Dropping connection during Webex and Zoom calls

We are getting internet unstable..  Audio drops while video stays up.. then full drop.. hardwired and wifi.   We've had a tech out that said signals in and out of the house are good.  Said something about a tap needing to be upgraded.  He was nice, but kinda just told me there was nothing he could do..  

I can't work anymore.. my kids can go to school...  I need this figured out.  I saw a post that it might be a bad modem.

Here's the log... lots of critical errors:
