Re: 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.

Mike_Intel · ‎04-13-2025

Hello Bigforce,

Thank you for the update.

Can you try to install the latest generic driver using clean driver installation method then observe the system.

Please refer to the links below for the driver download link and the steps for clean driver installation.

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.

Mike_Intel · ‎04-15-2025

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.

Has there been any resolution to this issue? We are running into an identical scenario with AX211 WiFi cards in Dell Laptops, Dell points to Intel. We have just under 800 APs with 6GHz turned on in our warehouse. If you turn off 6GHz on the wireless Adapter than the laptop works fine! Tried clean install of Windows 11, and also the clean install of the Intel Drivers. Nothing seems to resolve this issue!

Bigforce · ‎05-30-2025

Not yet. Currently we are working on resolving this issue with Intel engineer. There is only one workaround which is to turn off 6G band.

How do you have so many APs? In my office, there are about more than 100 APs at one point, and I think it is too much.

And may I ask what is the model of your APs?

SuthamK · ‎05-29-2025

The same issue occurs across all Dell laptop models equipped with the Intel(R) Wi-Fi 7 BE200 320MHz adapter. These devices experience a BSOD with error code 0x0000007E (0xFFFFFFFFC0000420, typically about once a week.

We have been able to reproduce the issue several times by putting the device into sleep or hibernate mode for over 60 minutes. Upon waking the device, it immediately triggers a BSOD.

All devices are using the latest Wi-Fi and Bluetooth drivers from Intel’s website.

Access points are Aruba AP-515, running on 5GHz, support Wi-Fi 6 (not using Wi-Fi 6E or 7).

Next, we’re planning to try the Intel Modded Wi-Fi Driver with Killer features to see if it helps.

Bigforce · ‎05-30-2025

It seems a new issue.

The issue I met only happen with 6G band signal. When I disable WIFI6E or the AP does not support WIFI6E, the issue would not happen.

And it would not happen with any NIC which does not support WIFI6E, such as AX200, AX201.

Reciprocity · ‎08-13-2025

OMG....this has been driving me crazy. Thank you.

Windows button + x will get you to Device Manager

Locate Killer Wifi in Network adapters
Right click and go to properties and under Advanced you can change the 802.11a/b/g Wireless Mode from 6 to 5 and no more BSoD! I can connect to my wifi enter the password and just be online.

Thank you!

Donalic · ‎08-31-2025

Are there any updates to this issue from intel side?

Just wondering what APs are you guys have? My office is using Huawei APs for the whole campus.

Bigforce · ‎09-02-2025

Good news. The 23.160.0.4 just released have solved this issue, you can have a try.

We also use a large number of HUAWEI devices, and the experience is excellent.
