或者试一下这样
ethtool -s enp2s0 autoneg off speed 1000(或者100) duplex full

142没有默认安装rp-pppoe，你安了这个试试

Ethtool是用于查询及设置网卡参数的命令。
概要：
ethtool ethX //查询ethX网口基本设置
ethtool –h //显示ethtool的命令帮助(help)
ethtool –i ethX //查询ethX网口的相关信息
ethtool –d ethX //查询ethX网口注册性信息
ethtool –r ethX //重置ethX网口到自适应模式
ethtool –S ethX //查询ethX网口收发包统计
ethtool –s ethX [speed 10|100|1000]\ //设置网口速率10/100/1000M
[duplex half|full]\ //设置网口半/全双工
[autoneg on|off]\ //设置网口是否自协商
[port tp|aui|bnc|mii]\ //设置网口类型
