TL-WN722N的芯片是AR9271,驱动型号是 ath9k_htc
下面是安装过程:

26 root@bt:~/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(我的opensuse显示的是htc_9271.fw not found,那就在下面的网址中找htc_9271.fw即可)
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(或htc_9271.fw) 的来源,可以直接到 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。
