I wiped Windows 8 upon buying my new lenovo G50-30 laptop. The wireless is turned off by hardware switch. I have used 

sudo rmmod ideapad_laptop

Which works, but I must re-enter the code everytime I turn on the computer. I also tried thi code I found in the forums to fix the problem more permanently

echo "blacklist ideapad_laptop" | sudo tee -a /etc/modprobe.d/blacklist-ideapad.conf

but is not working for me...nothing happens.

Code used was found at this link in the Ubuntu Help Forums

This is a known bug. Ideapad-laptop module blocks wifi on this module. A kernel quirk is needed. It is possible just blacklist ideapad-laptop module, but some other hardware may malfunction. I submitted a patch upstream to fix it. While it is applied and gets to Ubuntu, you can use ppa with the patched module. It can be installed by running

sudo add-apt-repository ppa:hanipouspilot/ideapad-laptop
sudo apt-get update
sudo apt-get install ideapad-laptop-dkms

Update For those who uses kernel 3.19 this ppa can be removed since 3.19.0-26 kernel includes this patch.
