#1

问题描述:
reboot重启会导致网络连接错误;
shutdown再开启电脑网络正常。

系统:

#2

什么样的错误?有截图吗?


#3

你至少给点截图或者 log 啊…

#5

难道是网卡没有重启

手动解决可以试试

sudo systemctl restart NetworkManager

#6

你看一下 systemctl status -l network.service 把结果贴出来


#7

不起作用。

我就想看下是 NetworkManager 还是 Wickedd。在 NM 确定不好用的情况下,运行下 sudo journalctl -U NetworkManager,拉到最下面把最新的那次连接的消息发出来看看。

输入:
sudo journalctl -u NetworkManager

输出:

#11

dhcpd 的问题,取不到 IP


#12

请问有办法修复吗


#13

能啊,重启完上不了网的时候、运行下:

dhclient -v eth0

看看日志

先把 NM 关了,systemctl stop NetworkManager,然后再 dhclient -v eth0 看看。同时看下 lsmod,也有可能是出于某种原因重启后网卡驱动认成别的了。


#16

关闭 NM(systemctl stop NetworkManager)后,运行dhclient -v eth0 得到:

现在看起来是 NM 自己的问题。你在 /etc/NetworkManager/NetworkManager.conf 里加上:

[logging]
level=DEBUG

看看 systemd 的日志还跟以前一样不?


#18

添加后reboot,网络依然连接不了。

是用 journalctl -U NetworkManager 看,status -l 看到的只有一小部分


#20

不好意思啊,我是小白:sweat_smile:
journalctl -u NetworkManager
这个命令的结果太多了,是需要grep哪个关键词呢?
