WPA2-Enterprise unable to connect in Windows 10 version 2004?

I am unable to connect to WPA2-Enterprise (or WPA3-Enterprise) using TLS networks (any and multiple) after upgrading from Windows 10 version 1909 to 2004 (OS Build 19041.329). At present, I am using an Intel Wireless-AC 9260 with driver version 21.90.3.2.

I've spent a few hours trying all combinations of the following, without success:

  1. Downgrading to driver version 21.80.2.
  2. Changing the wireless card to a 8265NGW.
  3. Performing a clean re-install of Windows 10 version 2004, both before and after all Windows Updates are applied.


The following, however, allow for successful connections:

  1. Performing a clean re-install of Windows 10 version 1909. This works with both the 8265NGW and the 9260, using either the 21.80.2 or 21.90.3.2 driver version, both before and after all Windows Updates are applied.  However, then upgrading that Windows installation to Windows 10 version 2004 breaks any WPA2-Enterprise connections, only allowing for PSK.
  2. Using a cheap Realtek RTL8188CU Wireless LAN 802.11n USB 2.0 adapter works (albeit without the AC speeds, or 5 GHz).


This seems to clearly show an issue with WPA2-Enterprise within the Intel drivers under Windows 10 version 2004. Can anyone else confirm working or non-working scenarios here under Windows 10 version 2004?

What I do see are many repeats of the following sequence of Event Logs under WLAN-AutoConfig:

  1. Event 11010

    Wireless security started.

    Profile Name: ********
    SSID: ********
    BSS Type: Infrastructure
    Failure Reason:The operation was cancelled.
    RSSI: -35

So why is the connection immediately stopping after receiving an authentication succeeded? I.E., why was the operation cancelled?

I've also reviewed the logs on the WAP, including packet captures of the RADIUS traffic.  There are no errors included, other than EAP successes, and even a momentary STA association and connection.  It's almost as if in Windows 10 version 2004, this "success" message is never making it from the driver to Windows.

Please advise.

Re:WPA2-Enterprise unable to connect in Windows 10...

Hello ziesemer


Thank you for posting on the Intel® communities.

In order to check this further, could you please provide the following information?


1. Are you having issues with Wi-Fi only or with Bluetooth too (both)?

2. Is the Intel® Wireless-AC 9260 the original wireless adapter that came pre-installed in your system or did you install it on it?

3. Have you checked if this issue happens on different networks? Could you please provide an example of other networks or non-TLS network when it is working fine for reference purposes?

4. Router/Access point brand, model, and firmware version:

5. Have you tried a different router or Access point for testing purposes?

6. Computer power source: plugged in or battery?

7. Network SSID stealth mode: hidden or broadcast?

8. How many systems do you have affected by this behavior?

9. Wireless security method:

  • Encryption Type (Open, RC4, TKIP, AES):
  • 802.1X authentication type (WEP, TKIP, CCMP): 
  • Key Management Type (PEAP, EAP-FAST)


10. If possible, have you checked if this issue happens testing only the PC/laptop and the router/Access Point? (no other wireless devices connected to the wireless network during this test).



Also, please run the Intel® System Support Utility (Intel® SSU) and attach the report to this thread to gather more details about your system.

 

1- Download the Intel® SSU and save the application on your computer.

https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-

 

2- 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".

 

3- To save your scan, click Next and click Save.



Best regards,

Re:WPA2-Enterprise unable to connect in Windows 10...

Hello ziesemer


We just noticed that you have contacted Intel® Customer Support directly and we found out that you are being assisted through an internal support case regarding this same issue. Having said that, we will proceed to close this thread to avoid duplication of effort and the assistance will continue through the internal case.


Best regards,

Re: Re:WPA2-Enterprise unable to connect in Windows 10...

Thank you for the prompt reply!

Issue is with WiFi only.

I separately and recently purchased the 9260 as an upgrade to my system's original 8265NGW, in order to benefit from the latest Intel driver versions and WPA3 support.  Both, however, are now having the same identical issues with WPA2/3-Enterprise connections - but only under Windows 10 version 2004 (upgrade or reinstall).

I have no issues connecting to any WPA2-PSK or even WPA3-PSK networks.  I did also try creating a new test WPA2-Enterprise network on 2.4 GHz instead of the prior 5 GHz for testing, with the same results.

For testing purposes, I have a NETGEAR R700 or a GL.iNet GL-AR750S, both running OpenWrt 19.07.3.  I also have a few TRENDnet wireless routers that I could install OpenWrt or stock firmware on.

Otherwise, for different access points - I am looking for additional options available for testing.

Computer power source: Plugged-in or battery, does not make a difference.

Network SSID stealth mode: Broadcast.

How many systems do you have affected by this behavior?  One at present, but already ruled-out a faulty Windows installation by performing a clean re-install of Windows, and multiple wireless cards.

Wireless Security method: AES, CCMP, EAP-TLS - as detailed at https://www.intel.com/content/www/us/en/support/articles/000006999/network-and-i-o/wireless-networki... .

When I created the WPA-2 Enterprise test on 2.4 GHz, it was a single-device test.  I will re-test on a completely isolated WAP and SSID.

I will run the Intel SSU.  Is there a way I can PM the results to you, or otherwise upload to Intel - without attaching to the thread?

FYI, Intel case # 04714529 has since been opened for this issue as well.
