Microsoft Teams crashes my entire Internet connection after starting a meeting

Hi All,
I have experienced a very similar problem for weeks on end until I have finally solved it by setting up my WiFi networks a bit differently in my Bell Fibe 2000 access point.
Background: My main SSID (let’s call it “MyHomeNetwork” was set up to use any one of both WiFi bands indiscriminately (2.4GHz and 5.0GHz). The secondary SSID (“Guest”) works only at 2.4GHz. After a bit of research, I learned that the 2.4GHz band is the most used in general, by all kinds of connected devices, and that it can get pretty crowded and become susceptible to interference. I was able to verify that fact and I noticed that my neighbors are very connected, especially at 2.4GHz.
The main WiFi network on the 2000 access point can be set to use: 2.4GHz only, 5.0GHz only or both bands. In addition, if you set it to use both bands, you can choose to set a single SSID name or two different names. Even if you set two different SSIDs for the two bands on the main network, it will act transparently as single network, and devices that connect to different frequency bands will “see” each other. Password settings have no influence (same or different).
Experiment: I tried disabling the 2.4GHz band while keeping the same SSID and password. My next video sessions worked fine, with no dropouts. After a few hours, though, I noticed that my printers, thermostat and a few more devices were no longer able to connect, because they can only work at 2.4GHz.
Solution: I created and assigned a different SSID to each band of the main network. I called them “MyHomeNetwork_2.4GHz” and “MyHomeNetwork_5.0GHz”. I reconnected my devices to the most optimal band that each one was capable of (obviously 5.0GHz for my laptop) and everything has worked flawlessly ever since. At least 100 hours of Teams and Zoom without a hiccup.
I hope that helps some of you.
lglefebvre I'm glad it works for you!
Last time I tried it was still crashing on me about a couple of weeks ago (by mistake I didn't use ethernet as the wire was connected to a test machine). I mostly use a 5GHz AP here on my Mikrotik (I have 2 separate ones for 2.4 and 5) but 1 or 2 years ago when we started home office, I tried both frequencies and it didn't help me. Another place I was getting these Wifi disconnects was at my parents place using a Huawei T provided router (I believe that was 2.4 only).
So by all means people, try 5ghz only AP or what you can think of, but to some people this occurs and Teams client is still causing network disconnection, and heavy performance issues. Since this started, Teams is still the worst piece of software I use.
