I installed Ubuntu Trusty Tahr 14.04 LTS on a Lenovo Yoga 2 11 and noticed I had no wi-fi option, only networking (usually I see "enable wi-fi" too.)

rfkill list all resulted in only a soft block and after running sudo modprobe -r ideapad-laptop the soft block was removed.

The trouble is that I don't know were to go from here as I still do not have wifi. All of tutorials/docs I have found address what to do if you have a hard block.

If you have a wired connection and uname -r shows that you are using a 3.13 kernel you just need to sudo apt-get install bcmwl-kernel-source and reboot. If uname -r shows that you are using a 3.16 kernel, then you need to go http://packages.ubuntu.com/utopic/bcmwl-kernel-source to download it

I ended up fixing the problem by manually downloading bcmwl-kernel-source and its dependency dkms on another computer. I transfered the packages via usb and after I installed them using sudo dpkg -i I was able to access the internet just fine.
