The Boost is up to twice as powerful as the Bridge and offers top-notch wireless performance. This means you can enjoy unparalleled reliability even in challenging wireless environments. Sometimes, the Wi-Fi at home just isn't stable. Other times, too many devices compete for bandwidth, crippling the entire network. And sometimes, it's simply difficult to transmit the signal to distant rooms. If any of these Wi-Fi issues sound familiar, the Boost can help you stream music flawlessly through your Sonos system. The Boost creates a separate network just for Sonos, allowing you to enjoy music without interruptions throughout your home. By establishing this separate network, the Boost eliminates interference from other devices connected to your Wi-Fi. The Boost features three internal antennas that transmit in all directions—even through walls and ceilings. This ensures that music reaches every room in your home, no matter how far apart they are. Just plug it in, connect it to your router using the included Ethernet cable, and set everything up through the Sonos app. Done. You don't necessarily need a Boost for your Sonos system, but it's good to know it's there if you need it.
