I've been playing with the Rock 4C+ Starter Kit, great hardware!
I connected the ethernet cable, SSH, ok. Set WiFi as follows:
sudo nmcli r wifi on
sudo nmcli dev wifi connect ”<ssid>” password “<password>”
It took a while but worked.
Switched off, moved to another place (close enough). It doesn't connect to WiFi, any clues? Thank you.
Edit: hardware reboot, it connects. If there's a power outage it doesn't reconnect when power comes back, I need to manually power cycle to have WiFi working again.
