Linux安装TP-Link TL-WN722N 驱动


TL-WN722N的芯片是AR9271，驱动型号是 ath9k_htc

下面是在Linux下安装过程：

01 root@bkjia www.bkjia.com:~# lsusb

26 root@bkjia www.bkjia.com:~/ar9271# reboot

重启后，用 iwconfig  就能看到 wlan0 了。


值得一提的问题：
如果重启后看不到 wlan0 ，用 dmesg | grep -e ath -e wlan 看下是不是有错误。
usb 1-1: ath9k_htc: Firmware – ar9271.fw not found
如果是这个not found错误，那说明你没有把 ar9271.fw 拷贝到 /lib/firmware 下面。

ar9271.fw 可以直接到这里下载，不过只能通过raw 下载，否则下载的文件大小都是0字节的。用 raw 连接下载需要更改文件名。

还有一种安全一点办法就是上面用到的 git 命令，把所有的 fw 都下下来，这样就不用当心下载错什么问题，就是用的时间稍长些。

虚拟机上的问题：
root@bkjia www.bkjia.com:~# dmesg | grep -e ath -e wlan
md: multipath personality registered for level -4
usb 1-1: ath9k_htc: Firmware – ar9271.fw download failed
ath9k_hif_usb: probe of 1-1:1.0 failed with error -22
usbcore: registered new interface driver ath9k_hif_usb
搜索到的全是驱动源文件，试试没有安装 VMTools 的

BT4 R1能直接识别出是 Atheros Communications, Inc. AR9271 802.11n ，如果是BT4 ，只能识别出是 Atheros Communications 。
