Hi there,
Currently we are facing an issue where some client wifi adapter disappear when connected to our new Access Point.
Our new Access Point is Cisco C9120AXI-F with 9800-L WLC (16.12.4a), and our client WiFi driver as below:
Client wifi adapter works properly if connected to AIR-AP2802E-F-K9 with the same WLC.
Is there anyone facing the same issue and already solved?
Thank you in advance.
