Ubuntu – How to install Broadcom Wireless Adapter BCM4352 802.11ac PCID [14e4:43b1] (rev 03) on fresh install of Ubuntu 14.10 (Utopic Unicorn)


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?


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
