Intel WiFi with WPA3-Personal & GCMP (Solved)

RouterOS Wireless Networking
1

Hi!

Just wanted to check… has anyone else noticed problems getting Windows devices with Intel NICs working with WPA3 & GCMP 256?
Intel’s product brief for the NICs indicate that they are compatible with WPA3, 128-bit CCMP, and 256-bit GCMP. However, only 128-bit CCMP seems to actually work.
The Android devices I have to test with (Pixel 7 Pros) work with literally any valid configuration of WPA3-Personal.

CAPs: Audience
RouterOS: 7.13.3 w/ wifi-qcom-ac package

Thanks for any insight!

Hello @goodbye,

Yes it’s a known behaviour, see here https://help.mikrotik.com/docs/display/ROS/WiFi#WiFi-SecurityProperties, look at encryption part, there is a special remark for intel cards.

Best regards,

Try this at a windows command prompt it should show you.
netsh wlan show drivers

Thanks!
But this chip with the latest drivers (or, really, drivers from last year) should support both gcmp-256. And yet…

That’s actually gives a lot of insight, and definitely shows Intel’s shenanigans.

WPA3-Personal(SAE) and OWE only support CCMP
WPA3-Enterprise only supports GCMP-256

That’s… wow.

Thanks for pointing this out!
