我想从无线网络转移到以太网。我的电脑是 Lenovo Thinkpad Carbon Gen II。这台计算机没有以太网端口。您必须依赖加密狗。我仍然拥有计算机附带的那个（看起来像这）。因为随着时间的推移，我的有点损坏了。今天，我买了一个新的一个（USB 转 RJ45 适配器）在亚马逊上。我找不到让它发挥作用的方法。欢迎任何帮助。

答案1
为了测试连接是否正常工作：
ifconfig enp0s25 up（这将启用您的网络接口/加密狗）
dhcpcd （这会启动 dhcp 客户端以获得 IP 地址）
当此方法有效时，您可以转向更永久、更方便的解决方案：
例如，您可以使用 netctl 来自动连接。你必须做什么：
/etc/netctl/my_dhcp_profile以您喜欢的方式创建配置文件；您也可以创建多个。例如：Interface=enp0s25 Connection=ethernet IP=dhcp或者（静态IP）：
Interface=enp0s25 Connection=ethernet IP=static Address=('10.1.10.2/24') Gateway=('10.1.10.1') DNS=('10.1.10.1')启用配置文件：
netctl enable my_dhcp_profile netctl start my_dhcp_profile
之后，它将在可用时自动激活，并且不需要进一步交互。基本上start是现在启动它所必需的，而不是在重新启动后启动。您也可以使用stop手动停用它。
