KDE Plasma not detecting Broadcom WL

Please help.
I installed Arch in my old Macbook Air 2012. Eveything seems fine except wifi interface not showing in Plasma, even though during install iwdctl detected it. It seems arch is detecting the driver, but plasma not. Not sure where the problem lies.

broadcom-wl-dkms and linux-headers installed.

Please a hand! There is pressure behind.

lspci -vnn -d 14e4:
BCM43224
Capabilities: <access denied>>
Kernel modules: bcma

Might this be related to a permission issue? (Capabilities denied)

Thanksss!

Re: KDE Plasma not detecting Broadcom WL

No Arch is not detecting the driver, the driver it detects is the open source in kernel module that is blacklisted by broadcom-wl-dkms and not loaded, you'd see a "Kernel module in use" line if it was.

Check/post

sudo dkms status

in [ code ] [ /code ] tags. Chances are the current broadcom driver is incompatible with the 6.4 kernel series, test linux-lts and linux-lts-headers.

Re: KDE Plasma not detecting Broadcom WL

Thank you for your reply, it really allowed me trace the problem.
I had installed the realtime kernel 6.3.3, which I need for audio, but mistakenly the normal headers. Installing the rt headers solved it, which are needed by dkms drivers.

Thanks again! Solved
