This topic has appeared here before and I have tried all the recommendations around reseting the speaker. I am convinced this speaker is meant to only reliable work with wifi. Can someone from Bose confirm this. I use this speaker in my home with no issue but also like to use it in my car. While there are issues periodically at home with the speaker turning off, they pale in comparison to the constant cutting off/disconnecting (I am not even sure if there is a manufactured distinction between the two). In the car it varies from occurring after 3 seconds to after 30 minutes of playing music (with full battery). The speaker is all but unusable in the car. The only reason I paid the +$300 for this speaker is the issues that plague bluetooth speakers in general led me to believe this would not be an issue with Bose especially considering the price tag. This is my 3rd bluetooth speaker brand attempt and have yet to find one that works beyond the 6 month mark.
