Hi there,
I am an engineer from H3C, I have found that be200 clients supporting MLO will go offline after associated with our APs by sending a deauth. The driver version of be200 is 23.120.0.3. The client associated to our AP with 6G+5G MLO link combo, as a result, the clinet's mode is EMLSR. However, after working 3-4 minnutes, the be200 will go offline with sending a deauth to our ap and with no reasons. So is any possible to get a debug sw from you to figure out why be200 sending deauth to go offline? (We have also checked the wireless report and found tyhe client reported err code 1104---wireless security services stop, but no further info on why the clients send a deauth).
Thanks,
BR

Hello Bowin,
Thank you for posting in Intel Communities.
To better understand and be able to identify the root cause of this issue, please help share the following details below:
1) What systems (make and model) are affected?
2) What troubleshooting steps has been tried to fix the issue?
3) Please share the wireless report with "reported err code 1104---wireless security services stop".

Hi Jeanette,
I do not think this issue has the same root cause of Warning Error in Event Log: "deauth after EAPOL key exchange sequence".
For the BE200 clients can go online with our AP and work normally for 2-3 minutes with DL throughput. Is it any possible to use some software to debug and figure out the reason why clients send deauth to AP?
1) What systems (make and model) are affected?
Actually, I am the RD of H3C Technologies. AP provides a 6+5 MLO combo. We used Lenovo thinkbook (windows 10) which originally adapted with its own wireless driver, we replaced its original wireless driver with the BE200 hardware and software either. So, I think its much related to our AP or BE200. However, its hard to figure out the root cause with the deauth sent by be200. As a result, we want to request you to help us find out the Root Cause why be200 sends deauth after working normally for a while.
2) What troubleshooting steps has been tried to fix the issue?
We suspected that our AP may not response some kinds of packets sent by BE200, with capturing the packet int the air, unfortunately, nothing seems unusual. Its kind of wired that BE200 could go online with our AP and make 2.6G DL throughput with 2-3 minutes. Then the BE200 goes offline our AP with sending a deauth.
3) Please share the wireless report with "reported err code 1104---wireless security services stop".
sorry, I made a mistake. The err code is 11004 as the attached figure shows. Beside, I got the log of SSU64.exe produced when the issue occurred, is this useful for analyzing the problem.
Appreciate it much.

Hello Bowin,
Please read the information below.
1. Intel ® Wi-Fi 7 products support MLO, but their features and compatibility may vary depending on operating system, wireless access point (AP), and national regulations.
2. Regulatory authorities in some countries prohibit the use of the 6 GHz band. It's also possible that the system manufacturer hasn't enabled this feature on your platform.
Intel recommends that you check to see if the regulations in your country allow the use of the 6 GHz band and whether the system manufacturer allows the device to support the 6 GHz band in your country.
Reference Document: https://www.intel.com/content/www/cn/zh/support/articles/000059385/wireless/intel-wi-fi-6e-products.html
3. Regulatory information about the installation or upgrade of wireless hardware
Since each country may have different regulatory requirements, you must contact the system manufacturer before installing/changing the Intel ® Wireless Adapter in your system, to determine if the Intel ® Wireless Adapter you plan to install is approved for use in your system and country. You need to follow the manufacturer's post-approval requirements.
I hope these information helps.
Sincerely,
JeanetteC.

Hi Jeanette,
I have confirmed that AP and BE 200 clients both support MLO. Is it possible to use any debug software to find out the reason why clients go offline. Since other 6G MLO clients, such as Android terminals, will not go offline with sending AP a deauth.
Thanks.
BR.

Hello Bowin,
To address this issue, I recommend reaching out to your OS (Win11 Pro Insider Preview Build 27808) manufacturer's support team to verify if it supports MLO. Additionally, please be aware that if your country has regulatory restrictions on 6GHz usage, it might affect your setup. It would be beneficial to test if the issue persists with MLO using 2.4GHz and 5GHz frequencies. If these frequencies work, you may need to coordinate with your system manufacturer to check for any available BIOS or firmware updates that support 6GHz.
I hope this information is helpful. As this thread will no longer be monitored, please feel free to submit a new question if you need further assistance in the future.
Sincerely,
JeanetteC.

Hi Jeanette,
Honestly, I think that we have made this issue completely complex. It is very simple to see the reason why clients go offline from your sides, but rather difficult from the AP's. I am very confused that does INTEL have no debugging software for the be200 driver? It is hard to guess the root cause of this issue without logs .
Thanks.
BR
