由于配置问题或设备故障导致数据包丢失？

更换 ISP 后，我开始遇到数据包丢失问题，不幸的是，这影响了我的日常浏览和工作活动。典型的 ping 会话到谷歌如下所示：（如您所见，有很多超时，总体上大约为 10-20%）

我运行的设置是：无线路由器位于建筑物顶部，它发出一条以太网电缆连接到我的机器。对于连接，我使用 WAN Miniport (PPPOE)。

我的问题是：这些丢失是因为我这边的以太网卡配置错误造成的，还是 ISP 设置/硬件的问题？任何能帮助我确定问题的工具/建议都将不胜感激。

TIA，佐助

答案1

检查所有接口的速度和双工。尽可能手动设置。咨询您的 ISP 以获取他们的建议。设置自动/自动会导致此类问题。更改为固定速度和双工解决了该问题。

答案2

为了缩小范围，您可以对某个地方进行跟踪路由，并获取路由器的 IP 和路由器之后的第一个跳转。然后 ping 这两个 IP，看看您与路由器的连接是否比路由器与下一个跳转的连接更可靠。如果是这样，您可以向 ISP 投诉。

NAT 环境中的示例：

$ /usr/sbin/tracepath 8.8.8.8
 1:  google-public-dns-a.google.com                        0.081ms pmtu 1500
 1:  10.x.x.x                                              1.369ms 
 1:  10.x.x.x                                              1.189ms 
 2:  192.168.1.1                                           4.319ms  <- Router in my house
 3:  188.xxx.80.1                                          7.047ms  <- Router at the ISP
 4:  82.xxx.192.5                                          7.815ms
