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:

  • Notebook Type: HP 440 G7
  • Driver Provider: Intel
  • Driver Date: 29/8/2022
  • Driver Version: 22.170.0.3

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.

Hi

 One thing I saw already was the connection to be Black listed due too many fail authentication attempt.

 But it would be a temprary situation. If in you scenario the Wi-Fi adapter actually disapear, id like to know more about it.

Upgrade Intel driver to latest - those drivers have been riddled with serious bugs:

Upgrade your WLC software as per TAC recommended versions below.
