Help with Motorola SB5120 Hose A. Cuervo 01-16-2006

I just purchased a SB5120 and registered it with my ISP.
Seems to work fine so far, but I'd like to configure it
just a little.

After browsing through the web interface (which is not
even protected by a password), I found that all you can do
is: 1) reset the modem to defaults, and 2) reboot it.

So I'm jumping through hoops with Motorola tech support.
After telling them that there's nothing in the web interface
that will allow me to change things (like LAN IP, shut off the
DHCP server, set a password, etc), their answer was this:

"There are no changes that can be made in the configuration
menus of the SBG5120 Cable Modem other then resetting the modem."

Uh... yeah, no kidding. I think that was my question in the
first place.

Does anybody have info on configuring the SB5120, or do I
need to return it for a refund ?

Thanks :)

If those are the only two alternatives you'll accept, I believe you'll
need to return it.

>Thanks :)

Glad to help.

If those are the only alternatives the OP will accept, then the OP needs
to abandon broadband internet. See Warren's post in this thread.

Let's alter that quote just a little to make it clearer:

"There are no changes that can be made BY END USERS in the configuration
menus of the SBG5120 Cable Modem other then resetting the modem."

Changes to the modem configuration are made by the owners of the network
that it is placed on: That is, the cable company. A configuration file is
downloaded to the cable modem whenever it connects after being reset. You,
the end user, do not get to configure any component on the cable company's
network, including the cable modem that you may have bought to place on that
network.

The ISP controls the modem. Add a router between the modem and
the PC and do your config there. Netgear/Linksys routers are
cheap (at least here in the US - $30-40 on sale after rebate)
and they give you added security to protect your PC. Get a
wireless G router if you need wireless - else just get a wired
one for maybe $10 less. Either should have a 4-port switch to
connect your wired computers.
