@ropon 你没发现 xiaoqiang 这个 IP 丢包率很高么？这个不是你路由器 IP 么？

[wwbfred]

看起来像是从你家到机房的线路没搞好.
把这个给师傅看,或直接 10000 号叫客服转接技术,把这个发给过去后应该会有懂的人联系你.

[wwbfred]

再多做几个测试,看看是不是都经过这个 171.221.71.1.
再 ping 下网关记录下以作对比.

[bclerdx]

请看下你网关的延迟情况。

[justs0o]

@ropon 到你本尼网关延迟都不稳定，肯定是路由器或者光猫除了问题，要么就是线路解除不良

[bclerdx]

@justs0o 对，他那运营商侧网关抖动厉害。

[bclerdx]

@ropon 你本地路由器网关延迟呢。

[shikkoku]

Xiaoqiang?不就是小米路由器吗？

[ropon]

@bclerdx ping 路由器正常，前面截图是直接用电脑连接光猫拨号，或者将光猫改成路由模式
也存在延迟很高的情况，工程师再次上门排查，说线路正常，正在检测光猫，
如果光猫正常，那应该是上层设备有异常。

[ropon]

检测结果：很尴尬，说拨号次数多了，IP 地址冲突所以导致延迟较高，换百兆旧光猫测试延迟正常。

[bclerdx]

@ropon 你把路由器或光猫断电 10 分钟。然后再次通电并拨号，看看延迟吧。
