I have received my Surface 2 yesterday and began playing with it, it is an awesome tablet. I was able to connect to my home WiFi network and surf the internet but I am unable to join the HomeGroup network to share files and use the printer. Tried several times using the HomeGroup password, adjusting the time (synchronizing), activating the IP Home service on the host computer, none has worked. Does anyone have any tips on how to join the HomeGroup network? I can see the surface 2 on the HomeGroup network map (Windows 7) but it shows the Surface as an external device (not joined).
