I OWE YOU A BEER TOO!!

Sniffing around the net today many people are having this issue. Seems like a bit of a nightmare impacting Dell / Lenovo / Macbook and all the other Broadcom laptops.

Thanks

Thank you very, very much Chili555. I spent 2 days trying to explain to myself what happened with the wireless card in my HP ProBook 6360b and finally reached your post which solved this damned problem
Thanks a lot again.

You are very welcome! Thanks for the kind words and the beers. I'm glad it's working.

P.S: for noobs like me, also works on eMachines e525

Hi,

I only registered to say that I found this thread via Google and it seems to work.

You are the man, many thanks!

Hello all,

It doesn't work for me. After I install linux-header-generic , then "sudo apt-get install --reinstall bcmwl-kernel-source" . I still get error :
Running module version sanity check.
- Original module
- No original module exists within this kernel
- Installation
- Installing to /lib/modules/3.5.0-27-generic/updates/dkms/


depmod....

Do you have linux-backports-modules-cw installed?

sudo dpkg -s linux-backports-modules-cw-3.6-quantal-generic

If it is installed, remove it and try again:

sudo apt-get remove --purge linux-backports-modules-cw-3.6-quantal-generic
sudo apt-get remove --purge linux-backports-modules-cw-3.6-`uname -r`

Those tickmarks are on the left side of my US keyboard on the same key with ~.

sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl

Feel that little itch right there? That's known as a bug! You lucky Ubuntu person!

Ideally, if the kernel source were not installed, apt would...do what?...install it! Let's help it along:

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source
sudo modprobe wl
iwconfig

Now do we have wireless?

Excelente! Me anduvo a la perfección! Gracias!!

sudo apt-get install linux-headers-generic
sudo apt-get install --reinstall bcmwl-kernel-source

Re-installing following these guidelines helped me out as well after experiencing a similar problem after upgrading to UBUNTO 13.04.

Cheers!
