Verifying the IP Address in Windows XP

To check the IP address:

1.On the Windows Desktop, click Start.

2.Select Run. The Run window is displayed.

3.Type cmd and click OK.

4.Type ipconfig and press ENTER to display your IP configuration.

If an Autoconfiguration IP address is displayed, that indicates possible broadband network problems or an improper connection between your computer and the SBG941. The Autoconfiguration IP address, ranging from 169.254.0.0 to 169.254.255.255, is reserved for Automatic Private IP Addressing (APIPA).

This can occur if the modem is configured to automatically obtain an IP address from a Dynamic Host Configuration Protocol (DHCP) server. When Auto-configuration is enabled, Windows will automatically assign an IP address if the cable modem gateway is unable to obtain one. Because this automatically assigned IP address is not valid, you will not be able to access the Internet using the cable modem gateway.

Check the following:

Your cable connections

Whether you can see cable-TV channels on your television

After successfully verifying your cable connections and proper cable-TV operation, you can renew your IP address.
