INTERNET-ROJO-INTERMITENTE
Movistar INTERNET-ROJO-INTERMITENTE on fibre router: fibre signal below threshold
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
The Internet icon on your Movistar router is blinking red: fibre power is below the threshold. First check that the fibre cable is firmly plugged into the router and the wall socket, with no tight bends and not trapped by furniture.
Safety first
Stop and check this first
- Do not force, bend or step on the fibre cable while checking it: Movistar warns it must not have sections bent at a very tight angle, and a damaged cable stops carrying the signal.
Safe checks you can perform
- Fibre cable connection at the router and the wall socket
- Cable route free of tight bends and crushing
- Turn the router off and on
- Report the fault to Movistar
Leave these tasks to a qualified professional
- Do not attempt this professional task: Measure optical power at the wall socket and the router
- Do not attempt this professional task: Check cable, socket and router before replacing anything

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Measure optical power at the wall socket and the router
What they doThe Movistar technician uses an optical power meter to measure the signal reaching the wall socket and the router and compares it with the operator's threshold.
They must show youthe reading at the socket and at the router against Movistar's threshold.
In writingwhich section loses the signal and what was repaired.
Check cable, socket and router before replacing anything
What they doThe technician checks the fibre cable, its connectors and the wall socket, and only replaces the cable or the router if the measurement points to it.
They must show youthe reading before and after the change.
In writingwhich part was replaced and why.
Before accepting a part or repair

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Fibre cable connection at the router and the wall socket
- Who:
- you.
- How:
- find the fibre cable (green connector) and check it is fully inserted at the router and at the optical wall socket. If either end is loose, take it out and gently plug it back in until it sits firmly.
- Result that matters:
- whether the Internet icon stops blinking red and turns solid blue.
- If it turns solid blue:
- the cable connection was the problem; you can browse again.
- If it keeps blinking red:
- the connection does not explain it; check the cable route.
- Evidence to keep:
- a photo of the router with the light on and of both cable ends.

Cable route free of tight bends and crushing
- Who:
- you.
- How:
- follow the cable from the wall socket to the router and look for very tight bends or sections trapped by furniture, doors or skirting. Reposition it with wide curves without pulling it.
- Result that matters:
- whether the red blinking stops once the cable is freed.
- If it stops:
- a bend or crushed section was cutting the signal; keep the cable in wide curves.
- If nothing changes:
- the cable may be damaged or the signal is lost outside your home; do not cut or splice it.
- Evidence to keep:
- photos of the section that was bent or trapped, if any.

Turn the router off and on
- Who:
- you.
- How:
- turn the router off, wait a moment and turn it back on. Movistar says a restart does not lose your settings.
- Result that matters:
- whether the Internet icon ends up solid blue after startup.
- If it is solid blue:
- the signal is now above the threshold.
- If red blinking returns:
- the signal is still low with the cable in place; report it to Movistar.
- Evidence to keep:
- time of the restart and the light state afterwards.

Report the fault to Movistar
- Who:
- you, by phone or chat with Movistar.
- How:
- explain that the Internet icon is blinking red, the fibre cable is plugged in with no bends, and you already restarted the router.
- Result that matters:
- that Movistar opens a ticket and checks the line.
- If they find a line fault:
- the repair is Movistar's responsibility.
- If they ask for proof:
- show the photos of the light and the cable you kept.
- Evidence to keep:
- ticket number and date of the report.

What it means
Movistar explains that on its HGU (Smart WiFi) router a blinking red Internet icon means the power level arriving over the optical fibre is below the set threshold. Usually the fibre cable is unplugged, badly plugged in, bent at a very tight angle or trapped by furniture. The light does not say where the signal is lost and does not prove the router is faulty: it only says too little light reaches it.
Warnings and stop conditions
- Mediumeditorial warning
Do not force, bend or step on the fibre cable while checking it: Movistar warns it must not have sections bent at a very tight angle, and a damaged cable stops carrying the signal.

Symptoms and causes
Probable causes · in order
- Loose or badly plugged fibre cableCommon
It often appears after moving the router or cleaning behind it. Confirmed if the blinking stops once the connector is seated properly at the router and the wall socket.
Evidence: ¿Qué significa la luz LED roja de tu Router Movistar?
- Bent or crushed fibre cableCommon
The cable is plugged in at both ends but has a very tight bend or is trapped by furniture or a door. Movistar says the light signal does not tolerate those bends.
Evidence: ¿Qué significa la luz LED roja de tu Router Movistar?
- Signal loss outside your homePossible
If the cable is plugged in and free of bends and the blinking continues, low power is no longer explained by what you can see at home. Checking it is Movistar's job.
