I've seen many other posts like this and found one other where the problem was resolved, but the terminal commands given were for a different pcid than mine. I ran several commands including:

sudo apt-get install linux-headers-generic

which got the response:

linux-headers-generic is already the newest version.

I also ran:

sudo apt-get install --reinstall bmcwl-kernel-source

Which got the error message:

E: unable to locate package bmcwl-kernel-source

I am new to Linux, but this seems to be a pretty common issue with 12.10. My pcid is 14e4:4331

If anyone could help, I would really appreciate it.

You typed:

sudo apt-get install --reinstall bmcwl-kernel-source

It is not bmcwl, it is bcmwl:

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