我正在尝试让我的 PCI 无线 Atheros 922 卡工作。它在 Unity 中被禁用：网络实用程序和桌面（见屏幕截图）http://www.amisdurailhalanzy.be/Screenshot%20from%202012-10-25%2013:19:54.png）
我尝试了多个论坛上的许多建议。安装了 12.10 而不是 12.04，启用了所有接口……等等。我读过有关 aht9 驱动程序的信息……终端显示 Atheros 卡没有硬件或软件锁，尽管如此，它仍然被禁用。到目前为止，没有任何效果，卡仍然被禁用。任何帮助都非常感谢。以下是更多技术细节：

任何帮助都非常感谢...谢谢，菲利普
2012 年 10 月 31 日...我还有一些更新。当我执行以下命令时，它确实可以看到我的 Wifi 路由器...因此，即使它仍然被禁用...该卡似乎可以工作并可以看到路由器（ESSID：“5791BC26-CE9C-11D1-97BF-0000F81E”）见下文：

答案1
这是我找到的解决方法...
由于 Ubuntu 的 UI 明显有问题，而且网卡似乎没问题（“sudo iwlist wlan1 扫描” 可以正确找到我的路由器），我决定尝试设置 Ubuntu 的连接服务器方式 = 没有 UI！
在终端中（CTRL + ALT + T）：
sudo apt-get install wpasupplicant
然后我使用 wpa_passphrase，将我的 SSID 和密码传递给它
wpa_passphrase <MySSID> <MyPassphrase>
该命令的输出如下：
network={
ssid="<MySSID>"
#psk="<MyPassphrase>"
psk=2131b1234fe9ff60abcda4471e773a6ca28a49b6401810abcd2288c2468653a9
}
然后我编辑了文件 /etc/network/interfaces
sudo nano /etc/network/interfaces
并将其附加到文件
#The wireless interface
auto wlan1
iface wlan1 inet dhcp
wpa-ssid <MySSID>
wpa-ap-scan 1
wpa-key-mgmt WPA-PSK
wpa-psk <psk obtained by the wpa_passphrase command above>
我重新启动后，终于可以访问网络、浏览等等。请注意，Ubuntu UI 仍然处于运行状态，并且仍然显示无线已禁用。
感谢 ModelR 的帖子，我用它来以 Ubuntu 服务器方式设置 Wifi：
http://modelr.wordpress.com/2009/06/01/how-to-get-wireless-network-on-ubuntu-server/
如果有人对如何使 UI 正常工作有想法，我仍然愿意尝试一下......
答案2
在终端中尝试此命令（Ctrl++ Alt）T
rfkill unblock 1
在类似情况下工作正常。
答案3
在终端中尝试这些命令( Ctrl++ Alt)T
sudo modprobe -r iwlagn
sudo modprobe iwlagn bt_coex_active=0
输入第一行，按回车键，输入密码。然后输入第二行。
现在，看看您是否可以连接。
