What to check before buying
Test the broadband connection and the Wi-Fi signal at the streaming screen before deciding whether to keep one router or add mesh nodes. If the service is sound but the signal weakens between floors, focus on coverage and placement; assess wired backhaul only if connecting nodes by Ethernet is practical.
Single router
Choose when: A suitably placed router gives the viewing screen a stable connection without persistent dead zones.
Trade-off: Floors and internal walls can still weaken the signal, regardless of the advertised Wi-Fi rate.
Mesh Wi-Fi
Choose when: Wi-Fi remains weak at the viewing screen after improving the main router’s position.
Trade-off: Nodes need suitable positions, and a larger or more obstructed home may need additional units.
| Concern | What to check | Who this matters to |
| Signal at the viewing screen |
Test stability where the screen sits, then note floors and dense walls between it and the router. |
I want the documentary to play reliably in a room away from the router, so coverage at that screen comes first. Around 42% of consumers would make floor-to-floor coverage their primary concern. |
| Other devices and backhaul |
Check broadband speed and simultaneous use; if Ethernet is practical, check the mesh system’s wired-backhaul support. |
When others are streaming, downloading or gaming, I need the network to serve the viewing room alongside their devices. Roughly 33% of consumers would prioritise capacity and backhaul for that reason. |
| Setup and expansion |
Check app and account requirements, compatible add-on nodes and what equipment must remain from the broadband provider. |
I would rather set up an expandable system than manage advanced network settings, especially if I need to adjust coverage later. Around 25% of consumers would put straightforward setup and expansion first. |
Brands and product lines to consider
These mesh families offer different approaches to coverage, wired connections and controls; none has a stated coverage figure that guarantees a signal at your viewing screen.
TP-Link
The Deco range is relevant if you want mesh coverage with the option of connecting nodes by Ethernet. The BE65 is a higher-capacity option for households that can use its wired connections.
- TP-Link lists four 2.5 Gbps ports and combined wired and wireless backhaul for the UK Deco BE65.
- Those model specifications do not establish coverage across a particular three-storey home, and one stream may not use its multi-gig capability.
Google
Nest Wifi Pro is an expandable Wi-Fi 6E mesh option for buyers who prefer app-managed setup.
- Google states coverage of up to 120 m² per router and up to 320 m² for a three-pack.
- Use those areas as planning figures, not a prediction for your floors and walls; check the model’s wired ports if faster wired networking matters.
eero
eero Pro 6E is an app-guided Wi-Fi 6E mesh option for households seeking whole-home coverage without extensive manual network configuration.
- Amazon’s UK eero Pro 6E listing states coverage of up to 560 m² for a three-pack.
- The listing describes advanced digital-security features as sold separately; check the terms if those controls matter to you.
ASUS
ZenWiFi BQ16 is aimed at households that can use advanced network controls and high-speed wired connections alongside mesh coverage.
- ASUS lists quad-band Wi-Fi 7, dual 10G ports and multiple SSIDs for the BQ16.
- Check whether you need those features and can position the units suitably; they are not required solely to play one documentary stream.
NETGEAR
The Orbi 970 line is relevant to large, device-dense homes considering dedicated backhaul and high-speed wired networking.
- NETGEAR lists quad-band Wi-Fi 7, enhanced dedicated backhaul and 10 Gig wired connectivity for the Orbi 970 series.
- Check the exact pack and floor-plan requirements before choosing this capacity for a single viewing screen.
Mesh systems on Joybuy
These three-unit mesh systems are relevant when Wi-Fi remains weak between floors. Compare node placement and wired-networking needs before choosing; a three-pack alone cannot establish coverage in your home.

TP-Link Deco BE65 BE9300 3-Pack
Consider this three-pack if coverage between floors matters and you can also use higher-speed wired networking. The listed variant is tri-band Wi-Fi 7; TP-Link specifies four 2.5 Gbps ports and combined backhaul for the UK BE65 line. Confirm the retail variant’s configuration before relying on those details, and test coverage at the viewing screen.

TP-Link Deco BE25 3-Pack
Consider this three-unit Wi-Fi 7 mesh system if weak signal across floors calls for additional node positions. Check the viewing room’s coverage and confirm the exact model’s wired-backhaul arrangements if you intend to connect nodes by Ethernet.

Common questions
How fast must my broadband be for a 4K documentary?
Netflix recommends a stable internet connection of at least 15 Mbps for one Ultra HD stream. That is an internet-service recommendation, not a guarantee of good Wi-Fi at the screen; other active uses also need capacity.
Does a three-storey house automatically need three mesh units?
No. The useful number and position of nodes depend on the layout, floors and walls, not the storey count alone. Ofcom notes that larger homes may need more mesh units, so test the viewing location rather than relying solely on a pack’s stated coverage.
Where should the main router or first mesh node go?
Place it as centrally as practical, off the floor and clear of obstructions. Ofcom advises that materials and nearby objects can weaken Wi-Fi; test the signal at the screen after changing its position.
Should I connect mesh nodes by Ethernet?
Ethernet backhaul is worth considering when cabling between floors is practical and the exact mesh system supports it. ASUS explains that its Ethernet-backhaul mode can leave more wireless bandwidth for devices; check your chosen system’s mode, ports, switch and cable requirements rather than applying ASUS instructions to another model.
What if streaming still buffers after changing the Wi-Fi equipment?
Check the broadband service, the connection at the streaming device and other active downloads before making another hardware change. For a provider-side service fault, Ofcom says the broadband provider is responsible for fixing it even if another company owns the underlying network.
