If Wi-Fi works near the router but weakens upstairs, compare those locations before changing your broadband package. An Ethernet-fed access point or mesh node is worth considering where cabling reaches the weak area; for several rooms, consider mesh, while a wireless extender needs a usable signal at its own location and powerline depends on the home’s electrical wiring. Replacing the ISP router is a separate decision that requires checking your plan and connection.
If the connection is usable near the router but poor in a bedroom, office or extension, check the router’s position and compare the signal in each location. Ofcom notes that Wi-Fi weakens as it passes through objects.
If phones and laptops move between floors and several areas need coverage, a multi-node mesh system may be more relevant than extending one room. Check how its nodes connect: TP-Link says Ethernet backhaul can provide a faster, more reliable link between its Deco units than wireless backhaul.
A wireless extender, mesh nodes or a powerline Wi-Fi kit may be practical to consider, but each needs a workable connection back towards the router. For powerline, TP-Link specifies electrical-circuit and socket conditions that should be checked in the home.
Establish where the connection weakens, then choose how a new Wi-Fi point will connect back to the router.
| Priority | What to check | Your needs |
|---|---|---|
| Locate the weak link | Compare Wi-Fi near the router with the affected room; use a wired connection as a reference if available. Check whether moving the router improves the path through walls and floors. | Wi-Fi works near my router, but I need a usable connection upstairs. Ofcom’s guidance notes that objects between a device and router can weaken the signal. |
| Ethernet route | Check whether a cable can reach the weak room or a mesh-node position, and whether the chosen device supports the intended access-point or backhaul setup. TP-Link documents these options for specific RE and Deco models. | I can run a cable to the room and would rather use it to feed a new Wi-Fi point than depend on a weak wireless link. |
| Rooms and roaming | Identify how many areas need coverage and where mesh nodes could receive a usable connection. Confirm the exact system’s operating mode when keeping an ISP router. | We move between several rooms with phones and laptops, so I want to consider a network designed to cover more than one isolated dead zone. |
| Wireless relay | Find a position between the router and the weak area where an extender still receives a usable signal. Check router compatibility before relying on model-specific mesh roaming. | Only one nearby room needs help, and there is a suitable place for an extender before the signal drops away. |
| Powerline path | Check the electrical relationship between the two socket locations and use direct wall sockets. TP-Link warns that power strips and surge protectors can filter or block a powerline signal. | Running Ethernet is impractical and Wi-Fi struggles through the walls or floor; I can test whether the home’s wiring offers another path. |
| ISP compatibility | Before replacing a router, confirm your plan, connection method, credentials and any voice-service requirements. Vodafone says its Pro Broadband, 5G Broadband and Digital Voice plans require a Vodafone router. | I want to keep my broadband and voice services working while improving coverage, rather than assuming a new router can replace the supplied one. |
| Ongoing support | Check the exact model’s firmware-update instructions and support information, and set a unique administrator password during setup. | I want a device I can keep updated after it is installed, not just one that reaches the weak room. |
A different standalone router still has to send Wi-Fi through the same walls and floors. Ofcom notes that objects can weaken the signal, so a router change alone should not be assumed to reach the affected room.
Compare the connection near the router and upstairs, and try a different router position before choosing an expansion device.
An extender or wireless mesh satellite needs a usable connection back towards the main router; placing it where that connection is already weak carries the problem into the new Wi-Fi point.
Try a position between the router and weak room. If that cannot provide a usable link, consider Ethernet backhaul, a wired access point or powerline where the electrical conditions permit.
The rating does not establish what a kit will achieve over a particular home’s wiring. TP-Link says its adapters need an appropriate electrical connection and warns that power strips or surge protectors can obstruct the signal.
Use direct wall sockets, check the circuit arrangement and test the kit in the intended rooms.
Router replacement can affect how the broadband and voice services connect. Vodafone, for example, requires its router on specified Pro Broadband, 5G Broadband and Digital Voice plans.
Check your exact provider plan and equipment requirements. If the aim is Wi-Fi coverage, also consider a mesh system connected to the existing router in a supported access-point mode.
TP-Link has model ranges spanning Deco mesh, Archer routers, RE extenders and powerline Wi-Fi kits.
Amazon presents eero as an app-guided mesh range.
NETGEAR offers Orbi mesh systems as well as standalone extenders.
ASUS’s AiMesh route is relevant to households considering compatible routers or nodes.
These options include multi-room mesh systems, a powerline Wi-Fi kit for a room where cabling is difficult, and an extender for a nearby weak area. Choose the connection route before comparing individual models.

Consider this three-unit mesh system when several areas need Wi-Fi coverage. The named variant is dual-band BE3600 with 2.5Gbps Ethernet; check how it connects to your ISP equipment and where its units can be placed.

A three-unit mesh option to consider for several weak rooms. Check the BE22’s connection and operating-mode instructions against your existing router, and plan positions that give the units a usable link.

This three-pack is another mesh option for coverage across multiple rooms or floors. Confirm how the BE65 units will connect to one another and to your ISP router; the stated Wi-Fi specification does not predict coverage through your walls.

Consider a powerline Wi-Fi kit when running Ethernet is impractical and the wireless path to the room is poor. TP-Link says powerline adapters need an appropriate electrical-circuit connection; use direct wall sockets and test the kit in the intended locations. AV1300 is a product rating, not a guaranteed room-to-room speed.

An extender is a route to consider for one nearby weak area if you can place it where the router signal remains usable. Check compatibility with your exact router before relying on shared-network or roaming features.
Not automatically. Compare the connection near the router, or over Ethernet if possible, with Wi-Fi in the weak room. If it works well near the router but poorly upstairs, investigate in-home coverage first; Ofcom notes that objects between a router and device can weaken Wi-Fi.
It may: TP-Link documents connecting Deco to an existing router in router or access-point mode. The main unit needs the connection specified for that system, so check your exact mesh model and ISP equipment before changing network settings.
Consider a wired access point when Ethernet reaches the weak room: it receives its network connection through the cable rather than relaying Wi-Fi from the router. A wireless extender instead needs a usable router signal where you place it.
No. TP-Link says its powerline adapters need a suitable electrical-circuit connection and warns that power strips and surge protectors can filter or block the signal. Check the socket locations and test the kit in the rooms where it will be used.
It depends on the plan. Vodafone says its Pro Broadband, 5G Broadband and Digital Voice plans require a Vodafone router; for other plans, it specifies requirements for a non-Vodafone router and broadband credentials. Check your exact plan before removing the supplied equipment.
