### 通过图形化界面重启网络
This is, of course, the easiest way of restarting the network for Ubuntu desktop users. If this one doesn’t work, you can of course check the command line options mentioned in the previous section.

NM-applet is the system tray applet indicator for [NetworkManager][15]. That’s what we’re going to use to restart our network.
NM 程序是 [NetworkManager][15] 的系统托盘程序标志。我们将使用它来重启网络。

接下来，点击该图标（也可以点击声音图标或电池图标）。这会打开菜单。选择“Turn Off”。
