does SB6141 not work with cox?

We had the Panoramic modem/router on the gigabit plan.  Then we downgraded to preferred (150mbps).  Since there was no need for the Panoramic modem, I tried to activate a SB6141 with Cox over the phone.

During the bootup sequence, the SB6141 send/receive lights turned solid green, but the internet (globe icon) light just kept flashing, before the whole cycle repeated.

I tried several things with the technician:

* Unplugged the modem, waited for a few minutes before plugging it back in

* Tried the coax in a different room

* Tried connecting my laptop directly to the modem instead of via the router

* Verified the serial number and MAC address

* Verified the work order for downgrading to preferred internet was completed

The technician said that they couldn't even send a reboot signal to the SB6141 because it was offline.

His theory is that DOCSIS 3.0 isn't supported in my area, even though DOCSIS 3.1 is.  I don't know how much sense that makes.  He believes that if I just buy a DOCSIS 3.1 modem then everything will just work, but I'm doubtful.

What are we missing here?  Is this a known issue?

    Does it need to be reset to factory defaults, maybe?

    The 6141 is listed on their list of approved modems.  I had to rollback my modem to a D3.0 and its worked perfectly for 2 years.  You can try resetting your modem from your Cox account.  I guess first is to ensure your 6141 is even appearing on your Cox account.

    If you can email your full name and the street address on your Cox account, I’ll be happy to investigate.
