Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Type — mains WiFi stereo speaker
- A compact mains-powered WiFi speaker (stereo, not Atmos — that is the Era 300). Streams over WiFi via the Sonos app, plus Bluetooth and a USB-C line-in with an adapter. A pair can be rear surrounds for a soundbar.
- WiFi-first
- Primarily WiFi through the Sonos app; a missing speaker is usually a network issue. Bluetooth is a secondary direct option.
- Stereo pairing
- Two Era 100s can be grouped as a stereo pair (one left, one right) — if only one plays, check the pair grouping in the app before suspecting a fault.

Exact questions
Questions that only have an answer for the Sonos Era 100 speaker
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
Only one of my paired Sonos Era 100s is playing.+
When two are bonded as a stereo pair, one plays the left channel and the other the right, so a mono source or one speaker dropping off WiFi leaves a single side. Check both are grouped as a stereo pair and online in the Sonos app, and test with a stereo track. If one keeps disappearing, it is a WiFi/network issue for that unit rather than a speaker fault.
Structured depth, not empty permutations
Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.
