No Wifi Connection in Network Connections; No Wifi Networks; Using BCM4360 Wireless Network Adapter

I am running Manjaro (kernel 5.9.11-3) with a Broadcom BCM4360 network adapter.
I read a few posts on the forum for people with similar issues, but cannot seem to get my wireless network adapter working.

The inxi -Fxxn command produces the following:

I tried following this forum post closely, which included blacklisting other Broadcom drivers and installing broadcom-wl-dkms.
When I tried installing the broadcom-wl-dkms module, it didn’t appear to install properly.
This is the output I get when running pacman:

[matt@matt-linux ~]$ sudo pacman -S broadcom-wl-dkms

To load the new module, run as root:

rmmod b43 b43legacy ssb bcm43xx brcm80211 brcmfmac brcmsmac bcma wl
modprobe wl

or just reboot the system.

Any ideas on what I can do to resolve this and get my Broadcom network adapter working?
Is the broadcom-wl-dkms module the correct one I should be using?

Where did you get that 23 version from, the official stable repo has the 11 version that’s why it is trying to downgrade it.
I would suggest to start with removing that package first before trying to install it from official repo.

These speak for themselfs, you don’t have linux414-headers and linux59-headers installed.

Huh. I’m not sure where I got that module, but it must have been in the beginning trying to figure out this issue.
Anyway - your suggestion worked and I’m up and running.
I uninstalled the module, then re-ran sudo pacman -S broadcom-wl-dkms to install the correct module, and then rebooted.
It works fine now.

It was a long journey for me to solve this issue. This forum post was what ultimately got me there.
I am running a multiboot Hackintosh (macOS, Windows 10, Manjaro), and so I needed to use this Broadcom adapter to get full functionality on macOS.
Thank you for your help with the last mile.
