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:
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
I know this question is pretty old, but here's what worked for me:
tar xvf <filename>
.sudo modprobe -r wl
.sudo apt-get remove bcmwl-kernel-source
.make && sudo make install
.sudo modprobe wl
.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:
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.
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: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:If it's already installed you can use the following to enroll a new MOK:
After a reboot the adapter is working again.
