Zoom freezing for 5 seconds

[niicechris]

I co host meetings with a business account every other week. Meeting holds 80-150 people. I am the only device hard wired to our modem/router through COX internet (2000 up and down with 11-14 ping). During the meeting, our frame will freeze audio and video for 5 seconds, then says "internet is unstable" Everything is updated through my computer and zoom. I've restarted modem and did a power cycle on it as well. Is there something I'm missing? I assume it could just be the modem/router through COX internet and I possibly need to get a new one, but this shouldn't happen even with a cheap one as it's never happened before. Only at this location. Normally when internet starts to go bad the frame might skip and sound bad, but we only freeze for 5 seconds. There are times it happens once a day up to 6 times. Would really appreciate the help.
