ROJO-BLANCO-ALTERNO
Spectrum ROJO-BLANCO-ALTERNO on Wi-Fi router: the router is overheating
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
If the Spectrum WiFi 6 Router light alternates red and white, Spectrum says the device is overheating. Take it out of closed furniture or closets and place it somewhere open and raised, with nothing on top.
Safety first
Stop and check this first
- Do not cover the router or leave it inside closed furniture while it shows the overheating alert.
- Do not hold the button for 15 seconds or more: that resets to default settings and removes your personalised configuration.
Safe checks you can perform
- Router location
- Light after moving it
- Reboot with the Reboot button
- Report to Spectrum
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check the router where it actually sits
- Do not attempt this professional task: Replace the router only after diagnosis

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.
Router location
- Who:
- you.
- How:
- Look at where the router sits. Spectrum recommends an open, raised spot and not a media center, a closet or behind a TV.
- Result that matters:
- Whether the router is enclosed or surrounded by objects.
- If it is enclosed:
- move it somewhere open and raised before going on.
- If it is already in the open:
- location does not explain the alert; go on to the reboot.
- Evidence to keep:
- A photo of how it was placed and how you leave it.

Light after moving it
- Who:
- you.
- How:
- With the router in an open spot, watch the light for a while without touching anything else.
- Result that matters:
- Whether it stops alternating red and white.
- If it returns to solid blue or green:
- the location was the likely cause.
- If it keeps alternating:
- reboot it with the Reboot button.
- Evidence to keep:
- Time of the change and light colour.

Reboot with the Reboot button
- Who:
- you.
- How:
- Press and hold the side Reboot button for 4 to 14 seconds; Spectrum says your settings are not removed this way.
- Result that matters:
- The light colour after startup.
- If it ends solid blue or green and the alert does not return:
- the router is working normally.
- If it alternates red and white again in an open spot:
- contact Spectrum.
- Evidence to keep:
- Time of the reboot and final colour.

Report to Spectrum
- Who:
- you, through the My Spectrum app or Spectrum support.
- How:
- Explain the light alternates red and white, the router is in an open spot and you already rebooted it.
- Result that matters:
- That Spectrum checks the device.
- If they diagnose a device fault:
- Spectrum handles the replacement.
- If they ask for more detail:
- share the location photos and times.
- Evidence to keep:
- Case number and date.

- Networks

What it means
The Spectrum WiFi 6 Router guide assigns the alternating red and white light to the device overheating. The same guide recommends an open, raised location and not inside a media center, a closet or behind a TV. The light warns of high temperature but does not say whether the cause is the location, room heat or an internal fault, and on its own it does not prove the router is faulty.

Symptoms and causes
Probable causes · in order
- Router inside furniture or a closetCommon
Spectrum advises against a media center, a closet or behind a TV. Confirmed if the light returns to normal once moved somewhere open.
Evidence: Spectrum WiFi 6 Router User Guide - Version 13
- Objects on or around itPossible
A router surrounded by objects is not in the open space Spectrum asks for. It stands out because clearing the area helps without changing room.

- Internal device faultLess common
If the light keeps alternating in an open spot, the location does not explain it; diagnosis belongs to Spectrum.
