问题描述：

路由器重启了，然后DHCP突然无法获取地址，但是可以手动设置静态地址连接路由器。

过了两小时之后好像环路了，用静态地址直连也ping不通，并且console连接出现connecting to com3 connected

后卡死。进不去命令行，以下是配置 求助

为什么DHCP会获取不到地址

组网及组网描述：

5小时前提问

串口登不进去就不对劲，那个时候除了ping不通还有啥别的现象吗

4小时前回答

所有接口网线灯闪烁一致

路由器作为DHCP客户端无法获取到地址吗，哪个接口

4小时前回答

所有接口

串口应该是能进去，但是命令敲不上，可能是CPU 100%

另外你的说所有灯同时闪，可能就是环路的了，把网线拔一下，看恢复没有，之后再去找环路的问题
