Teams video crashes the internet connection when connected via ethernet cable

Copper Contributor

I have a strange issue which I can not resolve.

 

When making video calls through my wireless internet connection everything is fine however when I make a video call through the ethernet connection it crashes every time without fail.  I have tried 4 different ethernet cables priced from £10 to £50 so its definitely not the cable and I just got my Sky router changed as I hoped that was the culprit however the same issue has arisen.

 

I need to use the ethernet connection as its a better connection to work remotely off the office VPN.

 

It is clearly a Teams issue as all other video calling software works fine, its just Teams that doesn't.

 

Any suggestions apart from stop using Teams?

That is an odd one. You'd expect it to be the other way around.  First thing I would say is ensure Windows Updates are all up to date and applied?

Yes its very strange, I have been living with it for about 6 months its never worked, everything is fully up to date@PeterRising 

@GToner  Do you have any other device that you can try with the ethernet connection to check if the same thing happens?

I have now resolved this issue. the problem was that my ethernet cable was connected into a USB C adapter which housed other connections such as a second monitor, keyboard etc, and Teams for some reason crashed when using video through this connection. I now have a single ethernet adapter that connects into my USB A drive into my surface laptop and no longer have any issues. works like a dream!
I tried this method and it solved it for me as well!

This is absolutly annoying, i have the same problem but don't have the option to use an etheret via USB A.
Can someone give a posible solution to this issue or more information about it o directly how to solve it?
Thanks in advance.

@dannysateler I have the same problem with my laptop. It uses a combined USB-C adapter. My broadband is from Sky.

Using the combined USB-C adapter in my laptop, Teams will crash the newer Sky SR203 router BUT work perfectly with the older SR102 router.

It seems to be a combined router & adapter problem for some reason. The combination of both causes the problem.

I have the exact same problem. Does this have a fix?
