Hello
i have recently purchased new ap model 9105AXI to replace some AP 1815i , so i have updated the VWLC to the version 8.10.196.0
since this upgrade i have noticed that client are disconnecting randomly when connecting to both model 9105axi or 1815 . im trying to figure out the root cause of this behavior

 - Have a checkup of the WLC's configuration using : WirelessAnalyzer input (procedure) for AireOs controllers
                                                     and feed the output from that into Wireless Config Analyzer

thanks a lot for the feedback , based on the analayser i dont have errors related to RF parameters . im wondering if a mixed wireless envirement with 1815i 802.11ac with 9105ax 802.ax capability could cause issue , as issues started after upgrading the vwlc version  , and intlalling 9105ax ap . i think that i have to custom channels configuration , to make config adequat for both models .

 - It would indeed be better , to have a deployment with all the same AP models ;  you can also
   debug clients (disconnecting or not) ; using 
            WLC # debug client <MAC ADDRESS>

  Client debugs can be analyzed with : Wireless Debug Analyzer
  You can stop that or all debugging on the controller using : debug disable-all

regulatory domain.

Thanks a lot for the idea of the Analyser

I have question please is there a way how make policy to change all access point from local to flex connect mode even for access point that i will add in the future.

By assigning a properly configured site tag, APs can be automatically converted to FlexConnect mode.

Auto-Convert APs to FlexConnect Mode
When you assign a site tag that includes a Flex profile, the AP will automatically convert to FlexConnect mode without any user intervention.

So, every new AP which joins the controller have to get this site tag (Statically/Regex).

In older AirOS controllers (e.g., 8510, 5520, and 8540), this could be done using the CLI command:
(Cisco Controller) >config ap autoconvert
