Arch Linux

Description:

After performing a system update using yay and rebooting, the wireless network interface was not present anymore.
Running "ip a" command only reported the loopback interface while it previously returned the interfaces for "lo" and "wlan0".

Running: "lscpi -vnn" / "lspci -k"
correctly reported the ethernet and wireless adapters were detected

The only relevant error message reported by "dmesg" was this one:

mai 04 22:19:05.060798 mac kernel: cfg80211: Loading compiled-in X.509 certificates for regulatory database
mai 04 22:19:05.064125 mac kernel: cfg80211: Loaded X.509 cert 'sforshee: 00b28ddf47aef9cea7'
mai 04 22:19:05.064219 mac kernel: platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
mai 04 22:19:05.064524 mac kernel: cfg80211: failed to load regulatory.db

After plugging an usb/ethernet adapter I got internet access again and installed the wireless-regdb package (along with updating the system again) and rebooted. After the reboot, the wlan0 interface was present and correctly setup.

Seems like broadcom-wl should explicitely depends on wirelss-regdb package.
