My Sonos keeps disconnecting — what do I check first?
Start with the boring one: Sonos speakers and your phone must all be on the same home network. If your phone is on the guest network, or on a different Wi-Fi name from the speakers, the app will keep losing them. Next, unplug any plug-in Wi-Fi extenders and see whether the problem stops — extenders are one of the most common reasons Sonos drops. Then restart the router and the speaker that drops most.
Same Wi-Fi name for phone and speakers; guest network off for Sonos; extenders unplugged as a test; whether it drops at the same times each day; whether it started after a new router, mesh or update.
If one speaker drops while others on the same network stay online, and the network checks above are done, contact Sonos support with a diagnostic submitted within 10 minutes of a dropout.

Check client history for the speaker's MAC address: which access point it was on, its signal at the time it dropped, and whether it bounced between mesh nodes. Reserve the speaker's IP address in DHCP before power-cycling anything.
Keep the hub on one Wi-Fi name for both bands. On BT and EE hubs, try changing the 2.4 GHz channel away from the one Sonos is using. Don't factory-reset the speaker until the network cause is ruled out.
A speaker that drops at the same times daily points to interference or a settings change, not a faulty speaker. Don't tell the customer to buy new Sonos kit until the network checks are done.
