A student in Zetland on a Telstra 100Mbps DSL plan suddenly had no internet — the Telstra gateway’s lights were out and no WiFi showed up. It’s easy to blame the provider or the line. We brought a DSL-capable router on-site, plugged it into the same phone socket, and it was online in minutes — proving the line and plan were fine. The real fault was the Telstra gateway itself: it kept restarting on its own.
一位住在 Zetland、用 Telstra 100 兆 DSL 套餐的同学突然断网——Telstra 光猫指示灯不亮、也搜不到 WiFi。这种情况很容易怪运营商或线路。我们自带一台支持 DSL 的路由器上门，插到同一个电话口上，几分钟就联网了——说明线路和套餐都没问题。真正的故障是 Telstra 光猫本身：它在不停地重启。
When our DSL router synced on the same socket, the line lit up fine — so the fault sat on the gateway, not the DSL line or Telstra.把我们的 DSL 路由器插到同一个口就正常同步了——所以故障点在光猫，不是 DSL 线路、也不是 Telstra。
| DSL lineDSL 线路 | The router / gateway路由器 / 光猫 | |
|---|---|---|
| In this case本例结果 | Fine正常 | Faulty (reboot loop)故障（反复重启） |
| How to test怎么测 | Plug a known-good DSL router into the same socket把一台确定可用的 DSL 路由器插到同一个口 | Watch its lights: looping / never settling = bad看它的指示灯：一直循环、始终不稳定 = 坏了 |
| Quick clue快速判断 | If a second router gets online on the same line, the line is fine and the original box is the problem. Test wired where you can, and give a suspect gateway a stable power outlet — unstable power can shorten a router’s life.如果换一台路由器在同一条线上能联网，说明线路没问题、是原来的设备坏了。尽量用有线测试；给可疑的光猫接一个稳定的电源——电源不稳可能缩短路由器寿命。 | |
Root cause: the Telstra gateway had failed and was stuck rebooting — not the DSL line or the Telstra plan. We got the student back online the same visit on a DSL router and recommended replacing the dead gateway with a known-good unit on a stable power outlet.
根因：Telstra 光猫已损坏、卡在反复重启——不是 DSL 线路、也不是 Telstra 套餐。我们当场用 DSL 路由器帮同学恢复上网，并建议把坏掉的光猫换成一台确定可用、接稳定电源的路由器。
