Method 4: Device is not in range

To make sure that you get the best listening experience using this Bluetooth speaker, the device it is connecting to should not be more than 100 feet away. This range will decrease if there are a lot of obstructions or signal interferences such as walls or radios between both devices.

Try moving the speaker and device it is connecting to closer then check if the problem still occurs.

Having connection issues on a Bluetooth speaker can be a frustrating experience. Hopefully, this solution will help you fix the problem.
