Q 2. I can connect but am unable to use the internet?
A. Check for the following
2.1 Try Disconnecting and reconnecting to the internet.
2.2 Do you have a firewall installed? Typically firewalls will block all newly
installed networks (Please refer to the documentation provided with your
firewall software to unblock your PPP connection).
2.3 Check that your connection settings under internet options are setup
correctly (see image below). The internet options can be found under the
control panel in the windows operating system.
2.4 Check that your computer is not infected by a spyware or a virus. Make
sure that you have a spyware/antivirus software installed and is updated
with the latest definitions.
2.5 Check with your ISP the current status of their network, generally if there
is a problem on the network the ISP will have an automated message
playing on their technical support call lines.
Q 3. The internet worked fine but has stopped working now?
A. Check for the following:
3.1 Is the phone cable securely connected to the phone jack and the modem?
3.2 Have you installed firewall software recently? If yes then make sure that
the firewall software is not blocking the PPP connection (Please refer to
the documentation provided with your firewall software to unblock your
PPP connection).
3.3 Please make sure that the connection settings in your browser have not
been changed (see section 2.3 of the troubleshooting section).
