Yoga 2 13 wifi not working

Question

Hi,
I have recently installed Ubuntu 14.04 on my Yoga 2 (not pro). Wifi won't work on Ubuntu and I don't understand how people made it work (I don't know much about Linux). Would you help me understand that :
(1) Download the kernel source
$ sudo apt-get install build-essential linux-headers-$(uname -r)
$ cd ~/workspace
$ git clone git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git
$ cp ~/workspace/ubuntu-trusty/drivers/platform/x86/ideapad-laptop.c ~/workspace/ideapad/
$ cd ~/workspace/ideapad/
(2) Change the function ideapad_rfk_set(void *data, bool blocked) in ideapad-laptop.c to
static int ideapad_rfk_set(void *data, bool blocked)
struct ideapad_rfk_priv *priv = data;
/* hack to unblock wireless by sending 1 to these bits */
write_ec_cmd(priv->priv->adev->handle, VPCCMD_W_RF, 1);
write_ec_cmd(priv->priv->adev->handle, VPCCMD_W_BT, 1);
write_ec_cmd(priv->priv->adev->handle, VPCCMD_W_WIFI, 1);
return 0;
return write_ec_cmd(priv->priv->adev->handle, priv->dev, !blocked);
(3) Create a file named Makefile:
obj-m += ideapad-laptop.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
(4) Build the new module
$ cd ~/workspace/ideapad/
$ make
(5) Load the module
$ cp /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko ~/ideapad-laptop.ko.backup
$ sudo cp ~/workspace/ideapad/ideapad-laptop.ko /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/
$ sudo modprobe -r ideapad-laptop
$ sudo modprobe ideapad-laptop
$ sudo rfkill unblock all
$ sudo modprobe -r ideapad-laptop
$ sudo mv ~/ideapad-laptop.ko.backup /lib/modules/3.13.0-24-generic/kernel/drivers/platform/x86/ideapad-laptop.ko
(6) Blacklist the ideapad module
$ cd /etc/modprobe.d/
$ sudo echo 'blacklist ideapad-laptop' > blacklist-ideapad.conf
(7) Reboot the Yoga 2 laptop
Am I supposed to write all this in the terminal ?
I tried it once and it failed at  step 3 because "shell" was not recognize. Then windows stopped working and I had to reinstall it.
I'm completely lost and I desperetly need the wifi to work on Linux.
Thanks for your help

If it's a hardware problem, all you have to do is order a Intel Centrino 7260 Advanced-N or Advanced-AC. Below is an example of the WLAN card you may want to buy.

You may need a TX3/4/5 screw driver to remove the bottom base cover and a cross screw driver to remove the WLAN card.
Can't remember exactly which number. But you will save a lot of money in the end.
