Capwap Tunnel Across WAN to Central Controller

We are having an issue with a remote location that connects to to our HQ via an MPLS network.  They have 17 lwapp access points that connect back to a central controller.  The issue is when bandiwdth utilization gets high or at capacity, the wireless clients are getting dropped from the WLAN.  I assume this is because latency is getting so high that the capwap tunnel is going down between the AP's and the Controller.  The issue only happens when bandwidth is fully utilized.

These wireless devices are accessing resources at the HQ.  All of their traffic comes across the WAN, and not locally within this facility.  Would configuring these for FlexConnect help in this siutation?  Should be consider adding a local controller at this location to prevent the wireless users from getting disconnected from the WLAN?  Thanks.

You should first try to use FlexConnect and drop all the traffic locally at the remote site. This should help, because if it doesn't, then you need to increase your bandwidth.

You could also try to QoS the capwap data over your wan

We are going to try FlexConnect first.  Thanks.

Yeah that what you should do.. Depending on the bandwidth also, if you have high latency, on a FlexConnect ap there is a setting for high latency.

I was not aware of the high latency setting.  Can you please on where that configuration setting is?  Thanks.
