No WiFi after installing Linux Mint on Macbook Air 2013 with BCM43224/5 Adapter

Post by litos2121 » Mon Jun 14, 2021 2:41 pm

New to Mint and been having problems connecting to Wifi. I’ve tried various solutions on here, but none of them seem to work. I’m currently working with an Ethernet connection, but would like to use WiFi. I’ve tried updating the driver manager, but nothing gets loaded. Here are a few command outputs that I’ve seen around. Let me know if there’s anything else I should run.

By default older Mac computer models have driver issues with the Broadcom Wi-Fi chip. Most instructions online (such as this one from the official Ubuntu docs @ https://help.ubuntu.com/community/Macmini5-1/Precise) suggest to use sudo apt-get and install these packages from the PPA.

BUT you don’t have Internet so you can’t use apt-get ! Instead you can use a different computer to download the packages, then transfer them over.

In the instructions below, you will need to replace sid in the download URL’s with the proper version of Debian your version of Ubuntu/Linux is using. To find which version you should use, you can view the chart at https://askubuntu.com/questions/445487/what-debian-version-are-the-different-ubuntu-versions-based-on#445496. If you’re using jessie for example, then replace all sid with jessie in the links below.

1. Download b43-fwcutter @ https://packages.debian.org/sid/b43-fwcutter (replace «sid» in the URL as needed — scroll down to «Download» section and choose based off your architecture, and then select a mirror/FTP link to download from on the next page that appears).
2. Download firmware-b43-installer @ https://packages.debian.org/sid/firmware-b43-installer (repeat same note as above)
3. Download webfs @ https://packages.debian.org/sid/webfs (repeat same note as above)
4. Download http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 (e.g. using wget http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 )
5. Save these downloaded files to flash storage and then insert flash storage into your Ubuntu/Linux machine.
6. Copy the files from the flash storage to your Ubuntu/Linux machine’s desktop.
7. Open a terminal and run the command echo ‘127.0.0.1 www.lwfinger.com’ | sudo tee —append /etc/hosts
8. Run the command sudo dpkg -i ~/Desktop/webfs.deb (replace webfs.deb with the webfs deb file name)
9. Run the command sudo mkdir -p /var/www/b43-firmware
10. Run the command sudo mv ~/Desktop/broadcom-wl-5.100.138.tar.bz2 /var/www/b43-firmware/
11. Run the command sudo sed -i -e ‘s/web_root=»\/var\/www\/html»/web_root=»\/var\/www»/’ /etc/webfsd.conf
12. Run the command sudo sed -i -e ‘s/web_port=»»/web_port=»80″/’ /etc/webfsd.conf
13. Restart the web server sudo /etc/init.d/webfs restart (you may need to use sudo systemctl restart webfs if your system uses systemd )
14. Run the command sudo dpkg -i ~/Desktop/b43-fwcutter.deb (replace b43-fwcutter.deb with the b43-fwcutter deb file name)
15. Run the command sudo dpkg -i ~/Desktop/firmware-b43-installer.deb (replace firmware-b43-installer.deb with the firmware-b43-installer deb file name)
16. Run the command echo ‘blacklist ndiswrapper’ | sudo tee —append /etc/modprobe.d/blacklist.conf
17. Run the command echo ‘SUSPEND_MODULES=»b43 bcma»‘ | sudo tee —append /etc/pm/config.d/modules
18. Run sudo reboot and then check if you can connect to Wi-Fi.
19. See https://help.ubuntu.com/community/MacBookPro8-2#Wireless for other instructions, such as enabling Sensors. Also see https://askubuntu.com/questions/334561/problems-with-broadcom-bcm4311-wireless-card-on-hp-pavillion-dv6000#667832 for reference.
20. Remove webfs and the temp dir by typing sudo apt-get remove -y webfs and sudo rm -rf /var/www/b43-firmware/ on your Ubuntu/Linux machine afterwards.

No working on macbook air
Did everything as u said
But not working on kali linux
nothing changes after restarting

this solution doesn’t work for me, I found another simpler solution to this problem. Just go to this page to download and install the driver, by the way, my mac mini is late 2014 and the OS is Debian 10 (buster).

I created a GitHub account just now for the express purpose of returning here to say: holy crap, it worked! thankyouthankyouthankyou

inherited my mom’s mid-2009 15″ MB Pro when she passed a few years ago. It’s still a super beefy rig (4g dual core half gig storage — very well suited for creative content production), excepting of course for the Cupertino Colossus’ insistence upon abandoning their own still-working hardware. I was determined to return it to a state of usefulness. Ubuntu was the obvious choice. I’d tried it several years ago and really liked it. (fwiw, non-tech me had ZERO problems setting it up as a dual-boot in the PC / Windows environment on a Dell I’d had at the time, although that ease probably had a lot to do with having had a cooperative CD burner at the time).

Again — I am not a super tech-savvy guy. Neither of our Apple «super drives» (hows THAT for cynical branding, btw?) work reliably (i.e. no burn-to-DVD), so the OS installation itself required my patience and LOTS of persistence.

And then I ran into the Broadcom / wifi issue . good times hahaha

more persistence applied . but even though my deep dive into a discomfort zone found me working through these steps VERY slowly / cautiously, at the culmination of the last step, first attempt, the clouds parted, a chorus of angels began singing, and blink! — wifi visible and functional.

Super relieved, and extremely grateful. I have what’s functionally a brand new decade old laptop. And it’s again a nimble screamer of a rig. Thank you again! -dave

Thank you so much for this

Thanks!
This worked for me.
One thing I had to do was run chmod -R 777 /var/www because I was getting a 403 access denied error at step 15. Probably would be better to allow just read access to the specific file that we moved there. Might be worth adding to the instructions if this is an issue a lot of people will run into.

I tried and when I get to the line where «. webfsd.conf. » (line 11 and 12), it does not work. This file does not exist in the \etc folder.

Thanks!

please do not ever use chmod 777 unless you absolutely know what you’re doing. You almost certainly could have simply done chmod -R +r /var/www (which grants read permissions recursively to everything under /var/www ) instead and not have compromised the security of your system.
