I'm concerned because Windows 10 network page keeps showing weird devices I don't identify as mine. I want to know what they are and if they represent a security thread.
I have already read this question but is not fully related
For instance see these images below
Comments:
- They never show their IP addresses, only MAC addresses (communication at data link layer?).
- They don't appear as connected on my Router (it seems only to displays MAC for devices with IP addresses )
- If I block the MAC address on my router they go away but something else appears with a different MAC
- I have already changed the WIFI password (not the SSID) and they keep reappearing
- Sometimes my Samsung Smart TV appears displayed using the same pattern (no IP only MAC) but I do recognize this device. Although I don't know why this happens if the TV is off (Samsung spy!). In addition the TV does not know the new WIFI password
- I don't have Ethernet connected devices on the Router
- I have tried to look for the vendors or IDs of the devices MACs and not too useful information has been found (besides I know it is possible to change your MAC to whatever you want on a lot of adapters so to me this is not too useful)
- I can't hide my SSID or use fixed IPs because I have one WIFI connected doorbell-camera that is not advanced enough to handle networks that don't broadcast SSID and I don't have a way to make it use a fixed IP
- My Router doesn't have the option to disable WPS which seems to have been the solution here
