placed extender addresses a more localised gap. Consider replacing the router only when it appears to be the limiting factor and your ISP confirms the connection can be configured.
If calls work near the router but falter in one or more distant rooms, consider where extra Wi-Fi units could be placed and how they would connect back to the router. Ofcom notes that distance and obstacles can weaken Wi-Fi signals.
If you work at a fixed desk and can run a cable safely, a direct Ethernet connection may be a practical alternative to extending wireless coverage throughout the home. Ofcom recommends considering Ethernet for a computer that needs a dependable connection.
If you want to keep your ISP router, check whether added equipment can work with it, how it must be connected and which network controls remain available. TP-Link and eero document different cabling and feature requirements for their respective operating modes.
Compare the connection near the router with the one at your desk before choosing equipment. Ofcom advises checking the in-home Wi-Fi connection separately from the broadband service reaching the home.
Consider it: for a fixed work computer when a practical cable route reaches the desk.
Trade-off: it connects that computer, but does not extend Wi-Fi to phones or other upstairs devices.
Consider it: when several distant rooms need coverage and there are suitable positions for multiple units.
Trade-off: wireless backhaul still relies on the connection between units; some systems also require their main unit to connect to the existing gateway by Ethernet.
Consider it: when checks suggest the existing router is the limitation and your ISP confirms the replacement can use its connection.
Trade-off: one router may still struggle to reach an upstairs room through floors or substantial walls, and setup can depend on your ISP.
Consider it: for Wi-Fi in a local area, using a wired access point if Ethernet reaches it or an extender where the existing signal remains usable.
Trade-off: an access point needs a wired feed, while an extender cannot make an unusable incoming signal strong; mesh-style roaming depends on device compatibility.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Coverage at the upstairs desk | Compare the connection near the router and upstairs; check unit placement and whether wired backhaul is possible. | If several upstairs rooms lose calls, I need coverage across those rooms, not just a connection beside one socket. Around 36% of consumers put multi-room coverage first. |
| Wired connection at a fixed desk | Check that a cable can reach, the computer has Ethernet and the router has a spare port; distinguish direct Ethernet from a mesh unit with wireless backhaul. | For a fixed work computer, I want a direct cable if the route is practical. Around 29% of consumers prioritise a wired desk connection. |
| Keeping the ISP router | Check the required Ethernet connections, operating mode and which network controls may change. | If I need to retain my ISP hub and its controls, I want added equipment that fits that setup. Around 21% of consumers put hub compatibility first. |
| Replacing one router | Check whether the problem also occurs near the current router, plus the replacement’s ISP connection requirements and ports. | If the router itself seems to be the issue, I want to know that before replacing it; a distant-room problem or broadband fault may need a different response. Around 14% of consumers prioritise a single-router refresh. |
Better in-home Wi-Fi cannot fix a problem with the broadband service reaching your home.
Compare results near the router and upstairs, and check with your provider if the connection is poor even near the router.
A computer connected by cable to a wirelessly connected mesh unit still relies on Wi-Fi for the unit’s link back through the network. eero describes this limitation for its wireless eero connections.
Check the full path from the work device to the router, including how the mesh unit itself connects.
Depending on the layout, a different unit or a cable for wired backhaul may also be needed.
Mesh operation can depend on compatible equipment and the particular model version; ordinary signal extension and compatible mesh roaming are not the same thing.
Check the manufacturer’s documentation for the exact router and extender pairing before choosing a device.
Wiring requirements differ by system and mode, and bridge mode can disable some network features.
Check the wiring instructions, the controls you need and any remaining Ethernet-port or power requirements before buying.
Your layout may also call for cabling, a network switch or power equipment for an access point.
Its documented UK range includes Deco mesh systems, Archer routers and RE-series extenders, covering several different ways to address an upstairs connection.
The eero 6+ is a mesh-capable router option to compare when considering gateway and additional-unit arrangements.
ZenWiFi XD5 is a documented multi-unit option with Ethernet backhaul; ASUS also provides guidance on checking WAN connection types when replacing a router.
The Halo H80X is a multi-unit mesh option to compare by its kit contents, Ethernet ports and expansion compatibility.
The U6+ is a wired access-point option to consider when Ethernet can reach the area that needs Wi-Fi.
These options cover mesh kits, a local range extender and single-router choices for improving upstairs home Wi-Fi. Check the connection requirements and compatibility of each setup before choosing.

A three-unit mesh kit to consider when more than one room needs coverage.
The listing specifies a dual-band BE3600 system with a 2.5Gbps WAN and LAN port on the router and a 2.5Gbps LAN port on each satellite. An existing modem or gateway is required, and stated coverage and wireless speed vary with network and building conditions.
No image available
A local extension option to consider where the existing router signal remains usable, or where an Ethernet feed can serve an access-point setup.
The listing specifies EasyMesh compatibility, access-point mode and a 1Gbps Ethernet port. For range-extender mode, it advises placing the unit within range of the existing router’s signal.
No image available
A three-unit mesh option to consider when coverage is needed across several rooms.
The listing describes wired and wireless backhaul and two 1Gbps Ethernet ports per unit. TP-Link’s Deco guidance says the main unit must connect to the existing router, modem or internet cable by Ethernet.
No image available
A single-router option to consider when checks suggest the existing router is the limitation and the ISP setup is compatible.
The listing specifies a 2.5Gbps WAN/LAN port, two Gigabit LAN ports and EasyMesh support. Its 5G internet option requires a SIM card; compatible additional equipment is needed for mesh expansion.
No image available
A single-router option to consider when refreshing a router, with the possibility of adding compatible equipment if coverage needs change.
The listing specifies a 2.5-Gigabit WAN port and three 2.5-Gigabit LAN ports. Mesh expansion requires compatible AQUILA PRO AI routers or extenders, which are not identified as part of this router listing.
Compare the connection near the router with the upstairs result, and where possible test a computer directly connected by Ethernet. If it is poor near the router as well, check with your provider; if the problem is mainly upstairs, examine router placement and in-home coverage. Ofcom cautions that one test does not isolate every possible cause.
It depends on the system, so check the instructions for the exact model. TP-Link says the main Deco unit must connect to the existing router, modem or internet feed by Ethernet, while its satellite units can connect within the Deco network.
Check the wiring requirements and which network features remain available in the selected mode. TP-Link documents different wiring rules for Deco router and access-point modes; eero says bridge mode needs one wired eero and disables some advanced network features.
Only if the mesh unit also has a wired route back through the network. eero notes that a device connected by Ethernet to a wireless eero still communicates onward over Wi-Fi, so check the unit’s backhaul as well as its Ethernet ports.
No; replacing one router may not overcome the floors or walls between it and the work room, and it will not fix a fault with the broadband service reaching the home. Compare the connection near the current router with the upstairs result, and check your ISP’s setup requirements before choosing a replacement.
