Wi-Fi Protected Access 3 (WPA3) support #4718

Open ghost opened 3 years ago

ghost commented 3 years ago

I bought a Raspberry Pi Zero 2 W and apparently it does not support my home wifi which uses WPA3.

I excepted that to be the case, since on Debian usually works just fine, and this device is a new release.

It should be at last officialy stated somewhere that is not supported. I basically bought something I can't use.

Notice that WPA3 is not anymore a theory, many commercial routers now ship with it in mixed mode or add that through firmware update.

Side note: actually run just fine on common operating systems from Windows to Android, including Linux if you have no firmware issues.

Is wpa3 possible with debian bullseye with Pi zero w2?

Just to clarify: No, Its not. Just tested myself.

As I understand it, someone is working on an upstream fix, but this is not yet done? Regardless, it will need to be backported to support 'external_auth' for WPA3 on our 6.6.x kernels. This backporting has not been done nor tested. I do not even know if the upstream is built or tested. The current/broken brcmfmac driver on 6.6.x appears to work with NetworkManager/wpa_supplicant. (At least it did with an earlier kernel, I have not tried it lately.) There are still some problems with it, but I have been able to negotiate a WPA3 connection with this setup. It will connect and pass data. I have not been able to with wpa_suppliocant alone, nor with connman and wpa_supplicant. There seems to be some failure of the driver where info is passed from wpa_s to the kernel and it does not accept it, but it seems to 'power thru' and will make a connection with NM/wpa_S.

Once the driver works properly with external_auth on our 6.6.x kernel with wpa_supplicant, I believe the development of iwd to support WPA3 can be started, but until the driver is fixed, I do not think that will start.
