You need to make sure your DNS servers are listed by the sounds of things. If you can ping an external IP address, you have a connection.
If you use WindowsXP
Right click on properties of the network card and check the Status Option.
Goto the "Support" Tab and you should see a button labelled details. Hit this and you should be able to see if your modem forwarded the configuration to the network properties.
If the DNS servers are empty, just right click on the Network adaptor and hit Repair. Also, make sure that in the networks property page, on the TCP-IP section, make sure that Both "Obtain and IP address automatically" and "Obtain DNS Server automatically" are both selected.
Reboot Cable modem, and let it restart. Once the ONLINE light is stable, reboot your PC.
EDIT** Did you actually get 4 packets back on the external ping?
Is your Cable modem online light stable, or does it look like its rebooting constantly?
