What does a red LOS light mean on my Maxis router?

LOS means Loss of Signal. The router is not receiving fibre light. This is a line-side fault and needs a Maxis technician.

Maxis Fibre Keeps Disconnecting? Causes & Fixes 2026

Q: Why does my Maxis Fibre keep disconnecting?

Most often a loose fibre cable, an overheating or old router, or WiFi interference. A red LOS light instead points to a fibre line fault that needs a technician.

Q: Should I replace my router if the internet keeps dropping?

If the router overheats or is several years old and drops often, a newer WiFi 6 router or a mesh system usually fixes it.

Maxis Fibre Keeps Disconnecting? Causes & Fixes (2026)

Internet dropping every few minutes or hours, and you keep restarting the router? Most fibre disconnections are a router, cable or WiFi issue you can fix yourself — but some point to a line fault that needs a Maxis technician. Here’s how to tell which, and fix it.

Quick answer

Check the router’s LOS / Internet light: a steady red LOS means a fibre line fault — report it.
If lights look normal, most drops are a loose fibre cable, hot/old router, or WiFi interference — fixable at home.
Frequent area-wide drops at the same times can mean a local network fault we should log for you.

First: read your router lights

What you see	Likely meaning	Action
Red LOS light	Fibre signal lost (line fault)	Report — needs technician
Lights normal, WiFi drops	Router / WiFi issue	DIY fixes below
Drops when router is hot	Overheating / old router	Ventilate / replace

Common causes of disconnection

Loose fibre cable at the wall socket or router (the thin yellow/green cable).
Overheating or ageing router that restarts itself.
WiFi interference (crowded 2.4GHz band, thick walls, far rooms).
Outdated firmware on the router.
Line or area fault (LOS light, or whole neighbourhood drops together).

Fix it step by step

Gently re-seat the fibre cable at both ends (don’t bend it sharply).
Restart the ONU/router (off 30 seconds, on again).
Give the router airflow — not boxed in or in direct sun.
Switch devices to the 5GHz WiFi band and move closer.
Update firmware (or ask us to push it).
If the LOS light is red or drops continue, it’s a line fault — report it for a technician.

What does a red LOS light mean?
Loss of Signal — the router isn’t getting fibre light. This is a line-side fault and needs a Maxis technician.

Does weather affect fibre?
Rarely, unlike older copper lines. Repeated weather-linked drops usually mean a damaged outdoor cable to report.

Should I replace my router?
If it overheats or is several years old and drops often, a newer WiFi 6 router or mesh usually fixes it.
