First check that the upstairs device needs an RJ45 Ethernet connection and that the router has a free LAN port; the ONT-to-router connection serves a different purpose. If a discreet cable route is practical, it gives you a direct wired path. Otherwise, compare powerline adapters with a mesh node or bridge that can receive a usable Wi-Fi signal upstairs; an Ethernet socket on a wireless node does not make the connection between floors wired.
If your upstairs streamer, PC or other fixed device needs Ethernet, but you do not want a cable across the stairs, compare powerline and wireless options and check the connection at the device. A UK household raised this kind of upstairs streamer setup on MoneySavingExpert Forum.
If you can use an existing data point or route cable discreetly, a direct connection may suit your preference better than relying on mains wiring or a wireless link. Ofcom advises using Ethernet between a computer and router for a faster, more reliable connection than Wi-Fi.
If you also want to improve Wi-Fi in several rooms, check the placement and Ethernet ports of the exact mesh units you are considering. TP-Link lists Ethernet ports and wireless or optional Ethernet backhaul for its Deco X50 V2.
For a household connecting one fixed upstairs Ethernet-only device after the router location changes, decide how you will carry the connection between floors before choosing the equipment.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Avoiding a visible cable | Check whether powerline adapters or a wireless node can reach the upstairs position, and confirm the device-side Ethernet port. | I need to connect an upstairs streamer or PC without a cable across the stairs; around 36% of consumers put avoiding a visible inter-floor run first. |
| A direct wired path | Look for an existing data point or measure the full route from a router LAN port to the device, including the cable path and finishing work. | If I would rather plan a discreet cable route than depend on mains wiring or Wi-Fi between floors, I prioritise a direct connection; around 29% of consumers do the same. |
| Ethernet plus wider Wi-Fi coverage | Check that the upstairs mesh unit has an Ethernet port and can be placed where it receives a usable link; establish whether backhaul is wireless or cabled. | When I need an upstairs wired device and have a separate reason to improve Wi-Fi in other rooms, both needs matter; around 21% of consumers prioritise this combination. |
| Equipment for one device | Compare a bridge or Ethernet-equipped extender with a two-adapter powerline kit; check port speed, socket position and the required connection mode. | If my only priority is connecting one upstairs device, I would compare focused options before buying a multi-node kit; around 14% of consumers put this narrower setup first. |
A device can connect to its upstairs node by Ethernet while the node still communicates with the downstairs network over Wi-Fi.
Check what carries data between floors and confirm that the exact upstairs unit has an Ethernet port.
Powerline performance can vary with network conditions, socket choice and electrical interference.
Test the intended sockets with the device connected, and check adapter-family compatibility if you are adding to an existing set.
A product's wireless speed-class label does not tell you the speed of its wired port. NETGEAR lists a 10/100 Mbps Ethernet port on the EX6120.
Check the port specification on the exact model against the fixed device's requirements.
A stated cable length and RJ45 ends do not show whether it will reach discreetly or create a finished wall data point.
Measure the route, inspect existing data points and plan the cable management before selecting a length.
Cable-management materials or installation work may also be needed for a discreet route.
Relevant product lines include powerline adapters and mesh systems with Ethernet ports.
The Magic 2 LAN Starter Kit is a powerline option for connecting a room without running an inter-floor data cable.
The EX6120 is a wireless extender with an Ethernet port for connecting a wired device to Wi-Fi.
The RT-AX57 Go lists Media Bridge mode and a Gigabit LAN port for a wireless-bridge approach.
Its listed 20 m Cat6 RJ45 patch lead is an example of a direct-cable option.
These choices cover a powerline kit and a mesh system with Ethernet ports for connecting an upstairs device. If a mesh satellite connects wirelessly, the link between floors still depends on Wi-Fi.

Consider this powerline kit if you want to connect an upstairs wired device without running a cable between rooms, provided the intended sockets work well together.
The product description identifies a two-adapter kit; the title specifies Gigabit Ethernet and a passthrough power socket.

Consider this mesh system if you need an Ethernet connection at an upstairs satellite and also want a mesh setup for the home; check that the planned satellite position receives a usable link.
The product description lists one router and two satellites, with a 2.5Gbps LAN port on each satellite. It also specifies a dual-band Wi-Fi 7 system.
For this device-extension setup, identify an available LAN port on the provider's router. Openreach describes the ONT as connecting to the provider router, so do not treat the ONT-to-router connection as a spare router LAN port; check the ports on your installed equipment.
Pair the adapters as instructed, then test them in the actual downstairs and upstairs sockets with the device connected. devolo recommends plugging adapters directly into wall sockets rather than extension leads and notes that electrical interference can affect transmission.
Ofcom advises reporting a broadband service fault to your provider, even if another company owns the network. For additional internal wiring, establish who will install and support it; Openreach's home-wiring guidance describes options but does not establish what a provider will install in a particular existing home.
There is no blanket UKCA-only conclusion for every UK destination. UK Department for Business and Trade guidance published in March 2026 lists UKCA or CE for radio equipment placed on the Great Britain market; for Northern Ireland, it lists CE, or UKNI together with CE, under the applicable assessment route. This guidance does not establish the status of a particular product, so check the exact product and destination.
