为什么路由器不跳线
音乐狂人 根据标准规范，普通网线的最大有效传输距离极限就是100米。一旦超过这个物理极限，网络信号就会衰减到路由器无法识别的程度，从而造成WAN口指示灯不亮的现象。

simulates real failure situation. For networks, according to actual measurements, the maximum effective transmission distance of ordinary network cables is 100 meters, and the bandwidth is pinched. Once exceeded, it will result in packet loss and lag. Remember to buy a gigabit switch to boost the signal! Even if you investigate for a long time, there won't be no signal.
原来如此，一直以为是路由器坏了或者线序错了，看来确实是物理距离导致的信号衰减，涨知识了。
