Intel AX211 speed drops untill adapter restart

[Paul1477]

Hi,

I am using a  Intel® Wi-Fi 6E AX211 (160mhz) adapter on an ASUS Z790 A Wifi motherboard via a fiber optic connection.

Normal speeds (after rebooting the computer or restarting the wifi adapter via windows) are a  ping of 8ms , download 850mbps and upload 575 mbps.

The connection speed drops however within minutes to a ping of 450ms , download of 10mbps and upload of 10mbps. 

Other devices connected to the same wifi don't have this issue. The speed goes back to normal after restarting the wifi adapter via windows.

The motherboard is updated to the latest bios and the adapter is running the latest intel driver. I am running Windows 11 Pro 23H2

Hello Paul1477,

Thank you for posting in our communities.

May you please check to see whether the WiFi card has been loosening up on your motherboard? Given that you said it only occurs on this particular device, it's possible that the WiFi card has become loose.

Furthermore, may we also know when the issue started? Was the connection speed on your system working fine before? If yes, have you made any changes before the issue occurred?

And also, please generate an SSU report to help me further analyze important details on your system, such as the exact drivers on your system, etc. To generate the SSU report, please refer to the article: How to get the Intel® System Support Utility Logs on Windows*. Please send us the generated SSU.txt file.

We look forward to your response!

Best regards,
