Decora Smart® Wi-Fi Bridge (MLWSB) has two connections. A Wi-Fi connection to the internet and individual connections to each DN Switch or Dimmer. For information on connections and coverage area see the article How Many Devices Can I Connect To A MLWSB And What Is The Wireless Coverage Area?
Each DN switch or dimmer can display the connection strength to the Wi-Fi Bridge (MLWSB). If you have multiple DN devices and cannot find a location to provide a good connection for all of the DN devices, see the article If I Have Multiple Decora Smart® Wi-Fi Bridges (MLWSB) How Do I Connect To The Bridge With The Best Signal?
To review the signal connection between the Wi-Fi Bridge (MLWSB) and DN Switch or Dimmer:
Press the 3 dots is the upper corner of the DN Switch or Dimmer
Choose Device Settings
Choose Device Health
The Device Signal Strength is displayed in the Device Health screen. If signal strength is low, the bridge should be moved closer to the DN switch or dimmer.
