刚买的Rock pi s，系统运行的好好的，突然网络连不上了，一看网卡灯不亮了，重新插拔了网线没有反应，重启了一下系统，发现重启过程中网卡灯会闪几下，然后就灭了。换了网线什么的也不行，然后重新刷了系统，发现故障依旧，求解决。
Rock pi s网卡突然不能用了
你可以刷一个 Radxa ROCK Pi S 固件。
接个调试串口线或者是使用 adb 功能查看是否有网卡设备。
可使用命令 sudo ifconfig -a，看是否有网卡 eth0 和分配到 IP。
如果没有 eth0，那就是网卡硬件有问题。
重新刷了固件故障依旧，ifconfig能看到eth0，但是没有IP，ip addr 看eth0的状态是down。已经换过网线，换过电源试过了，还是这样。
有 eth0 的话，
敲一下命令 sudo ifconfig eth0 up。然后发一下 sudo dmesg 的 log过来看一下
或敲入命令 dhclient eth0 后，如果能获取到 IP，说明可联网；如果无法获取到 IP，则电路有问题。

这是log，您看一下
运行dhclient eth0一直都没有反应
运行这一条命令 dhclient eth0 没获取到 ip，说明网卡硬件有问题。
请问一下，在出现这个问题之前，你是做了什么操作吗？
我用这个跑了vscode remote，别的什么都没有跑，突然vscode连不上了，然后就发现网卡灯不亮了
还有把系统更新到最新，然后安装了golang
明白了。我知道你做了什么操作了。
那我这个故障到底是什么原因导致的呢？
造成这个问题的原因，我也不清楚。
好吧，谢谢🙏
