There is a very long thread on this forum regarding ths issue.   https://community.meraki.com/t5/Wireless-LAN/Wi-Fi-Clients-being-Disassociated-due-to-quot-excess-frame-loss/m-p/196892#M26701       We experienced this issue in our head office where clients were being roamed between AP's and loosing connection, looks like Meraki have finally acknowledged the issue.   We disabled client balancing on all the AP and this issue was resolved.   Another factor is wireless drivers can also cause this issue. Intel released some new drivers to resolve this issue   The latest Intel drivers for the AX201 wireless chipset has the following fix   When connected to certain wireless APs in 802.11ac or 802.11ax mode, network connectivity loss (Windows System Event ID 5002) might occur after roaming   https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-i... ...

This is the API I call to get client count per AP   https://api.meraki.com/api/v1/networks/<NetworkID>/wireless/clientCountHistory?timespan=600&resolution=600&band=<band>&deviceSerial=<APSerialNumber>   I pass the network ID, the band either 2.4 or 5 Ghz abd serial number of the AP, the time span I use is 10 minutes and this API is called every 10 minutes.   Once the results are returned back as a json file, I then do the processing to extract the details and write to a back end SQL database. I then have a Power BI report that can graph the AP client count over a period of time.   I did a very quick and dirty way to get this information am sure there is a better way but dont have time to look into this. For my purpose, the above works for me and been running past 12 months   More info here   https://developer.cisco.com/meraki/api-latest/#!get-network-wireless-client-count-history     ... View more

I followed the above documentation and it did not work   The AP is on a sinlge management VLAN 1   The AP's were tagged with the corresponding VLAN they are on (VLAN 4 and 5)   The switch port (MS switches) were the AP are connected to set up correctly as per the document   However the VLAN tagging did not work for me, the incorrect VLAN tag was applied to the packet   DHCP is served by the MS switches   As an example I am on VLAN 5 so get IP from VLAN 5 when I move to VLAN 4, my IP is still on VLAN 5 and doing a packet capture on the switch where the AP is connected to, the DHCP request is tagged with VLAN 5 and not VLAN 4. ...
