                                     - As far as the wireless part is concerned :
   Have a checkup of the WLC 9800-L configuration with the CLI command show tech wireless and feed the output to : Wireless Config Analyzer

    - Also look into : https://logadvisor.cisco.com/logadvisor/wireless/9800/9800CWA

   - Further engage in full client debugging according to https://logadvisor.cisco.com/logadvisor/wireless/9800/9800ClientConnectivity , these debugs can be analyzed with Wireless Debug Analyzer

  - Outputs from the commands mentioned in https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/217738-monitor-catalyst-9800-kpis-key-performa.html#anc5 can also be useful

   - Check software version on the WLC 9800-L ; go for latest advisory = 17.12.3

Thank you for your suggestions and guidance.

Unfortunately, the steps you provided did not resolve the issue. We have also tested with a WLC 5520, and the problem persists.

 

  - Then try to do the full client debugging on the 5520 too ; feed that into Wireless Debug Analyzer (too)
     Compare the session with the full debug on the 9800
                       For the 5520 go 8.10.196.0 (if needed) and try again

We suspect that the issue might be related to the process of the captive portal on Apple devices. Do you have any  recommendations to address this specific problem?

 

  - Since the problem remains the same on both controller platforms (9800 ios-xe and 5520 with aireos) , it seems a 'local apple' problem indeed  ; you could for instance post the problem in :
