以太网适配器无法从 Fritz Box 获取 IPv4 地址

我有一台戴尔 XPS 15 9500（Ubuntu 20.04）。我想使用以太网适配器。我买了一台 DA310，但无法使以太网连接正常工作。

当我连接 USB-C 电缆时，这些设备会显示在lsusb列表中：

Bus 004 Device 003: ID 0bda:8153 Realtek Semiconductor Corp. RTL8153 Gigabit Ethernet Adapter

更新：结果来自dmesg | grep -i r815：

enx747827b4aac4 没有来自路由器的 IPv4 地址。网络信息来自sudo lshw -class network：

为什么 wlp0s20f3 获得了 IPv4 地址，而 enx747827b4aac4 没有？

答案1

它现在对我有用。我安装了 netplan 并从 netplan 开始。
