I can't get an internet connection on any browser but MSN.
MSN is a website and not actually a browser, so I'm guessing that you are actually saying, Microsoft's new Edge browser works but not Mozilla Firefox nor Google Chrome.
How about Internet Explorer
C:\Program Files\Internet Explorer\iexplore.exe
Does that work or does that one also fail?
What third party security suite software do you have installed on your computer?
Avast, Avira, AVG, Comodo, McAfee, Norton, Vipre, Zone Alarm, etc., etc., ??
