15

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 3 '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 6 '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

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.

    I had to also blacklist b43 and bcma which I suspect were being loaded for bluetooth functionality. – ctrlc-root Nov 13 '15 at 21:08
  • This worked for me and was pretty easy. Trying to install from apt repo as mentioned above didnt work for me. – guru_florida Apr 25 '17 at 4:10
  • I couldn't find the driver for this particular adapter on that site. Can you assist me on how to find the download? – Javis Jun 21 '18 at 13:06
  • Why do you choose wl over b43 – hello moto Oct 12 '18 at 9:55

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.
