MS Teams Dropouts on roaming

[r0ssc0]

We have 802.11r enabled for fast roaming, but we are still getting MS Teams Dropouts when roaming occurs.

As we have Client balancing enabled, this is causing a lot of roaming to balance load(active load balancing).

We are planning to turn off Client balancing off to prevent this occurring(passive load balancing).

Question is will the AP's require a reboot to apply the new radio profile settings

[r0ssc0]

I am thinking no, but just want to check before making this change in the middle of the day.

Changing radio settings doesn't require a reboot of the AP.

I don't believe changing client balancing impacts connected users but I've never tested.

I'd suggest making the change out of business hours just in case.

What AP are you using ?

What firmware version are you running ?

What kind of SSID ? WPA2-Enterprise ?

What devices are you using ?

What Wireless NIC cards ?

Any relevant info in the roaming client page ( https://documentation.meraki.com/MR/Client_Roaming_Analytics#:~:text=With%20the%20introduction%20of%.... )

Wouldn't be surprised that you are hitting a know issue with Microsoft/Intel with 802.11r. 

Do you have any logs in Wireless Health that indicates an issue with the roaming ?

[r0ssc0]

The only indication we have is that there is a roam event in the logs and teams meeting takes a hit at that time.  I have turned off client balancing and it seems to have stabilised some what, although one still had a roaming issue with a  surface today, so I have changed the roaming aggressiveness down to low/medium on that device.
