Timing Synchronization failure S33 - Is there a firmware update?

My S33 modem was working great. Then 2 days ago I went to access printables.com to find something to 3d print. The site wouldn’t load. This was curious because I could stream netflix, apple tv, youtube, prime, and my son wasn’t experiencing any lag on Marvel Rivals. To add to the issue, I could access the site just fine from my cell phone connected to the same network. I finally punched in the ip adress to my modem and found in the event log a  Timing Synchronization failure with a date of 1970.

 

I checked with the ISP and the issue seems to be isolated to my house so I either have an issue with a coaxial connection or my modem has a problem.

 

This begs the question, is there a firmware update for the S33 that could resolve this? Is my S33 on the brink of failing? I believe the timing synchronization issue is what’s preventing me from accessing certain websites but I’m not certain.

Firmware updates are our least concern since all other services are functioning properly. When it comes to firmware, 

DOCSIS standards dictate that the service provider must distribute firmware updates to cable modem devices.  The end-user cannot simply install an update like most other network-enabled devices.
ARRIS develops the software update and makes it available to service providers.  The service providers qualify, test, and distribute the software update to devices on their network.  ARRIS has limited control or visibility on distribution by the service providers.

More importantly, we need to isolate the issue first. The S33 is just a cable modem, so you must be using a router. There is a possibility that the router might have denied access to the site. To confirm this, I suggest connecting a computer directly to the modem using an Ethernet cable and then checking if the site is accessible.

It was my router causing all of this. I did as you suggested and when plugged directly into the modem all functioned as it should have. I had a bad firmware flash on the router and somehow it was creating the behavior I reported.
