联通宽带频繁掉线

[unijiang]

最近 1 个月，发现宽带频繁掉线， 坐标苏州

• 现象：掉线短则 10 几分钟，长则 6-8 个小时

• 网络拓扑

  • 光猫桥接（禁用了 TR069 ）-> Lede X86 VM （畅网 M1 N200 ，I226V x2 ）-> 交换机
  • Lede: 2025-09-18-plus, 内核 6.12.43 ，WAN 口直通，LAN 虚拟交换机
  • ESXI: 8.0.3

• 尝试（以下均无效果）

  • 更换光猫和软路由之间网线
  • Lede: WAN 口改用虚拟网卡
  • 换光猫

• 日志

  • Lede 系统日志

有没有可能是 1970 年的问题？
