MacBook Pro (2011) "No WiFi Adapter Found"

Support Network
1

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
    v: kernel pcie: speed: 2.5 GT/s lanes: 1 port: N/A bus-ID: 02:00.0
    chip-ID: 14e4:16b4
  IF: enp2s0f0 state: up speed: 1000 Mbps duplex: full mac: <filter>
  Device-2: Broadcom BCM4331 802.11a/b/g/n driver: N/A pcie: speed: 2.5 GT/s
    lanes: 1 bus-ID: 03:00.0 chip-ID: 14e4:4331

I installed the broadcom-wl-dkms package, that I hoped would solve these issues (according to …some… other source). But still no luck. Thanks for any help resolving this, and thanks for making a distribution that works (so far) on an old MacBook. I’ve tried a couple of other distros that didn’t work.

First install the b43-firmware package from the AUR, then reboot, this should get it to work even without the dkms pkg you installed.

Also see 2009 macbook pro install fail - #4 by cscs and the linked B43 driver seems to be installed, but no place to check "enable wifi" in new install? - #43 by 6x12 or check other threads about Mac’s broadcom issues:
Search results for 'b43 @6x12' - Manjaro Linux Forum

please post the full output of the mandatory

inxi --admin --verbosity=7 --filter --no-host --width

without knowing what model etc… it’s just digging in the dark

Thanks for the help. I tried installing the package using the instructions here:
(can’t include links in my posts, it says, reformatting a bit)
wiki. manjaro. org/ index.php / Arch_User_Repository

This is what I get:

pamac search -a b43-firmware                                                                                ✔  12s 

Here is the output:

You need to enable AUR support in pamac-manager GUI first:
Open “Add/Remove software” >> click the 3 dots >> pick ‘Preferences’ >> pick ‘Third Party’ tab >> Enable AUR support.

Then open “Add/Remove software”, search for b43-firmware, hit install.

Sorry for not reading everything beforehand. I’m getting tired of this trying-to-run-linux-on-a-mac. I think I’ve been trying this for about 10-12 hours now.

I got this working now. I had to uninstall the broadcom-wl-dkms-package (can’t remember exactly why I installed it in the first place) to make it work.

Thanks for the help. This MacBook seems to work like a charm running Manjaro now.
