我该怎么做才能检查是否有人断开了我的互联网连接？

在过去的 8-10 个月里，我的互联网每天断线 50-60 次，有时每小时断线 10-12 次。我联系过我的 ISP 20-30 次。ISP 的官员告诉我，他们那边一切正常。我刚刚用 KIS 2016 进行了全面扫描，没有在我的计算机中检测到任何威胁。我怀疑有人恶意切断了我的互联网连接。我想知道我可以做什么来检测和防止这种情况。下面给出了最近的日志。出于安全原因，IP 地址已被隐藏。我使用的是 Netgear DGN 1000。

信息：

  • 这不是硬件问题，因为即使用 D-Link 调制解调器替换当前的调制解调器路由器后问题仍然存在。

假设：您的服务是 ADSL

您看到的是 PPPoE 断开连接并重新链接。以下几种情况会导致这种情况：

  • 同步问题：排除，因为日志应该显示同步消息
  • DSLAM 到 RAS：ISP 端网络问题，常见于超载或故障链接。重度用户将看到最多的断线。ISP 否认这种情况并不罕见。
  • 一个 CSI 上有多个 PPPoE 客户端：如果网络上的其他设备正在尝试对 RAS 进行 PPPoE 呼叫，它将断开现有会话。这将导致循环断开连接。检查所有游戏机、NAS、CCTV 摄像机和计算机是否启用了 PPPoE 连接。如果启用了，请禁用它。CCTV 和游戏机是最常见的罪魁祸首。

最后，确保您的连接在调制解调器中设置为固定/始终开启，但如果这在您购买 Netear 之前发生，则不太可能如此。
