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.
I've been having the same problem and it is most apparent in Teams.
I did roll back my AC1900 Wireless Dual Band Gigabit Router firmware to 100.2 - there was an update in July that was really unstable and dropping 5ghz connections.
That stabilized it until 9/28/2020 and for the past 5 days I've been back to a similar, but not as frequent, issue. I hadn't connected it directly to teams and suspect something is interfering with the wifi signal.
let me know if you find a solution.
as I was typing this I found the "Mobile Hotspot" settings in windows and even though it is "off" I changed it from "Share via wifi" to "Share via Bluetooth" as a precaution.
ericsnell I ended up switching from a 2016 Dell XPS 13 which severely had the problem, to a 2015 Dell XPS 15 (hey, it was laying around) and I didn't have the problem. The XPS 15 had to go back, so I bought a Dell XPS 17 last week. So far just the typical wifi issues. My Killer wifi app is saying my access point is old and I should replace it. I bought it in 2019, so yeah.
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.
ericsnellThis fixed my issue - thanks!
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 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).
