hi ron, i was able to dig some more details.
the one i have is RCA (by thomson), model DHG535-2 H/W: 2.0. This seems to be the manual: http://www.thomson.net/SiteCollectionDocuments/Products/User%20guides/Cable/modems%20and%20gateways/US/userguide_dhg%20%20535_en_092007.pdf this modem (newer than the one for which i had read the manual before) too seems to have those features i mentioned. so i was able to reach the UI via http://192.168.100.1. hope this helps. regards dharani On Wed, Nov 5, 2008 at 10:28 PM, Tharaneedharan Vilwanathan <[EMAIL PROTECTED]> wrote: > hi ron, > > isnt cable modem a router too these days? i remember reading a manual > in the internet for a cable modem (provided by comcast) that had the > ability to act as DHCP server to the client side, NAT, (it had web > based UI too), etc just like a Linksys box so that you only need a > switch to connect multiple PCs.
