Intermittent Connection Issues -- Just started this week Dec. 7th - modem data in this posting

I converted to work from home in March 2020.  My Cox service has been fabulous from then to just this week.  The only bandwidth being used in the daytime is for my work.  I am running the same equipment I have been running for the past couple of years.  Arris SB6183 and an ASUS router.  My Imac is connected to the 5Ghz wifi network and I've tried the 2Ghz network as well.  I cannot hardwire to the modem because the network card on my Imac has been fried for a couple of years.  

Starting on Monday this week (Dec 7th) I have been completely losing internet connectivity which requires a modem reboot to restore.  It seems like this is happening mostly when I am using my Imac to do a VOIP call using the RingCentral app.  I have not noticed any other loss of connectivity of issues outside of this.  As an example we stream HDTV most of the evening with no issues at all.

I checked my signal levels using 192.168.100.1 and signals/noise seem good but on the borderline in some cases.  My event log is quite extensive however.  I am pasting both in below.

    I've checked the surrounding area and not showing any issues that would be affecting service. The modem signal levels aren't at optimal performance levels. If you haven't tried unplugging the power cord, unscrewing all ends of the coax cable, and if there a splitter bypass it for testing purposes. If still experiencing an intermittent issue email your full name, address, and a link to this thread to cox.help@cox.com so we can schedule a technician out.

    It looks like there are more people with this issue, I am having the same issue with connectivity and called the technician to check tomorrow.
