Install 360 Wifi2 (MT7601U) driver in Ubuntu

真是很抱歉，我忘记是在什么地方看到的这个方法了，总之是感谢这大神的回复了。 原述如下，真的很简单，而且很管用！

I suggest you get a temporary internet connection, ethernet, tethered or whatever is available. Then do:

1 $ sudo apt-get install linux-headers-generic build-essential git
2 $ sudo apt-get install git
3 $ git clone https://github.com/porjo/mt7601.git
4 $ cd mt7601/src
5 $ make
6 $ sudo make install
7 $ sudo mkdir -p /etc/Wireless/RT2870STA/
8 $ sudo cp RT2870STA.dat /etc/Wireless/RT2870STA/
9 $ sudo modprobe mt7601Usta

Your wireless should now be working.

首先用网线临时连上网络吧，然后在终端中运行上面语句，Wifi应该就可以工作了。

但是，如果今后Ubuntu升级了linux kernel，那么你还需要重新编译，运行以下代码即可。

You have compiled the driver for your current kernel version only. When Update Manager installs a later linux-image, after the required reboot, you must re-compile:

1 $ cd mt7601/src
2 $ make clean
3 $ make
4 $ sudo make install
5 $ sudo modprobe mt7601Usta

好了，可以好好用Wifi啦！
