Installing broadcom wifi drivers

@sabrina and others… I checked an iMac 21.5" (iMac16,2 non 4K) from 2015, with Fedora Linux 37 installed, using inxi -n and get the message that there is no driver for the built in Broadcom BCM43602 installed.

Network: Device-1: Broadcom BCM43602 802.11ac Wireless LAN SoC driver: N/A

I reboot the same iMac from the official Fedora Linux 37 Live iso, “burned” to an USB Stick, have to sudo dnf install -y inxi to install the inxi utility and run the command again, getting the following result:

Network: Device: Broadcom BCM43602 802.11ac Wireless LAN SoC driver: brcmfmac IF: wlp3s0 state: up mac: 00:00:00:00:00:00

Conclusion: on the Fedora Linux 37 Live iso the Wi-Fi driver for this iMac is present, however it does not get installed onto its SSD when installing Fedora itself. Booted from the Fedora Linux 37 Live iso Wi-Fi can be configured and used to traverse the internet, however when booting from the installed iMac no Wi-Fi adapter is found and with that, no Wi-Fi network can be selected and used.

So the drivers are available on the Live iso, now how to get them into that installed Mac, or your machine as well…?

1.) Enable rpmfusion free and non-free repositories, see Configuration - RPM Fusion

2.) sudo dnf install broadcom-wl, see broadcom-wl | Package Info | koji

3.) reboot
