When your Blink sync module flashes a green light, it can’t connect with the cameras and other devices.
The malfunction renders your security system useless and exposes your property to security risks.
This article discusses why your blink sync module flashes a green light and how you can fix the problem.
Why Is My Blink Sync Module Blinking Green?
Reason 1: Internet connection problem
The major cause of your Blink camera sync module blinking green light is an internet connection problem.
Your Blink sync module requires strong internet access to link your Blink cameras with the cloud servers. This enables you to access the paired devices through the app for alerts, notifications, live feeds, etc.
Disconnection of your internet connection is why your Blink sync module flashes a green light indicator.
It means an unstable or slow Internet connection, and the internet provider is experiencing difficulties.
You’ll encounter this problem whenever your Sync module can’t connect to your Internet connection or router.
Also, this problem can occur when you recently changed your Wi-Fi password.
How to fix: Reboot the internet connection
- Check if your Wi-Fi connection is functioning properly.
- Check your internet speed on your computer or mobile on which your Wi-Fi is connected.
- If the connection is slow or unstable, reboot your internet router. To do this, unplug the router from the power source for some three seconds, then plug it back in. This will get your internet back up and running.
- If the blinking green light problem is still showing, contact your internet provider to know the cause of the Wi-Fi interruption.
Reason 2: Server outage
If the problem continues, it means the issue could be caused by a server outage.
Whenever there are problems with Blink security servers and server outages, your Blink Sync module may experience the blinking green light issue.
Sometimes, when the Blink servers undergo maintenance or an upgrade, this process might cause your Blink Sync module to flash a green light.
Whenever the Blink data servers are down, the Sync module can’t connect to the internet, which causes the green light to flash.
How to fix: Troubleshot Blink servers
- Check the Blink server status to see if there is an outage.
- To know if the Blink servers are down, check their status on the Down Detector website.
- Ensure the Blink cameras are connected to a reliable and strong Wi-Fi network. Ensure the Wi-Fi signal is strong, and the cameras work properly.
- Check if the flashing green light problem is resolved.
- If not, try resetting your cameras by unplugging them and plugging them back into the power.
- If the problem still happens, try moving your router closer to the sync module or the cameras.
- If these solutions fail to work, contact Blink Support for more assistance.
Reason 3: Power issues
The sync module uses power for its functionality and is connected to your Wi-Fi network to carry out activity for Blink devices.
Sometimes, prolonged usage can lead to errors and bugs affecting its operations, including the green blinking light issue.
Sometimes, connectivity issues and a power outage or surge in your home can impact the device’s operations, leading to the green flashing LED issue.
It is, therefore, necessary to periodically refresh the Sync Module.
How to fix: Power cycle the Sync Module and router:
- Conduct a power cycle both to the Sync Module and the router.
- Unplug the Sync Module’s power adapter from the power outlet.
- Wait for about 10 seconds. Plug the Sync Module’s power adapter back into the power outlet.
- Wait for the Sync Module to power up and reconnect to the network.
- Do the same process to the router.
- Power cycling helps reset the devices to ensure they work properly and establish a new connection with your Wi-Fi channel.
- Check if the green light stabilizes.
Reason 4: Interference in wireless devices
Signal interference from physical obstructions or other electronic devices can also cause the blinking green light problem.
This especially happens when other devices that compete for the same 2.4 GHz Wi-Fi frequencies can interfere with your Wi-Fi connection.
The other wireless devices (such as baby monitors, wireless headsets, Bluetooth microphones, speakers, microwaves, cordless phones, and others) can cause interference that prevents the blink sync module from causing the flash green light problem.
When this interference happens, your sync module may blink the green light, meaning that the device is not working properly.
Also, if your Wi-Fi signal goes through furniture and thick walls, your Wi-Fi signal strength could be affected.
How to fix: Reduce the number of devices connected.
- You can disconnect unnecessary devices that you are not using.
- Put your router in a strategic location so that the Wi-Fi signal doesn’t have to go through an excessive number of furniture and walls.
- Buy Wi-Fi extenders to help amplify Wi-Fi connection in weak spots and dead zones in your house.
Reason 5: Far distance
If your router is far away from your Blink sync module or the cameras, the devices might have problems connecting to the internet.
This could be why your Sync module is experiencing a flashing green light problem.
The Module relies on strong signals to communicate with the cameras. But when they’re too far apart, the signals weaken.
Also, the distance between the Blink sync module and the cameras is an important factor in keeping your sync module online all the time.
If the distance between the Blink cameras and the Sync module is too far, the Module will keep going offline.
How to fix: Put the router and the Sync module in a central location
- Place your Blink cameras within an average signal range of 100 feet from the Sync Module. Anything beyond that will affect performance.
- Like any other device, putting your Sync Module behind dense building materials or with multiple walls between it and the cameras can interfere with its signal strength.
- Install your Sync Module in a central location between your Wi-Fi router and your camera for best results.
- Avoid using virtual private networks (VPNs) as they cause an interruption in connectivity.
- Consider purchasing a new router to help provide the signal strength you need.
Reason 6: Software issues
If you are still struggling with the sync module green light problem, software bugs could be in the Module.
Various software problems can cause this blinking.
The blinking issue is normally caused by a software issue, which glitches in apps or software bugs can cause.
If the software on your Blink cameras or the Module is outdated or corrupted, the sync module may start the flashing green light problem.
Software or app bugs can sometimes cause communication errors or pairing issues between the Module, the cameras, the servers, and the app.
How to fix: Conduct a factory reset
- Ensure proper Wi-Fi network and connectivity between the router, Sync Module, the cameras, and the phone. Also, check the app settings.
- Perform a factory reset to the Module to clear software glitches. The reset will remove the software bug and resolve the blinking green light problem from your Module.
- Ensure that the app, the servers, and all cameras have the latest version and are compatible with the module software.
- If the issue isn’t resolved, move to the next step.
Reason 7: Hardware errors
Sometimes, hardware issues like damaged cables or a faulty one can also lead to the green light flashing.
A malfunctioning component inside the Module is one of the common hardware errors.
Any interruption in the system that affects the performance of the Sync module. Whenever this occurs, the sync module can blink green light and stop cooperating with its wireless cameras.
Sometimes, increasing hot temperatures can cause the hardware to act and shut down itself to prevent damage.
Hardware errors can also arise because of wear and tear or manufacturing defects. If the situation reaches this point, you’ll need to consider a replacement.
How to fix: Replace the Sync module
- Check the hardware and cables for any visible damage.
- If you notice any defects, get a replacement of the cables or contact Blink for assistance.
- In case of damage, consider a new replacement.
- If the problem remains unaddressed, contact Blink technical support for further help.
