Bad network quality

Occasional Visitor



Very often I get message during MS Teams conference calls "Bad Network quality" and then video starts lagging and voice quality drops. I am using a WiFi at home. When I connect to a WiFI 2.4GHz I get less bad network messages, then on WiFi 5GHz and if I connect to a mobile network via my cell phone's mobile hotspot it is even more stable.   It does not make sense to me because my home network on WiFi 2.4GHz provides 7ms ping and 40 Mbps download and on 5GHz WiFi it provides 3 ms ping and from 250 to 400Mbps.  However mobile network provides 33ms ping and around 20-40 Mbps download speed.

Is it really an issue with internet provider of my home network? I do not notice any problems using WiFi on other applications and devices.  For example ZOOM works without issues or Skype.

Are the calls just audio? Or is video and content being shared as well?  What kind of wireless equipment do you have at home?  Teams should automatically adjust quality of video, sharing, and audio based on the network bandwidth.  I have found similar situation myself, but I've also noticed when connected to 5 GHz wifi in my house, it fluctuates quite considerably on signal strength sometimes (even when I'm stationary).


On the call quality, can you take a look at the one of those calls on 5GHz and look under Network and see what the values are like for round-trip times, jiter, and packet loss, both from and to the service.  Compare those against being on 2.4GHz.

@Eriks_Lizbovskis It sounds as if you don't have the best local network connection. The varying WiFi speeds definitely seem to be an indicator. They should be the same if you are pinging. 


A ping represents a few bytes of data, it can tell you some things but not everything. Plus it sounds as f you are pinging a local router, so you have many miles to go before you get to the Teams servers. Also, ping and network download speeds have known to be cheated upon by some Internet providers. They can see what you are doing and temporarily provide significant amount of bandwidth to make the test look good.


Ping and Internet tests all represent small portions of time when compared to a video call. 


Try connecting directly with Ethernet. That will help determine if it is a WiFi issue.

A Bad Network quality can be very transient caused by many things, such as someone else on your network starting to stream data, or other people at your ISP. 


If you don't need to transmit video, then don't. You should also be able to turn it off from coming in. Video uses 20+ times the amount of network than voice does.
