I am not sure where's your problem:But
(1). Checking whether the DHCP server gave you IP address.There are 5-6 Steps before you can use it, you can get relative technical infomation on cisco CCO about Cable modem. It's very complexed.The most important information which will be helpful is recored in the Network managment software, It would record why the register process did not be finished, On which step it got a problem. But on client side, we can not get nothing about it. So contacting the technical support team.
