I am not able to install drivers for my Wi-Fi + Bluetooth card (Broadcom BCM43142).
What I have done till now:
- I have tried using the drivers at this website.
- I tried following the instructions given here for both the
apt-get
install, download tar ball and install and offline install (from Ubuntu's boot DVD). - I tried installing
bcmwl-kernel-source
.
At the end of every single method [1,2,3], when I do a sudo modprobe wl
, I invariably get this:
modprobe: ERROR: could not insert 'wl': Exec format error.
I have also tried blacklisting drivers other than wl
and have tried reinstalling the same several times.
- I also tried using
ndiswrapper
which was successful enough to make the UNCLAIMED driver (see below for the output oflshw -c Network
) change to something else.
However at the end the Wi-Fi did now show up or work.
Kernel version: 3.13.0-24-generic
I have tried everything I could do to my full ability. It would be extremely helpful if you could help me setup my Wi-Fi. I am willing to pastebin output of any commands that you might ask me to execute. (I have added the outputs of lshw -c Network
and lspci -nn
, but please don't hesitate to ask me anything else.)
lshw -c Network

Also, what is meant by the same?
I went through the following Ask Ubuntu questions:
The second one seems to be a very comprehensive summary of all possible ways... Still I am stuck up with this Exec Format error
.
modprobe wl
that I previously mentioned. I meant this jas.gemnetworks.com link. Does it work for you ?
