Arlo Doorbell Offline — How to Fix

What Does This Error Mean?

An Arlo doorbell offline means it has lost connection to the Arlo cloud or, on Wire-Free models, to the Arlo Smart Hub. Check the doorbell's battery, Wi-Fi signal, and Smart Hub status.

Affected Models

Arlo Video Doorbell
Arlo Wire-Free Video Doorbell
Arlo Essential Video Doorbell
Arlo Audio Doorbell

Common Causes

Doorbell battery dead or weak (Wire-Free model)
Smart Hub or base station offline (Wire-Free model)
Weak Wi-Fi signal at the door
Wi-Fi password changed and doorbell has stale credentials
Doorbell firmware out of date or stuck

How to Fix It

Check the LED on the doorbell.

Arlo doorbells have a status LED. Solid blue = connected. Off or red = no connection. The exact pattern is in your model's manual.
Charge the doorbell (Wire-Free).

Wire-Free Arlo doorbells use a built-in rechargeable battery. Remove the doorbell from its mount and charge with the included USB cable. Low battery is the most common cause of offline status.
Check the Smart Hub or base station.

Some Arlo doorbells (older Wire-Free models) connect through an Arlo Smart Hub. If the Smart Hub is offline, the doorbell will be too. Verify the hub is plugged in and shows green LEDs.
Verify Wi-Fi signal at the door.

Wired Arlo doorbells connect directly to your home Wi-Fi. Weak signal at the door causes offline status. Add a Wi-Fi extender or relocate the router.
Re-add the doorbell.

If the Wi-Fi password changed or the doorbell remains offline after a battery charge, factory reset and re-pair. Long-press the doorbell reset button until the LED indicates reset, then add the doorbell fresh in the Arlo app.

When to Call a Professional

Arlo support can verify the doorbell's connectivity status and replace under warranty if faulty. Most offline issues are network or battery related and user-resolvable.
