eBay wifi module for RaspberryPi buy and setup

Last month I bought a wifi Module for my RaspberryPi 2 and it's so small. But it was not working as it is! So doing so research and I found some solution is working for me. It's so cheap and small.
eBay link:
http://www.ebay.com/itm/231273301300?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

And the solution is:

sudo apt-get install linux-headers-generic build-essential git
sudo apt-get install git
git clone https://github.com/porjo/mt7601.git 
cd mt7601/src
make
sudo make install
sudo mkdir -p /etc/Wireless/RT2870STA/
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
sudo modprobe mt7601Usta

For Windows: http://www.mediatek.com/en/downloads/ and look for "mt7601"

Let me know if you got success! Have a nice day!
