Who needs a Wi-Fi upgrade?

Households with weak signal in several rooms

If distant rooms or floors repeatedly lose Wi-Fi, the decision is about coverage across the home, not just the connection to one device. Which? discusses extenders and mesh systems as different ways to reach weak areas.

Households using many devices at once

When people stream, game, study and work simultaneously, it matters whether the slowdown occurs on the home Wi-Fi or on the broadband service itself. Ofcom advises distinguishing Wi-Fi performance from broadband speed before deciding what to change.

Households with one isolated weak room

One weak room may call for a targeted connection rather than a whole-home change. An extender needs a usable router signal at its proposed location; powerline depends on suitable sockets and wiring, according to TP-Link’s setup guidance.

What should you check before choosing?

Start with a wired or near-router comparison and your provider’s service status. If the broadband connection is working as expected, use the pattern of weak rooms and the number of active devices to choose a route.

Replacement router

Consider it when: Wi-Fi performance is poor near the current router or falls off as more devices connect.

Trade-off: A new router cannot increase the speed delivered by the broadband service, and your provider’s connection and support arrangements may affect setup.

Mesh Wi-Fi

Consider it when: Several rooms or floors have recurring weak signal and you need coverage across those areas.

Trade-off: Multiple units need suitable positions and a reliable connection between them; the home’s layout affects the result.

Wi-Fi extender

Consider it when: One room is weak but an intermediate socket still receives a usable router signal.

Trade-off: Placement is restrictive, and Ofcom notes that extenders can affect speed and responsiveness compared with mesh systems.

Powerline adaptor

Consider it when: A weak room could be served through suitable wall sockets on the same electrical circuit.

Trade-off: The electrical arrangement must suit the kit; TP-Link advises direct wall outlets rather than power strips.

Concern What to check Who this matters to
Coverage across rooms Identify the rooms or floors that repeatedly lose signal and where mesh units could maintain a connection. If several distant rooms drop out, I need coverage beyond a single weak spot. Around 33% of consumers put whole-home coverage first.
Several devices online Compare a wired or near-router test with results elsewhere, especially while household devices are active. Streaming, gaming, study and work compete for a dependable connection in my household. For around 27% of consumers, performance with several devices is the primary concern.
One weak room Check whether an intermediate extender socket receives usable Wi-Fi from the router. I want to reach one weak room without changing coverage throughout the home. Fixing that isolated spot comes first for around 20% of consumers.
Diagnosis and compatibility Check service status and your provider-hub setup; for powerline, confirm that the intended wall sockets are on the same circuit. Before buying, I need to know that new equipment can address the problem and work with my setup. Around 20% of consumers make that their primary concern.

Purchasing pitfalls

  • Assuming slow Wi-Fi means the router needs replacing

    Ofcom explains that a Wi-Fi speed test can be affected by the connection inside the home and that Wi-Fi cannot outperform the broadband service. New network equipment will not resolve a provider outage.

    Compare an Ethernet or near-router test with results in weak rooms, and check your provider’s service status before choosing hardware.

  • Putting an extender in the dead zone

    An extender needs to receive the router’s signal before it can serve the weak room. TP-Link advises placing it roughly halfway between the router and the affected area, within usable router range.

    Check the proposed socket and its signal before deciding that an extender fits the room.

  • Assuming powerline works through any socket

    TP-Link’s basic setup guidance calls for at least two units on the same electrical circuit and recommends wall outlets rather than power strips.

    Check the intended sockets and circuit before choosing a kit; consider the seller’s return process if performance in your wiring remains uncertain.

  • Replacing a provider hub without checking the setup

    Provider requirements differ. BT Business says its hub may need to be reconnected for fault diagnosis; Virgin Media says modem mode disables certain Hub features and is unavailable on Hub 5x.

    Identify your provider, connection type and hub model, then confirm how a separate router would connect and be supported.

    Allow time for setup and keep the provider hub available if it may be needed during fault diagnosis.

Brands to consider

TP-Link

TP-Link offers range extenders, Deco mesh systems and powerline products relevant to different coverage problems.

  • TP-Link’s own guidance suggests an extender for a single weak spot and Deco mesh for coverage across multiple rooms or floors.
  • Extender placement and powerline wiring still need checking in the home; the brand’s route guidance does not establish comparative performance there.

ASUS

ASUS is relevant if you are considering a standalone router and might later add compatible routers to an AiMesh network.

  • ASUS says AiMesh can combine compatible ASUS router models into one network.
  • Check compatibility for the exact models you intend to combine; a mesh feature name alone cannot establish coverage in your home.

NETGEAR

NETGEAR’s Nighthawk routers and Orbi mesh systems represent router and multi-unit coverage routes.

  • NETGEAR describes extenders as a way to reach rooms outside router range and mesh as a network using multiple devices.
  • Actual reach depends on the chosen product, its placement and the home’s layout.

Frequently asked questions

How do I tell whether the problem is broadband or home Wi-Fi?

Compare an Ethernet or near-router test with results in the affected rooms and check your provider’s service status. Ofcom notes that a slow Wi-Fi test does not necessarily indicate a broadband-line fault: distance, walls, devices and other use of the connection can affect it. Compare your results with the speed expected under your broadband agreement before buying Wi-Fi equipment.

Can I use my own router with my broadband provider?

It depends on the provider, connection and hub model, so confirm the setup before replacing the router. BT Business says its hub may need to be reconnected for fault diagnosis. Virgin Media says modem mode is unavailable on Hub 5x and disables certain Hub features while active on supported models.

Should I choose an extender or mesh for a weak room?

For one weak room, consider an extender if a socket between that room and the router still receives a usable signal; TP-Link advises positioning it roughly halfway. If several rooms or floors are repeatedly weak, a multi-unit mesh system addresses the broader coverage task, though unit placement remains important.

Will powerline adaptors work with any sockets?

Do not assume they will. TP-Link says a basic powerline connection needs at least two units on the same electrical circuit and recommends plugging them directly into wall outlets rather than power strips. Check the intended locations before choosing this route.
