Will televisions work properly in a flat or apartment?
The answer
Big screens with surprisingly ordinary Wi-Fi. In a flat or apartment, the building itself is usually the deciding factor: dozens of neighbouring networks on the same channels.
What this building does to Wi-Fi
- • Dozens of neighbouring networks on the same channels
- • Concrete floors and ceilings
- • Entry systems and shared risers
What to do about it
- • Congestion, not distance, is usually the problem here
- • Use the fast band where you can — fewer neighbours reach it
- • One well-placed router usually beats a mesh pack in a flat
What televisions need from the network
- • 5 GHz within range for 4K streaming
- • Casting traffic allowed on the network
Mesh considerations
- • A mesh box with a spare Ethernet port near the TV lets you cable it — better than any Wi-Fi tweak.

If the free fixes don't do it
Only worth reading after you've tried everything above. Nobody pays to be listed and we don't rank kit by commission.
- Deco X50 (3 pack) — The most forgiving mesh for a normal brick house. One Wi-Fi name, and it takes a network cable if you can run one. (around £180–£220)
See prices - eero 6+ (3 pack) — Easiest set-up of the lot and very stable, but you manage it entirely through the phone app. (around £170–£230)
