A Sonos Era 300 reset is the step to take when the speaker will not connect, has a stuck light, will not join the app, or you are giving the speaker away, and the right reset depends on how far the problem goes. This is a mains-powered Wi-Fi speaker with Dolby Atmos drivers, Wi-Fi 6 and Bluetooth 5.3, and it stores your Wi-Fi details and its place in your Sonos system.
The checks in more detail
Most faults are cured without the full factory reset, so move through the levels in order. Start with a power cycle. Unplug the Era 300 for ten seconds, plug it back in and wait for the light to show it is ready; this fixes a surprising number of problems. If the speaker is not found by the app, restart the app and the router, and check that the phone is on the same Wi-Fi.
If the speaker's light shows a Wi-Fi problem after you changed the router, you can reconnect it to the new network through the app's settings, a lighter step than a reset, which keeps the speaker in the system. If the problem continues, do the factory reset. Sonos describes it as unplugging the speaker, then holding the Join button on the back while plugging the power in, and keeping the button held until the light flashes orange and then white, then releasing it.
The speaker restarts as new and appears in the app ready to be added again. Do this also before selling the speaker, after removing it from your Sonos account in the app. The reset removes your Wi-Fi details and settings, so you will add it again, and Trueplay tuning must be repeated. A speaker that does not respond to a reset, or whose light stays orange, may have a hardware fault, and Sonos support can help with the serial number. Keep the speaker unplugged during any step that says so.
