I've had this sound bar and sub for a few years now, but for the life of me, the sub won't stay connected for more than a few mins. I've manually reset again and again; the light stays solid blue for a few seconds, then starts blinking blue... Then turns red. The bar and the sub might be 15 ft apart. I've tried moving the sub closer- same thing.
Honestly, I wish you could just manually connect (wired). BT is convenient, until it doesn't work. Is there a way to try a different BT dongle?
15ft may be quite a bit of distance. Try moving the subwoofer a lot closer then reinitialize the wireless transmitter.
