I will outline the usual process to compile the files. This may or may not compile on your 3.19-xx kernel. If not, post the errors and I will propose another solution.
First, remove the device. Next, in the terminal, with a temporary internet connection by ethernet, tethered or whatever means possible:
sudo apt-get update && sudo apt-get -y upgrade
sudo apt-get install linux-headers-generic build-essential
Next, navigate to the location of the Makefile; in my case:
cd ~/Downloads/DPA_MT7601U_LinuxAP_3.0.0.1_20130802/DPA_MT7601U_LinuxAP_3.0.0.1_20130802
Now let's try a trial compilation:
make
If there are errors, please post them here and we'll attempt to fix them. If there are no errors (warnings may be OK), then install:
sudo make install
Insert the device. Is your wireless now working?
EDIT: Since we know now that the driver files included with your device will not compile in kernel version 3.19-xx, please try:
sudo apt-get install git
git clone https://github.com/art567/mt7601usta.git
cd mt7601/src
make
sudo make install
sudo mkdir -p /etc/Wireless/RT2870STA/
sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
sudo modprobe mt7601Usta
Please post any errors as before.
You have compiled the driver for your current kernel version only. When Update Manager offers a later kernel version, known as linux-image, after the requested reboot, recompile:
cd mt7601/src
make clean
make
sudo make install
sudo modprobe mt7601Usta
Please retain the file and these instructions for that time.
