无法连接 wifi

我刚刚安装了最新版本的 ubuntu，但无法连接到 WiFi。我以前没有用过 ubuntu，所以我很难让它工作。我有一台使用 Windows 10 的 Acer Aspire 笔记本电脑。无线适配器在 Windows 10 上运行良好，但在 ubuntu 上，当我单击网络部分时，它只显示有线连接。它找不到 WiFi。我没有电缆，所以我无法使用有线连接来启动它。有人能帮忙吗？

谢谢

我找到了一个简单的解决方案：

  • 打开“网络设置”
  • 选择“连接到隐藏网络”
  • 对于网络名称，请输入网络的名称（在我的情况下是“Gostinnyi dvir”）
  • 对于网络安全，选择“WPA 和 WPA2 个人版”
  • 然后只需输入密码即可。
