[mailsanchu]

Hi there,

My Intel AX210 is crashing after enabling  802.11ax / WiFi 6 mode on my ASUS AX86U.It works fine otherwise. Speeds are around 400-500Mbps on a 1Gb connection. I am attaching some basic info here. Happy to share additional info if required

Hello mailsanchu, 

In order to proceed, please try and provide the following:

1. What is the brand and model name of your router?

2. Did the issue appear on windows 10/11? Or is it only limited to Linux as you mentioned?

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: 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.  

4. 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 it from the wiki FW dump too.

Deivid,

Firmware is working correctly for 2.4/5Ghz. So it is a firmware issue.

Does your firmware support 6GHz?

[mailsanchu]

1. What is the brand and model name of your router?
>> ASUS AX86U

2. Did the issue appear on windows 10/11? Or is it only limited to Linux as you mentioned?
>> Windows 11 is OK and no issues

Attached modinfo and lsmod logs

Deivid,

Looking forward to the solution. Thank you 

[DeividA_Intel]

Hello mailsanchu, 

Based on the research perform, I would like you to try and provide the following:

1. Update to the latest firmware version 67 and check if the issue persists.

2. Check with DELL and confirm that the latest BIOS is installed.

3. Check that the AP is using the latest firmware.

4. You mentioned randomly firmware crashes during data streaming while connecting to Asus AP at 5 GHz in 20 MHz bandwidth, but 2.4 GHz works fine?

5. Does the firmware crashes after "x" hours of streaming?

Best regards,

1. Update to the latest firmware version 67 and check if the issue persists.

>> How do I update the 67 firmware. Any documentation for this?

2. Check with DELL and confirm that the latest BIOS is installed.

>> Yes I check this regularly 

3. Check that the AP is using the latest firmware.

>> Yes I check this regularly 

4. You mentioned randomly firmware crashes during data streaming while connecting to Asus AP at 5 GHz in 20 MHz bandwidth, but 2.4 GHz works fine?

>> Don't think this is happening. Only WIFI 6 is the problem

5. Does the firmware crashes after "x" hours of streaming?

>> Dont think this is a problem

[DeividA_Intel]

Hello mailsanchu, 

Thanks for the information provided. In this case, I recommend you to get in contact with the Linux support team to get the steps and firmware to perform the update.

Please let me know if the issue persists after the Firmware update.

What do you mean by "Linux support team"? Linux support team from intel or 

Not sure I follow

[DeividA_Intel]

Hello mailsanchu, 

In this case, you need to check with DELL or with your Linux distributor (or where you downloaded the operating system) for firmware and instructions to update it.

Intel does not have a Linux driver nor provides steps or drivers/firmware.
