When your doorbell is not connected to the internet, a "Doorbell Offline" message appears in the Blink app as shown below. If your Wi-Fi network is slow or stops randomly, it can help to reset your Wi-Fi router as a first step. When your doorbell connects to the internet again, the notice is removed.
To connect your doorbell to Wi-Fi, continue reading.
When you tap the "Doorbell Offline" message, we show you two ways to get your doorbell back online. You can change/reset the Wi-Fi network of your doorbell, or delete the doorbell and add it again. Both options include removing the doorbell from its back plate.
To "Change Wi-Fi", you disconnect the doorbell and repeat the steps to connect your network.
Change Wi-Fi of a Blink Video Doorbell
To connect your Blink Video Doorbell to a new Wi-Fi network, or reconnect to your existing network, you will need to physically access the doorbell and follow the Blink app instructions.
If you are seeing a "Doorbell Offline" message, tap the banner and you will be guided to change the Wi-fi network.
Electric Shock Risk: If your doorbell is connected to powered wiring, there is a risk of electric shock when the doorbell is removed form its back plate. Live wires can cause injury if you connect them together by touching with skin, or a conductive object like a steel screwdriver.
To change doorbell Wi-Fi
If your doorbell has become disconnected because the Wi-Fi network is different, or if you need to move to a new network, tap the doorbell's Settings icon 
on the home screen.
Tap "Change Wi-Fi" and complete the steps.
For safety, if you have connected powered wiring to your doorbell, you should turn off all power to the circuit. Tap "Continue" after you turn off power to the chime, or if you did not connect powered wiring.
Then you are prompted to remove the doorbell from its back plate with the opening key.
When the doorbell is removed, tap "Continue", and the next screen shows where to find the Reset button.
Press the reset button for your doorbell
If you can see or touch the surface of the batteries when they are in place, the reset button is a raised point on a tab, aligned between the batteries and just above. If you have a battery cover, the reset button is a soft plastic disc above the wire terminal screws.
| Batteries are open to view | With battery cover |
| Hold the reset button for 5 seconds, then turn the doorbell over to view the front face and wait for the red LED to flash at the top of the ring surrounding the button. | Hold the reset button until green and blue LED's light up followed by flashing red, at the top of the ring surround. |

When the LED pattern is correct, tap the "Discover Device" button.
Not Blinking Red?
If the red LED is not flashing after 30 seconds, tap the "Not Blinking Red?" link.
- Remove the batteries for ten seconds, replace them, wait for the red LED.
(if the doorbell is already installed the red LED does not flash) - Make sure the batteries are fresh.
- Press and hold the reset button until the LED flashes red.
Tap "Contact Customer Support" if your doorbell still does not display the flashing red light after following the instructions above.

Doorbell General Troubleshooting steps
- Make sure that your Wi-Fi is powered on and working. The Blink doorbell requires Wi-Fi to communicate. A router reset can resolve problems with connectivity.
- Make sure the doorbell has fresh batteries. In Event Response, the batteries may run out faster than when the doorbell is connected to powered wiring, or a Sync Module.
What if my Doorbell connects to a Sync Module?
When your doorbell is connected to a system managed by a Sync Module and it stops being detected, you receive a notification in the app and an email (if you have email notifications selected). Click to learn more about notifications settings.
Here are some troubleshooting steps to get the doorbell quickly back online.
- Use the included key to unlock the doorbell from its mount.
- Do a 'Power Reset' of the doorbell by removing the batteries for 5 seconds and then re-inserting them. Wait for another 30 seconds, then you can test the doorbell to see if it is connected.
- Move the Sync Module closer to the doorbell. It is possible that the network is not able to communicate fully.
- Replace the batteries with 2, new, size AA 1.5 volt Lithium non-rechargeable batteries.
Increased use, and extended Live View sessions may use batteries faster than expected.
If these steps do not get your doorbell connect to the Blink servers, please contact Customer Support so we can troubleshoot with you directly.
What if my Doorbell connects to wiring only?
When we detect that the doorbell is no longer online, you receive a message in the app and by email, that reads: "The connection to your doorbell camera seems to have been dropped. Please check that your Wi-Fi internet and power supply are working to your Blink Doorbell."
Here are some troubleshooting steps to fix this message.
- Please check that your doorbell is attached to the wall plate and that the main circuit breaker is turned back on.
- Sometimes home wiring may be old or not working. This device does not work with broken wiring and you may need a professional electrician for advice about your home electrical environment. Please follow your local regulations.
- Make sure that you have fresh batteries. Two, size AA 1.5 volt Lithium non-rechargeable batteries are needed to power the doorbell at all times. Adding the doorbell to a Sync Module system increases average battery life to 2 years.
If the above steps don't resolve the issue, please contact Customer Support.
What if my doorbell is in Event Response?
When the Blink Video Doorbell is not connected to a Sync Module or wiring, it is in "Event Response". Meaning, that all communication with the Blink servers is powered by the Doorbell alone.
To save batteries, the doorbell checks in once in every 24 hour period. It could take as long as 48 hours for the doorbell to be considered offline when it is in Event Response.
If we detect that your doorbell is not communicating, we send an alert to the app and to the email address registered for your account, that reads: "The connection to your camera seems to have been dropped. Please check that your Wi-Fi internet and power supply are working and that the camera is attached to your wall plate and that your breaker is on."
To troubleshoot:
- Make sure that your Wi-Fi is powered on and working. The Blink doorbell requires Wi-Fi to communicate.
- Make sure the doorbell has fresh batteries. In Event Response, the batteries may run out faster than when the doorbell is connected to powered wiring or a Sync Module.
- After installation, it is possible that the power mains was not turned back on at the circuit breaker. Please make sure that the power is on.
