RBR850- Sony HT-ST5000 interference

I have the RBR/RBS850 Orbi system as well as a Sony HT-ST5000 wireless soundbar. The same issue is described in the link below. Is there any other suggestions? I live in an apartment complex and setting the soundbar to the lower frequency also causes issues. I am trying having the WiFi set to 50 percent and changing the soundbar to different channels in the 5.2 GHz range, but keeping the soundbar in this lower frequency tends to cause issues with the wireless connection to the subwoofer.

netgearIt would be nice it you would finally support the option to change the backhaul frequency. It appears that it does it in different regions, but alas, you guys locked it in the US to a higher frequency that other devices utilize as well. The previous solution was to set the frequency to 108 for the backhaul utilizing telnet, but I get that you guys may not want to allow telnet to be enabled. At least allow for the backhaul to be changed. I don't think some of these frequencies, like 108, are restricted in the US.

I am trying to see if reducing the power works. I also put the 5 GHz Channel to 48  and the soundbar to 5.2 GHz (Channel 2) hoping that both things will help keep a stable connection on the soundbar and subwoofer. For reference, the soundbar has 6 Channels, 5.2 GHz (Channel 1,2,3) and 5.8 GHz (Channel 1,2,3) and I couldn't find any documentation to see what the exact frequencies are. The 3 Channels on the 5.8 GHz have interference caused by the backhaul, and the 5.2 GHz is congested due to the WiFi operating at similar frequencies. Not just mine, my neighbors which I can't control. The soundbar is updated to the latest firmware.

I see this breakdown of frequencies, but am curious why the backhaul can't operate on a DFS frequency. Doesn't the backhaul utilize DFS (Mine uses 157 +1 after figuring it out with a Signal Analyzer) to minimize interference?

Do you have any other suggestions while keeping the same products? I have been searching the forums for other solutions. I previously had the RBK50 and was able to go into the router through Telnet to make sure that there is no interference. The Orbi system is probably the most stable WiFi system I have ever used and its disappointing that there is one part of it we cannot configure.,

netgear  Please take a look at letting people configure the router, or at a minimum, the backhaul so when we have devices that interfere, we can configure our products for our use cases. Disabling Telnet and not allowing SSH severely limits what we can do to your programmed functionality.
