Finally got on site and confirmed no Internet access via Spectrum Cable. Called it in and waited…
Since they were projecting an end of day service call, I purchased another modem just in case it was simply toasted and the cause of the issue. No Joy, same no signal as before.
Cable techs arrived and after some amount of coaxing I convinced them to swap out the house coax feeds going to the modem ( see what I did there ? Coaxing coax… I crack myself up ) I think there was some water intrusion that killed the line into the house.
For kicks I put the old modem/ router combo back online but found that the hardwire speeds were significantly higher than the old router wifi. The old router would only pump 8Mb up and down, it was ridiculously slow, so installed the new modem/router combo and that made a huge difference.
TLDR: Bad coax, bad router.
