WiFi6 AX201 160MHz Capability Reset and WiFi Disconnection Issues

We are having persistent disconnects on our Enterprise WiFi with many devices, all with Intel AX201 WiFi6 adapters. It seems to be a compatibility issue between the Meru APs and Intel adapters, but on our large network it is the AX201 adapters with the most prominent issue.

I have read quite a few support articles and attempted quite a few adjustments as per below.

When the disconnect happens, it always coincides with the following series of event logs. The wireless security triad repeats every 3-10 seconds, which seems excessive? Then the capability change, CapabilityReset occurs and the wireless drops from anywhere between a couple of seconds, and 5 minutes.

      11004 - Wireless Security Stopped / 11010 - Wireless Security Started. /11005 - Wireless Security Succeeded. (These three repeat quite frequently, every couple of seconds?)

       4042   - Capability change on {...} (0x47008000000000 Family: V4 Capability: None ChangeReason: CapabilityReset)

 

We have tried, old and new drivers (22.40, 22.80, 22.120, etc.), changing 802.11r/k settings on APs, changing channel bandwidth (Auto/20MHz) in Intel drivers, changing to 'Wireless mode' in Intel drivers,  adjusted channelling/power levels of APs, and quite a lot else. Computers are predominantly Windows 10/11, it has happened on all AX201 devices for as long as we have had them, PSK networks have no issue with the adapter or drop-outs.

 

According to this link , it may be a compatibility with APs. Can you please explain what the '4042 - CapabilityReset' relates to in the driver? Is there a fix/setting to confirm Intel AX201 compatibility?

Hello @kogies

Thank you for posting on the Intel® communities.


Just to make sure we are on the same page, we understand that the issue has been occurring since the first day that you have the devices and regardless of the driver version being used. Also, we understand that this works fine on "regular networks" (e.g.: PSK networks). Is this correct?

Could you please let us know if this issue happens using only the generic drivers from Intel® Download Center?

Or does this occur also using the customized drivers provided by the computer manufacturers (OEM)?


Due to the co-relation and functionality between the Wireless and Bluetooth components, it is always recommended to keep both drivers (for Bluetooth and Wireless) up to date and it is advised to use the OEM drivers as the first option (The driver or software for your Intel® component might have been changed or replaced by the OEM).

In case you haven't tried it yet, we suggest a clean install of the drivers using the latest system-specific driver from your computer manufacturer support following the steps on these links:


If the behavior persists, you may repeat the steps and perform the clean install (for both components: Wireless and Bluetooth) using the generic drivers from Intel:


If the problem persists, or if you already tried those steps, we will request you to provide us with additional details so we can review this further. For this purpose, we will send you an email to the email address associated with your profile.

Hi Andrew,

Yes, we have multiple devices on campus, from multiple manufacturers (MS, Lenovo, Dell) having the same disconnection issue. We first noticed issues with the Intel Wireless AC 8275 chipsets, and had slighter better results with an older driver (<2020), many other drivers post 2020 showed far more disconnects. In both cases these disconnects happened at occasional intervals (1-2 times a day per device). We have just been managing these issues, and replaced the Intel cards with Realtek ones to alleviate this issue.

However, we most notably on Intel Wireless AC AX201 chipsets, we have added a fleet of 90 devices this year with this chipset and are now getting more than 10 disconnections per day, about 2-5mins each. We have tried very many drivers to try and mitigate the issue. We are currently running 22.120.1.9 and have noticed no real difference, though also Windows Update was not capturing drivers newer than 22.20.0.6 on Surface devices through Windows Update.

Please see attached WLAN report of the issue (including event viewer logs, etc.). You can see repeated Wireless security events, not present on similar Marvell and Realtek devices on the same network.

Hello kogies

Thank you for your response and for all the details. Please allow us to review this further and we will be posting back in the thread as soon as more details are available or in case additional information from your environment is required.

Hi Andrew,

Just an update on this issue. We have done some further testing and found the APs were knocking the devices off the network. The Meru Virtual Cell (on older controller, so may be resolved/different on newer controllers) would force the devices to move APs and something was causing repeat security requests and causing the ~2mins of disconnection. We have disabled this and more common multi-channel network and haven't had any issues since.

It was still only on the Intel AC Wireless cards mentioned as far as we have tested, so there might be something worth investigating. Perhaps there is a driver/standards difference between Meru and Intel which is causing these disconnections. We don't have any disconnection issues with iOS devices, or some other, older AC wireless cards, and our Marvell AC cards work fine as well.

Hello kogies

We are checking this thread and we would like to know if you were able to review the emails we sent to you and if the driver 22.130.0 helped to improve this disconnection issue.

What was the solution for this?

Also interested if there was a solution for this.

 

For us, I have been able to narrow the problem to the combination of Wifi 6 AX201 and Meraki.

I reached this conclusion as the problem does not occur when people are connected to their home routers.
Also excluded the authentication as the source by testing the connection in a SSID with password and the problem still persists.

 

I'm stumped, I have logs from most of the computers that have this problem but no clear picture emerges.

I'm also seeing dame problem in a scenario with Meraki (both Wi-Fi 4 and Wi-Fi 6) in 5 GHz band. Our SSID is using RADIUS and accessing using active directory username and password. From time to time, laptops disconnects for around 25 seconds and reconnect. Netsh wlan report shows that disconnect reason is unknown. No way to tshoot this...

The details for the driver are this:

 

C:\windows\system32>netsh wlan show drivers

Nombre de interfaz: Wi-Fi

Controlador : Intel(R) Wi-Fi 6E AX211 160MHz
Proveedor : Intel Corporation
Proveedor : Intel
Fecha : 21/06/2022
Versión : 22.150.1.1
Archivo INF : oem280.inf
Tipo : Controlador Wi-Fi nativo
Tipos de radio admitidos : 802.11g 802.11a 802.11ac
Modo FIPS 140-2 compatible: Sí

 

And the incident has this procedure:desconexion-reconexion.png

 

If you perform a wlan report the reason obtained is unknown:

 

Interface:Intel(R) Wi-Fi 6E AX211 160MHz

Interface GUID: 6af95825-5073-4b00-b8b1-2e4888991ea1

Just wanted to document the solution that has worked for us 100%.

Solution

Download the latest firmware straight from Intel Windows® 10 and Windows 11* Wi-Fi Drivers for Intel® Wireless Adapters

Update both the Wifi and Bluetooth drivers to the same version. Difference in versions can cause problems.

Test before widespread deployment.

We installed the driver version 22.180.0.X that solved the problem.

Intel seems to be providing version 22.190.0.X. Test to be sure it works.

 

Speculation as to the source

The problem is the Intel drivers in version 22.150.X.X.

There seems to be some event in combination with Meraki and the Intel drivers that causes the connection to drop and not to be re-established right away. It seems to happen inside the drivers in a way that is not reported to the OS at all.

Manufacturers seem to lag behind in updating their Intel driver versions.

Hope this helps anyone struggling with this annoying problem.
