Intel(R) Wi-Fi 7 BE201 320MHz frequently reconnect or cannot find internet adaptor

[naht]

Background: 

The driver is latest release 23.140.0.3.

None of the following methods helped, including re-install driver and reboot.

The computer is ASUS GU605C. 

I have tried to re-install win 11 system once, but the problem was just solved temporally and appearred again.

I have noticed that everytime the internet diconnect with an error (event ID 5055 from source Netwaw16) and a following warning that the WLAN expansion module has been deactivated. 

These events ID in shown order have appeared every time with diconnection. That information from kernal power shows "standby connection status: disconnected    Reason: NIC compliance"  (machine translated)

In addition, it seems I have similar issue in this post Netwaw16 Has determined that the network adapter is not functioning; adapter stopped working - Intel Community . Wish it could be helpful!

I wonder whether it is a problem in software or hardware and hope any suggestions could be given. Many thanks!

Hello naht,

Thank you for posting in Intel Communities.

To better understand the issue and provide an effective recommendation, please share the following key information:

1. Is the wireless adapter (Intel® Wi-Fi 7 BE201) pre-installed on your ASUS GU605C device, or is it an upgrade component?
2. Has this component functioned properly before, or is this an out-of-the-box issue?
3. If it worked fine previously, what changes were made before the issue arose?
4. Please provide a screenshot of the status in Device Manager > Network Adapter > Wireless BE201 Properties.

Additionally, I would greatly appreciate it if you could share your system configuration so I can thoroughly check and offer an accurate solution. This could be possible by downloading the Intel® System Support Utility for Windows* software. When the download is complete, launch SSU.exe.

• Scan: Check the box Everything.
• Click Scan.
• Review: When finished scanning, click Next.
• Click Save. *Attach the SSU log file as you reply.

I look forward to your response.

Best regards,

JeanetteC.

Hello JeanetteC,

This adapter is pre-installed and only functioned properly at its first several hours since I received the laptop.

I have checked if there are out-box factors but none of my other devices have similar problem, included another laptop, and I also replaced my wifi with a better one that supports wifi6/7 but the issue still exists. 

Mostly, while the issue arose, I was downloading or playing video games. I also found a method to alleviate but not solve this problem: 

Switch the wifi mode to 802.11n and 2.4G channel width to 20MHz.  

The result would be longer seperation (between each disconnection) or less probability to disconnect, though much slower internet.

Here is the screenshot for the properties of 320MHz. The status shows: This device is working properly.

Wish any idea of this issue could be found. Thanks for helping!

Hello naht,

Please perform a clean installation of the latest OEM driver (version V23.130.1.1). Additionally, review the Recommended Settings for 802.11ax Connectivity. Let me know the outcome.

Best regards,

Hello JeanetteC,

I have tried them both but the problem still exists, especially when I connect 5Ghz which would disconnect about every 1 minute.

Additionally, I have tried to download 23.130.1.1 from intel website (Simply because I forgot to click this link V23.130.1.1), but it is weird that everytime after I uninstall the OEM driver, the install program does not allow me to continue since "already a driver detected". Thus, I guess I could not completely unintall the driver from driver manager: some corrupted driver pieces maybe? 

For Recommended Settings for 802.11ax Connectivity, I have tested 802.11ax, be, ac and n, but only in 802.11n the stability seems better.
