  • Have now fixed an ethernet cable to our Vaillant sensoNET as WiFi connection was not good.
    Main router "connected devices" shows the unit is attached both on LAN and WLAN, but the phone app can not connect.
    Thought I'd try a fresh install and select LAN as the connection, but despite uninstalling and reinstalling and clearing cache and powering off/on unit and boiler both LAN and WLAn connect. How do disable the WLAN now i have LAN? Thanks Submitted on 19-11-2022 at 13:20
