acer(宏基) Aspire E1-472G ubuntu-12.04下安装无线网卡驱动

本人前阶段时间买了个比较实惠的笔记本电脑acer(宏基) Aspire E1-472G，自带linux操作系统，由于工作需要便把操作系统换成了ubuntu12.04，但一直苦于没有无线网卡驱动。今天终于把这个问题给解决了，方法如下：

1，查看无线网卡型号：

~$lspci -vnn | grep Wireless

我的无线网卡是：

02:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)

2.安装

linux-headers-generic

和

build-essential

~$sudo apt-get install linux-headers-generic build-essential

3.下载驱动文件并安装：

~$

sudo -i wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.9-rc4/compat-drivers-3.9-rc4-2-s.tar.bz2

~$

tar xvf compat-drivers-3.9-rc4-2-s.tar.bz2

~$

cd compat-drivers-3.9-rc4-2-s/

~$

./scripts/driver-select ath9k

~$

make
然后发现报错了：
./scripts/gen-compat-autoconf.sh /home/renjie/Downloads/compat-drivers-3.9-rc4-2-s/.config /home/renjie/Downloads/compat-drivers-3.9-rc4-2-s/config.mk > include/linux/compat_autoconf.h
make -C /lib/modules/3.2.0-77-generic/build M=/home/renjie/Downloads/compat-drivers-3.9-rc4-2-s modules

make: *** [modules] 错误 2

错误解决：
打开include/linux/compat-3.8.h，找到第49行：
static inline int __must_check kref_get_unless_zero(struct kref *kref)
{
return atomic_add_unless(&kref->refcount, 1, 0);
}
注释掉这个函数：

/*
static inline int __must_check kref_get_unless_zero(struct kref *kref)
{
return atomic_add_unless(&kref->refcount, 1, 0);
}
*/
[/code]接下来继续，

~$

make

~$

make install

~$

modprobe ath9k

然后你就会发现无线网卡可以用了（如果不行重启机器试试）。
