Hi and welcome to !
I suggest using the proprietary Broadcom drivers from RPM Fusion. For that you would need to:
- Add the RPM Fusion repos, if not already done, according to these instructions.
- Install the
broadcom-wl
package withsudo dnf install broadcom-wl
. - Wait about 5 minutes for the kernel modules to get built[1].
- Reboot and check that the
wl
module is used, and WiFi is functional.
The kernel modules are being built with every new kernel installed on the system, so it is advisable not to reboot immediately afterwards. The process of building the modules is finished when the
ps -ax | grep kmod
command only returns one line: the one with the grep command. ↩︎
