No internet through SB4200 cable modem

I installed a SB4200 cable modem that I bought used but in great condition.
The modem does everything ok (as far as lights etc..) and my PC seems to ping
ok. IPconfig reports an IP address and subnet mask address but no default
gateway or connection specific DNS.
How can I further check the cable modem?

Call the cable company?

You might have to call your cable company and register the new modem
with them.

It seems that you are correct. The bad news is that my provider (Time
Warner) wants to charge me another $45/month for each additional account in
my house! They originally told me I could have up to three IP
addresses/accounts in my house for the one fee; and they told me that I could
buy additional modems and just plug them in, but now they have changed their
story.
I feel like I was ripped off, do you know if this is a typical policy among
cable vendors?

I thought that you were replacing an ISP-provided cable modem with the
one that you bought. Cable ISPs typically let you use your own cable
modem, and it saves a few dollars per month over renting a cable modem
from the ISP.

Do you want to use more than one cable modem? I've never heard of
such a setup, and I don't know what a typical policy would be.

Some cable ISPs let you have more than one IP address through a single
cable modem. There's typically a fee of a few dollars per month for
each additional IP address, but it's much less than $45 per month.

Multiple IP's on a single modem. You do NOT get to connect as many modems as
you like. You get billed seperately for each modem. This is normal.
