新安装的 12.04 版本没有 WiFi

我是一名新手，刚刚在我的 Intel I3-550 自制电脑上安装了 12.04。WiFi 应该有 GUI 吗？应用程序列表中没有提到它。

我以前的电脑是 Windows 操作系统，右下角有一个小图标，点击后会显示该区域的网络。Ubuntu 就是这样工作的吗？

现在我通过以太网连接，但不清楚如何通过 WiFi 连接。

答案1

如果 wifi 无法使用，则首先应使用电缆/LAN 网络连接您的 PC/笔记本电脑，然后尝试以下步骤：-

在 ubuntu 中打开“附加驱动程序”选项（按 Windows 键并找到“附加驱动程序”，或者您也可以在“系统设置”中找到此选项），

它将自动为您的电脑/笔记本电脑找到正确的驱动程序并选择选项进行安装。

一般来说它会找到 wifi、图形专有驱动程序。

答案2

  • 要在 Ubuntu 中启用 wifi，请单击顶部面板上的网络图标。

  • 然后启用 wifi。之后，它会搜索附近的 wifi 网络，如果已打开则自动连接，如果已保护则提示输入密码。
