Troubleshooting 8

This chapter contains a list of problems that may be encountered while using the Gateway, and techniques to solve them. Note that these techniques may not be suc- cessful in all cases. Also included is a list of frequently asked questions.

Troubleshooting

Cannot Use the Internet

Physical Connections

Ensure the Gateway’s Power light is on, as well as the appropriate lights for any active connections (Ethernet or USB). If the connection is not active, reconnect the appropriate cable.

Connection to the Router

Check that the default IP address the computer is receiving is correct by select- ing Start, Run, typing cmd in the “Open” text box, then typing ipconfig. The IP address should be 192.168.0.x (with “x” representing a number from 2 through 254), and the Default Gateway address should be 192.168.0.1. If not, restart the computer to allow the Gateway to assign a IP address. If a static IP address was previously assigned to the computer, it will need to be removed before the Gateway can dynamically assign a new IP address. After the computer restarts, check the IP address of the computer again. If it is still not correct, type ipcon- fig /? (note the space after ipconfig) to receive an explanation about how to release and renew the IP address.

Once the IP address has been verified as correct, open a Web browser. In the “Address” text box, type 192.168.0.1 and click Go. The Gateway’s Web Configurator Main Menu screen appears, verifying the Gateway’s active connection.
