6GHz not available after Reboot with Airplane Mode
After I switch Airplane mode off and search Wifi again the 6GHz Band based SSID will found, I think this is a major Android / Pixel issue, on Stock Android 16 QPR2 Beta I think the issue exist too here. After the connection is there now I can switch the Airplane On and all still works. I notice this after Reboots.
I have the Pixel 9 Pro XL with latest Alpha Channel GraphenOS installed.
My AP is a TP-Link 773 switching Channels or Mhz Width doesn't change anything for me.
