WPA3 not working on Cubot King Kong Mini 2

[sebastian-de]

I'm using AOSP 12.0 v402 (vanilla) on a Cubot King Kong Mini 2, which works great. Thanks for all the work that's put into this project!

The only problem I have is that wifi is unreliable on my device. With the update to Android 12 it stopped working almost entirely, so I tried to look into this problem.

Turns out, that WPA3 doesn't seem to work on the King Kong Mini 2 (and probably more Mediatek devices?). My AP offers both WPA2 and WPA3, but somehow the negotiation seems to fail most of the time. Rarely the phone establishes a connection with WPA2 after multiple failed attempts.
If I create a separate WPA2-only network, the phone connects to that one instantly.

Does anyone else experience this?
And does anyone know, if it's possible to deactivate WPA3 on Android?

In the logs I see this entry, maybe that's related:
02-10 09:53:12.735 1466 1565 E WifiVendorHal: getWifiLinkLayerStats_1_3_Internal(l.1168) failed {.code = ERROR_NOT_SUPPORTED, .description = }

WPA3 not working is expected, however the issue is indeed that Android thinks it supports WPA3.

Fix has already been given to me, it's: followmsi/android_device_asus_flo@04ca9c8
But I need to think it properly so as not to disable WPA3 for people who have working WPA3 hw

Thank you very much for your quick reply and for applying the fix!

I updated to AOSP 12.1 v411 and connecting to my mixed WPA2/WPA3 access point works fine now. Thanks again!
