Intel chipset AX201 does NOT support UNI3 channels !


I have found on many laptops with an Intel chipset AX201 that windows 10/11 does NOT support UNI3 channels. If I test the same Laptop with Ubuntu (then the UNI3 channels are recognized and supported).

I have tested this with Windows 10 (20h2 / 21h2) and latest windows 11 ( in the Netherlands (REGION)

With this I proved that the AX201 hardware does support it. The problem is not solved even in the latest Windows software version (

I cannot connect to a wireless network if the UNI3 channels are not supported in Windows. So I can NOT provide logs  (Intel iWFT tool) I would like to get in direct contact with Intel Wi-Fi developers.


With there existing testing process  I can't convince the Intel Customer Support and i have shared a wireshark capture !

In the Netherlands, the UNI3 channels were released a long time ago....
