Urgency

Quick answer

An amber light on your Arlo SmartHub or Base Station means a connection problem: no Internet if it is solid or on the Internet LED, or a camera out of range if it blinks slowly. Check the Ethernet cable and power, then restart it for 30 seconds.

Safety first

Stop and check this first

  • Do not unplug the SmartHub while it alternates blue and amber, or the Base Station while its power LED blinks green: Arlo says a firmware update or reset is in progress.

Safe checks you can perform

  • Identify which LED is amber and how
  • Ethernet cable and power
  • Restart the SmartHub or Base Station
  • Test the same cable with a laptop

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Line check by your Internet provider
  • Do not attempt this professional task: Case with Arlo support if it stays offline

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. Line check by your Internet provider

    What they doIf a computer connected to the router with the same cable cannot browse either, your provider or the router manufacturer checks the line and the router.

    They must show youthe line and router status and proof that it provides Internet over cable again.

    In writingthe fault found, the fix and the date.

  2. Case with Arlo support if it stays offline

    What they doIf the router provides Internet over cable and the SmartHub stays amber after a restart and a reset, Arlo support checks the device.

    They must show youthe tests they run on the SmartHub or Base Station and their conclusion.

    In writingthe case number, the diagnosis and, if it is replaced, the reason.

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. Identify which LED is amber and how

    No special tools

    Who:
    you, no tools.
    How:
    check the model on the label. On a single LED SmartHub, tell solid amber (connection error) from slow blinking amber (camera not found or too far). On a multi LED Base Station, see whether the amber is on the power LED (booting), Internet LED (no Internet) or camera LED (camera far away or weak signal). If you just held the Sync button down, wait 15 minutes.
    Result that matters:
    knowing whether the problem is Internet or a camera's range.
    If it is the Internet LED or solid amber:
    check the cable, power and restart.
    If it is the camera LED or slow amber:
    move the camera closer to the SmartHub.
    Evidence to keep:
    a photo of the LEDs with the time and the device model.

  2. Ethernet cable and power

    No special tools

    Who:
    you, no tools.
    How:
    unplug both ends of the Ethernet cable, inspect its whole length for damage, fraying or tears, try a different cable and reconnect it firmly to the SmartHub and the router. Check the power adapter, plug it straight into a wall outlet (no power strip or switched outlet) and try another outlet.
    Result that matters:
    the Internet LED turning blue or green.
    If it turns blue or green:
    the cable or power was the cause.
    If it stays amber:
    restart the SmartHub.
    Evidence to keep:
    which cable and outlet you used.

  3. Restart the SmartHub or Base Station

    No special tools

    Who:
    you, no tools.
    How:
    with the Ethernet cable already connected, unplug the power adapter from the wall, wait 30 seconds and plug it back in; Arlo says the network cable must be connected before the power. Wait about two minutes. If it is connected to an extender or mesh node, connect it directly to the router and make sure the router is not using a VPN.
    Result that matters:
    the Internet LED staying blue or green after booting.
    If it stays blue or green:
    the connection is restored.
    If it is still amber:
    test the cable with a laptop.
    Evidence to keep:
    the restart time and where it is connected now.

  4. Test the same cable with a laptop

    No special tools

    Who:
    you, with a laptop or desktop that has a network port.
    How:
    connect the computer to the router with the same Ethernet cable the SmartHub used and try to open a web page.
    Result that matters:
    knowing whether the router connection or the SmartHub is failing.
    If the computer browses:
    the router works; consider a SmartHub factory reset and, if nothing changes, Arlo support.
    If the computer cannot browse either:
    contact your Internet provider or the router manufacturer.
    Evidence to keep:
    the result of the computer test and the time.

    Resetting the SmartHub or Base Station removes all its cameras from your account and they must be added again.

What it means

Arlo explains that on single LED SmartHubs (VMB5000, VMB4540, VMB4500) solid amber means an error or a connection problem and slow blinking amber means a camera cannot be found or is out of range. On multi LED Base Stations (VMB4000, VMB3500, VMB3000) an amber Internet LED means it is connecting to the router but has no Internet, an amber camera LED means a camera is too far away or the signal is weak, and an amber power LED means it is booting. The light on its own never proves the device is faulty.

Warnings and stop conditions

  • Mediumsource verified

Symptoms and causes

Probable causes · in order

  • Loose or damaged Ethernet cableCommon

    Arlo asks you to inspect the whole network cable between the SmartHub and the router, try another one and make sure it is secure at both ends.

    Evidence: My Arlo SmartHub or Base Station is offline; how can I troubleshoot it?

  • Router without InternetCommon

    If a laptop connected to the router with that same cable cannot browse either, the fault is in the router connection, not the SmartHub.

    Evidence: My Arlo SmartHub or Base Station is offline; how can I troubleshoot it?

  • Power, extender or VPNPossible

    An outlet controlled by a switch, a power strip, a connection to an extender or mesh node instead of the router, or a router using a VPN keep the SmartHub from a stable connection.

    Evidence: My Arlo SmartHub or Base Station is offline; how can I troubleshoot it?

  • Camera far away or with a weak signalPossible

    Slow blinking amber on a single LED SmartHub, or an amber camera LED on a Base Station, means a camera is out of range or has a weak signal.
