Clients don't join to C9800 with Flexconnect config

dijix1990 — Thu, 09 Mar 2023 12:34:13 GMT

WLC version is 17.6.4

I configured Flexconnect through https://www.cisco.com/c/en/us/support/docs/wireless/catalyst-9800-series-wireless-controllers/213945-understand-flexconnect-on-9800-wireless.html#toc-hId--458088354

but, I cannot join to AP

client tries to join sometimes and can't

- Review the C9800 configuration with the CLI command : show tech wireless , have the output analyzed by https://cway.cisco.com/tools/WirelessAnalyzer/ , please note do not use classical show tech-support (short version) , use the command denoted in green for Wireless Analyzer. Checkout all advisories!
Also use client debugging per : https://logadvisor.cisco.com/logadvisor/wireless/9800/9800ClientConnectivity , you can have client debugs analyzed with : https://cway.cisco.com/wireless-debug-analyzer

Ok, but the configuration architecture on the 9800 is completely different, strongly advise to execute the mentioned procedure for WirelessAnalyzer ,
