Optus 1000M Kept Dropping Out in Rosebery: Simplifying the Wiring and Wiring the Desktop for a Stable Line

Rosebery的Optus千兆总是断网：精简线路、台式机改有线，把连接稳住

A student in Rosebery on an Optus 1000M plan kept losing internet at random, and the router’s Internet and WiFi lights would go dark when it happened. Intermittent faults like this are the hard ones — they come and go, so you can’t just “fix” them in one move. The approach is to simplify the setup, remove variables, and give the connection the most stable path possible.

Rosebery 一位同学用 Optus 的 1000 兆套餐，网络时不时就断，断的时候路由器的 Internet 和 WiFi 灯也会灭。这种时断时续的故障最难搞 — 它来了又走，没法一招修好。思路是：精简配置、去掉变量，给连接留一条尽量稳定的通路。

How we stabilised it on-site现场怎么把它稳住

Mapped when the drops happened先摸清断网的时间和规律

Looked for a pattern to reproduce找可复现的规律

Removed extra / interfering cabling移除多余、可能干扰的线路

Kept only the main feed connected只保留主进线

Power-cycled the router clean干净地断电重启路由器

Fresh start, one variable at a time重新开始，逐一控制变量

Wired-tested the line and speed网线直连测线路和网速

IP normal, hit the full 1000 MbpsIP 正常，跑满 1000 兆

Wired the second-bedroom desktop把次卧台式机改有线

Stable wired link, then observe 2 days有线更稳，再观察两天

First, tell the two kinds of “no internet” apart

先分清两种“没网”

When a device drops, the very first thing to notice is whether the WiFi name is gone entirely, or the WiFi is still there but nothing loads. They look similar but point to different causes, and the router’s lights help you decide before touching anything.

No WiFi name at all → more likely the router’s radio, power or hardware.
WiFi present but no internet → more likely the upstream line, IP/DHCP or WAN side.
Internet and WiFi lights off during a drop points at the router or its feed, not your phone.

设备断网时，第一件要注意的事：是 WiFi 名彻底搜不到了，还是 WiFi 还在、只是打不开网页。两者看着像，原因却不同，而路由器的指示灯能帮你在动手前就判断个大概。

完全搜不到 WiFi 名 → 更可能是路由器无线、电源或硬件。
有 WiFi 但没网络 → 更可能是上游线路、IP/DHCP 或 WAN 侧。
断网时 Internet 和 WiFi 灯都灭 → 指向路由器或它的进线，而不是你的手机。

Two kinds of “no internet” · they point to different causes两种“没网” · 指向不同原因

	WiFi name is gone搜不到 WiFi 名	WiFi is there, but no internet有 WiFi，但没网络
What you see现象	Phone can’t even find the network手机连 WiFi 都搜不到	Connected to WiFi, but pages won’t load连上了 WiFi，但网页打不开
Often means多半是	Router radio / power / hardware issue路由器无线、电源或硬件问题	Upstream line, IP/DHCP or WAN-side issue上游线路、IP/DHCP 或 WAN 侧问题
Check the lights看指示灯	Read the router’s Internet and WiFi lights first — off, blinking or solid narrows hardware vs software fast, before you change anything.先看路由器的 Internet 和 WiFi 灯 — 灭、闪、常亮，能在动手前快速分清是硬件还是软件问题。

On this job the line itself was fine once simplified: with the extra cabling removed and the router restarted clean, a wired test pulled the full 1000 Mbps and the IP came up normally. To give the setup the steadiest path — especially useful for a desktop — we ran a wired connection to the second-bedroom PC and left it to observe over the next couple of days. For faults you can’t reproduce on demand, that’s the honest method: reduce the variables, then watch.

这单精简之后线路本身没问题：拔掉多余的线、干净重启路由器后，网线直连跑满了 1000 兆，IP 也正常。为了给连接一条最稳的通路 — 对台式机尤其有用 — 我们把次卧的电脑改成有线，让同学接下来两天观察。对于没法随时复现的故障，这才是老实的做法：先减少变量，再持续观察。

Result最终结果

On a randomly dropping Optus 1000M line, simplifying the wiring and doing a clean restart brought the connection back to a full 1000 Mbps on a wired test, and the second-bedroom desktop was moved to a stable wired link. Intermittent faults are handled by removing variables and observing, not guessing.

面对时断时续的 Optus 千兆，精简线路 + 干净重启后，网线直连恢复到满 1000 兆，次卧台式机也改成了稳定的有线。时断时续的故障，靠去掉变量 + 持续观察来解决，而不是靠猜。
