记录centos安装tp-link WN821N驱动

1、首先查询一下usb驱动的类型

$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub Bus 002 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub Bus 001 Device 003: ID 046d:c05b Logitech, Inc. Bus 001 Device 004: ID 413c:2107 Dell Computer Corp. Bus 001 Device 005: ID 0cf3:7015 Atheros Communications, Inc. TP-Link TL-WN821N v3 802.11n [Atheros AR7010+AR9287] Bus 002 Device 003: ID 18e3:9106 Fitipower Integrated Technology Inc

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

6、另外我们需要下载相对应的固件

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

$ init 6

7、restart机器
