I have GrapheneOS on my Pixel 6A. As I changed provider, I have a Draytek Vigor 2765 modem for WIFI at home. With the laptops and Iphone no problem connecting to the WPA3 network on the Draytek modem. The only problem I have is with my Pixel 6A. I can not connect to the WPA3 network on the Draytek modem. I contacted the helpdesk of Draytek. They indicated that it must be the Pixel (or OS) causing the problem. For now they have created a WPA2 network, so I can connect the Pixel with the Draytek modem. As I want the Pixel to connect with the WPA3 network, I have reset Bluetooth and Wifi under Settings on the Pixel phone, to no avail.
Any suggestions what I can do about it?
