Yesterday I installed Artix on an Acer notebook (ES1-251 with an AMD quadcore CPU). All was right since I had to interact with the WIFI: no way to activate it, both the internal wifi card and every USB dongle.
Very strange cause it worked perfectly with Manjaro (I replaced Manjaro with Artix).
After some trouble and dark thoughts... the solution has been:
1) sudo nano /etc/modprobe.d/blacklist.conf
2) insert the line: blacklist wmi
3) save and reboot.
All work immediately and rfkill stopped to see a hw block to the wifi card. I suspect that this solution may be useful also for other wifi cards. Looking inside the dmesg log, I discovered a wrong load of the wmi module. We can survive very well also without it :D
Excellent troubleshooting, again!
What does the wmi module do? I's description reads: "ACPI-WMI Mapping Driver".
