My BT Smart Hub Manager shows a number of WiFi devices which I do not recognise connected to my network. Their icons are green, so I cannot remove them. Four of them only have a MAC address shown (no IP address and no device name), and 0B traffic both up and down. Searches for their OUI addresses return no results. Can anyone shed any light on what they might be and how I can get rid ofthem ?
One other reported device does have a DHCP IP address, and does have some traffic shown. Again, MAC and OUI searches reveal nothing.
One other question - what does the "D" mean on an icon, and why isn't it explained at the top of the screen along with the port forwarding and access control tags ? I have found old discussions about it, but no definitive answer.
