I have this problem recently and yes I spend a lot of time searching for solutions and didn't avail any successful outcome. I hope that someone could help me here fix my problem. I am using a direct internet connection (No router, switch, etc) I use only the modem itself from ISP. This is very annoying because I need to disable and re-enable again the network adapter so that the 'unidentified network' will be gone. Yeah I'm doing that hassle routine everytime I power up my machine.
