i have HW-Q90R soundbar with latest firmware 1010.5 (same problem on 1008)
I also have Orbi RBK50 system with RBS50 and RBR50
when the Orbi router is on by itself - no problem
when the Orbi satellite is on by itself - no problem (but obviously no internet)
once the router connects to satellite - there is interference
The interefernce causes the subwoofer to have crackles and drops (i.e. becomes silent) for a second or so, very often, (Every 5-10 seconds as soon as i turn off either Router or Satellite the crackles go away.
i've uesd telnet to change the wireless backhaul channel - the only one that works is 50, it fixes it for awhile. Then the crackles recur. I'm not sure what triggers it to recur. Interesting, when changing to channel 50, i can't the hidden channel reflected on a channel analyzer app on android.
The system is such that
ORBI router -----------5m -------- soundbar --------5m----------- ORbi satellite
they're about 5m apart. Defnitely can't be futher apart.
The soundbar and subwoofer is literally 30cm apart
seems like the wireless connection between the 2 orbi is interfering
really not sure what else i can do to fix this problem.
I've tried to re-sync the woofer and rear speakers
Is there a way to change the frequency channl to which the soundbar communicates?
There does not appear a way to hardwire the subwoofer.
(it's hard to appreciate if there is disrutpion to rear speakers are they are not constantly on)
I recommend reaching out to the manufacturer regarding this.
The orbi backhaul is causing the interference. The soundbar used channel 165 ish (5.8ghz frequency) to communicate with the sub. When I did telnet, I found out my backhaul was using channel 161 and after changing the backhaul channel to 100, I haven't had any issue since.
