Households with gaps across the home
Wi-Fi works near the main router but is weak in several rooms, on another floor or beyond difficult internal walls. Ofcom advises checking router position as well as the connection itself.
Who this is for
Households with several simultaneous users
Video calls, learning, streaming or downloads overlap. The useful distinction is whether the broadband service slows for everyone or the problem lies with the wireless connection inside the home, as Ofcom explains in its Wi-Fi guidance.
Households with one weak area
Most rooms work acceptably, but a bedroom or study has unreliable Wi-Fi. A targeted extension may be worth considering once there is a suitable position between the router and that area.
What to check before buying
Start with router placement and a connection test. That separates problems a Wi-Fi device might address from a broadband-service limit that calls for provider support or a service change.
Replacement router
Consider it when: The main hub appears to be the in-home bottleneck and the broadband connection itself performs adequately.
Allow for: Provider-specific setup and support conditions; a new router cannot raise the broadband service's speed ceiling.
Mesh system
Consider it when: Weak Wi-Fi persists across several rooms or floors after improving the main router's position.
Allow for: Space for suitably positioned nodes and a sound connection between them; mesh does not fix an inadequate broadband service.
Extender or booster
Consider it when: One area is weak while the rest of the home works acceptably.
Allow for: A position where the device can still receive a usable signal from the main router; network-integration features depend on compatibility.
Broadband service or provider support
Consider it when: Performance is poor even close to the router or over a wired connection.
Allow for: A service change will not remove Wi-Fi dead zones caused by router position or the home's layout.
| Concern | What to check | Who this matters to |
|---|---|---|
| Coverage across rooms | Try a more central, elevated router position; map remaining weak rooms before choosing mesh nodes. | If I lose Wi-Fi in several rooms, reaching those spaces matters more than improving the signal beside the router. Around 36% of consumers put whole-home coverage first. |
| Simultaneous use | Test the connection at different times, including when several people are online; consider Ethernet for a stationary priority device. | When calls and streaming overlap, I need to know whether everyone is limited by the service or by in-home Wi-Fi. Stable simultaneous use comes first for around 29% of consumers. |
| One weak area | Check for a position between the router and weak room where an extender receives a usable signal; verify any compatibility feature. | If only my study struggles, I want to address that room without changing a network that works elsewhere. Around 21% of consumers prioritise a contained dead zone. |
| Broadband-service limit | Compare tests near the router or over Ethernet with your service details, then ask the provider to investigate persistent problems. | When even a wired device is slow, I need to resolve the connection reaching the home before adding Wi-Fi equipment. That service limit is the primary concern for around 14% of consumers. |
Buying pitfalls
-
Buying Wi-Fi kit before testing the connection
Ofcom notes that Wi-Fi cannot outperform the broadband service. A new router or mesh system will not remove a limit on the connection reaching the home.
Test at different times and, where practical, compare a device near the router with one connected by Ethernet before choosing equipment.
-
Expecting mesh to cure every slowdown
Mesh addresses wireless coverage inside the home, not an inadequate broadband connection. Node distance and building materials also affect coverage, as ASUS notes in its ZenWiFi guidance.
Use it for persistent gaps across rooms or floors, and plan where the nodes can go before choosing a pack size.
-
Assuming any retail router can replace the supplied hub
Provider and plan conditions differ. Vodafone requires its router for Pro Broadband and Digital Voice plans, while BT Business says its main helpdesk does not support third-party routers.
Check your exact plan, voice service, connection type and setup requirements before ordering a replacement.
You may need to keep the supplied hub available and reconnect it when seeking fault support.
-
Overlooking software support
A device may remain in use long after its initial setup, so its security-update information matters. The National Cyber Security Centre advises consumers to look for the stated minimum period for important updates.
Check the exact product's update-support information, set a strong unique password and install available updates.
Brands to consider for home Wi-Fi
TP-Link
The Deco range covers multi-node home Wi-Fi systems, making it relevant when several rooms need coverage rather than one new router.
- TP-Link offers Deco packages with different node counts and Wi-Fi standards.
- Check the exact pack, ports and compatibility; TP-Link's range-wide coverage and capacity claims do not establish results in a particular home.
NETGEAR
Orbi is NETGEAR's multi-node range for household coverage.
- The range gives consumers a mesh option to assess for gaps across several rooms.
- NETGEAR's whole-home claims are brand positioning; compare the exact model's node count, ports and connection requirements.
ASUS
ZenWiFi is an expandable mesh family managed through the ASUS Router app.
- Expansion is relevant if you want to plan a network around more than one access point.
- ASUS notes that node spacing and building materials affect coverage, so a stated coverage figure cannot be assumed for your layout.
eero
eero offers app-managed mesh systems, including Wi-Fi 6 and Wi-Fi 7 products.
- An app-managed package may suit consumers who want to assess setup and network management together.
- Check the exact package, Ethernet connections and terms for optional features rather than applying one eero model's claims to the whole range.

Common questions
How can I tell whether Wi-Fi or broadband is causing the slowdown?
Compare performance at different times, close to the router and, where practical, over Ethernet. Ofcom says Wi-Fi cannot outperform the broadband service; if a wired device also performs poorly, ask your provider to investigate before buying Wi-Fi equipment.
Will a mesh system make my broadband faster?
No: mesh distributes Wi-Fi around the home but does not increase the speed of the broadband service reaching it. Ofcom describes mesh as a way to improve in-home signal and coverage, so it is worth assessing when the connection is adequate but rooms remain weak.
Can I replace my broadband provider's router?
Check the provider and plan before buying a replacement. Vodafone requires its own router for Pro Broadband and Digital Voice plans; BT Business permits compatible third-party routers but says its main technical helpdesk does not support them. Confirm your connection settings and any voice-service requirements too.
What does a replacement router need for an Openreach full-fibre connection?
Openreach guidance describes a powered-on optical network terminal connected by CAT5e or Cat6 cable to the router's WAN port. Check that the router has the needed Ethernet WAN connection and confirm your broadband provider's authentication and voice-service arrangements before changing equipment.
What security-support information should I check?
Look for the stated minimum period of important security updates for the exact device. The National Cyber Security Centre also advises using a strong password and installing updates; check how the manufacturer provides them before purchase.
