Dell Latitude E6430 - 我没有摆弄过任何东西，所以这是一次让我感到困惑的更新。我现在有了铜线以太网连接，不知何故通过我的 wlp2s0 接口而不是无所事事的 eno1 接口。Wifi 扫描没有发现无线网络。但当我外出时，我必须使用 wifi，所以我被困在这里。
软件更新没有显示任何需要更新的驱动程序。

答案1
我建议使用 NetworkManager 而不是 netplan。然后您可以使用常规 GUI 工具来配置网络设备。
在 中terminal，执行以下操作...
cd /etc/netplan# 更改目录sudo mv existing.yaml existing.yaml.HOLD# 重命名现有文件sudo pico config.yaml# 创建新文件
输入以下文本，保持相同的缩进格式...
network:
version: 2
renderer: NetworkManager
sudo netplan --debug generate# 生成配置文件sudo netplan apply# 应用新的配置文件reboot# 重启计算机
现在转到有线和 Wi-Fi 网络设置面板并配置您的设备。
