Blue screen during using WIFI with 6G band

Bigforce · ‎04-06-2025

I meet a critical issue with my newly purchased YOGA slim6 and ThinkPad T14s with Intel AX211 160 WIFI6E network adapter. It will frequently blue screen and restart if there are many APs (WIFI access point) with 6G band around with the same SSID. I have tried many times and restarted many times, and I found that the threshold of the number of APs to trigger the issue is about 70. If there are more than 70 APs with 6G band searched by my PC, the blue screen will definitely appear. It would never happen in any area without so much APs. Maybe many of places does not have so many APs, but in my office there are. So, I cannot use WIFI with 6G band now.

There are many PCs with Intel AX211 & BE200 network adapter and many of them meet the issue too. Please help to take this issue seriously and resolve it as soon as possible. Thanks!

Hello Bigforce,

Thank you for posting in Intel community Forum.

For me to further check this, please help provide the following details:

Did you upgrade the wireless controller or this is the embedded wireless controller of your laptop?
Was it working fine before?
Did you change any settings before the issue started?
What is your OS?
What are the troubleshooting steps that you tried before?

If you have questions, please let us know. Thank you.

Hello Michael,

Thanks for your response.

1. Did you upgrade the wireless controller or this is the embedded wireless controller of your laptop?

Sure, I have tried to upgrade many of driver versions from 22.140 to 23.120, all of them meet this issue.

2. Was it working fine before?

It works well in most of scenery, but if I get in this new and special scenery (with many of APs), the issue will occur.

3. Did you change any settings before the issue started?

No. Many of my laptop meet this issue, some are old and some are newly purchased. We also tried upgrade/downgrade Windows 11 version to test, it still no help.

4. What is your OS?

It's Windows11 24h2. We tried 23H2 & 22H2 and the result is the same.

5. What are the troubleshooting steps that you tried before?

We tried upgrade/downgrade the driver version of AX211/BE200, upgrade/downgrade WIN11 OS version, tried Lenovo/Huawei laptop, tried Huawei/Aruba access point, changed the 6G band channels and many of other parameters on AP and so on, but these actions all useless. It is only related to the numbers of APs with the same SSID.

When I changed my wireless network adapter to Qualcomm WIFI6E network card, the issue disappeared. So, I can conclude that this issue is only triggered by Intel network card, other vendors do not have this issue.

Looking forward to your response.

Best Regards,

Hello Bigforce,

Thank you for the update.

Base on your reply, let me ask some questions.

Did you also purchased the Intel AX211 separately?
If it is causing BSOD, it is also possible that this is a hardware issue. If this was not purchased separately, have you tried contacting the manufacturer of the laptop for further diagnostic?

If you have questions, please let us know. Thank you.

Hello Michael,

The Intel AX211 adapter is integrated in my Lenovo laptop. I am sure it's not a hardware issue, because I have many laptops meet this issue, include Lenovo/HP/Huawei with AX211/BE200, all of them meet this issue. And also, I have some laptops with Qualcomm and MediaTek WIFI 6E adapter, they all work well.

I have posted a ticket to Lenovo, but I think they will also need to ask Intel at last. So, I post here to make it more efficient.

This issue is only happed in WIFI 6E(6G) band environment. Maybe few users met this issue currently, but the issue becomes more and more critical, because the WIFI 6E and WIFI7 AP used more and more, the BSOD is unacceptable for users.

I have uploaded the logs of my laptop, if you can analyze it, you will know the BSOD is caused by Intel driver.

I already know the pattern of how to trigger the issue, as I said before, it's more than 70 APs around the AX211 and AX211 preparing to roam. You can ask R&D to check the code, what will be happen when the AX211 decide to roam, when it have more than 70 APs as the candidate works in 6G band. It's a definitely issue in this case, and almost I told you where the bug is, it would be easy to find out the root cause by Intel. I wish you can solve it ASAP. Otherwise, I have to change the wireless adapters to other vendors, it's a real big work for my team.

Thanks again and please help to take it seriously.

Best Regards.

Hello Bigforce,

Thank you for the update.

The reason why I asked if you already tried to contact the manufacturer of the laptop is because Intel drivers are generic drivers.

OEM or laptop manufacturers can alter/modify/enhance the controllers since it is being controlled by their BIOS and those enchantments are unknown to us and to enable to changes, they may have their own drivers.

However, don't worry. I will also have this checked by our Engineers. Please help to generate the SSU logs of your system for further investigation.

Kindly refer to the link below on how to generate the logs:

Hi Michael,

Thanks for your reply.

Okay, I have posted a ticket to Lenovo, but I think it's not related to OEM manufacture, because the Lenovo and Huawei laptops both met this issue.

I have collected the SSU log of one laptop at my home (not office, only office can repeat the issue), please help to check first. If you need more logs or information, please feel free to tell me, I can share you everything in this laptop. Thanks again.

Best regard.

Hi Michael,

I have done the clean install with the latest driver, but the issue still exists. And also, I have collected the SSU log at my office, the blue screen issue happened 3minutes ago. Please help to check. Thanks!

Best Regards.

Hello Bigforce,

Thank you for the update.

Did you already reported this issue to Lenovo to further check this issue?

If you have questions, please let us know. Thank you.

Hello Michael,

Yes, I have reported this issue to Lenovo team and their have done some check, but nothing found as my prediction. They cannot solve this issue without Intel help.

And I also reported this issue to Huawei team, they analyzed my logs and told me that this issue is caused by Intel driver, but currently they cannot submit ticket to Intel. So, they suggest me to request help here. This conclusion also matches to our test results -- Qualcomm and MediaTek wireless adapters never met this issue.

Best Regards.
