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

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.

How we stabilised it on-site

Mapped when the drops happened

Looked for a pattern to reproduce

Removed extra / interfering cabling

Kept only the main feed connected

Power-cycled the router clean

Fresh start, one variable at a time

Wired-tested the line and speed

IP normal, hit the full 1000 Mbps

Wired the second-bedroom desktop

Stable wired link, then observe 2 days

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

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.

Two kinds of “no internet” · they point to different causes

	WiFi name is gone	WiFi is there, but no internet
What you see	Phone can’t even find the network	Connected to WiFi, but pages won’t load
Often means	Router radio / power / hardware issue	Upstream line, IP/DHCP or WAN-side issue
Check the lights	Read the router’s Internet and WiFi lights first — off, blinking or solid narrows hardware vs software fast, before you change anything.

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.

Result

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.
