Risk level

Low

Usually safe to check without specialist tools.

Urgency

Medium

Quick answer

With a solid blue and a blinking green LED, the Blink Sync Module is offline and trying to rejoin its previous wifi network. Check whether your wifi password changed, then power cycle the router first and the Sync Module second.

Safety first

Stop and check this first

  • While the Sync Module is offline, the cameras that rely on it show blurred in the app: don't count on them until solid blue and green return.

Safe checks you can perform

  • Network requirements and wifi password
  • Router and Sync Module power cycle
  • Simplified network without pods or extenders

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Wifi network check by your provider or installer
  • Do not attempt this professional task: Blink Technical Support

What a technician must be able to justify

Technician visit

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.

  1. Wifi network check by your provider or installer

    What they doYour provider or network installer checks the network meets Blink's requirements and reviews the main router and the placement of pods and extenders.

    They must show youthe Sync Module on solid blue and green after the check.

    In writingwhat was changed on the network and where each device ended up.

  2. Blink Technical Support

    What they doIf the Sync Module stays offline after deleting and re-adding it, Blink Technical Support reviews the case.

    They must show youwhat they checked on the account and the device.

    In writingthe case number and conclusion, with the reason if they propose replacing the Sync Module.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

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.

  1. Network requirements and wifi password

    No special tools

    Who:
    you.
    How:
    confirm your network meets Blink's requirements and that the wifi password hasn't changed since you set up the Sync Module. If it changed, update it from the app.
    Result that matters:
    whether the password is still the same.
    If it changed:
    update the Sync Module wifi in the app; that is the likely cause.
    If it is the same:
    power cycle router and Sync Module.
    Evidence to keep:
    note the date of the last password change, if any.

  2. Router and Sync Module power cycle

    No special tools

    Who:
    you.
    How:
    unplug the router for 30 seconds and plug it back in. Then disconnect the Sync Module for 10 seconds and plug it back in.
    Result that matters:
    whether solid blue and solid green appear after the restart.
    If solid blue and green:
    it has reconnected to the network.
    If green still blinks:
    re-enter the wifi password in the app.
    Evidence to keep:
    photo of the LEDs after the restart.

  3. Simplified network without pods or extenders

    No special tools

    Who:
    you.
    How:
    disconnect pods or extenders and leave only the main router on; once the Sync Module connects, you can reconnect them.
    Result that matters:
    whether the Sync Module reconnects on the simplified network.
    If it reconnects:
    the extended network was interfering; place it with the main router in mind.
    If it doesn't:
    Blink says to delete and re-add the Sync Module in the app.
    Evidence to keep:
    note which network devices were on for each attempt.

What it means

Blink explains that a solid blue LED with a blinking green LED means the Sync Module is offline and attempting to reconnect to the previously configured wifi network. The app shows a "Sync Module is Offline" banner and the cameras that rely on it appear blurred. Blink lists power interruptions or being unplugged for a long time, updated wifi settings such as a new password, and interference from pods and extenders as causes. The alert doesn't prove the Sync Module or the cameras are faulty.

Symptoms and causes

Probable causes · in order

  • Wifi password or settings changedCommon

    If you changed the password since the last setup, the Sync Module can't rejoin until you update it in the app.

    Evidence: Sync Module Troubleshooting

  • Power cut or unplugged for a long timePossible

    After an outage or a long time without power, the Sync Module may keep trying to reconnect. It shows if it coincides with a power cut.

    Evidence: Sync Module Troubleshooting

  • Interference from pods or extendersPossible

    Blink asks you to disconnect pods and extenders and leave only the main router; if it reconnects then, the extended network was the cause.
