La Crosse View App: Will this unit connect with a new 5 GHz Wi-Fi router?

Yes, this display will work with any Wi-Fi router meant for home use.  All 5GHz, Dual Band, Mesh, 6.0 and other WiFi routers also support 2.4GHz WiFi.  The display will use the 2.4GHz band to connect with the router.  This process will work on this model even if it’s a Mesh router and if the 2.4GHz and 5GHz bands use the same SSID (network name).  The 2.4GHz band is actually preferred for low data use devices like the weather display as it will have longer range and coverage to more places within the home.  Open the La Crosse View App and Select Menu -> Connect Wi-Fi and the App will guide you through the Wi-Fi configuration process.
