try removing the ideapad_laptop module

for one time test:

sudo rmmod ideapad_laptop

for working after reboot:

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

I had the same issue, and solved for me. (The solution can also be found here:Wifi Not Working On Ubuntu 14.04 Lenovo G 50-30 )

The answer is:

sudo modprobe -r ideapad-laptop
sudo rfkill unblock all
rfkill list all

This problem has been fixed by me in Ubuntu kernel 3.19.0-26, that is now available for Ubuntu 14.04 and 15.04.

If you are affected by this issue, update the kernel by running

sudo apt-get install linux-generic-lts-vivid
