Doubt it, Windows trys to see what you are connected to by sending packets and other commands and see if the devices respond. But it isnt always correct. such as on my system it shows a hub and then a switch before it gets to the router, where instead the one I used was in vmware, there isnt any hub or switch for it but it thinks there is since it is another connection node before it gets to the internet.
In your case windows is simply seeing another node that doesnt respond with what it is. So it just says unknown.
