Dell Inspiron 7559 No internet connection at all

I have some problems with my dell Inspiron 7559 in the last days, I upgraded it with a 250GB on the m.2 slot and reinstalled windows 10 and all the drivers. It worked like a charm until now when it connects no problem both on the ethernet connection and on any wifi network. But there is no internet connection showed in any browser i have tried. I also tried resetting the drivers, installing the newest ones, older ones, and all the tricks in the book I know of. Do any of you had the same problem? I need this for my university work and can't use it without being able to connect to any network.
