Check the broadband connection at the main router by Ethernet before buying equipment for upstairs: as Ofcom explains, Wi-Fi cannot outperform the broadband service feeding it. If that connection is sound, try a better router position; choose a wired access point or Ethernet-connected mesh where you can run cable, wireless mesh where you cannot, or powerline if the intended sockets provide a usable connection.
If Wi-Fi works near the router but drops in a bedroom, loft room or upper-floor workspace, start by checking the router position and where an additional node could still receive a signal. Ofcom notes that building materials and electrical interference can affect Wi-Fi inside the home.
When several people stream, work or make video calls and Ethernet can reach an upstairs position, a wired access point or Ethernet-connected mesh node offers a way to carry the node connection by cable. Check the equipment’s supported wiring layout before installation; TP-Link documents different arrangements for its Deco operating modes.
If thick walls or several floors obstruct a wireless link, powerline is another route to consider. It uses household electrical wiring, but devolo’s guidance calls for direct wall sockets and acknowledges that transfer rates can be low at some outlets. Test it where the adapters would actually sit.
Separate a slow broadband connection from a weak upstairs Wi-Fi signal first. Then choose according to the cable route, node position or wall sockets available in your home.
| Concern | Buying checks | Who this matters to |
|---|---|---|
| Broadband or Wi-Fi? | Test by Ethernet at the main router and compare the result with an upstairs Wi-Fi test at a similar time. Check the wired result against the service level in your contract. | If streaming is slow even near the router, I need to rule out the broadband connection before changing upstairs equipment; about 29% of consumers put that diagnosis first. |
| A cabled upstairs link | Check whether Ethernet can reach a useful upstairs position and whether the chosen access point or mesh system supports the intended ports, operating mode and wiring layout. | When several people stream or join video calls upstairs, I want a cable to carry the connection to the upstairs Wi-Fi point; about 36% of consumers prioritise that cabled link. |
| Wireless coverage | Check the number of mesh units and the maker’s placement guidance. Plan a position between the router and the dead zone where a node can still receive a signal. | I cannot run Ethernet, but laptops and streaming still need Wi-Fi in the upper rooms; for about 21% of consumers, coverage without new cabling is the primary need. |
| Mains-wiring route | Choose an upstairs adapter with Wi-Fi if you need wireless coverage, rather than LAN alone. Confirm that both intended locations have usable direct wall sockets and test the link there. | If walls obstruct Wi-Fi and cable routing is impractical, I need to find out whether the upstairs socket can carry the connection; about 14% of consumers put mains-based connectivity first. |
A new Wi-Fi network cannot fix a broadband connection that is already slow at the router. Ofcom recommends a wired connection when checking broadband speed, because a Wi-Fi test can reflect limitations inside the home.
Test by Ethernet at the router and compare the result with your contracted service level. If wired results remain poor, ask your provider to investigate before choosing coverage equipment.
A node also needs a connection back to the network. BT’s placement guidance notes that walls, electrical equipment and interference affect disc range.
Start approximately halfway towards the upstairs room, as BT advises for its discs, then adjust the position using the chosen system’s guidance and a test in the room.
Ports and supported connections depend on the exact product and operating mode. TP-Link specifies different Deco wiring arrangements in router and access-point modes and warns that incorrect router-mode wiring can create a network loop.
Check the model’s Ethernet-backhaul instructions, required ports and operating mode against your ISP hub and proposed cable route before buying.
The connection depends on the electrical environment at the intended sockets. devolo notes that some outlets can have low transfer rates and advises against connecting adapters through extension leads or power strips.
Plug the adapters directly into wall sockets and test the connection in the two locations where you need to use them.
Whole-home mesh systems to consider when adding wireless nodes, with Ethernet-connected nodes available in supported configurations.
Wi-Fi disc ranges with placement guidance for extending coverage into distant rooms.
Powerline products to consider when a dedicated Ethernet run is impractical; the upstairs adapter’s LAN and Wi-Fi functions depend on the variant.
An access-point range to assess when Ethernet can reach the desired Wi-Fi location and the household is prepared to check setup requirements.
These products cover multi-unit mesh Wi-Fi for rooms across the home and a powerline Wi-Fi kit for trying a connection through mains wiring. Choose the route only after checking the router connection and what your layout allows.

Consider this three-unit mesh system when Wi-Fi is needed in several rooms or on more than one floor. If you plan to connect nodes by Ethernet or retain an ISP hub, check this exact variant’s supported wiring and operating modes before buying; the room layout will still determine useful node positions.

This three-pack mesh system is an option for placing Wi-Fi units across several rooms. Its product name specifies dual-band operation and 2.5Gbps Ethernet; check which connections suit your intended devices, and confirm Ethernet-backhaul and ISP-hub arrangements if either is part of your plan.

Consider this three-unit mesh system if several rooms need Wi-Fi coverage and its supported setup fits the home. The product name identifies a tri-band Wi-Fi 7 variant; check the exact model’s Ethernet-backhaul instructions and router or access-point mode before planning a wired installation.

This three-pack mesh system is relevant when a single router does not reach all the rooms that need Wi-Fi. Check the BE25 variant’s port arrangement, supported Ethernet wiring and operating mode against your ISP hub if you intend to use a cable upstairs.

Consider this powerline Wi-Fi kit when running Ethernet upstairs is impractical and you have direct wall sockets at both intended locations. Test the connection in those sockets rather than relying on the AV1300 rating; if you want to use OneMesh with an existing router, confirm compatibility with that exact router.
Test a computer or tablet connected to the main router by Ethernet, then compare it with Wi-Fi in the upstairs room. Ofcom advises using a wired connection to assess broadband speed: if that result remains below the service level in your contract, ask your provider to investigate; if the wired result is sound but upstairs Wi-Fi is poor, examine placement, obstructions and local coverage.
Put a wireless node where it can still connect to the existing network, rather than only in the room where reception has failed. BT suggests starting approximately halfway towards the coverage area for its discs, then adjusting the position for walls, electrical equipment and the results you get upstairs.
You can keep an existing router with a mesh system that supports a suitable arrangement, but check both exact models. TP-Link documents router and access-point modes for Deco; Virgin Media documents modem mode for Hub 3, 4 and 5, but says it is unavailable for Hub 5x and disables several Hub features where used. Other provider hubs may offer different options.
Prioritise an Ethernet-connected access point or compatible mesh node when a cable can reach a useful upstairs position, particularly if several people regularly stream or make video calls. The cable carries the link to that Wi-Fi point, but you still need to check the chosen equipment’s ports, power requirements and supported wiring layout.
Powerline is worth testing when cable routing is impractical, but it does not guarantee a usable connection at every socket. Choose a Wi-Fi-equipped upstairs adapter if you need wireless coverage, connect the adapters directly to wall sockets as devolo advises, and test the two locations you intend to use.
