Bluetooth interference.

Hey there TX Chojin,

I'm sorry to hear about the issue. Since this thread is pretty old, I would suggest creating a new thread detailing what you're experiencing and any troubleshooting steps you may have tried. This way you can receive support catered to you from our community.
Thanks in advance!

first of all the instant-on option shouldn´t even exist. its pure energy wasting...

to get to the topic, i have the exact same problem with the soundbar disconnecting randomly to the lg subwoofer.

i connected the soundbar via optic cable and the problem started just recently

i try´d everything, my xbox is always powered off and im using lan cable offcourse. just like you said, the xbox
is the problem, because the soundbar works perfectly once the xbox turned off.

sometimes it works flawlessly. what i did is turned the wlan router channel from "auto channel" to channel 7 (or whatever channel is best for you) then you power on the soundbar and wait a few seconds till its connected to the woofer.

after that, power on your xbox and watch your "lg soundbar display". while the xbox is in boot process it shouldn´t loose the connection between your soundbar and the woofer. if so, then its not going to work.

if you solved the issue permantly, give me please a heads up. i know the thread is old by now but the problem still exists out there...

sry for my bad english

Yea, this is an absolutely unacceptable answer. I have numerous other wireless devices in my home (a PC, three laptops, several tablets, several mobile phones, a wireless access point, two chromecasts, other game consoles, not to mention other household
products such as a microwave) and NONE of them cause interference with each other or with my speakers. The fact that the xbox is causing this problem is mind-blowing given the expense of the device and it's relative complexity, and the fact that NOBODY from
MS is here to offer a solution is disgusting.

It happens in both instant-on and energy saving mode. That is also something that I tested. It also happens whether any controller is connected or not, which is why I think it is a regular beacon being sent by the console any time it is powered on.

Is this happening in instant on mode or also if in normal stand by? As bluetooth is working in the 2,4 GHz band and also does the xbox one controller it may be an interference between the controller and your soundbar. Be sure it is not an violation of the
FCC as the 2,4 GHz is regulated but not bluetooth exclusive.
