我这次是在

WIFI on BeagleBone：

Steps

1. Get a binary of the Realtek drivers
2. Install the driver
3. Configure your WIFI settings

1) Build the RTL8192 Driver

Note: You can get the pre-patched source code here and a pre-built binary of the driver here.  These may or may not work though, so I would recommend building it yourself.

1. Download the Unix/Linux driver from the Realtek web site - It will be called something like RTL8192xC_USB_linux_v3.4.4_4749.20121105.zip
2. Unzip the file and then unpack the driver source which is  driver/tl8188C_8192C_usb_linux_v3.4.4_4749.20121105.tar.gz in the zip file

   cp rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105.tar.gz ~/
   tar xvfz rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105.tar.gz
   cd rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105

3. Download this patch to add BB config and to fix building on linux 3.8 into the driver directory and apply it

   wget https://raw.github.com/cmicali/rtl8192cu_beaglebone/master/util/rtl-8192-beaglebone-linux-3.8.patch
   patch -p1 < rtl-8192-beaglebone-linux-3.8.patch
   

4. Build the driver - Replace your_kernel_dir with the root of your BeagleBone 3.8 kernel source (mine is ~/projects/beaglebone_kernel/kernel)

   make KSRC=your_kernel_dir
   

***注意：3处的patch必须做，4处的KSRC是当前所在源码的绝对路径，当编译模块.ko文件时make KSRC=~/source-kernel/，当要编译进内核镜像，则可以把KSRC=~/source-kernel修改进rtl8192cu目录下的makefile里面。

2) Install the RTL8192 Driver

    此处直接在目标板上insmod 8192cu.ko或者下载镜像即可

3) Configure your Access Point

1. Edit /var/lib/connman/settings and enable WIFI

   [global]
   OfflineMode=false
   
   [Wired]
   Enable=true
   Tethering=false
   
   [WiFi]
   Enable=true
   Tethering=false

2. Encrypt your passphrase

   wpa_passphrase YourSSID YourPassphrase

3. Edit /var/lib/connman/wifi.config and set it to the following

   [service_home]
   Type=wifi
   Name=YourSSID
   Passphrase=YourEncryptedPassphrase

4. Plug in your WIFI adaptor and reboot

   shutdown -r 0

之后插上usb wifi之后，就会自动获取ip，上网
