Check whether the connection is poor near the router as well as in distant rooms: as Ofcom explains, Wi-Fi cannot outperform the broadband service feeding it. Try router placement and basic fault checks before buying equipment. An extender is worth considering for one weak area that still has a usable signal nearby; persistent weak rooms across several floors or behind solid walls may call for mesh, while an ageing router or an inadequate incoming connection needs a different fix.
If the signal struggles across floors or through substantial internal walls, test router placement first. If several rooms remain weak, consider coverage from multiple mesh nodes rather than assuming one extender will reach them all.
When calls, streaming or downloads falter during simultaneous use, compare performance near the router with performance elsewhere. That helps separate a possible broadband or router limitation from weak coverage in particular rooms.
If most rooms work well and there is still a usable signal between the router and the weak area, an extender may address that location without replacing the whole network.
Start with the incoming connection and router position, then choose equipment according to where the signal fails and how you use it.
| Priority | What to check | Your needs |
|---|---|---|
| Broadband connection | Compare performance near the router with affected rooms. Check for an outage and whether heavy simultaneous use coincides with slowdowns. Ofcom notes that Wi-Fi cannot outperform the broadband service. | If it is slow even close to the router, I want to investigate the service or household demand before buying coverage equipment. |
| Router position | Try a central position off the floor where practical, away from major obstructions. Retest the rooms that cause trouble before choosing hardware. | My router sits at one end of the home, and I want to see whether moving it improves the distant rooms. |
| One weak area | Check for a usable signal at a point between the router and the weak room. An extender placed inside a dead zone has too little signal to repeat; check compatibility if coordinated roaming matters. | Most rooms work, but I need a connection in one bedroom or another reachable area. |
| Several weak rooms | Map the affected floors and walls. For mesh, check the number of nodes, possible positions and whether the nodes can use wired or wireless connections to one another; coverage claims are not guarantees for your layout. | I move between rooms during calls, or several rooms remain weak after I have repositioned the router. |
| Existing router | Check whether an older router is limiting connections even near it. Before replacing provider equipment, confirm the broadband connection type and any provider-specific services. | I need to improve an ageing router, but I do not want to assume a new single router will reach through every wall. |
A router, extender or mesh kit cannot overcome a slow incoming broadband connection. Ofcom advises checking broadband and Wi-Fi problems before moving to equipment changes.
Compare a device near the router with one in the weak room, rule out an outage and consider whether simultaneous activity is affecting the connection. If the service appears limiting, check the broadband options at your postcode.
An extender needs a usable signal from the router before it can pass that connection on. Walls and other obstacles can weaken the link to the extender itself.
Place it between the router and the weak area, then adjust its position using its signal indicator or setup guidance.
A replacement router still broadcasts from one position. Multiple floors or obstructing walls can leave distant rooms weak even when the router is newer.
Test a better position first. If several rooms remain weak, compare a multi-node mesh layout with a single-router replacement rather than relying on a maximum-speed figure.
Published equipment figures describe particular capabilities or test conditions, not the connection each device will achieve through your walls and broadband service.
Check which devices and broadband connection you actually use, where nodes can go, and whether wired connections between them are practical.
These ranges illustrate different equipment routes; a brand range does not establish how a particular model will perform in your home.
TP-Link offers Archer routers, RE extenders and Deco mesh systems, so the equipment choice can follow the location and extent of the weak signal.
eero lists the eero 7, eero Pro 7 and eero Max 7 in its mesh range.
NETGEAR positions Orbi mesh systems for whole-home coverage; specifications vary by series and pack.
These options cover multi-room mesh systems and an extender for one reachable weak area. Check your broadband service and router position before deciding whether either route addresses the problem.

A three-unit mesh option to consider when weak coverage persists in several rooms. TP-Link specifies tri-band Wi-Fi 7, four 2.5 Gbps ports per Deco BE65 unit and wired or wireless backhaul; placement, walls and the broadband service still affect results.
No image available
A three-unit mesh option for coverage across several rooms. The product name specifies dual-band BE3600 and 2.5Gbps Ethernet; check how the system connects to your existing broadband equipment and where its units can be positioned.

This three-unit mesh system is an option for weak coverage in several rooms. If wired connections matter to your setup, confirm the exact Ethernet port configuration before buying; room layout and node placement also matter.
No image available
A three-pack mesh option when you need coverage from more than one position in the home. Confirm the included units and compatibility with your broadband setup, then plan their positions around the rooms and walls causing trouble.

Consider this extender for one weak area if it can receive a usable signal between that area and the router. TP-Link specifies dual-band Wi-Fi 7, a Gigabit Ethernet port and EasyMesh compatibility; coordinated roaming requires compatible equipment.
Investigate the broadband connection first if performance is poor close to the main router as well as in distant rooms. Check for an outage and simultaneous heavy use, then look at service options for your postcode. Ofcom notes that Wi-Fi cannot outperform the broadband service feeding it; a mesh system addresses in-home coverage, not that incoming limit.
Place it between the router and the weak area, where it still receives a usable Wi-Fi signal—not deep inside the dead zone. Adjust the position if walls or other obstacles weaken its connection to the router.
No particular mesh pack guarantees coverage in every room. The number and position of nodes, wall materials and the connection between nodes all matter; check the layout before deciding how many units you need.
Possibly, but confirm the connection type, provider requirements and any provider-specific services before buying a retail router. Ofcom cautions that third-party routers can be more difficult to set up and may receive less support from the broadband provider if problems arise.
