I have a problem, I have no Ethernet cable and I want to bypass the need of using it to install the WLAN and Wi-Fi Ubuntu driver. I did find a similar question, but it is old and the answer is not exactly what I wanted. I want to install the driver from the Internet from OS X, and put it onto the USB.
Then I will boot to Ubuntu partition, and install the driver from the USB. Is there a way to do it? A possibility would also be to download it from Ubuntu on VirtualBox, which I officially intended to delete and move it to a partition, and then put it onto a USB $ lspci -nn grep 0280 02:00.0 Network controller 0280: Broadcom Corporation BCM4331 802.11a/b/g/n 14e4:4331 Probably the standard MAC controller?
I have an MBP 13-inch mid 2012 UPDATE: Decided to download from a.deb package. On the site it says (located ), that the firmware installer supports 4331.

When i try to install it, it says: BCM4331 not supported. And in the software center, it says: Supported Chipsets: BCM4306/3 BCM4311 BCM4318 BCM4321 BCM4322 (only 14e4:432b) UPDATE: I also tried a Broadcom patch to support, though it has no effect. The b43 driver in /lib/firmware didn't load, though i'm going to ask a separate question on that. UPDATE: I found out why the B43 didn't load. Right at boot, before the login screen, this shows up in white text: 14.674744 irq 17: nobody cared (try booting withe the 'irqpoll' option) 14.674801 handlers: 14.674809 sdhciirq sdhci 14.674810 Disabling IRQ #17 14.717124 b43-phy0 ERROR: Firmware file 'b43/ucode29mimo.fw' not found 14.717125 b43-phy0 ERROR: Firmware file 'b43-open/ucode29mimo.fw not found 14.717126 b43-phy0 ERROR: Youmust go to and download the correct version. Please carefully read all instructions on this website What does this mean and how do I fix this? From other computer which has internet connection, or by using wired connection, do the following steps (copy to mbp and do make-make install): wget tar xjf b43-fwcutter-018.tar.bz cd b43-fwcutter-018 make sudo make install cd.
For Linux kernel 3.2 and newer we need to download and install version 5.100.138 of Broadcom’s proprietary driver (also from other computer which has internet connection and install it in mbp): wget tar xjf broadcom-wl-5.100.138.tar.bz2 sudo b43-fwcutter -w “lib/firmware” broadcom-wl-5.100.138/linux/wlapsta.o (do it in mbp) The next step is to activate/deactivate one of wireless drivers because we have more than one. To deactivate, sudo modprobe -r b43 bcma sudo modprobe -r wl And to activate, sudo modprobe b43 sudo modprobe wl.
The most simple method to install broadcom b43 wireless driver in LMDE. The most simple method to install broadcom b43 wireless driver in LMDE. This method applies to kernels 3.5 and above and depends upon replacing Debian firmware-linux-nonfree with Ubuntu linux-firmware-nonfree_1.14_all.deb. Follow these steps. The open drivers from the Open Firmware for WiFi (OpenFWWF) project are meanwhile still based on the initval data from Broadcom's firmware. Users extract this data by following the b43 driver installation process. The OpenFWWF project firmware is available for download from the University of Brescia (Italy) website. A few caveats: unsupported.

Hi everyone = I installed Ubuntu 18.04 on an old MacBook Pro 7,1 (Intel Core 2 Duo, 2010) and I don't have a Mac OS to return to (single boot =). Wifi hardware was not detected and after a lot of work, I was able to install it, chasing down all the dependencies. The two things I installed at first (along with dependencies, of course) were: bcmwl-kernel-source dkms So now the Wifi hardware is there, but it doesn't see any networks. Today, trying to solve this problem, I also installed this b43-fwcutter My Broadcom is 4322 (pci.id is 14e4:432b) I know a lot of people with Macs and Broadcoms have these problems, and I read through a lot of them. Still, I post this because I see that the problems and the solutions often turn out to be too specific in one way or another. Right now I don't remember everything I tried to fix this problem, but I guess the most important instructions (that led me to install those three things) are I appreciate your time and attention, thank you = EDIT: let me add that if I press and hold alt/option while booting, I get to this pre booting screen where WiFi works normally.
It's a long time since I fought with a Broadcom card but I remember the firmware loading was recorded in dmesg or syslog somewhere. Broadcom are generally tough to set up, and you're smothered in Windows software and stuff that doesn't work. Somebody cleaned old firmware out of the kernel in one of the many revisions. You may get better firmware from an old kernel. Then don't leave it to network manager, but try by hand. You have encountered wpapassphrase, have you?
Read the man page. Check with 1. Lapci / lsusb can you see it (module and firmware okay) 2.
Ubuntu For Mac Download
Iwlist wlan0 scan - can you see network(s)? Dhcpcd/dhclient Can you join one? This checks your config.
If you can't join try an open network such as a phone WiFi hotspot. Post your results. Thank you for responding = 1. Lspci gives Network controller: Broadcom Limited BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01) 2. Iwlist wlan0 scan gives wlan0 Interface doesn't support scanning 3.
Dhcpd command was not found (dhcpd5 not installed). Dhclient gives RTNETLINK answers: Operation not permitted Also, I forgot to mention that I tried to install Linux® STA 64-bit driver (released in 2015, downloaded from Broadcom website, hybrid-v3564-nodebug-pcoem-630223271.tar.gz) but couldn't. Also, how do I check dmesg or syslog for firmware loading? A couple of years ago I got a Broadcom chip in an HP laptop (vintage 2008) to work with Linux Mint 17.3 Cinnamon (based on Ubuntu 16.04 LTS). This link was helpful then.
At one point in the above link it states, 'Also, in Ubuntu System Settings-Hardware, there is an 'Additional Drivers' item. In the past, I have used that to obtain Broadcom drivers for my Dell Mini 9 netbook.' Using the Administration - additional drivers item in Linux Mint 17.3 did the trick for me. If Ubuntu 18.04 still has that item, it may work for you too. If not, maybe Ubuntu 16.04 might work.

Just a note that Mint 17.3 was based on Ubuntu 14.04, not 16.04.
