@pawelb Have u checked on different devices? When (FT) disappeared from your Huawei Mate 20 Pro.

@Olivertye What's your hardware version V1 or V2 ?

@PhilA65 Update it by using Recovery Mode.

@HelpFixDecoApp I think my issue is fixed after i set static ip address of Ethernet Backhaul Deco Unit in my Main Deco Unit. I will let you know in few days. @David-TP

@David-TP What about DHCP Server DNS ?

@David-TP When i reboot Main Deco only then the ip conflict occured or when i only reboot Ethernet Backhaul Deco unit also ip conflict occured. And yes ethernet connected devices like HikVision DVR...
