anyone ever get an HWIC-CABLE-D-2 card to work?

I'm grasping at straws here, and reaching out to a
wider community to find out if there's anyone out
there that's been able to get an HWIC-CABLE-D-2
card to work. I figured it was worth giving one
more shot before I call and cancel my Comcast
account, as it seems silly to pay for a service I
can't use.

The card synchronizes with the CMTS system,
does all the happy dancing back and forth with
ranging, etc. and then just hangs waiting for the
TFTP transfer to complete. Tried different cables,
removing all splitters, plugging in right at the entry
point to the change. :frowning:

Here's the config on the interface:

Did you have comcast register this card on your account? When you try to
browse web do you get redirected like a modem in walled garden state?

Yes, I read the HFC MAC address off to the comcast
account activation people, and they repeated it back to
me to make sure it was correct.

I can't browse the web because the line protocol
state on the interface is still "down"--until the
line protocol comes up, there's no ability to
send or receive packets. :frowning:

If there were a way to force line protocol to come
up, and get an IP address on the interface, I might
then be able to get to the captive portal; but without
a usable IP address on the interface, there's no packet
flow happening at layer 3. :frowning:



Some cable providers do weird provisioning stuff with different flavors of
DOCSIS. Do you know if your HWIC supports the version of DOCSIS your
provider runs? It looks like those cards are good for DOCSIS 2.0, and many
new providers are 3.0 by now so that may be something to look into..?

Comcast does still seem to support DOCSIS 2.0 devices, I know
other people that are still using DOCSIS 2.0 devices without
issue, so I'm sure it's not just a protocol version number issue.
