I deleted the network setting in control panel by accident, now I can't find it back. I can still see my network device (enp0s20u4u4) in ip addr. How to fix it, thanks
Welcome to Manjaro!
Please read this:
and post some more information so we can see what's really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies...
P.S. If you enter a bit more details in your profile, we can also see which Desktop Environment you're using, which CPU/GPU you have, ...
Sorry for posting without detailing, I updated my profile, and the followings shows my hardware information with command $
inxi -Fxxxza --no-host.
BTW, it's fine now, idk how I fixed, I unplugged my usb network adapter and reboot, after that, I plugged it again, and it works.
Thank you for your replying.

You're welcome. As the problem went away all by itself, I removed the solution so that others looking for a solution will not have this answer come up as "solved" (but giving me the solution was appreciated, and in return! )
