Strange Device on BT router using Wi-Fi - Unidentified

[randomuser2020]

Hi All - 

Ran this through a few people and i am scuppered... Spent a while tracking and tracing all my devices (OCD i know!) but i have one that i cannot remove and it has no IP address assigned... 

Ran the MAC through a database to see if it has a Vendor ID and try to find 'it' but comes up with nothing.. 

Anyone got any idea's here?

Do you have any powerline adaptors or smart devices that you may have forgotten about.

You won't be able to remove it while it is connected (green). You could try turning off the 2.4Ghz wireless to disconnect it, refresh the network map and if it turns grey delete it. Turn the wireless back on and see if it re-appears.
