Thanks for your reply, I assume this is set up on the router and not via the TV?

Thanks for helping me out, I'm at my wits end, after months of putting up with all the problems like everyone else and to then have the system working after the update only to now experience stability and connection problems is depressing to say the least 😞


As per Glimm's post. My setup is on 5ghz. I had similar issues when I was using a netgear router and I had to use the Samsung 5ghz hub to get the system working reliably. I now have a Bt smart hub and it's very stable. In regard to switching the system on. My soundbat comes on as soon as I switch in my TV. I'm pretty sure you have to enable this function on the soundbar. I could be wrong though.


Thanks Lee,

I'll give that a try 👍

The channel for Wi-Fi is something you configure in your router.




I am sure you have been mistaken for a Samsung moderator before hehe


Must have an air of authority in your posts :smiling-face: 

Haha. Well...

Apologies for the short reply. I was in my car and thought that a quick and short reply was better than a lengthy one that ended abruptly :smiling-face:


But the Wi-Fi channel is something set in your router. 

And if your router has both 5G (AC) and 2.4G then this is separate settings.

The soundbar and rears have proven issues if you use a channel for 5G outside the range of channel 36 to 48.

If you use 2.4ghz Wi-Fi then the channel used is of no problem.


To verify what channel that is used use the multiroom app or a Wi-Fi analyzer app of choice. 


If you want to switch from 5G Wi-Fi to your 2.4 then you will have to repeat the connection procedure on each device and select the 2.4 instead




Hi Robbie


Yes I think I did, you're right.  Lol. Have you decided to upgrade the firmware on your TV or not mate? 



HI Lee


I have decided after sleeping on it (and having a nightmare about this all starting again) to turn off auto update on tv and soundbar and not up date again now. 


No point in updating as I have no issues with how it sounds or operates at the moment. 


It's even powering correctly with TV standby now so happy days :smiling-face: 

I think that's the way I will go too Robbie. It's all working great now so I'm not going to mess with it.


1180 takes away hdr notifications except for tv's amazon prime app. Supposedly 1180 adds uhd support for tv's VUDU app but mine still only shows hdx. Tv's picture settings still automatically adjust when hdr content is playing.
