Slow Wireless Authentication to Wireless Network

[compughter]

Good day. We have updated wireless NIC drivers to fix and issue where clients could not authenticate at all to the wireless network .   But now we are having an issue where clients take a long time to authenticated wit 802.1X and  EAP-TLS  to network with less and 100ms latency between RADIUS server and client.  The clients wireless NIC are all Intel. Client will not respond to the WLC/AP that is sending the EAP-START.WLC/AP is sending EAP-Identity-Request to the client.

Clients will  go into a loop of authenticating but eventually three to four minutes in will connect. It is a common occurence and extremely hard to troubleshoot. Debugs show the traffic and it stops at the WLC/AP ..this is a Cisco implementation. 

Feb 09 09:25:00.891	*apfMsConnTask_7	Client made new Association to AP/BSSID BSSID
Feb 09 09:25:00.891	*apfMsConnTask_7	The WLC/AP has found from client association request Information Element that claims PMKID Caching support
Feb 09 09:25:00.891	*apfMsConnTask_7	The Reassociation Request from the client comes with 0 PMKID
Feb 09 09:25:00.892	*apfMsConnTask_7	Client is entering the 802.1x or PSK Authentication state
Feb 09 09:25:00.892	*apfMsConnTask_7	WLC/AP is sending an Association Response to the client with status code 0 = Successful association
Feb 09 09:25:00.959	*Dot1x_NW_MsgTask_2	WLC/AP is sending EAP-Identity-Request to the client

Hello @compughter

Thank you for posting on the Intel® communities.

In order to review this further, could you please provide us with the following information?

1- Just to make sure we understand correctly, is the issue only "slow authentication without failing the connection"?

Or when you say "slow authentication" and "Clients will go into a loop" do you mean the authentication fails a couple of tries until it successfully authenticates?

2- Is this occurring with a particular Intel® Wireless card model or with different models? Also, could you please confirm the driver version(s) affected by this behavior?

3- How many systems (clients) are affected by this behavior? Is this occurring on different computer models or with specific models? Please provide details and maker and models of the computers:

4- Are the wireless cards the original ones that came pre-install on the systems? Or did you integrate/replace them on the computers?

5- Run the Intel® System Support Utility (Intel® SSU) to gather more details about the systems:

• Download the Intel® SSU and save the application on your computer
• Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".
• To save your scan, click Next and click Save.
• Once you have saved the file (.txt file), please attach it to your reply.

To upload and attach a file, use the "Drag and drop here or browse files to attach" option below the response textbox.

Yes please :  you can close it out. We are trying other things ie updating the Cisco Anyconnect supplicant - as well as Intel drivers .
