Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer REAR DISCONNECT Error Fix: Rear Speakers Intermittently Drop Connection

Error code REAR DISCONNECT on the Samsung TV & Audio HW-Q990C 11.1.4 Channel 546 Watt Soundbar with Dolby Atmos, DTS:X, and Wireless Subwoofer means: Rear Speakers Intermittently Drop Connection. One or both rear speakers randomly disconnect during playback — surround audio cuts out then reconnects. The wireless link between the soundbar and rear speakers operates at 5.8 GHz. Causes: (1) 5 GHz Wi-Fi router too close to rear speakers — move router or rear speakers, (2) distance too far — keep rear speakers within 15-20 feet of soundbar, (3) physical obstructions between soundbar and rear speakers (large furniture, walls), (4) other 5.8 GHz devices interfering. Re-pair using ID SET button. Position rear speakers with clear line of sight to soundbar. If one speaker disconnects more than the other, try swapping their positions to identify if it's location-dependent or speaker-specific.
