按照正常的应用拓扑将电脑、路由器、猫连接起来后，如果对应路由器指示灯不亮，该问题可能与网线接触不良、故障、端口故障等原因相关，下面就和大家聊聊路由器这类的问题该如何解决吧。
一、SYS灯不亮
SYS系统指示灯是路由器的工作状态指示灯，正常情况下是闪烁的。如果SYS灯不亮有可能是不通电或电源故障，导致系统不能正常启动。如果换了插头或电源设配器还是不亮，路由器有可能是硬件故障了，这种情况基本无法自行解决，一般需要返厂维修。简单点说就是：假如还在保修期，联系卖家走售后吧。
二、WAN灯不亮
WAN灯不亮，有可能是猫（modem）出故障了，正常情况下modem通电的话用网线接到WAN口上是亮的，无论是否有数据正在传输，简单来说就是如果modem不通电或坏了，那路由器的WAN口肯定是不会亮的；如果在modem通电正常运行的情况下，WAN口不亮，则很有可能是网线问题或路由器有问题。那如何确定是网线问题还是路由器问题呢？
可以尝试“替换法”。你可以把原来插在WAN口的网线水晶头拔下来接到任意一个LAN口上，如果对应的LAN口亮的话则代表网线没有问题，是WAN口故障了；如果LAN口也不亮，则代表网线故障了。
三、WIFI灯不亮
WiFi指示灯正常情况下是常亮或闪烁，闪烁表示有数据正在传输，熄灭表示关闭WiFi功能，除了硬件故障导致WiFi灯不亮外，最大的可能就是路由器开启了“WiFi定时开关功能”，如果开启了该功能，直接按路由器背面的“WiFi”按钮2-3秒即可开启。
四、LAN灯不亮
一般来说，用网线将LAN口和电脑连接，电脑工作时，对应的LAN指示灯是会长亮的，有数据传输时会闪烁；如果不亮说明接口或者网线出现问题。接口问题可能是路由器接口或者电脑网卡接口问题。
同样是使用“替换法”，将连接电脑那一端的网线换到另外一台电脑（正常运行的）上看看对应的LAN口是否亮。亮的话则是电脑本地网卡的问题，不亮则是网线或路由器的问题。
以上内容就是和大家介绍的路由器灯亮不了的解决方法了，如果大家在家里使用的路由器灯亮不了的话可以参考一下上面的内容，相信一定能够帮到大家的。
