Check the broadband connection before buying equipment: as Ofcom explains, better Wi-Fi cannot make the underlying service faster or repair a provider fault. If the service works well near the router, a provider upgrade or replacement router may suit a home where one well-placed point can reach the needed rooms. For weak rooms beyond thick walls or on several floors, consider mesh nodes; use Ethernet-backed mesh or wired access points where a wireless link between nodes would also be weak.
If Wi-Fi works near the router but becomes unreliable beyond internal walls or floors, extending coverage may matter more than changing the broadband service. Ofcom notes that brick internal walls can make whole-home Wi-Fi difficult.
An existing cable run, or one you are willing to install, gives a remote mesh node or access point a wired connection back to the network. TP-Link and eero describe Ethernet backhaul as an alternative to a wireless link between nodes.
If your connection uses an optical network terminal (ONT), check how the new router will connect and which settings your provider requires. Keeping the provider router and adding Wi-Fi points may avoid replacing its routing role.
Once the broadband service is working adequately, decide whether one router can realistically reach the weak rooms or whether they need additional Wi-Fi points. Then check whether those points can connect reliably over Wi-Fi or need Ethernet.
Consider it: When you want the provider to remain your first point of support and prefer to keep the existing broadband setup.
Trade-off: Available equipment depends on the provider, and a single replacement router may still struggle beyond brick walls.
Consider it: When one suitably placed router could cover the home and you need particular LAN connections or router controls.
Trade-off: You must confirm the provider’s WAN requirements and may need to handle setup and equipment troubleshooting yourself.
Consider it: When several rooms or floors need Wi-Fi points and the nodes can form a usable path back to the main router.
Trade-off: Thick walls can also weaken the links between wireless nodes; bridge or access-point mode may limit some network features.
Consider it: When Ethernet reaches a weak area, or a cable can bypass walls and floors that obstruct wireless links.
Trade-off: Plan the cable route and check whether the chosen access point also needs Power over Ethernet equipment.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across walls and floors | Map the weak rooms and possible router or node positions. Check whether a mesh system can place nodes along a usable connection path. | If I lose Wi-Fi as soon as I move upstairs or behind brick walls, I need the signal to reach those rooms rather than just the room with the router. Around 31% of consumers put coverage across barriers first. |
| Stable connection in a remote room | Check Ethernet backhaul support, the permitted wiring layout and any cable or Power over Ethernet requirements. | For calls, streaming or gaming in a distant room, I need the connection between Wi-Fi points to remain dependable. Around 19% of consumers place that consistency first. |
| Simple setup and support | Ask what equipment and support the provider offers. If retaining its router, check the added system’s access-point or bridge mode. | I would rather keep my current broadband setup than take on router configuration and troubleshooting. Around 25% of consumers prioritise straightforward setup and support. |
| ISP and full-fibre compatibility | Confirm the WAN connection type and provider settings, plus any voice service that depends on provider equipment. | If I replace the router on a full-fibre connection, I need internet access and existing services to keep working. Around 25% of consumers make compatibility and control their primary concern. |
Ofcom distinguishes problems with the broadband service from problems with Wi-Fi inside the home. A new router or mesh system will not repair an outage or make the service itself faster.
Check service status and the connection close to the router. Restart relevant equipment and report a continuing service problem to the provider before choosing a coverage solution.
Ofcom notes that brick internal walls make whole-home coverage harder. If the difficult rooms remain separated from a central router by several barriers, replacing that single Wi-Fi point may not address the layout.
Identify where coverage drops and where another node or access point could sit. Consider multiple points rather than judging a router by its stated coverage area alone.
A node needs a usable connection back to the network, not merely a convenient position in the dead zone. TP-Link and eero describe Ethernet backhaul as a way to avoid relying on that wireless link.
If the path between nodes crosses the difficult walls or floors, check whether the chosen system supports your intended Ethernet wiring layout.
A wired layout may also call for cabling or suitable network and power equipment.
ASUS advises checking the ISP’s WAN connection type before configuring a third-party router. Changing routing equipment can also affect how existing network features are set up.
Confirm provider settings and any voice service that depends on its equipment. If you only need wider Wi-Fi coverage, compare keeping the router and adding mesh or access points.
Allow time to configure the replacement and resolve any affected network settings.
A mesh range to consider when several Wi-Fi points are needed, including layouts that can use Ethernet between nodes.
A mesh option for households considering wired node connections or keeping an existing router.
A third-party router route when the provider connection requirements and the particular router’s capabilities are known.
A wired-access-point route for homes prepared to bring Ethernet to a weak area.
Check the service first, then compare the connection near the router with the weak rooms. Ofcom explains that Wi-Fi cannot outperform the underlying broadband service: check for an outage and contact the provider about a continuing fault. If the connection works well near the router but deteriorates beyond walls or upstairs, in-home coverage is the more plausible issue.
No: for an Openreach FTTP installation, Openreach says the ONT and its power supply must remain in place. The router connects to the ONT by Ethernet; confirm the applicable port and your provider’s WAN settings before changing routers.
Use access-point or bridge mode if you intend to keep the existing router in charge of routing, but check which features the mesh system loses in that mode. TP-Link documents unavailable functions in Deco access-point mode, and eero documents feature limits in bridge mode. If the mesh system will replace the router’s role, confirm your provider connection settings first.
