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 (22.160.0.4/22.170.0.3) 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 (22.170.0.3)

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 !

CASE 05604856 (started 9th september 2022)

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

UNI3 (5 GHz : 149, 153, 157, 161 & 165)
