如何查找可用的无线网络

我正在使用 HP Pavilion dv6000，我查看了与此问题类似的其他答案，但是当我查看我的网络符号时，它没有显示以下答案所说的任何内容

“确保您的 wifi 硬件开关是否打开。它位于 F2 或 F12 或靠近它的位置。一旦启用开关，顶部面板（Gnome 网络管理器）上就会出现一个小风扇状的小程序，从右边数第四个。

单击它，如果“启用无线”选项上没有勾选，请启用它。等到您的 wifi 连接名称出现。

它显示“启用网络”，我的 Wi-Fi 开关已打开，我已尝试使用终端来终止小程序，正如另一个答案建议的那样。有人还有其他可能有帮助的想法吗？

如果有人好奇我如何发布此信息，我正在另一台运行旧版本的 ubuntu 笔记本电脑上。

答案1

打开终端CTRL++ALT并T输入以下命令

sudo iwlist scan

这将列出您的电脑可以看到的所有 Wifi 信号，如下所示。

warren@dell:~$ sudo iwlist scan
[sudo] password for warren:
