Unidentified network?

[cloudxcrash]

Yesterday my internet randomly went down when I was playing Dragon Nest. My previously connected internet connection changed to "unidentified network" and now it won't find a valid IP address. Anyone ever had any similar issues and/or knows how to solve this?

Edit: I tried simple stuff like restarting, ipconfig /release and /renew but haven't had any progress.
