I doubt you have a modem failure.
I've never had a modem fail, and very few do - rather they are
usually replaced because 1) someone missed a level issue
somewhere, 2) they were blew out with lightning, or 3) you
wanted a docsis 3.x modem for better speed.
I take that back - buy either a cisco/scientific atlanta modem, or a
motorola, always. Moto made the first docsis modems, and still
generally make the best, otherwise cisco (!linksys). If not, it's a
firmware incompat between the cmts and it, it has happened.
I don't know how much they allow crap to enter that market these
days, but you used to find the "Best Quality" Fry's special modems
in the docsis1.1-2.0 days that would literally degrade over time
like an hourglass running out of sand, but electronically. Crap
components, capacitors, ic's and such break down electronically,
incomplete hand-solders from workforce sweatships, radio's
modulating data on rf freak out doing weird things the cmts doesn't
like to enact mitigation techniques.
Caveat emptor, just buy a moto/cisco and be happy, cox uses cisco
cmts's upstream to terminate your connections. They began
blacklisting "bad modems" specifically at one point, I think
CableLabs made them clean up to certify (vs. world+dog), maybe...
