Poor performance on Teams with Extreme Wireless

[VishalS]

Hi,

We have 2 x Extreme C35 controllers with an assortment of AP3805i,AP3912i,AP3915i installed. Our switches are GB. We are experiencing an issue of poor calls for our TEAMS video and audio calls. If we switch to cable then it works fine. The Teams dashboard reports that there is high packet loss and also very high round trip time to their servers. The user experience is laggy/choppy video calls. If they only use audio then sometimes it has a audio break. This doesnt happen for everyone in the building but only certain areas. We check signal to the AP's and its fine. What can i do to pin point the issue? I was thinking that its more of an issue with the backplane as signal is fine but performance is poor. Drivers and general software is fine with the end users. Thanks

Hi Johannes. Where do i find this setting? Is it the MTU setting? Currently on 1500. What is Eth? thanks

Are you using bridged@controller? In that case, the AP uses a tunnel to the controller and if the controller is on another site and you are using e.g. ipsec vpn tunnel between AP and controller, there is another tunnel (MTU reduction, IP fragmentation and so on).

Maybe you can switch to bridged@AP and break out locally (vlan tagged at the AP). We are using that scenario and we do not have problems with MS Teams.

However, we had some issues with certain devices (e.g. old Surface with Marvell chips), but in all these cases a driver update on the device helped.
