How do I install `bcmwl-kernel-source` with dpkg
As we see, bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4 doesn't compile correctly for your system. On my system, using the exact same kernel version, bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7 installs correctly. I therefore suggest:
mkdir bcmwl && cd bcmwl
wget http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7_amd64.deb
sudo dpkg -i bcmwl*.deb
Is there any improvement?
