Verifying The Ip Address In Windows Vista; Renewing Your Ip Address - Motorola surfboard SBG901 User Manual

This can occur if the SBG901 is configured to automatically obtain an IP address from a
Dynamic Host Configuration Protocol (DHCP) server. When Autoconfiguration is enabled,
Windows automatically assigns 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, see
