How to install RT2870/RT3070 Wireless Driver?

I have an alfa awus036h, but I don't know how to install the driver on ubuntu 14.04. When the device is plugged and wireless switch is off. This is is the output of lsusb.

I have a device that uses the same driver, just labelled ralink USB Wifi Dongle. This is what I did to get mine to work:

UPDATE: You may have to download kernel headers, if you don't have them already:

sudo apt-get install linux-headers-$(uname -r)

Plug the dongle in, and run the following lines in a terminal:

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

Afterwards, it picks up in the GUI network tool. A reboot may be required.

Hope that helps.

There's a ppa repo for this - MT7601 STA driver. I have tested it for RT2870 driver and it worked for me.

Plug your USB adapter in and run the following commands:

sudo add-apt-repository ppa:thopiekar/mt7601
sudo apt-get update
sudo apt-get install mt7601-sta-dkms

When the installation completes, click on the wi-fi network icon and you should see the USB adapter network interface.

Before proceeding onto @Hitsugaya198 solution you have to diable built-in wifi adapters as below.

Add the following line to /etc/network/interfaces:

iface wlan0 inet manual

NetworManager don't manage interfaces configured in the interfaces file. Replace wlan0 with the interface you want to disable, if it's not the name of the built-in interface.

Then restart network manager

sudo service network-manager restart

After the above steps, proceed with @Hitsugaya198 solution and that works perfectly.
