Start by checking whether the weak connection is limited to upstairs Wi-Fi, then try a more central router position if your provider connection allows it. A single router may suit one weak area; wireless mesh is worth considering for several rooms if its nodes can maintain a usable link, while an Ethernet-connected access point or mesh node is a practical route where a cable can reach upstairs. Keep an Openreach Full Fibre optical network terminal (ONT) in place, and check provider and voice-service requirements before replacing a supplied router.
If broadband works near the router but a bedroom or office has poor Wi-Fi, check the router’s position and obstacles before adding several devices. Ofcom notes that objects and building materials can weaken the signal.
When weak spots occur across floors, compare a mesh layout with additional access points rather than assuming one router will reach every room. Nodes still need a workable connection to one another, whether wireless or wired.
An existing outlet or feasible cable run gives you the option of a wired access point or wired mesh backhaul. TP-Link and eero document Ethernet connections between compatible mesh units; check the ports and wiring arrangement for the exact equipment you choose.
Choose the network layout before comparing Wi-Fi labels: the number of weak rooms, obstacles between floors and any usable Ethernet route determine which equipment is worth considering. An Ethernet switch can add wired connections alongside these options, but it does not extend Wi-Fi on its own.
Consider when: One area is weak and the router can be moved to a more central, open position, or a compatible replacement is being considered.
Trade-off: Walls and floor construction may still prevent a single router from reaching upstairs; replacing a supplied router also requires provider-specific checks.
Consider when: Several rooms are weak, Ethernet is impractical and you can place nodes where they can communicate reliably.
Trade-off: A wireless connection between nodes remains affected by distance and building materials, so advertised coverage cannot settle placement in your home.
Consider when: Ethernet already reaches upstairs or a cable run is feasible, particularly across thick walls or several floors.
Trade-off: The cable, ports and device mode must fit the network layout; ASUS says its access-point mode disables routing on the secondary device.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage through floors and walls | Map the weak rooms and obstacles, then test whether a more central router position helps. For mesh, identify positions where nodes can still connect. | If an upstairs bedroom stays weak while nearby rooms work, I need the signal to reach through my home’s particular layout. Around 36% of consumers put coverage through floors and walls first. |
| Stable upstairs connections | Look for a usable Ethernet outlet or cable route, and check whether the chosen access point or mesh units support the intended wired connection. | For work, gaming or streaming upstairs, I would rather use an available cable than depend on a weak link between floors; roughly 29% of consumers prioritise that wired stability. |
| Provider-equipment compatibility | Identify the provider router, ONT connection and any provider-delivered voice service before changing router or access-point mode. | If my supplied router handles services I still need, I want better Wi-Fi without disrupting them. About 21% of consumers make continuity of their provider setup the primary concern. |
| Wired ports for fixed devices | Count the required LAN connections and check the ports on the exact devices. Plan any switch on the appropriate LAN side of the network. | When fixed devices and an upstairs Wi-Fi point need cables, I need enough usable connections; around 14% of consumers put port expansion first. |
A poor wireless link within the home can affect upstairs use even when the connection near the router works. Ofcom also notes that Wi-Fi cannot exceed the underlying broadband service.
Compare use near the router with the weak room, check for heavy household usage or outages, and identify which part of the connection is failing before buying equipment.
For Openreach Full Fibre, the ONT is the connection point between the fibre network and the home, not the Wi-Fi router.
Leave the ONT and its power supply in place. Check how your router connects to it and what your provider requires before replacing or bypassing the supplied router.
An available cable can connect an access point or compatible mesh node without relying on a wireless link between floors.
Inspect existing RJ45 outlets and feasible cable paths before choosing between wireless mesh, wired mesh and an access point.
Router mode and access-point mode can require different connections. TP-Link’s Deco guidance calls for the main unit to have a physical Ethernet connection to the existing network.
Follow the wiring diagram for the exact model and mode rather than connecting every unit to the existing router by assumption.
Deco is TP-Link’s mesh line for layouts using wireless or Ethernet-connected nodes.
eero is a mesh option where some nodes may be connected by Ethernet and others wirelessly.
ASUS routers and AiMesh are relevant when considering a secondary wired access point or compatible mesh arrangement.
Orbi is NETGEAR’s mesh line to consider when comparing node placement and available cable routes.
This range extender is an add-on to consider for a weak area when the existing router can still provide a usable signal at the extender’s intended position. It is not a replacement for the router or an Ethernet-connected upstairs access point.

Consider this for a weak upstairs area if you can position the extender where it still receives the existing router’s signal. Check the connection at that position and in the room you want to use; walls and floors can affect the result.
Compare the connection near the router with the experience upstairs: a problem concentrated in the distant room points towards the in-home Wi-Fi link, though it does not identify a particular equipment fix. Ofcom advises checking household usage, restarting relevant equipment and checking for provider outages before assuming a new device is needed.
For Openreach Full Fibre, keep the ONT in place: Openreach identifies it as the connection point between the fibre network and your home, not as the Wi-Fi router. Check your network operator and provider requirements before changing the router connected to it.
Yes, where the chosen system supports a suitable connection and mode with the existing router. TP-Link documents Deco access-point and router-mode setups with a physically connected main unit; check the exact model’s wiring instructions and any provider voice-service requirements before changing your setup.
