Just a quick tip, if you open up a browser (and ARE connected to the internet) but seem to be getting timeout or unreachable errors on any site you go to. Do a quick check and see if you have Malwarebytes installed. This program more than likely is causing that issue.
Why? Well, it tries to act as a proxy server and "scan" your traffic to make sure it is safe, but the huge downside is it can make things stop working. Do yourself a favor and just remove it.
