BCM4360 802.11ac Wireless Network Adapter not visible after upgrade

Asked by budrik

Hi
following wlan card seems not to be supported anymore by bcmwl-kernel-sources after a kernel upgrade (on a mac book pro retina 11.1)

***
lspci -vvnn | grep Network
03:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

***
uname -a
XXX XXX 3.13.0-55-generic #94-Ubuntu SMP Thu Jun 18 00:27:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

When re(installing) bcmwl-kernel-sources i get:

***
wl:
Running module version sanity check.
 - Original module
   - No original module exists within this kernel
 - Installation
   - Installing to /lib/modules/3.13.0-55-generic/updates/dkms/

depmod....

DKMS: install completed.
modprobe: ERROR: could not insert 'wl': Unknown symbol in module, or unknown parameter (see dmesg)

***
dpkg -l | grep -i bcmwl
ii bcmwl-kernel-source 6.30.223.248+bdcom-0ubuntu0.1 amd64 Broadcom 802.11 Linux STA wireless driver source
***

What was changed? Also by running a bootable USB, the wlan card is not detected - same issue!

It's on my working machine, help would be appreciated ;-)

Best Regards
Budrik

What did you upgrade from?
What is the output of:

lsb_release -a

What steps did you take to upgrade the OS?

Hi, normally I upgrade via muon-updater or occasionally by apt-get

lsb_release -a:

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty

I tested with bootable USB-sticks Ubuntu LTS and Kubuntu LTS with the same error. I guess it's a bug, but can't find anything.

Does anybody have the same experience?

Ok, I finally got it:

1) while installing bcmwl-kernel-sources, it failed with:

modprobe: ERROR: could not insert 'wl': Unknown symbol in module, or unknown parameter (see dmesg)

2) in "/var/lib/dkms/bcmwl/6.30.223.248+bdcom/3.13.0-57-generic/x86_64/log/make.log" I had a warning pointing me to the gcc-compiler (after 4 hours search!)

3) I purged bcmwl-kernel-sources and gcc-4.8

4) I reinstalled bcmwl-kernel-sources which pulled again gcc and it worked

Wifi works again ;-)
