Intel AX201 – Windows cannot scan 5GHz lower & middle channels (36–48 & 100-144)

Hi Intel Community,

I’m currently troubleshooting an issue with Intel Wi-Fi 6 AX201 on Windows 10/11 in an enterprise office environment.

Environment details:

Client devices: Windows laptops with Intel AX201 (latest Intel driver installed)
OS: Windows 10 & Windows 11 (64-bit)
AP vendor: Ruckus
Network type: Enterprise Wi-Fi (5 GHz primary)
Country where laptops were purchased and used: Indonesia
AP country code: Philippines
802.11d: Enabled on the AP

Issue observed:

On Windows laptops using Intel AX201, the Wi-Fi adapter cannot scan or see 5 GHz lower channels (36–48).

The SSID is not visible when it is broadcast on those channels.

However:

The same SSID is visible on macOS devices
Windows clients can see the SSID when it is moved to higher 5 GHz channels
This behavior is consistent across multiple AX201 laptops

What we’ve already tested:

Updated to the latest Intel AX201 Wi-Fi driver (non-OEM)
Reset wireless profiles and network settings
Verified that 5 GHz is enabled and preferred in adapter advanced settings
Confirmed AP configuration and channel legality in the local region

Questions:

Is this expected behavior when there is a regulatory domain mismatch between the client (Indonesia) and the AP (Philippines) while 802.11d is enabled?
Does the AX201 driver strictly block scanning of certain 5 GHz channels in this scenario by design?
Is there any supported way to confirm which regulatory domain the AX201 driver is currently enforcing?
Are there any recommended best practices or driver settings to allow seamless operation in mixed-country AP environments?

Any guidance or confirmation from Intel engineers would be greatly appreciated, especially to help us determine whether this is a driver limitation or a compliance-related behavior.

Thank you in advance.
