Check the incoming broadband connection before buying Wi-Fi equipment: Ofcom notes that Wi-Fi cannot outperform the service delivered to the home. If the service is sound, Ethernet is worth assessing for a fixed call desk, while mesh or a wired access point can address weak coverage in other rooms. A replacement router needs to suit the existing connection; powerline is an option to test where running Ethernet is impractical, because its performance depends on the property’s wiring.
If the call computer stays in one place, assess whether an Ethernet cable can reach it safely. Ofcom advises that a direct Ethernet connection to the router should provide a faster, more reliable local link than Wi-Fi. Check the computer’s port or adapter needs as well as the cable route.
When calls work near the router but falter upstairs or behind walls, consider mesh Wi-Fi or a wired access point for the affected rooms. The useful choice depends on where units can be placed and whether Ethernet can reach them; neither route makes the incoming broadband service faster.
Meetings, streaming and downloads can happen at once on a shared connection, as Ofcom’s household guidance describes. Compare performance near the router with performance in the call room, including when others are online, before deciding whether the problem calls for local network equipment or attention to the broadband service.
Start by locating the problem, then choose equipment for the particular desk or rooms affected. The checks differ for a wired computer, wider Wi-Fi coverage and a change to the existing router setup.
| Priority | What to check | Your needs |
|---|---|---|
| Find the bottleneck | Compare results near the router or over Ethernet with those in the problem room. Repeat tests at different times, as Ofcom advises, and check for a provider fault if performance is poor throughout the home. | My calls fail even close to the router, or the whole household slows down when several people are online. I want to understand whether new Wi-Fi equipment would address the problem. |
| Connect a fixed desk | Check for a safe Ethernet route to the router or a wired network point. Confirm the computer has an Ethernet port or a compatible adapter; a wired desk connection will not extend Wi-Fi to other rooms. | I take calls from the same desk and can use a cable there, even if other household devices remain on Wi-Fi. |
| Cover distant rooms | Identify where the signal weakens and where mesh units or an access point could go. Check the connection between mesh units: TP-Link’s guidance describes Ethernet backhaul as a way to avoid a wireless hop where cabling is available. | Calls become unreliable upstairs or in several rooms away from the router. I need coverage where people actually work and move around, not just beside the main unit. |
| Share the connection | Check whether trouble occurs only during simultaneous calls, streaming or downloads. Compare near-router and room-to-room performance while the household is using its usual devices; Wi-Fi equipment cannot increase the incoming service speed, as Ofcom explains. | A meeting needs to remain usable while someone else is streaming or working. I need to know whether the weak point is the call device’s Wi-Fi link or the connection everyone shares. |
| Keep or replace the router | Confirm how the existing broadband equipment connects and which router or access-point modes the chosen system supports. Check its wiring instructions before assuming an added mesh unit can work wirelessly with the existing router. | I want better local Wi-Fi but may need to keep my provider’s equipment. Setup compatibility matters more to me than replacing hardware unnecessarily. |
| Try powerline | Check that the intended adapters and sockets suit the planned connection, then test the link in the actual rooms. Devolo says powerline data rates vary with electrical noise, distance, traffic and the installation. | Running Ethernet is impractical, and walls or floors make a direct wireless link difficult. I can assess whether the home’s wiring gives my work room a usable connection. |
Mesh can extend local Wi-Fi coverage, but Ofcom notes that it cannot make the incoming service faster. Poor results even over Ethernet, or a problem affecting the whole household, point to a different issue.
Test near the router or over Ethernet at several times and check the provider’s fault information before choosing coverage equipment.
Walls, floors, placement and the link between units affect whether a call location receives a usable connection. A pack’s coverage figure does not establish performance in a particular home.
Identify the troublesome rooms and plan unit positions around them. Consider Ethernet backhaul where a cable can reach the units.
A difficult layout may call for another unit or a cable route.
The replacement must work with the existing broadband connection. If a second router is added, its operating mode also matters: TP-Link warns that some combined modem-router arrangements can create double network address translation (NAT).
Check the connection method, any equipment that must stay in place and the chosen system’s router or access-point instructions before ordering.
A change of router can also mean more setup and troubleshooting time.
Devolo says actual data rates depend partly on the electrical installation, distance, traffic and noise. A headline rate cannot tell you how the connection will behave in the upstairs work room.
Test the adapters in the intended sockets before relying on that route for calls, and check the seller’s return terms before purchase.
These ranges illustrate different setup routes; a brand’s inclusion here does not establish that a particular model suits your gateway or floor plan.
The Deco range includes home mesh systems for extending Wi-Fi across rooms.
The Orbi range includes multi-unit mesh systems aimed at connected homes.
The Magic powerline range uses a home’s electrical wiring to carry a network connection to another room.
These options cover multi-room mesh systems and an adapter for connecting a computer at a fixed desk. Choose between those uses only after checking whether the problem lies with local Wi-Fi or the incoming broadband connection.

This three-unit mesh system is relevant when Wi-Fi needs to reach multiple call locations. Check unit placement and compatibility with the existing gateway; if the plan relies on wired backhaul, confirm the necessary ports and support for this variant before buying.
No image available
A three-unit, dual-band mesh option for rooms with weak Wi-Fi; the product name also specifies 2.5Gbps Ethernet. Confirm how it would connect to the existing modem or gateway and where its units could be placed. The stated Ethernet specification does not establish call performance in a particular home.
No image available
An adapter to assess for a fixed call computer that needs an RJ45 LAN connection; its product name also lists three USB 3.0 ports. Confirm that the computer has a compatible USB connection, and check the cable needed to reach the router or network point. It will not extend Wi-Fi coverage for other devices.

A three-unit mesh option for assessing coverage across several rooms. Check its supported operating mode with the existing gateway and, if wired connections matter, the Ethernet port roles and backhaul arrangement for this variant. A three-pack alone does not establish coverage in every room.
Compare the call room with a connection near the router or over Ethernet, and repeat tests at different times. Ofcom notes that Wi-Fi cannot outperform the incoming broadband service: if performance is poor throughout the home, check the provider’s fault information rather than assuming mesh will fix it.
Ethernet is worth assessing when you can run a cable safely to the desk. Ofcom says a computer connected directly to the router by Ethernet should have a faster, more reliable local connection than over Wi-Fi. Check the computer’s port or adapter needs; the cable will not improve Wi-Fi coverage elsewhere.
Consider mesh when several rooms need wider Wi-Fi coverage; an extender targets a more specific area. That is how UK consumer publisher Which? distinguishes the two approaches. For calls across rooms, check mesh-unit placement and the link between units rather than treating an advertised coverage figure as a guarantee.
You may be able to, if the chosen system supports the required setup. TP-Link documents an access-point arrangement for Deco with an existing router, but says the main Deco unit needs a physical Ethernet connection. Check the exact model’s instructions and the existing gateway before buying.
Powerline is an option to test, not a guaranteed fix. It carries data over electrical wiring, and devolo says its actual rate varies with factors including distance, electrical noise and the installation. Try the intended sockets before relying on the link for work calls.
