Will multi-room audio work properly in a flat or apartment?
The answer
Speakers that have to find each other, not just the internet. 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 multi-room audio need from the network
- • One Wi-Fi name for the whole house
- • No client isolation
- • Multicast/IGMP snooping left in its default sensible state
Mesh considerations
- • Wired backhaul between mesh boxes helps enormously.
- • A speaker that is fixed in place can cling to a distant mesh box — power-cycle it once the mesh is settled.

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.

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)
