Microsoft Teams crashes my entire Internet connection after starting a meeting

I too have been experiencing this issue off and on for a couple months.

At first, I knew that something on my system was causing my WiFi to drop. It was dropping constantly, 3 to 8 times a day. So I used the Network Reset feature to see if that would help. Which it did not. Then I assumed it must have been something I installed, because the issue seemed to come out the blue - Teams and my WiFi had been working for months without any issues. So I went through and removed any software I had recently installed. This did not help.

I ran Windows Updates, Dell SupportAssist, Teams Updates, Office 365 updates, and Microsoft Store updates. Nothing changed. 

As a last ditch effort, I used Reset this PC to wipe my system clean, erased everything. I am backed up in OneDrive, so why not? This seemed to help for a couple weeks, but my old friend is back.

I can run Teams just fine using my iOS devices (the only other devices I have Teams installed on) and that gets me through the meetings I need to be in. But I can't really run a meeting myself without the WiFi dropping.

My husband is using a Dell Latitude for his Teams meetings here at home and he has had no issues.

Another thing that makes this hard to pin down, is that our ISP drops out about twice a week. I have to check my iPad to see if that has been dropped from the internet to be sure.
