调制解调器和互联网：解决低连接和延迟峰值问题？

所以我买了一个 tp-link TD-8817 adsl2+ 调制解调器，但有时连接会断断续续。开箱后它无法连接，因此请按照快速连接向导进行设置：

  1. 选择时区
  2. 选择动态 IP（我的 ISP 就是这样工作的）
  3. 将 VPI 设置为 0，将 VCI 设置为 33，然后将连接类型设置为桥接 IP LLC

最近，当我遇到连接不良时，我会 ping 调制解调器，它会反复显示以下模式。

到目前为止我已经尝试过什么。

  • 打开和关闭
  • 恢复出厂设置
  • 将 adsl 模式更改为自动、G.DMT 和 G.Lite
  • 已完成直接连接和通过 wifi 路由器的测试
  • 更换了电缆和微型过滤器
  • 将其直接连接到主电话插座，无需微型滤波器。
  • 执行 ipconfig /renew /release /flushdns
  • 确保我的电脑是网络上唯一的设备，并且没有像种子一样的后台下载
  • 使用装有 win10 的 PC 和装有 linux 的笔记本电脑进行测试

此外，在过去，它给我带来了问题，即使在重启后，ping 值仍然长时间保持在 2000ms+ 左右。

关于如何修复此问题或我遇到的任何特定问题，您有什么建议吗？提前谢谢！

答案1

按照 Yorik 的建议，在没有网络交换机和其他设备连接的情况下尝试了所有方法，现在一切都解决了，虽然我无法指出某件特定的事情，但它解决了我的问题！
