I have just moved into uni accomodation and cant seem to connect my speaker to the internet so i have been using bluetooth which worked fine until now where after 1 or 2 songs it will turn off randomly, i cant connect it to the internet to see if there is an update and have found no other answers online??
Curiously have you attempted to reboot the system by unplugging the power cord for a full two minutes, then plugging the system back in? Have you also tried another power outlet? Lastly, does this issue occur if you connect another device via Bluetooth such as another smartphone, tablet, or computer?
You can check the software version on the SoundTouch 20 by pressing and holding the number 4 and volume - on the top of the system until the countdown goes away. Then press the volume - button until the display reads "4.2 Firmware Version". What firmware version is listed there?
