Comcast modem trouble? Vey 07-27-07

Surfboard died.
Swapped it and they gave me a new RCA Thomson. Ran the registration for
existing customers and i stopped at the last page. Different errors each
time I tried. After sitting on the phone for an hour, Comcast says they
could see modem, could ping it, I could ping yahoo, but could clear
registration mode.

They told me to swap it again. Got another RCA Thomson and exactly the
same problem happened.

So far, I haven't called again. Haven't had a spare hour at one time.
Anyone have any ideas?

If it's a DCM315, it can't transfer data faster than about 5M, no matter
what the cap is.

Don't try using the on-line registration. I've found it too buggy and
picky. Call and make certain they have the correct HFC MAC address in
their database.

It's the 425.

How do you stop it from starting the registration process? When I tried
to bypass it, it kept coming back to the same registration page and
wouldn't let me use the web, although I could ping, trace and I'll bet
use ftp. That has been true for the surfboard or the thomson modems on
Comcast systems. Must be some trick I am missing.

Change dns ip address.

Once the modem gets registered, you can power
down modem and computer, wait a minute by your watch, powerup modem.
That should get a good reset on the modem.
Next dhcp lease sent to your system should have valid comcast dns ips.

To *any* legimate IP address of a DNS Server? I know of several public
DNS Servers. Would one of those do? Or do I need to use a Comcast server?
