People working or studying across several rooms
Wi-Fi weakens away from the main router in rooms you use regularly. Your priority is coverage where you work or study, rather than a faster connection beside the hub.
Who this is for
Households sharing a busy connection
Calls, streaming, downloads or gaming happen at the same time. You need to establish whether the problem is weak Wi-Fi in particular rooms, competing demand or the broadband service itself.
People using fixed gaming or media devices
A desktop, console or television stays in one place. If a cable route is practical, compare Ethernet with buying more wireless equipment for that device.
What matters when choosing
Check whether the problem follows you into several rooms or affects the connection even beside the hub. That distinction helps you decide whether to consider mesh, a single extender, a router change, Ethernet or provider support.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Identify every regularly used weak-signal room. Check where a mesh main unit can connect by Ethernet and where other units could go; for one limited weak area, consider whether an extender can receive a usable signal. | I need Wi-Fi for work or study in more than one room away from the hub. Roughly 33% of consumers put multi-room coverage first. |
| Broadband or household demand | Compare performance near the hub or over Ethernet where practical, check for an outage and note simultaneous data-heavy use before choosing new equipment. | When several people are online, I need to know whether weak Wi-Fi or the shared connection is slowing us down. Around 27% of consumers prioritise identifying the service or demand problem. |
| Fixed-device reliability | Check whether the affected desktop, console or TV has an Ethernet port and whether a cable can reach an appropriate network port. | My gaming or streaming device stays in one place, so a practical wired connection matters more to me than wider wireless coverage. Approximately 20% of consumers make fixed-device reliability their primary concern. |
| Hub compatibility and setup | Confirm the hub connection, the exact model’s operating modes and which features remain available when the existing router stays in charge. | I want to keep my provider hub and the network features I use without buying an incompatible addition. For roughly 20% of consumers, setup and compatibility come first. |
Buying pitfalls
-
Buying mesh before checking the broadband connection
Better Wi-Fi coverage cannot repair a provider outage or increase the speed of an inadequate broadband service. Ofcom advises checking equipment, service problems and competing household use when diagnosing slow connections.
Test near the hub or over Ethernet where practical, and check the provider’s service status before deciding that weak room-to-room coverage is the cause.

Expecting a Deco unit to repeat the hub’s signal wirelessly
TP-Link says the main Deco needs a physical Ethernet connection to the modem or existing router; it cannot act as a wireless repeater of that router.
Plan the main unit’s wired position and check whether Router or Access Point mode suits the network you want to keep.
-
Assuming any new disc or router will extend an existing mesh
BT says its Whole Home Wi-Fi product families cannot be mixed with one another. ASUS AiMesh also requires supported routers, even though compatible models can differ.
Check the exact existing and proposed model numbers against the manufacturer’s expansion guidance before ordering.
An incompatible unit may mean replacing equipment rather than extending the current network.
-
Choosing Access Point mode without checking features
In TP-Link Deco Access Point mode, the existing router remains the gateway, and some Deco gateway functions are unavailable.
Check which device will provide any routing, parental controls or other network features you rely on for the exact model and operating mode.
Relevant brands to consider
These product families illustrate different ways to build a home network; compatibility and features depend on the exact models.
TP-Link Deco
A mesh family that can be used alongside an existing router in Router or Access Point mode.
- TP-Link says the main Deco connects to a modem or router by Ethernet, so plan a wired position for it.
- Deco does not repeat an existing router’s Wi-Fi wirelessly. In Access Point mode, check which gateway features remain available.
BT Whole Home Wi-Fi
A mesh family intended to work with broadband hubs or routers that have an RJ45 Ethernet port, according to BT.
- It offers a route to adding Wi-Fi coverage while retaining a compatible broadband hub.
- BT says its Whole Home Wi-Fi, Mini, Premium and Wi-Fi 6 families are not mutually compatible; check the family before adding discs.
ASUS AiMesh
A way to form a mesh network from supported ASUS routers, including compatible routers of different models.
- ASUS describes a setup with a designated main router and at least one supported router as a node.
- Check each router’s AiMesh support, model compatibility and firmware before planning an expansion.
NETGEAR Orbi
A dedicated mesh family with app or browser management options described by NETGEAR.
- NETGEAR describes Orbi as usable with internet service providers while offering network management through its app.
- Check the exact model’s hub connection, ports and any conditions attached to the features you intend to use.
Mesh systems on Joybuy
These three-unit mesh systems are choices to consider when weak Wi-Fi affects several rooms and the broadband service itself is working adequately. Check how each main unit will connect to your existing equipment before choosing a kit.

NETGEAR Orbi 370 RBE373 BE3600, 3-pack
Consider this three-unit mesh kit where several regularly used rooms have weak Wi-Fi. The product name specifies dual-band Wi-Fi 7 and 2.5Gbps Ethernet; check the exact hub connection and port arrangement for your planned setup.
No image available
TP-Link Deco BE22 BE3600, 3-pack
Consider this three-unit Deco system for weak Wi-Fi across several rooms. Its product name specifies Wi-Fi 7 and BE3600; TP-Link says a Deco main unit must connect by Ethernet, so confirm the intended position and operating mode.
No image available
TP-Link Deco BE25 Wi-Fi 7, 3-pack
Consider this three-unit mesh system when coverage is weak in more than one room. The product name specifies Wi-Fi 7; check the Ethernet port arrangement if you also intend to connect fixed devices, and plan a wired connection for the Deco main unit.
No image available
TP-Link Deco BE65 BE9300, 3-pack
Consider this three-unit kit for weak coverage in several rooms. Its product name specifies tri-band Wi-Fi 7 and BE9300; confirm its Ethernet ports, main-unit placement and operating mode against your existing hub before buying.
Common questions
Should I contact my broadband provider before buying mesh Wi-Fi?
Contact your provider first if the connection stops working or is unreliable throughout the home, rather than only in distant rooms. Ofcom advises checking service status and household usage when diagnosing problems; a mesh kit will not fix a provider fault.
Can mesh Wi-Fi work with my existing broadband hub?
It can, provided the exact system and hub support the intended connection and setup. For example, TP-Link says Deco can work alongside an existing router in Router or Access Point mode, but its main unit needs a physical Ethernet connection.
Is an extender enough for one weak room?
An extender is worth considering for one limited weak area if it can receive a usable Wi-Fi signal to repeat. Ofcom says extenders can improve reach but may affect speed and responsiveness, so widespread weak coverage calls for a different assessment.
When is Ethernet a better option than another Wi-Fi unit?
Use Ethernet for a fixed desktop, console or television when a practical cable route and suitable ports are available. Ofcom recommends a direct Ethernet connection for a computer where connection speed and reliability matter; it will not extend Wi-Fi to mobile devices.
Would replacing my router help instead of adding mesh?
Consider a router change if the current router itself is the problem, after checking that the broadband service is working adequately. Ofcom notes that retail routers can be trickier to set up and that a provider may be unable to help with problems involving one, so check the setup and support implications before replacing the hub.
