Ubuntu 12.10 – 网络管理员未列出无线网络

刚刚在我的笔记本电脑上重新安装了Ubuntu 12.10(使用Windows 7进行双启动)。 直到今天访问我的家庭无线网络没有问题。 突然间,网络管理员似乎没有接收任何无线网络。 我的笔记本电脑的无线适配器已打开,我可以在使用Windows 7分区时连接,而我家中的其他所有设备都可以连接。 为什么无线就像这样下降? 如果有帮助,我可以发布我应该运行的任何命令的结果。

执行命令:

 sudo gedit /etc/NetworkManager/NetworkManager.conf 

这将在文本编辑器中打开该文件。 将managed=的行更改为:

 managed=true 

保存并关闭该文件,然后执行:

 sudo killall NetworkManager 

注销并重新登录。

在我的情况下,在我按照另一个答案后,我看到它现在显示device not ready在重新启动后device not ready

这是我为解决这个问题所做的工作:

sudo gedit /etc/network/interfaces我得到了一个包含这个的文件:

 #This file describes the network interfaces available on your system #and how to activate them. For more information, see interfaces(5). #The loopback network interface auto lo iface lo inet loopback #The primary network interface auto wlan0 iface wlan0 inet dhcp wpa-ssid Wifi Name wpa-psk Wifi Pasword 

我删除了下面的所有内容# The primary network interface ,重启后我再次使用无线网络。
