There are several topics about similar mac/broadcom wifi cards, see if something helps. Probably the b43 firmware would be the first to test, or broadcom-wl
I just installed Manjaro on my 2011 MacBook Pro and my wi fi is not working. Its a Broadcom 4331. Previously worked under Fedora 35 and Mint 20. I believe I need the driver or pkg “firmware-b43-installer.”
I finally figure Pacman is what you use vice apt to install. Then I find out about yacourt and yay.
How do I add a repository or can I download the package and use Pacman to install?
Yes I am old and dumb and wasted two days looking on the net for an answer. Yeah I realize this duplicate…
I haven’t installed Manjaro yet. I only booted it up via a bootable USB. Everything seems to be working fine but not my wifi… I found out that my wifi card is Broadcom BCM43xx 1.0 (7.77.111.1 AirPortDriverBrcmNIC-1710.3)
I’m not sure what to do from here. I don’t wanna install it until I can get the wifi to work in bootable mode.
The broadcom chips in the Macbooks can usually be made to work with a number of drivers. Your BMC4331 chip-ID 14e4:4331 is compatible with b43 en:users:drivers:b43 [Linux Wireless] .
A good fallback kernel is 5.10LTS, expected EOL end of 2026, which works fine in my mbp 5,4 with BCM4322 (using the b43 driver). Since the current issue seems to be kernel-related just switching to 5.10 might already fix your problem. If it doesn’t you can switch drivers:
remove broadcom-wl-dkms
install b43-firmw…
Finally, after trying various Linux-distributions that did not run on this MacBook (Ubuntu, Linux Mint an Fedora) Manjaro did the trick. However, the WiFi-adapter is not found. These are the network adapters (wired internet works just fine):
Network:
Device-1: Broadcom NetXtreme BCM57765 Gigabit Ethernet PCIe driver: tg3
