Connman bug "Error /net/connman/technology/wifi : No carrier" - a workaround
After two years, suddenly connman WiFi scan ceased to work and I'll write this post to help anyone who will face this bug in future
I don't often use WiFi, so i don't know with precision when this happened, but it was after January (the lat time i used WiFi on my notebook) so i don't know either what update was the culprit.
Investigating leads me to the arch forum wiki .
I saw some posts also here on the Artix forum suggesting substituting connman with network manager as only solution to the problem.
I don't want leave connman so i try deepen the question, without luck..... It seems there is no way to solve this problem.
As last resource i try to launch connmand from cli, and it threw this error:
error fi.w1.wpa_supplicant1.UnknownError
wpa_supplicant works well for me so the problem is in connman wpa_supplicant interface.
So instead to substitute connman with NM i switched wpa_supplicant for iwd.
In Artix it is as simple as remove all wpa_supplicant related packages and install iwd and iwd-your_preferred_init.
Obviously change "your_preferred_init" with the init system you are using 
Now connman works flawlessly, again.
