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.

Verifying the IP Address in Windows Vista

Do the following to verify the IP address:

1.On the Windows Desktop, click Start.

2.Click All Programs.

3.Click Accessories.

4.Click Run to display the Run window.

5.Type cmd and click OK to open a command prompt window.

6.Type ipconfig and press ENTER to display the IP Configuration.

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