Rock3c unable to connect to wifi
Please try sudo nmtui.
Turns out that ubuntu is not officially supported and the images are provided without testing. Despite having names like “rock-3c_ubuntu_jammy_cli_b33.img.xz”, that I would suggest is somewhat misleading and may give the impression they are official, or any real description to tell you they are provided as is without support. Please see https://github.com/radxa-build/rock-3c/issues/4.
Edit: Sorry I now see you’re using debian
Got a Rock 3C a couple of days ago from OKdo and didn’t have any problems with WiFi. I’m using Debian. Just put in my router password and it worked.
used Debian，3C can connect to wifi。thank you for help。
