First move your existing router to a central, elevated, open spot. If a room still has weak Wi‑Fi, a second access point connected by Ethernet—or, where suitable coax is already installed, MoCA—can extend coverage without relying on a wireless relay. Mesh remains useful in larger or difficult-to-cover homes where running a cable is impractical.
Why mesh is not always the answer
A mesh system uses multiple units to extend coverage around a home. It solves a real problem when one router cannot reliably reach several areas, but it does not automatically make an internet plan faster or improve every device’s connection. With wireless backhaul, traffic from a satellite node has to travel wirelessly to the main router, using some of the available radio capacity. A wired link avoids that relay path.

Whether mesh is worthwhile depends on the home’s layout, construction, interference, device load, and router placement. WIRED’s 2026 guide gives a modern timber-frame and drywall home of 2,500 square feet or less as a rough example where one router may suffice; it says mesh is likely useful at 3,000 square feet or more, particularly with thick walls or interference. Those are rules of thumb, not universal size thresholds. The same guide reports its author’s experience testing more than 60 routers and mesh systems: single routers generally performed better in a 1,600-square-foot, two-story house, while mesh proved useful in a later Victorian house with thick stone walls. These are reported experiences, not a guarantee for another home. WIRED’s router-versus-mesh guide
Check what is actually slow before spending
Broadband service speed, Wi‑Fi coverage, and the speed reaching an individual device are related but different. A weak result in one room may be a Wi‑Fi problem; a slow result everywhere may instead involve the incoming broadband service, equipment, or a particular device. Check the service near the main router before concluding that you need more access points.

- If performance is good near the router but poor in particular rooms, placement or in-home coverage is a likelier issue.
- If only one device is slow, compare with another device in the same spot before changing the network.
Ofcom’s guidance also identifies connection speed, coverage, device count, optimisation, and security as relevant when choosing Wi‑Fi equipment. Its listed speed categories—Wi‑Fi 6 “600 Mbps+,” Wi‑Fi 5 “200 Mbps,” Wi‑Fi 4 “100 Mbps,” and Wi‑Fi 3 “20 Mbps”—are simplified typical maximum categories on that guidance page, not expected household speeds.

Try the no-cost fix: move the router
Before buying anything, put the existing router as near the centre of the area that needs coverage as the modem or fibre termination allows. Raise it, leave space around it, and avoid hiding it in a cupboard or placing it behind furniture. Brick, metal, water, and other obstructions can weaken Wi‑Fi; microwaves and cordless phones can also interfere. Ofcom recommends central, elevated, unobstructed placement and avoiding sources of interference. Ofcom’s placement advice

Cheaper alternatives to a mesh kit
| Option | Best fit | Main constraint |
|---|---|---|
| Reposition the existing router | Coverage is uneven and the current placement is poor | The modem or fibre connection may limit where the router can go |
| One suitable router | A modest, relatively open home without multiple persistent dead zones | Reach can be limited by layout, walls, and interference |
| Ethernet to an access point | A cable can be routed, or Ethernet is already installed | Running cable through a finished home takes effort |
| MoCA adapters and an access point | Usable coax outlets connect the rooms that need a wired link | Coax topology, connected services, and adapter compatibility matter |
| Powerline adapters | There is no practical Ethernet or coax route and the electrical wiring performs well | Throughput and stability vary with wiring and interference |
| Wireless mesh | Several areas need coverage and cable-based backhaul is impractical | Costs more than a placement fix; nodes need usable signal and power |
Ethernet: the most direct wired backhaul
If you can route a cable, connect the primary router’s LAN to an access point or a compatible second router configured for the intended network setup. A Cat6 cable can carry the link; the difficult part may be getting it neatly through a finished home. Follow the equipment maker’s instructions for access-point or second-router mode rather than assuming every device uses the same setup.

MoCA: use coax already in the walls
MoCA adapters can carry a network connection over suitable coax, allowing an access point in another room to receive a wired link without running a new Ethernet cable. Before buying, confirm that the outlets at both ends connect through the same suitable home coax network. Check splitters and other connected equipment, as well as compatibility with TV or broadband services. Motorola and Verizon warn that satellite-TV-associated coax or satellite-based home networks are not suitable for the setups they document. Verizon also notes that MoCA bandwidth is shared among connected devices and that older protocol support can affect performance.
MoCA 2.5 is described by the Multimedia over Coax Alliance as having capability up to 2.5 Gbps. That is a protocol capability, not a promise of end-to-end Wi‑Fi speed: the broadband service, adapters, access point, coax network, and client device all affect the result.

Powerline: test before relying on it
Powerline adapters send network traffic over electrical wiring. Their advertised rates are not a room-speed promise: wiring layout, condition, and electrical interference affect real results. WIRED’s 2026 guide says powerline is unlikely to exceed 300 Mbps in real use and that 50–100 Mbps is often more realistic, based on its author’s experience. That is a publication’s reported experience, not a general benchmark. Test the actual sockets and intended room before relying on powerline for gaming, calls, or other latency-sensitive work.

When a mesh system makes sense
Mesh is a reasonable choice when a home has multiple coverage gaps, difficult walls or floors, or a layout where running Ethernet or using coax is not practical. It can also be simpler than placing and configuring separate access points. Check whether the system supports wired backhaul if you can connect its nodes by Ethernet or MoCA; otherwise, place each wireless node where it still receives a usable signal from the main router, generally between that router and the weak-coverage area rather than deep inside the dead zone.

Do not choose by node count or advertised coverage alone. Consider where each node can be powered and placed, whether it supports a wired link, compatibility with your devices, and whether your weak areas are actually reachable from a suitable node location. A mesh kit cannot fix a weak broadband service coming into the home.
Secure the network whichever setup you choose
Adding an access point or second router is not a reason to leave default settings in place. The FTC recommends WPA3 Personal or WPA2 Personal encryption, changing the default administrator credentials and network name, and keeping router software updated. It also recommends turning off remote management, WPS, and UPnP when you do not need them. FTC: How To Secure Your Home Wi‑Fi Network
