Hi I have a Windows 8 laptop and up until recently I haven't had any problems with it; it has connected to the internet fine. But then about two days ago, suddenly, it will show that it has full bars and is connected to the internet but when I try to use Google Chrome or Internet Explorer, neither allows me to access webpages. I've tried using the Windows Troubleshooter but it doesn't seem to find anything wrong with my connection and when I do a ping test all 4 pings are sent/received. At first, the problem was just with my dorm's wifi but now my computer doesn't seem to be able to connect to the internet through any wifi router. Any thoughts as to what my problem is? Thanks!
