Wireless users getting EAP time-out Error

[Rahul Wankhade]

Please refer below logs which I captured in RA trace. 

2026/07/03 05:06:56.166 client-orch-sm Controller initiated client deletion with code: CO_CLIENT_DELETE_REASON_CLIENT_EAP_TIMEOUT_FAILURE. Explanation: Client reported EAP error on deauth frame. Actions: Check AAA server, and collect RA trace and over the air capture

2026/07/03 05:06:56.193 client-orch-sm Controller initiated client deletion with code: CO_CLIENT_DELETE_REASON_FT_AUTH_RESPONSE. Explanation: Client failed pre-authentication during FT roaming. Actions: None required, if this happens frequently, collect RA and AP side debugs for the client

What could be the issue ? on ISE end no disconnection, looks good. FT also disabled on WLC. Please help here to fix this issue.

Its already set to optional.

So, as previously suggested, try updating the network card driver.
