Before buying network equipment, compare a wired test at the router with Wi-Fi in the rooms where calls fail, including at busy times. If the incoming connection is the problem, check broadband options for your address; if only distant rooms struggle, consider mesh Wi-Fi or a wired connection, while router replacement is more relevant when the router itself is unsuitable. Check how any new equipment will connect to your provider’s hub.
If calls fail mainly in a bedroom, loft or other room away from the router, compare performance there with a test near the router before paying for more coverage. Ofcom’s Wi-Fi guidance explains why the wireless connection within the home can be a separate issue from the broadband service.
When several people are online, check whether the incoming broadband service or the in-home Wi-Fi is limiting calls before choosing what to change. Ofcom advises checking the services available at the household’s address.
If the main problem is at one stationary device, compare a direct Ethernet connection before replacing Wi-Fi throughout the home. Which? recommends testing a computer connected directly to the router when assessing the service delivered by a provider.
Consider: When a wired test at the router also performs poorly, check the services and predicted speeds for your address with Ofcom’s checker and discuss any fault with your provider.
Trade-off: A faster package will not by itself resolve weak Wi-Fi in a distant room, and predicted speeds are not a guarantee of the speed a property will receive.
Consider: A replacement or access-point-capable router may suit a home where the existing router is unsuitable but the important rooms can be covered from a suitable position.
Trade-off: Check whether the provider’s hub must stay in place and how the new device will connect; provider arrangements differ.
Consider: Mesh nodes may suit a home where Wi-Fi remains weak across several rooms or floors despite an adequate incoming service.
Trade-off: Nodes need suitable positions and a connection to the existing gateway; mesh cannot improve the broadband service itself.
Consider: Ethernet can suit a fixed work or study device when a cable route is practical; powerline is an alternative to assess when running cable is impractical.
Trade-off: Ethernet needs a workable route, while powerline results depend on the home’s electrical wiring.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Coverage in calling rooms | Map weak rooms and possible node positions; check whether the system supports the intended wired or wireless backhaul. | If calls fail in rooms far from the router, I want coverage where people actually work or study. About 33% of consumers put calling-room coverage first. |
| Incoming service during busy periods | Compare wired and room-level tests when calls usually fail; check predicted speeds and service availability for the address. | When several people are online, I want to know whether the connection coming into the home is the limit before changing Wi-Fi equipment. About 25% of consumers prioritise incoming broadband capacity. |
| Router and provider setup | Identify the existing hub and connection type; confirm provider settings and whether new equipment will act as a router or access point. | If the current router seems unsuitable, I want to know whether new equipment can work with the provider’s setup before replacing anything. About 17% of consumers prioritise a router change. |
| One fixed device | Check whether Ethernet can reach the desk, whether an adapter is needed and whether a powerline kit includes what is required to start a network. | For one stationary call or study device, I would rather check a direct connection than change Wi-Fi across the whole home. About 25% of consumers prioritise a wired link for one device. |
Mesh equipment cannot make the broadband service feeding it faster. A weak Wi-Fi result alone does not establish that the service is at fault.
Compare a wired test at the router with Wi-Fi in the affected room, then check address-specific service options or ask the provider about a fault if the wired connection also performs poorly. Ofcom notes that Wi-Fi test results do not always indicate a broadband-line fault.
Walls, floors and the positions of the router and nodes affect the connection in individual rooms; a coverage figure cannot guarantee a particular home’s result.
Map where calls fail and consider possible node positions before choosing a system. If Ethernet is available between locations, check whether the system supports wired backhaul.
An extra node or a cable run may be needed if the initial placement does not reach the rooms used for calls.
Provider arrangements differ, and third-party equipment may need to sit behind the existing hub rather than replace it.
Identify the hub, ONT or modem and ask the provider how a third-party router or mesh system should connect. Follow instructions for your own provider and setup rather than applying another provider’s settings.
A new powerline network needs an adapter connected to the router and another at the destination in devolo’s documented setup. The company also says its Magic adapters are not compatible with its dLAN range.
Check the kit contents and the adapter family you already own. Powerline results depend on the home’s wiring.
A second compatible adapter may be needed to establish a new network.
These brands relate to different home-networking options; specifications and compatibility notes apply to the named products or ranges, not to every product from a brand.
The UK Deco X50 V2 product information describes a Wi-Fi 6 mesh system with optional Ethernet backhaul.
The RT-AX58U is a standalone Wi-Fi 6 router that can also be considered for access-point operation.
The Halo H80X three-pack is a mesh option for readers comparing multi-room systems.
eero is relevant when deciding whether to keep a provider hub or connect a mesh system to an ONT.
devolo Magic powerline products are relevant when a distant desk needs a connection and running Ethernet cable is impractical.
These Joybuy options cover mesh Wi-Fi for multi-room coverage and a powerline kit for a more local connection. Check that the selected equipment suits your provider setup and home before buying.

Compare a computer connected to the router by Ethernet with Wi-Fi in the room where calls fail, including at times when problems usually occur. A poor Wi-Fi result alone does not establish a line fault; if the wired connection also performs poorly, contact your provider. Ofcom advises that a slow Wi-Fi test does not always mean the broadband line is faulty.
Check the incoming service before choosing: if a wired test at the router is poor, investigate the connection and address-specific broadband options; if only distant rooms struggle, compare coverage options such as mesh or Ethernet. Ofcom notes that Wi-Fi cannot outperform the broadband service feeding it, and a service upgrade does not by itself fix weak room-level coverage.
Often mesh can connect to an existing router, but the right setup depends on the provider and equipment. eero’s UK instructions give different examples for BT FTTP and Vodafone, so confirm the instructions for your own hub and mesh system before buying.
Check whether you already have a compatible powerline network and whether the adapter belongs to the same product family. In devolo’s documented setup, a new network needs an adapter by the router and another at the destination; Magic and dLAN adapters are not interchangeable. Results also depend on the home’s wiring.
Use Ofcom’s broadband checker to review service types and predicted speeds for the specific address, then confirm details with the provider. Predicted speeds are not a guarantee of what an individual property will receive.
