The farther your system is away from your router, the more buffering or "dropouts" may occur. So we recommend that your router be as close to the system as possible.
If needed, a Wireless Access Point can be added to the system to increase coverage and stability.
Additionally, we highly suggest setting up your Polk Omni SB1 Plus sound bar and two Play-Fi enable rear speakers (ex. S2, S2R, S6) on the 5 GHz band of your router or access point.
5 GHz is faster than the 2.4 GHz band and we've found it to be more stable in this environment.
