Split from this thread.
I just noticed today these phones coming and going in Network on Windows 10.
I too was perplexed and amazed to discover this thread when I did a search.
I checked my router but did not see anything there, but then noted that the 'property' of the a phone showed only a MAC address and no IP address, so my router had not given an IP address and therefore was not showing a device.
As the wireless only gets used when relatives visit as my network is wired, to double check that it was the wireless part of the router I disabled wireless - and no phones show up.
So, I am relieved, but -
I would like to understand why/how the device shows up in the Network window, what is the router passing to network computers, just the MAC and phone type?
Also, I tried my Android phone and it did not show up with or without a correct wireless password.
