请帮忙
我按照我大学的这些步骤来远程访问远程 VPN，但在安装成功后（目前它可以正常工作，我可以完全访问 PressReader；这就是重点），所以我重新启动了我的笔记本电脑，并重新启动了我的 WiFi 和以太网图标消失，网络停止工作。
这些是我遵循的步骤（葡萄牙语）。 https://www.ccuec.unicamp.br/ccuec/material_apoio/tutorial_linux_vpn_18_04
我在使用此命令重新启动网络管理器时解决了以太网问题：sudo systemctl restart NetworkManager 但 WiFi 仍然无法正常工作。
你们能帮我重建我原来的配置吗？

这似乎可行 但我仍然通过以太网（电缆）连接
当我断开电缆连接时，会出现一个？在 wifi 图标前 并且网络在应用程序或浏览器中不起作用
请帮我摆脱困境 因为它在巴西狂欢，没有大学的支持
谢谢
