2、基于上面的输出，在http://linuxwireless.org/en/users/Devices/USB 查询Driver的信息。

3. 安装必须要的软件：

$ yum install gcc automake autoconf kernel-headers kernel-devel -y

4. 下载compat-wireless-3.3-1.tar.bz2包，下载地址 http://linuxwireless.org/en/users/Download/stable/.

Since the current server does not have internet connection, I will need to download the driver into my local PC and transfer to the server using USB hard drive. I then copy the package into/root directory in the destination server.

5、减压并编译

$ cd /root
$ tar -xjzf compat-wireless-3.3-1.tar.bz2
$ cd compat-wireless-*
$ ./scripts/driver-select ath9k_htc
$ make
$ make install

$ cd /lib/firmware
$ wget http://linuxwireless.org/download/htc_fw/1.3/htc_7010.fw

$ init 6
