Frequently dropping internet - SYNC Timing Synchronization failure, RCS Partial Service, No Ranging Response received | Internet Problems
For the past 2 weeks the internet in my household has been frequently cutting out.
Sometimes it will disconnect every hour or two, other times it will disconnect multiple times in the span of 30 minutes.
Even when I hardwire my ethernet cable to the modem the issues persist as usual.
The technician on the phone said that everything seems to be normal from their side, and the technician that came out to check out the problem also said that he didn't see any issues.
I have been using the service with minimal issues for about 6 months, but the past 2 weeks have been awful. Even though I disconnect 20+ times a day, the internet speeds seem to be normal (I have frequently run speedtests) while the internet is functioning.
Through troubleshooting, calls with technicians, and a visit with the technician, it is guaranteed that the problem is limited to:
1. Modem
2. Wiring
3. Cox
I went to 192.168.100.1 to get more information about the modem (Arris SB6190) and saw this:

I would really like some help as to how to fix the problem, I require a stable internet connection for work and I have resorted to using a hotspot from my phone just to have consistent internet!
