Telecable Internet: Modem question

I don't have telecable, so I'm looking for some info: does anyone here know how to get into the modem software? Like, 192.16.1.254 access. I want to install Unblock-US through the modem, not through the ethernet settings on the individual computer. This is the only way that the wireless will catch the U.S. IP address, as far as I know.

I can do this with any TelMex modem except for the current Tecnicolor modem they use (which is a piece 'o crap anyway). But I have no idea if the DNS addresses are accessible in the TeleCable modem.

Telecable provided a scientific atlanta modem. This is what I use to access the modem:

http://192.168.100.1/

However, to my recollection this does not give you total access for tweaking the modem.

Thanks, papa. I'll see what I can uncover.
