Intel WiFi6 AX201 160Mhz L3 Issues with RADIUS Authentication

We have several Dell Latitude 3520's, more are coming, with an Intel AX201 wireless adapter in them, that are experiencing connectivity issues. These issues take place whether the connection is an 802.11ac or 802.11ax based. The problem occurs when our uses authenticate using 802.1x to gain access to our network. When first connecting our users will authenticate successfully and have access to the network but, when the reauthenticate interval expires L3 connectivity gets dropped. The user will authenticate successfully but L3 connectivity stops. To clear this up we have to either disconnect/reconnect to the WiFi or wait for the next reauthentication interval to expire and L3 connectivity will return.

We are an Aruba shop and at locations where this issue currently exists we are running Aruba IAP-305s and IAP-535s. We have worked with Aruba to rule out an issue with their WAPs via packet captures and debugs. When the issue occurs we can see the Aruba WAPs sending the icmp packets back to the laptop but the laptop does not see them.

 

What we tried so far without any change:

What has worked so far:

  • When we use a PSK for the SSID there are no issues.

Laptop(s) details:

Dell Latitude 3520

NIC - AX201

WIN10 - 20H2 - build 19042.1288

 

I've attached an Intel scan to this posting.

@Josue can I receive also a copy of this driver?

Additionally, how can I enter in the beta tester group for new wireless drivers?

 

Kind regards.

I'm testing the new 22.110 driver moderators shared with me in some laptops, and the issue still happening on a Cisco WLAN infrastructure. When the user is roaming from one AP to another, connection is lost (L3 but not L1-L2) and the user needs to manually reconnect or wait for a new re-auth period.

 

Regards.

Are you sure that you are using the new drivers? I had to revert to older drivers before I could install the new 22.110.0.2 drivers.

 

We are using Cisco as well and so far so good.

@JPavonM , how did you get the 22.110 version? We experience the same problem and would like to try this same version. Are you able to send it to me or ask your Intel contact to do it for me? Thanks for your response.

Hello All,

 

Just to clarify some of your questions, the current driver that includes the fix should be version 22.110.X. This version should be avialable through your OEMs. The generic version of the driver that Intel posts will be avialable via donwloadcenter.intel.com next week.

 

I would recommend you to check first with your OEM and also install the OEM version of the driver. Our generic drivers also will include the fix.

Most of the customers have reported the issue has been fixed by testing with this version of the driver so for those that have been experiencing a different issue I would recommend to create a new support ticket so this could be evaluated. 

 

Thank you all that have confirmed the fix using the driver provided .

 

thank you

David O.

Also experiencing this issue on Dell Latitude 5420 with Intel Wi-fi 6 Ax201. Seems to have started happening in the last week or so. Latest driver on Dell site is 22.100.3 so now we are trying the driver on Intel's site 22.100.1 to see if issue has been resolved: https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-intel-wireless-adapters.html


Can you please send me the driver that solves this if that one is not the answer? @DavidO_Intel ?

Good day sir

What is the date on the driver  that fixes the issue?

I don't see drivers posted at the OEM Dell site for PCs i.e Precision 3541 and 3551. 

 

Thanks in advance.

Hello All,

The new generic version of driver 22.110.1.1 for the WiFi6 and WiFi 6E Wireless adapters is now fully available here:

 

https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-intel-wireless-adapters.html

 

This version includes the fix for the original issue reported on this community.

@DavidO_Intel I'm still suffering the L3 roaming issue in some laptops with AX201 wNIC when using 802.1X-PEAP.

The laptops receive APIPA Address when roaming from one Cisco AP to another.

I've tested with generic drivers from Intel and with Lenovo drivers, using versions 22.40, 22.100 and 22.110 (both RC and final releases) and the issue is still there. Now testing with generic 22.30 to see if it happens.

Attached SSU results.

I also have this problem with my Surface laptop 3 and hp probook. Both have the AX201 chip with latest intel driver provided by Microsoft (22.110.1.1).

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.

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!

 Hello @Jaap_Heijmenberg 

thank you for sharing this level of details. As this seems to be a different issue I would recommend to open a ticket with our support team for additional troubleshooting.

Please attach the System Event and WLAN-AutoConfig logs.  Also if you could please provide an Over The Air trace would be great.
