ubuntu安装r8125网卡2.5G驱动

网上很多说要去编译驱动其实使用5.10以上内核就可以

linux-headers-5.10.0-051000_5.10.0-051000.202012132330_all.deb
linux-headers-5.10.0-051000-generic_5.10.0-051000.202012132330_amd64.deb
linux-image-unsigned-5.10.0-051000-generic_5.10.0-051000.202012132330_amd64.deb
linux-modules-5.10.0-051000-generic_5.10.0-051000.202012132330_amd64.deb

#进入目录安装：
dpkg -i *.deb

查询网络

ip addr

2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000

编辑 00-installer-config.yaml 文件增加 enp2s0 配置

vi /etc/netplan/00-installer-config.yaml

network:
	ethernets:
		enp2s0:
			dhcp4: true
	version: 2

生效配置

netplan apply
