Check your Internet connection
            Check any cables and reboot any routers, modems, or other network
                devices you may be using.
        Allow browser to access the network in your firewall or antivirus
            settings.
        If it is already listed as a program allowed to access the network, try
            removing it from the list and adding it again.
    If you use a proxy server…
        Check your proxy settings or contact your network administrator to
            make sure the proxy server is working. If you don't believe you should
            be using a proxy server:
            Go to
            the menu >
            Settings
            >
            Show advanced settings…
            >
            Change proxy settings…
            and make sure your configuration is set to "no proxy" or "direct."
