How do I get Sonos to work properly with a BT Smart Hub?
The BT Smart Hub works with Sonos, but two of its habits cause trouble: it can steer devices between its two Wi-Fi bands, and its default channel can sit right on top of the one your speakers use. Giving your Wi-Fi a single name for both bands and picking a quieter channel fixes most BT–Sonos complaints we see.
Single Wi-Fi name (not split 2.4/5 GHz names) or all Sonos on the same band; hub's 2.4 GHz channel moved off Sonos's channel; speakers not on the BT guest network; whether dropouts began when the hub was replaced.
If speakers vanish only after hub firmware updates, note the date and hub model and raise it with BT; the pattern is worth logging as a case even if you solve it with a channel change.

Set the hub 2.4 GHz channel to 1, 6 or 11 — whichever is quietest — and keep SonosNet (if used) at least one clear channel away. Confirm in telemetry that each speaker holds a steady association rather than flapping between bands.
In the BT hub settings, turn off 'Smart Setup' prompts if they interrupt devices, and avoid splitting the bands into two names unless you can pin every Sonos speaker to one of them.
BT Complete Wi-Fi discs make a mesh — Sonos should connect through the discs, but a speaker wired to the hub while discs broadcast can create loops. Only wire Sonos when SonosNet is intentional and STP-safe.
