@OverMyDadBody There are many different hardware versions of Deco X20 and your hardware version is not supported.

@OverMyDadBody Because Deco X20 does'nt support Device Isolation and because of that this feature disappeared from Deco App on Deco X50 because of compatibility issues some features are disappeared.

@Tiemen_NL You can use Cat6 or Cat7 cable to get better speed on satellite deco unit and how much speed are you getting through wireless backhaul?

@madhatter13 Have you unzip the file? You have to install (.bin) file on your Deco and directly installing (Zip) file is not possible.

@PHenry You can download the firmware from the link below and this firmware include all regions. Can you confirm your Deco region code which is mentioned on the sticker below. After updated to 1.2.0...
