If Ethernet can reach the upper floors, consider wired access points or mesh with wired backhaul for a household using several devices at once. Where cabling is impractical, wireless mesh can cover several areas; a powerline kit depends on the home’s wiring, while a single extender is more suited to a limited weak spot where it can still receive a usable router signal. If you are keeping an ISP router, check the chosen equipment’s connection and operating-mode requirements before buying.
If upstairs rooms are used for streaming, work, study or connected devices, look beyond whether a Wi-Fi signal appears at all. Ofcom advises checking whether other people are using the connection for data-hungry tasks; the link between floors matters when choosing where to add coverage.
An existing cable run makes a wired access point or wired-backhaul mesh worth considering. TP-Link describes Ethernet backhaul for its Deco systems as a way to connect units without relying on a wireless link between them; check support on the exact equipment you choose.
If the broadband router needs to remain in place, check how the added equipment connects to it and whether it offers a suitable access-point mode. TP-Link documents both Router and Access Point modes for Deco with an existing router, but setup requirements and available functions depend on the mode.
Start with the rooms that need coverage, then check whether a cable, a usable wireless link or suitable mains sockets can connect them back to the router.
| Priority | What to check | Your needs |
|---|---|---|
| Upper-floor reach | Check where the router sits, which floors and rooms are weak, and where another unit could receive a usable connection. Ofcom notes that objects and building materials weaken Wi-Fi signals. | I need Wi-Fi in an upstairs bedroom or office, not just beside the router. If walls and floors obstruct the signal, moving the router or adding equipment may change which route is practical. |
| Backhaul | Check for an Ethernet run to the upper floor before choosing wireless mesh or a wired access point. For TP-Link EasyMesh Ethernet backhaul, TP-Link says both the main and satellite devices must support that feature. | Several people may stream or work at once, so I want to know how an upstairs unit connects back to the router—not merely whether it broadcasts Wi-Fi. |
| Movement between floors | Check whether the exact system offers coordinated mesh roaming or whether an extender creates a separate network. NETGEAR describes these as differing approaches, but extender behaviour depends on the model and setup. | Phones and laptops move around the house; I would rather not have to change networks manually between floors. |
| Powerline conditions | Check the intended sockets and the kit’s installation guidance. NETGEAR advises using adapters on the same electrical circuit and plugging them directly into wall outlets. | Running Ethernet through the house is impractical, but I can test whether the intended upstairs socket works for a powerline Wi-Fi kit. |
| ISP-router setup | Check the main unit’s required connection, supported Router and Access Point modes, and which device will handle gateway duties. Do not assume a mesh unit can wirelessly repeat the ISP router. | I want to keep my existing broadband router and add coverage without choosing equipment that needs a different connection or network setup. |
An extender needs a usable connection to the router before it can rebroadcast Wi-Fi. NETGEAR and BT advise placing their extension equipment roughly halfway towards the weak area, rather than at its far edge.
Try a suitable location between the router and the weak room. If no such position has a usable signal, consider a wired access point or another route instead.
The main unit may need an Ethernet connection to the existing router. TP-Link’s Deco guidance distinguishes Router and Access Point modes, which have different setup requirements.
Check the exact system’s main-unit connection and operating modes, then decide which device should retain the router role before installation.
The home’s electrical installation affects whether powerline is suitable for the intended sockets. NETGEAR’s guidance calls for adapters on the same circuit and direct wall-outlet connections.
Check the socket arrangement and test the kit in the rooms where it will be used. Confirm the retailer’s applicable return terms before purchase without assuming that every home will give the same result.
Another wireless node still needs a usable link to the rest of the network. Ofcom notes that obstacles weaken Wi-Fi, while TP-Link describes Ethernet backhaul as an alternative connection between supported units.
Map the weak rooms and possible node positions first, and check for usable Ethernet runs before deciding how many units to place across the floors.
Its Deco mesh systems and EasyMesh-compatible equipment are relevant when comparing wireless coverage, Ethernet backhaul and use with an existing router.
Its Orbi mesh, extender and powerline ranges illustrate different ways to reach rooms away from the router.
BT Complete Wi-Fi discs are a provider-specific option to consider if the household uses a compatible BT Hub.
These options cover three-unit mesh systems for coverage across several areas and a powerline Wi-Fi kit for a location where running Ethernet is impractical. Check each model against your router and home layout; this list does not include a wired access point or a standalone extender.

A three-unit mesh option to consider when more than one floor needs coverage. Check this exact model’s required connection, operating mode and backhaul options if you will keep an ISP router or connect units by Ethernet; coverage in your home depends on placement and construction.
No image available
This three-unit mesh system is an option for rooms spread across several floors. Its name specifies dual-band WiFi 7 and 2.5Gbps Ethernet; check the exact system’s ISP-router setup and whether it supports Ethernet backhaul before planning a wired link between units.

The three-pack format is relevant when coverage is needed in several rooms or on different floors. Confirm this exact model’s operating mode with your ISP router and its Ethernet-backhaul support if you intend to wire the units together.

This powerline Wi-Fi kit is an alternative to running a long Ethernet cable to an upstairs room. Check the intended sockets against the installation guidance; NETGEAR’s powerline guidance recommends the same electrical circuit and direct wall outlets. If roaming through OneMesh matters, confirm that your router is compatible.

This three-pack mesh system is worth considering when you plan units for more than one part of the home. Confirm its backhaul options, main-unit connection and operating mode for your ISP-router setup before deciding where each unit will go.
If Ethernet reaches the upper floor, wired access points or mesh with supported Ethernet backhaul avoid relying on a wireless link between floors. TP-Link describes that advantage for its supported backhaul equipment. Wireless mesh is an option when cabling is impractical, provided the nodes can be placed where their links remain usable.
You may be able to, but check the exact system’s connection and operating modes. TP-Link documents Deco in Router or Access Point mode with an existing router; the main Deco needs an Ethernet connection, and Access Point mode leaves gateway duties with the existing router. Follow the chosen model’s topology instructions.
Place it where it can still receive a usable router signal, rather than inside the dead zone. NETGEAR recommends a position roughly halfway between the router and weak area; check the signal at the intended position before relying on an extender for that floor.
Consider one when running Ethernet is impractical and a wireless link struggles to reach the room. Check the intended sockets first: NETGEAR advises using adapters on the same electrical circuit and plugging them directly into wall outlets. Results depend on the home’s electrical installation.
Not necessarily. NETGEAR describes mesh as coordinated nodes on one network, while a conventional extender may use a separate network name. Check the exact extender’s roaming or mesh compatibility if moving between floors without manually changing networks matters to you.
