怎样在bt4下使用tp-link 722n网卡（虚拟机可用，但不是很稳定）
本帖最后由 ggmk5 于 2010-5-27 15:39 编辑经过一个多月的反复试验 终于在bt4下成功运行tp 722n网卡 现跟大家分享一下经验
简要步骤跟大家说一下
1.从http://files.iniza.org/ath9k_htc/compat-wireless-2010-03-19_with-ath9k_htc-support.tar.bz2下载驱动包
2.从http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=blob_plain;f=ar9271.fw;hb=35b308409dc18991ec833c这里下载ar9271.fw文件
3.把驱动包和fw文件放到bt4的任意目录下（本人放在/root/d目录下）
root@bt:~/d# cd /root/d/
root@bt:~/d# ls
ar9271.fw
compat-wireless-2010-03-19_with-ath9k_htc-support.tar.tar
4.解压驱动包，然后进入解压的目录
root@bt:~/d# tar xf ompat-wireless-2010-03-19_with-ath9k_htc-support.tar.tar
root@bt:~/d# ls
ar9271.fw
compat-wireless-2010-03-19
compat-wireless-2010-03-19_with-ath9k_htc-support.tar.tar
root@bt:~/d# cd compat-wireless-2010-03-19
root@bt:~/d/compat-wireless-2010-03-19#
5.然后编译驱动
root@bt:~/d/compat-wireless-2010-03-19#make
root@bt:~/d/compat-wireless-2010-03-19#make install
6.编译完成后把ar9271.fw文件复制到/lib/firmware目录下（切记！！！！）
root@bt:~/d/compat-wireless-2010-03-19#cd ..
root@bt:~/d#cp -r ar9271.fw /lib/firmware
（千万记住/lib目录下的firmware目录一定不能是连接符号！！。bt4默认的/lib/firmware目录是
lrwxrwxrwx1 root root 17 Apr 22 10:03 firmware-2.6.30.9 -> firmware-2.6.30.9这点切记
可以用下列命令即可
rm -rf firmware
cp -r firmware-2.6.30.9 firmware）
7.然后运行下列命令，如果显示如下说明你已经成功了！！
root@bt:~/d# modprobe -l | grep ath9k_htc
/lib/modules/2.6.34-rc5/updates/drivers/net/wireless/ath/ath9k/ath9k_htc.ko
8。下面是心动的一刻
root@bt:~# lsusb

9.下面是心动之旅
root@bt:~# airmon-ng start wlan0
