Microsoft Teams crashes my entire Internet connection after starting a meeting
Hello Jared327 This is something you'll definitely want to report to our answers.microsoft.com tech support site.
Bear7609 Turned out not to be teams at all - it is either the NIC driver on my Laptop or the 5ghz band on the router - I turned off 5ghz band on the Nic on my laptop and everything is stable! - I have to narrow down if it is the router or the laptop. Going to take the router back to 1.0.9.42 per a recommended article and then turn 5ghz back on and see what happens.
ericsnell I have the exact same issue. My LTE router works fine for hours but whenever I setup a call on MS teams, internet connection suddenly stop. And one more amazing thing happens, when connection stop working I can hear my colleagues voice for a minute while they can't hear my voice and then call drop eventually.
noornawaz I don't think it was Teams - I think it was my router and software - I had an AC1900 router that was 4 years old (Netgear nighthawk 7000r) and the last two firmware updates seem to have made it really unstable. Something was broken with the 5ghz band (at least). I gave up and purchased an AC3000 Orbi router+satellite and it has been 100% stable (and more in-the-house-bandwidth).
noornawaz I am using a MacBook (BigSur) and the native Teams client for Mac and I have the same issue: the upstream stops... the router halts but I can hear (and see) my colleges talk for another 20-30 seconds or so. After that I have to hard reset my router to get online again.
I even re-installed my whole OS and made a factory reset of my router. The issue still exists.
One workaround though is to use the browser version of teams for web-conferencing with teams. This seems to work (using latest Chrome).
