I am having an issue with my home machine where Windows 7 seems to be adding a 2nd (Public) "Unidentified Network" which randomly appear sometimes on startup and makes it impossible for me to connect to the internet. At times it is not there, and I only have my original "Homegroup" network which does allow an internet connection. If I shut down and power-cycle the modem & router--sometimes 2 or 3 times--eventually the Unidentified Network goes away and everything works fine.
I have tried to delete this network when I see it but it does not show up on the list.
Any ideas would be much appreciated.
