Consistently drop MS Teams meetings from laptop or smartphone

Within the last two months, beginning late December 2023, when I participate in MS Teams meetings using my Xfinity home internet/wifi my Teams sessions will eventually freeze and drop. This happens on two different laptops and my smartphone. I've had to resort to rejoining those meeting on my smartphone with going through my Xfinity wifi. In those cases, my Teams sessions continue without problem. I've had virtual meetings with other apps and have never had a problem. Only with MS Teams.

During these moments I am the only one home. There is no bandwidth issue with household items taxing the wifi. No streaming, no gaming, no video watching. Just me trying to use Teams.

I've run the speed test which always gives me above my 800 speed on my plan. But that does not seem accurate as in these same moments I cannot load simple websites. But this is a different issue; not for this posting.

I've cleared cache, restarted laptops/Xfinity modem, unplugged Xfinity modem for long periods of times, etc,...

I've looked at these forums and other sources online with no solution.

Looking to the brain power here to tell me what I'm missing.

Appreciate the collective experience, and frustration, from this group!
