HD Wireless Speakers (WiSA) - Wireless Router Interference
Models Covered: RP-140WM, RP-440WC, RP-440WF, RP-HUB1, RP-110WSW
In some cases wireless routers can cause interference with a WiSA system. One fix for this is to configure your router (both 2.4 ghz and 5 ghz) to a fixed channel instead of using the default "automatic" setting. In most cases there will no longer be drop-outs after this.
It is also a better idea to not have your wireless router setup in your entertainment center with all the other equipment. If you need to wire multiple devices in your entertainment center, it is better to connect your equipment to a network switch and then connect it with a network cable to your router.
