Answer 1

使用iwlist 。 man页（实际上是http://manpages.ubuntu.com/manpages/wily/en/man8/iwlist.8.html ）说：

 wlist.8.gz Provided by: wireless-tools_30~pre9-8ubuntu1_i386 NAME iwlist - Get more detailed wireless information from a wireless interface SYNOPSIS iwlist [interface] scanning 

喀嚓…

 PARAMETERS scan[ning] Give the list of Access Points and Ad-Hoc cells in range, and optionally a whole bunch of information about them (ESSID, Quality, Frequency, Mode...). The type of information returned depends on what the card supports. Triggering scanning is a privileged operation (root only) and normal users can only read left-over scan results. By default, the way scanning is done (the scope of the scan) is dependant on the card and card settings. This command takes optional arguments, however most drivers will ignore those. The option essid is used to specify a scan on a specific ESSID. With some card/driver, this enables to see hidden networks. The option last does not trigger a scan and read left-over scan results. 

“如何连接到无线……”是另一个问题，应该在另一个问题post中自行提出。

如果您安装了图形环境，桌面上应该有一个网络指示器图标（大部分时间位于屏幕顶部的栏中），您应该可以在其下拉菜单中找到您的网络。 单击网络指示器图标，然后选中启用Wi-Fi以显示所有可用的Wi-Fi网络。 单击您的网络，填写密码，它应该连接。
