![有线连接失败,但WIFI没问题](https://linux22.com/image/156272/%E6%9C%89%E7%BA%BF%E8%BF%9E%E6%8E%A5%E5%A4%B1%E8%B4%A5%EF%BC%8C%E4%BD%86WIFI%E6%B2%A1%E9%97%AE%E9%A2%98.png)
昨天安装了 Debian,除了无法使有线连接工作之外,体验很愉快。我有一个无线连接,可以连接并允许我访问互联网。有线连接已激活,但没有任何互联网。我安装了网络管理器,希望它能起到一些作用。
ip a(当我同时连接到无线和有线时)

注意到 eno1 缺少 IPv4 地址。
还尝试调整文件
/etc/网络/接口
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
cat /etc/network/interfaces.d/* auto lo iface lo inet 环回
auto eth0
iface eth0 inet dhcp
到目前为止我注意到的一件事是我的以太网在interfaces.d中被称为eth0,而在ip a中被称为eno1。我尝试将etho0更新为eno1,然后重新启动服务,但没有成功。根据我对网络管理器的理解,现在应该忽略接口文件吗?
猫 /etc/NetworkManager/NetworkManager.conf

[ifupdown]
managed=true
任何帮助,将不胜感激!
