For ages now, even after several reboots, an unknown device with all zeros for a MAC address and a permanent static address (even when I try to turn static off it jumps straight back on) has been showing up on my routers Network Map attached to LAN port 1, even when nothing is connected to the port. Its always displayed as 'Not connected' but when I try and delete it with the 'Delete device' button nothing happens.
Any ideas?
Fixed! Go to the fix.

@DangerDonna Could it be the Plex? Wild suggestion, and may be totally wrong.

Try changing Always use this IP address to No, followed by Apply.

Thanks for your reply
I've tried changing that to No several times and applying but every time it reverts to Yes.

What do you mean by reboot? If you mean just powering off then try a factory reset by pushing a pin in the rest hole. Keep the switch closed for about 30 seconds then leave it to configure itself from scratch. This can take 10 minutes so be patient.
If that doesn’t work then it could be a faulty hub.

Thanks, I'd done a standard restart before however I did a full reset and the mysterious device has disappeared.
