My computer is not recognising the wireless network. When I try to activate my drivers I get errors. I tried to solve by:

sudo apt-get remove bcmwl-kernel-source
sudo apt-get install bcmwl-kernel-source

but I am getting these errors :

Building initial module for 3.8.0-30-generic
Error! Bad return status for module build on kernel: 3.8.0-30-generic (i686)
Consult /var/lib/dkms/bcmwl/6.20.155.1+bdcom/build/make.log for more information.
FATAL: Module wl not found.
update-initramfs: deferring update (trigger activated)
