When this guide applies

Repeated Bluetooth interruptions or poor reception, not a WiFi streaming complaint.

Connection scope: Bluetooth. Symptom: Audio keeps cutting out.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.

Checks and possible outcomes

Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

step-0

Is Bluetooth the active audio source?

WiFi playback can pause Bluetooth without a radio fault.

Look for: Confirm the stated prerequisite or observation; unknown is not a fault diagnosis.
