Wifi doesn't connect to protected networks on AOSP14 and AOSP15

[KonstaT]

Connecting to WPA2/WPA3 networks doesn't work on Android 14. Connecting to open networks works as expected. There is nothing apparent in logcat output that would indicate the exact issue. Behavior is similar to inputting a wrong password for the wifi network. There is also no issue with creating a WPA2 protected wifi hotspot on the device.

This would likely indicate some issue with WPA2/WPA3 authentication or wifi keystore that was changed in Android 14.

Connecting to WPA2/WPA3 networks is successful when wpa_supplicant and wifi supplicant HAL from Android 13 are used instead. There's a package with the binaries available here.

I've included patched AOSP 13 external/wpa_supplicant_8 in android-14.0 branch to workaround this issue.

You might also need following patch on system/libhild for the fancier authentication features (WPA Enterprise, etc):

I'll leave this issue open for discussion as I would rather find proper solution for this.

Unsurprisingly did not magically fix itself in AOSP15.

Comment above still stands and I've provided patched external/wpa_supplicant_8 in android-15.0 branch to workaround this issue.
