2016年9月1日更新：最新的raspbian（jessie）系统已经原生支持小度wifi

——————————————————————————————————

一、材料准备

1、raspberry pi 2代

2、小度wifi

二、操作步骤

1、在raspberry pi上安装raspbian系统。

官方镜像下载地址：https://www.raspberrypi.org/downloads/

备用地址：http://pan.baidu.com/s/1ntkTzpn

2、安装gcc4.8

参考文章：https://somewideopenspace.wordpress.com/2014/02/28/gcc-4-8-on-raspberry-pi-wheezy/

1）添加软件源：

sudo nano /etc/apt/sources.list

在sources.list中添加以下内容

deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb http://archive.raspbian.org/raspbian wheezy main contrib non-free rpi
# Source repository to add
deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free rpi
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
deb http://archive.raspbian.org/raspbian jessie main contrib non-free rpi
# Source repository to add
deb-src http://archive.raspbian.org/raspbian jessie main contrib non-free rpi

2）新建preferences文件

sudo nano /etc/apt/preferences

添加以下内容

Package: *
Pin: release n=wheezy
Pin-Priority: 900
Package: *
Pin: release n=jessie
Pin-Priority: 300
Package: *
Pin: release o=Raspbian
Pin-Priority: -10

3）更新软件包

sudo apt-get update

4）Install gcc/g++ 4.8 from jessie repositories

sudo apt-get install -t jessie gcc-4.8 g++-4.8

5）Install alternatives

sudo update-alternatives --remove-all gcc
sudo update-alternatives --remove-all g++

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 20
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 50
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.6 20
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 50

3、用rpi-source软件准备内核编译环境

参考文章：https://github.com/notro/rpi-source/wiki

1）下载rpi-source软件

sudo wget https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source -O /usr/bin/rpi-source && sudo chmod +x /usr/bin/rpi-source && /usr/bin/rpi-source -q --tag-update

备份地址：http://pan.baidu.com/s/1i3w6Mkl

2）运行rpi-source

sudo rpi-source

4、编译小度wifi驱动

1）下载源码文件

官方驱动下载地址：http://www.mediatek.com/zh-CN/downloads/mt7601u-usb/

备份地址：http://pan.baidu.com/s/1i3s3a4H

2）修改源文件

tar xjvf DPO_MT7601U_LinuxSTA_3.0.0.4_20130913.tar.bz2

cd DPO_MT7601U_LinuxSTA_3.0.0.4_20130913/

打开 common/rtusb_dev_id.c，在 {USB_DEVICE(0x148f,0×7601)}, /* MT 6370 */ 下面加入以下内容：

{USB_DEVICE(0x148f,0x760b)}, /* 360 Wifi */

{USB_DEVICE(0x2955,0x1001)}, /* baidu Wifi */

{USB_DEVICE(0x2a5f,0x1000)}, /* Tencent WiFi */

{USB_DEVICE(0x2955,0x0001)}, /* XiaoDu Wifi */

{USB_DEVICE(0x2717,0x4106)}, /* Xiaomi Wifi */

打开 include/os/rt_linux.h，找到

int fsuid;

int fsgid;

并把它改为

kuid_t fsuid;

kgid_t fsgid;

3）编译安装

make

make install

modprobe mt7601Usta

5、修改配置文件

修改/etc/network/interfaces文件：

auto lo

iface lo inet loopback

iface eth0 inet dhcp

allow-hotplug wlan0

iface wlan0 inet manual

wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp

#allow-hotplug ra0

#iface ra0 inet manual

#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf

修改/etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

update_config=1

network={

ssid="yourssid"

psk="yourpassword"

proto=RSN

key_mgmt=WPA-PSK

pairwise=CCMP TKIP

group=CCMP TKIP

auth_alg=OPEN

priority=3

}

新建/etc/udev/rules.d/95-ralink.rules文件，将无线网卡ra0改为wlan0

nano /etc/udev/rules.d/95-ralink.rules

添加以下内容

ACTION=="add", SUBSYSTEM=="net", ATTR{type}=="1", KERNEL=="ra*", NAME="wlan0"

6、无线路由器模式
