TELUS modem keeps restarting? How to break the loop

A modem that reboots itself is crying for help — usually about heat, power, or a failing unit. The loop won't fix itself, but it's very fixable. Work through these in order.

Cool it down first

Hot box + restart loop = overheating shutdown. Move it out of the cabinet, off the carpet, away from the TV stack. This single step ends more restart loops than anything else.

2 minutes

Check the power path

Loose cords and overloaded power bars cause brownouts the box reads as 'turn me off.' Firmly seat the cord at both ends — then try a direct wall outlet for a day. Loops that vanish on wall power were the power bar all along.

One proper restart, then hands off

Unplug 60 seconds, plug back in, walk away for 5 minutes. If it settles and STAYS settled, you were overheating — keep it cool and you're done. If it restarts again on its own, keep going.

Watch the light during the loop

Note where in the cycle it dies: instantly (power), after a minute (can't reach the network), or randomly (failing hardware). This tells a technician — or TELUS — exactly where to look.

When the box is done

A hub that loops after cooling and clean power is failing. If it's under warranty, that's a TELUS replacement call — and we'll document the fault pattern for you. Out of warranty? A replacement box plus proper placement usually costs less than months of fighting a dying unit.

Safety: if you ever smell burning or see melted plastic around the power port, unplug it and do NOT restart — that unit needs replacing, full stop.

Quick answers

Why does my TELUS modem keep restarting itself?
Overheating, flaky power, or failing hardware — in that order of likelihood. Cooling and clean power cost nothing; test both first.
Will updating fix my restarting modem?
Sometimes — firmware updates fix known restart-loop bugs. But a hot or dying unit restarts no matter what the software says.
Should I factory reset a modem that keeps restarting?
Not first — a reset wipes your settings and rarely fixes hardware-level loops. Try cooling and power first; reset only as a last resort, with your WiFi details written down.
