The farther your system is away from your router, the more buffering or "dropouts" may occur.
1 - Place your router as close to the system as possible.
2 - If needed, a Wireless Access Point can be added to the system to increase coverage and stability.
3 - 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.
