# Broadcom BCM4360 on Linux

    Linux: Manjaro

    Kernel: 6.3.5

    Card: Broadcom BCM4360 (14e4:43a0)

    Driver: WL

    

The only driver(1) that works for these boards is the **WL** driver (aka broadcom-wl, broadcom-sta), but it has the problem, at least in my case, of presenting a very unstable connection. To solve this, the possibility of working with a 40Mhz bandwidth in the 2.4Ghz band is disabled (2).

## Driver installation:

    # pacman -S linux63-broadcom-wl (recommended for the kernel version I have installed)

    or

    # pacman -S broadcom-wl-dkms (doesn't work as well with the other previous case)

Check if the configuration file is created that blacklists the modules in conflict with this driver. Otherwise, create a file in /etc/modprobe.d/broadcom-wl.conf with the following content:

    blacklist b43

    blacklist b43legacy

    blacklist ssb

    blacklist bcm43xx

    blacklist brcm80211

    blacklist brcmfmac

    blacklist brcmsmac

    blacklist bcma

    

## Disable 40mhz bandwidth on the 2.4ghz band

Create the module configuration file in /etc/modprobe.d/cfg80211.conf , with the content:

    options cfg80211 cfg80211_disable_40mhz_24ghz=Y

    

Save file and reboot the computer

This works for me and I hope it works for you too!!!
