我正在使用带有 Atheros AR9565 卡的 Toshiba Satellite C-A50 笔记本电脑。尽管“ifconfig”中显示了“wlan0”接口，但没有无线路由器来检查连接。在网络连接下拉菜单中勾选了“启用无线”。eth0 接口工作正常。我已为无线安装了 compat-wireless-3.6.8-1-snpc“ath9k”驱动程序。终端中的“dmesg”命令显示“[ 1972.160105] IPv6：ADDRCONF(NETDEV_UP)：wlan0：链接未准备好”。同样的 Atheros 无线卡在 Windows 7 中正常工作。内核版本也是如此。uname -r 结果 3.5.0-39-generic 我是 Linux 新手，请帮帮我。
lshw -c 网络结果。

答案1
我认为您应该删除该驱动程序并安装这个。 3.5
首先删除当前驱动程序：
cd <to the path of the old driver/compat-wireless-3.6.8-1-snpc>
sudo su
./scripts/driver-select restore
./scripts/driver-select ath9k
make clean
然后将文件拖到桌面上，右键单击它并选择在此处提取：
cd Desktop/compat-wireless-3.5.4-1-snpc
sudo su
./scripts/driver-select ath9k
make
make install
exit
构建和安装后卸载模块和驱动程序：
sudo make unload
sudo modprobe ath9k
編輯：請您做
echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k
然后：
sudo dpkg-reconfigure resolvconf
然后拔下你的以太网连接，看看你的 wifi 是否可以连接。
