AX201 can't auth RADIUS on WiFi6, WiFi5 works without problem

[Jaap_Heijmenberg]

Hi all,

I have a strange problem with my Surface laptop 3 and HP Probook. Both have the AX201 chip with latest intel driver provided by Microsoft/Intel (22.110.1.1)

Whenever I try to connect to my AP with WiFi6 ( Ubiquiti W6 pro) I can't authenticate with RADIUS. The network is detected but does not ask me for credentials but rather say 'can't connect to this network'. When I use the same AP without RADIUS all works fine. When I use the laptop with an WiFi5 AP (Ubiquiti AC AP PRO) I can connect to the RADIUS authenticated network. Both AP's use the same RADIUS server and settings and also share the same physical network.

I found out that if I set '802.1n/ac/ax wireless mode'  to '3. 802.11ac' in the driver properties. Then I can connect to radius Wi-Fi.

Without this setting-change I cant connect or even get a request to supply credentials on my laptops. My iPhone 13 Pro works fine btw on both AP's with RADIUS.

I use a Ubiquiti wifi6 pro access point with the latest firmware. Also I use a Windows server2022 with radius.

Please release a fix for this problem!

Thanks in advance!

Not that I know. I started using my WiFi6 AP and then the problems started.

- Was the wireless adapter pre-installed or was it installed in your systems?

The wireless adapters are pre-installed. A Surface laptop cant change it's network interface. Also my probook adapter is pre-installed.

I already installed the latest drivers with a clean installation. Nothing happened.

Thanks for the support already!

I also have the latest driver from Microsoft 22.110.1.1

Hello Jaap_Heijmenberg,

I apologize for the delay. We are still working on this issue, and in order to continue with the investigation, we need you to provide traces from the AP side. For this, you need to get in contact with the AP manufacturer (Cisco or any other in your infrastucture) to get the traces.

Here is a example of files type and extension:

I look forward to hearing from you.

Hi Steven,

I asked Ubiquiti how to get the logs you want. I let you know when I receive the logs!

Have a good day!

Kind regards,

Thank you for you response.

Please let us know once you have the logs in order to continue with the investigation.

Hi Steven,

Ubiquiti replied to me and suggested to turn of PMF an thus WPA3. They also told me to turn off BBS transition. 

After I did that my laptop connected immediately with RADIUS on WiFi6. If you want I can revert the changes and collect logging for your investigation. Maybe you can build a fix for the problem then.

Let me know!

Kind regards,

Jaap Heijmenberg

[Steven_Intel]

Thank you for your response.

I'm glad to know you were able to connect after those steps were performed. I will check the information you have provided and then let you know if we need the logs.

Please feel free to reply if you have any concerns.

Hello Jaap_Heijmenberg,

Based on the fact that the issue was fixed from Ubiquiti side, there is no need to get the logs. In case the issue reoccurs, we recommend contacting Ubiquiti as a first option.

If you need any additional information, please submit a new question, as this thread will no longer be monitored.
