I'm having some trouble with a device on my network. All devices that are shown have complete info as to who or what they are and can be deleted except for one. This one comes up as "Generic" and is online. It has no ip, no information, mac address or anything and I am unable to get rid of it. I know all the devices on my network except this one and dont have any other devices that would be connected either. What could thos be? Any suggestion as to what i should do about it?

    I am literally pulling my hair out dealing with this same exact problem... coincidentally, it just started very late last night/very early morning... I’ve been trying to remedy this issue for hours and so far nothing has worked.. sigh  :s

    Can you at least block said device?

    Yes, Reee, its very frustrating.

    As to Lee_Bo, no, i cannot block or delete the device.

    An Q101, that's an awesome suggestion but unfortunately no information is given with the device other then it is connected and on line.

    I’m having the same issue. I have 2 rogue devices on my network with 0 info. About them. Can’t delete them. Can’t find out any info about them.

    Same here, I’ve had some 5E:D0:D0:99:CF:FA device on my network for a few days, I’ve blocked it but I have no idea of what it is. My passwords are too complicated to consider being hacked as a high probability. All iOS 14 devices are set already not to use the private MAC address feature. Don’t know what to do if not pulling the plug on everything and see what happens.

    Most probably just a Fing database and/or display issue.
    Nevertheless, in all eventualities, devices with no IP address can sniff your network, communicate using a point to point protocol but cannot directly export anything outside (Internet). Try using a network sniffer like Wireshark to see if there is any PPPoE protocols running around. You may not see any established connection, if any, but a PPPoE connection initialisation starts with a Ethernet broadcast at the MAC address ff:ff:ff:ff:ff:ff, the source MAC is the PPPoE source.
    If you can't explain it simply, you don't understand it well enough.
