Intermittent Loss of Internet and error RDK-03033 on cable

I have been experiencing both of these issues for at least a week. Got worse today when the Internet went down 3 times while I was in a zoom meeting. Looks like the cable error has happened since May to many people. Have a tech coming tomorrow, but saw that the firmware fix that was suppose to happen in May did not address the issue. Working from home, so any ideas would be helpful as the frequency of the interruptions is increasing and do not have much faith in the tech knowing how to fix this one.
