Telstra DSL Router With Every Front Light Off in Sydney CBD (Chinatown): the Router Was Dead, Not the Line

悉尼CBD唐人街：Telstra DSL 路由器前排指示灯全灭，坏的是路由器不是线路

A student living near Chinatown in Sydney CBD had lost internet completely. The Telstra-supplied router on their DSL (phone line) service showed no front panel lights at all — only a faint glow at the back — and repeated power cycles changed nothing. The line was fine; the router hardware had failed. We put our own TP-Link router on the same wall socket, restarted the modem side from the Telstra app, waited for the DSL light to go solid, and rebuilt the WiFi.

一位住在悉尼 CBD 唐人街附近的同学彻底断网了。这条 Telstra 的 DSL（电话线）服务，原装路由器前面板一个灯都不亮——只有机身后侧还有一点微光——反复断电重启也毫无变化。线路本身没问题，是路由器硬件挂了。我们把自带的 TP-Link 接到同一个墙口，用 Telstra APP 远程重启 modem 端，等 DSL 灯变常亮后重新设置好 WiFi。

The give-away was the front panel: no power, no DSL, no WiFi light at all, with only a faint glow at the back of the unit. A line fault normally still leaves the router lit up with a DSL light that flashes or sits red. Nothing lit at the front points at the router hardware itself.最明显的线索就是前面板：电源灯、DSL 灯、WiFi 灯全灭，只有机身后侧还有一点微光。线路故障通常路由器还是亮着的、只是 DSL 灯在闪或变红。前面板整排都不亮，指向的是路由器硬件本身。

What we did on site

上门当天做了什么

How we isolated it on-site现场怎么一步步定位

Power cycled the supplied Telstra router several times, on different outlets把原装 Telstra 路由器反复断电重启，还换了插座试

front panel stayed dark前面板始终不亮

Checked the back of the unit - only a faint glow, no normal boot sequence查看机身后侧，只有微光，没有正常的开机灯序

hardware call: dead判断：硬件已坏

Connected our own TP-Link router to the same DSL wall socket把我们自带的 TP-Link 路由器接到同一个 DSL 墙口

same line, different box同一条线、换台设备

Restarted the modem side from the Telstra app while the new router synced用 Telstra APP 远程重启 modem 端，同时等新路由器同步

DSL light flashingDSL 灯开始闪

Waited for the DSL light to go from flashing to solid, then tested等 DSL 灯从闪烁变常亮后测试

line back up网络恢复

Set the WiFi name and password back up and reconnected their devices重新设置 WiFi 名称和密码、把设备都连回去

25 Mbps plan restored25兆套餐恢复正常

This was an older Telstra DSL service running over the phone line on a 25 Mbps plan. That is worth knowing because it changes what a normal repair looks like: the DSL sync light is the single most useful indicator on the box.

No front lights at all after several power cycles is not a line problem - it is a dead unit.
We keep a spare router in the van precisely for this, so the diagnosis and the fix happen in the same visit.
The Telstra app can restart the modem side, which helps the replacement router sync faster.
A DSL light that flashes then goes solid means the line has synced; if it never goes solid, the fault is upstream, not in the router.
We saw more than one dead Telstra router in the CBD that same week, so if your box is completely dark, you are not the only one.

这是一条比较老的 Telstra DSL 服务，走电话线，套餐 25 兆。知道这一点很重要，因为它决定了正常的排查长什么样：DSL 同步灯是这台设备上最有用的一个指示灯。

反复断电重启之后前面板一个灯都不亮，这就不是线路问题，是设备本身挂了。
我们车上常备备用路由器，就是为了这种情况——诊断和修复能在同一次上门里完成。
Telstra APP 可以远程重启 modem 端，能让替换上去的路由器更快同步。
DSL 灯先闪后常亮，说明线路已经同步；如果一直不常亮，那问题在线路上游，不在路由器。
那一周我们在 CBD 一带遇到不止一台彻底不亮的 Telstra 路由器，所以如果你家的盒子整个是黑的，不止你一个。

Dead router or just needs a restart? How to tell before you call anyone

路由器是真坏了还是只要重启？打电话之前先这样判断

Dead unit vs needs a restart设备已损坏 vs 只是需要重启

	Router hardware has failed路由器硬件已损坏	Line or session problem线路或拨号会话问题
Front lights前面板灯	Nothing lights up, even after several power cycles反复断电重启后仍然一个灯都不亮	Power light normal, DSL or internet light flashing or red电源灯正常，DSL 或 internet 灯在闪或变红
Power cycle断电重启	No change on any outlet换插座也没有任何变化	Often recovers, or at least changes the light pattern经常能恢复，至少灯的状态会变
WiFi nameWiFi 名称	Network stops broadcasting entirelyWiFi 名称完全搜不到了	WiFi still visible, but no internet through itWiFi 还能搜到，只是连上没网
What fixes it怎么修	Replace the router, then re-sync and set up WiFi again换掉路由器，重新同步并重设 WiFi	Restart the modem side, check cabling, or contact the provider重启 modem 端、检查线路，或联系运营商

If your router goes completely dark, the sequence below saves a lot of time before anyone comes out.

Try the power adapter in a different wall socket - it rules out the outlet and sometimes the adapter itself.
Look at the back of the unit as well as the front; a faint glow with a dark front panel is a bad sign.
Note whether the WiFi name still appears on your phone. If it has vanished, the router is not running at all.
If you have a spare router, put it on the same socket. If that one gets a DSL sync, the old box was the problem.
On an older DSL plan, it is also worth checking what speed you are actually paying for and comparing it against what is available now.

如果你的路由器整个不亮了，按下面的顺序先自查一遍，能省下很多时间。

把电源适配器插到另一个插座试试——可以排除插座，有时也能排除适配器本身。
前面板和机身后侧都看一眼；前面板全灭、后面只有微光，是个不好的信号。
看手机上还能不能搜到原来的 WiFi 名称。如果连名字都消失了，说明路由器根本没在运行。
如果手里有备用路由器，接到同一个墙口试。若它能拿到 DSL 同步，那就是老设备的问题。
如果你用的是比较老的 DSL 套餐，顺便看看自己实际在用的速率，和现在能选的方案对比一下。

Result最终结果

Root cause: the Telstra-supplied router had failed outright - no front panel lights after repeated power cycles, not a DSL line fault. A replacement TP-Link router on the same socket synced and the 25 Mbps service came back in the same visit, WiFi name and password rebuilt before we left.

根因：Telstra 原装路由器彻底损坏——反复断电重启后前面板仍全灭，并不是 DSL 线路故障。同一个墙口换上 TP-Link 后成功同步，25 兆的服务在当次上门内恢复，走之前 WiFi 名称和密码也一并重新设置好。
