I have just flashed a copy of openwrt 19.07 to my GL-USB150 router. I replaced wpad-basic with wpad-openssl and found that I could set the wireless security to wpa3-sae.
I successfully connected my laptop running Windows 10 1909 and got internet access. I am very pleased with this.
I usually run ubuntu on the laptop, but this I couldn’t get it to connect. I suspect the DKMS driver for the rtl8821CE wireless chip because it wouldn’t connect when PMF (protected management frames) was switched on in the router.
The GL-USB150 uses the Ath9k driver for the Qualcomm QCA9331.
Has anyone else tried WPA3 yet?
