Problem using 802.11r FT on Ubuntu (AX200)

Fink — Wed, 02 Dec 2020 16:17:32 GMT

Hi,

I'm trying to use 802.11r on my network, but I can't seem to make it work correctly.

I am connecting using wpa_supplicant using the configuration below, and while the connection is successful, it isn't registered as an 802.11r compatible device according to the network. I took a look at the association request packet, and i can see that under capabilities for "Mobility Domain" that the capabilities are set to 0/false (which i assume wouldn't be the case for 802.11r-enabled devices).

System:

Ubuntu 20.04.1 LTS, kernel 5.4.0-56-generic
WiFi: Intel AX200
Network: Wi-Fi 6 through Cisco MR56
wpa_supplicant version 2.9

wpa_supplicant config:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=DK ap_scan=1 fast_reauth=1 network={ ssid="####" key_mgmt=FT-EAP eap=PEAP identity="####" password="####" }

Hello Fink,

Thank you for posting on the Intel® communities.

So we can better assist you, please provide the following details:

1. Run the Intel® System Support Utility for the Linux* Operating System and provide the outcome: https://downloadcenter.intel.com/download/26735/Intel-System-Support-Utility-for-the-Linux-Operating...

2. Is this the original adapter that came pre-installed on your computer or did you change/install the adapter to this one?

3. Run the following commands and send us the outcome:

modinfo iwlwifi > If there is no output, then the module isn’t installed this is the distribution installation issue.
lsmod | grep iwlwifi > If the result is empty, the driver hasn't been loaded. Most likely to be a distribution issue.
To verify, please type: dmesg | grep iwlwifi > If the result is empty, the driver wasn’t initialized and this is a distribution issue. If there is a result populated, proceed with the next step.
dmesg | grep “no suitable firmware found!” > If the result is not empty, it means you don't have a suitable FW (api mentioned in the dmesg).
Please visit here: h ttps://wireless.wiki.kernel.org/en/users/drivers/iwlwifi for supported FW, or here https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ for the latest versions.

5. If the above steps don't work, collect the debug data:

Type: dmesg | grep ASSERT

If the output is empty, please follow this wiki: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/debugging to extract dmesg and trace-cmd.

If the output has value, please collect from the wiki FW dump too.

Hi,

I've attached the SSU report.

The adapter was installed afterwards, switching from 802.11AC to 802.11AX.

The output of the commands from step 3 have likewise been attached.

Following the debugging link you sent, i've also attached the dmesg log.
Running ethtool -i wlp2s0 | grep firmware: firmware-version: 48.4fa0041f.0

As for the trace-cmd, am i supposed to be connecting to a network while it's running?
As I said, the device can connect to a device just fine, it's primarily just the over-the-ds functinoality that is not working.

Best regards,
Fink

Hello Fink,

Thank you for the information.

After checking the Intel® System Support Utility for the Linux* I could see that you are using an Intel® NUC Board NUC5i3MYBE.

I would like to let you know that due to compatibility issues, we do not recommend changing the original wireless card of the NUCs. Additionally, the NUC has not been tested to work with Linux*: https://www.intel.com/content/www/us/en/support/articles/000005628/intel-nuc.html

You may want to check with your distro's community for better assistance: https://ubuntu.com/community

Also, due to this product being discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help. You may also find the Discontinued Products website helpful to address your request. Thank you for understanding.

Please keep in mind that this thread will no longer be monitored by Intel.

Hi Sebastian,

We hit this issue as well.

Please confirm if AX210 has the 11r issue on Ubuntu, whether it would be supported.

We are evaluating the AX210 as a potential replacement for AX200.

Thanks,

Asura
