Re: Re:Intel AX200 (iwlwifi mvm driver), issues in AP_mode IEEE802.11ax, Linux

RS19104 · ‎03-01-2021

Hello, we are currently working with different Intel AX200 boards in Linux, both as stations and AP. Unfortunately, we are not able to make IntelAX200 run in AP_mode, IEEE 802.11ax.

Configuration:

Linux Kernel 5.8

2. Iwlwifi-backport core56 (and have also tested other)

3. Hostapd-master (2.9 and 2.10 developer version)

4. Ubuntu 20.04.1

Configuration on STA:

1. Linux Kernel 5.8

2. Iwlwifi-backport core56 (and have also tested other as suggested by Intel)

3. Ubuntu 20.04.1

The support by Intel has lead to several tries, which still do not allow for Intel AX200 to run in AP_mode.

In attach goes a zip with the following docs:

1. Details : Explanation regarding the crash issues; the types of configuration tested and result.
2. dmesg_AP : dmesg output of the AP where crash can be observed
3. dmesg_STA : dmesg of the STA trying to connect to AP
4. Wireshark-AP-STA : Wireshark capture of the frames exchanged when crash occurs
5. hostapd : hostapd logs in debug mode.
6. hostapd_cli : This files contains the output of the stations connected to or trying to connect to AP.
7. Gmail - Configuring WiFi6 in hostapd : This pdf contains the mails exchanged in hostapd mailing list.
7. sample: This folder contains a wireshark capture of a successfull connection between AP and a STA in 802.11n mode.

Note this is a follow-up from @Shm posts between Sep and December 2020.

RS19104, Thank you for posting in the Intel® Communities Support.

In reference to your inquiry, please try the following troubleshooting steps in order to determine if there might be a problem with the Wireless configuration:

WiFi troubleshooting steps

Step 1: Check whether the kernel version supports this device:

The reference table of Wireless adapters and corresponding kernel versions is available in the following link:

https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi

The latest FWs are available by the following link:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/

If the kernel version corresponds to the Wireless adapter, proceed with step 2.

Step 2: Check whether the Wireless adapter is connected correctly:

Type the following command to the terminal: # lspci

Verify that the Intel network controller is identified, as on a picture below. If not, then the system doesn't identify the Intel networidentifyk adapter and you will need to make sure it's properly integrated. You may need to request help from the system manufacturer. If the wireless adapter is properly identified - proceed with the step 3.

Step 3: Check whether this is an iwlwifi issue:

Type the following command to the terminal: # modinfo iwlwifi (example of the command output is on the picture below). If there is no output, then the module isn’t installed this is the distribution installation issue.

Please type: # 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 the result is populated as on the above picture, proceeed with the step 4.

Step 4: Check whether the suitable firmware is installed:

Please type: # 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 https://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.

If these steps didn't reveal the issue or didn't solve the problem, proceed with the Step 5:

Step 5: Collect the debug data:

Please 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.

Any questions, please let me know.

Regards,

Albert R.

What was the fix for this? I am trying to get an AX201 to work on a system where AX200 and AX210 failed also. Thanks.

RS19104 · ‎05-25-2021

Hello

upgrade to kernel 5.11.6

upgrade the used microcode to .59 (iwlwifi-mvm)

We see some problems with the rates sometimes (not clear if it is a problem with the boards or hostapd as the documentation does not help), but it works.

Tremain · ‎05-25-2021

I might have found the problem but I don't know how to test it. Ubuntu is trying to load the iwlwifi-QuZ- microcode instead of iwlwifi-Qu-. I attempted to delete all of the iwlwifi-QuZ but then the AX201 isn't recognized at all and no firmware is loaded until I restore the iwlwifi-QuZ. Dmesg shows that it's failing to load QuZ but then loads it anyways, apparently never bothering with the Qu.

Btw, dmesg shows that it is being detected as an AX201:

Hi, in my case using that kernel and even that firmware does not work. Reg domain can't be changed and then, AP mode for 5Ghz will not work.

There must be a way to disable DRS/LAR in Linux with newer kernels...

Anyway in Intel can reply to this please? @Alberto_Sykes
