Model: Deco M5  
Hardware Version: V3
Firmware Version: 1.5.1

I've recently had a notification that a new device has connected to my Deco network as 'UNKNOWN' with an invalid MAC address of 'AE-C7-55-80-9F-E7'. 

 

I've blocked/blacklisted it, but I'm intrigued as to why it appeared randomly with an invalid ID.

Hi, thanks for your patience.

Have you checked if there is one of your home devices?

For some mobile devices, they supported private address and could change its MAC address and make Deco recognize it as a new device;

For example on the IOS14: https://www.fing.com/news/private-mac-address-on-ios-14

 

Thank you very much.
