I have a brand new Dell XPS 15. I dual boot it with Windows 8.1 and Ubuntu 14.10 The Wireless Network Adapter is Broadcom BCM4352 802.11ac with PCID [14e4:43b1] (rev 03).

The 4352 is not included in the list for installation via bcmwl-kernal-source file. I tried this anyway, but the Terminal command led to the file starting to install, but then stopping. Sometimes I get a permission denied error message.

As a result of reading and trying all advice from forums I have decided to completely reinstall Ubuntu 14.10. I doubt my particular Broadcom Wireless Card has no support on Ubuntu 14.10?

Edit:

The advice of Chili555 worked. I now have working wifi using Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03)

The 14e4:43b1 device isn't yet included on the many guides because we're not quite sure how to get it working yet. We are happy you've volunteered to help us!

The most likely driver is bcmwl-kernel-source. Let's try again:

sudo apt-get update
sudo apt-get install bcmwl-kernel-source
sudo modprobe wl

If you haven't any other network connection available, you may follow this process to get the files from the install USB: Unable to connect to any Wifi in Ubuntu 14.04

    Just wanted to confirm that I have a Lenovo y50-70 using Broadcom BCM4352, 14e4:43b1 (rev 03) and this driver worked. Thanks! – wmjbyatt Apr 03 '15 at 17:13
  • I also have Lenovo y50 with BCM4352 802.11ac and this driver worked. Many thanks! – Stev Jun 16 '15 at 14:23
  • This worked for me to get wifi working on a Dell Precision M3800. Thanks :) – juckele Mar 15 '16 at 17:21
  • This also worked for the Asus G750J. Thx :) – Marco Feb 06 '17 at 19:23
  • To add to this, it seems that on Ubuntu 18 the bcma and/or b43 will load even if blacklisted with modprobe -b. If you reboot and your stops working, do modprobe -r bcma && modprobe -r b43 && modprobe -r wl && modprobe wl and it should work again. – jamzsabb May 25 '18 at 17:41
  • On Lenovo Yoga 2 (with Broadcom BCM4352) this driver works, but the connection with internet drops from time to time and can get very annoying. – Javis Jun 21 '18 at 13:02
  • @Javis I recommend that you start your own new question. – chili555 Jun 21 '18 at 13:51

I'm on 18.04.2 Cinnamon 4.0.6, Thinkpad T420 BCM4352. This thread still appears relevant since some people like me have old hardware.

I installed via:

#  apt install broadcom-sta-dkms

Watched it build the firmware into initrd file in /boot partition, rebooted, and voila. WiFi active, was able to join an SSID listed in Network-Manager right away.

Couldn't have been easier.

I know this question is pretty old, but here's what worked for me:

  1. Download the current STA driver from Broadcom's website at http://www.broadcom.com/support/?gid=1. Create a new folder and move the downloaded file into it, then cd into the folder. Expannd with tar xvf <filename>.
  2. Unload the current STA driver by running sudo modprobe -r wl.
  3. Remove the current driver's package with sudo apt-get remove bcmwl-kernel-source.
  4. Install the new driver by running make && sudo make install.
  5. Load the new driver with sudo modprobe wl.

Had the same problem with Ubuntu 18.04 on Dell XPS 13 9343, where the wireless adapter recently stopped working after an upgrade. The proprietary driver (bcmwl-kernel-source, which is the only one that supports BCM4352 802.11ac) would not load:

$ sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
$ sudo modprobe wl
modprobe: ERROR: could not insert 'wl': Required key not available

As it turned out, you need to switch off Secure Boot in order to activate this (updated) driver. The easiest way to do that is installing shim-signed and following the required steps:

sudo apt install shim-signed

If it's already installed you can use the following to enroll a new MOK:

sudo update-secureboot-policy --new-key

After a reboot the adapter is working again.

  • You should be able to disable secure boot in the bios menu. – Jason C May 26 '19 at 16:16

    Thanks for the hint; this set me on a similar track. When I installed bcmwl-kernel-source (from the Additional Drivers tool on 20.04), it was prompting me to set a UEFI password. However, I didn't realise that I had to explicitly choose "Enrol MOK" on the UEFI boot screen that showed on restart so that I could enter that password so that the driver would be loaded correctly. – Harry Cutts Mar 14 '21 at 23:17
  • @HarryCutts You should make your comment in to an answer because I didn't know about the Additional Drivers tool and that's what got my BCM94352HMB Wifi Card working on Ubuntu mate 20.04. Then this advice got my Bluetooth working. – FlexMcMurphy Jun 06 '21 at 11:45
