我看到很多“wifi 连接，但没有互联网”的问题。我的问题恰恰相反，“有互联网，但没有连接” :)
嗯，显然可以连接，因为有网络。问题是我在设置中看不到 wifi 适配器。
我在其他帖子上看到，这个适配器（rtl8821ce）没有官方驱动程序，所以我安装了自己找到的任何东西，希望适配器/wifi 最终会出现在设置中。
如果有什么问题的话，即使没有我的附加驱动程序，电脑也可以连接到互联网。唯一的问题是没有显示连接。
使用无线信息脚本，我得到了以下结果：

总之，Ubuntu 22.04 有没有办法正确检测此卡并显示连接及其设置？
答案1
您的 netplan 文件建议您手动配置网络，而无线则完全缺失。但是，您希望网络管理器配置网络并包括无线。请在终端中执行以下操作：
cd /etc/netplan
sudo rm 00-installer-config.yaml
接下来写入新文件：
sudo nano 01-network-manager-all.yaml
写下以下内容：
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
Netplan 对缩进、间距等非常具体，因此请仔细校对两遍。保存（Ctrl+o 然后按 Enter）并退出（Ctrl+x）。然后执行以下操作：
sudo netplan generate
sudo netplan apply
重启。有什么改善吗？
