A high percentage of connection issues that occur when you have an internet connection but can't get a browser to hook in is due to firewalls. If your browser won't connect, first try disabling any firewall (you should never have more than one firewall on your computer) and then check for ability to get browser to hook up. If that doesn't work, then remove your firewall from your computer. If it won't uninstall, then remove it manually. Directions on manual removal of firewalls are available on the internet. I recommend addressing the firewall issue first before examining other possibilities.
