我系统的是 13.2。用网线联互联网时，桌面上那个黑色上网标志一会儿闪，一会儿又不闪，闪的时候联上网，不闪的时候联不上网。
lshw -C network
把结果全部复制贴上来。
再打开一个终端
sudo journalctl -f
滚动监测系统日志。当出现故障时，把相关的日志贴上来。
suse@linux-337q:~> lshw -C network
If 'lshw' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf lshw
suse@linux-337q:~> su
密码：
