Wi-Fi Information and Troubleshooting Guide

All Blink cameras require a 2.4 GHz Wi-Fi Internet connection. The cameras use Wi-Fi to send images and notifications so you can view them from the Blink app on your mobile device. At minimum, Blink systems need a connection of at least 2 Mbps upload speed.

Wi-Fi is also important for Blink cameras that need to connect to a Sync Module on the same Wi-Fi network. The Sync Module is the hub between the Blink app, Blink Servers and your camera. Without an internet connection, this data exchange is not possible.

The Blink Mini, Wired Floodlight, and Video Doorbell do not require a Sync Module to function, but do require a local Wi-Fi signal.

General Wi-Fi issues

Understanding Wi-Fi and network requirements

Use this article to understand optimum network requirements for your Blink devices.

Wi-Fi Network Requirements

  • 2.4GHz Wi-Fi Network 802.11b/g/n 
  • A high-speed internet connection (DSL, Cable, Fiber) with a minimum upload speed of 2 Mbit/sec.
  • IP Configuration: DHCP 
  • Wi-Fi Security: WEP, WPA, WPA2 with TKIP SSID

Note: Blink does not support satellite internet due to high latency issues.

Things to check first

Start with the following:

  • Verify signal strengths. Blink App > Device Settings > General Settings > Camera to Wi-Fi will show your device's signal strength.
    • Find out more in the Network layout and Connectivity sections below.
  • Power cycle all devices that allow connection to the internet.
  • Verify your internet connection and account are active.

Network layout

Where to place your Sync Module

The Sync Module is the hub between the Blink app, Blink Servers and your camera. Without an internet connection, this data exchange is not possible. 

In a typical situation (single building, no unusually dense construction materials), the Sync Module should be able to communicate with Blink cameras up to 100 ft. (30m) away in any direction. We recommend keeping the Sync Module near your wireless router for best signal strength. For optimum camera and Sync Module usage, three bars of signal strength displaying on the Sync Module screen is ideal.

Examples of less than ideal Sync Module locations:

  • Behind a Television
  • Inside a closed cabinet
  • Directly on top of your Wi-Fi router
  • In a basement

Examples of good Sync Module locations:

  • On a window sill, in a central location between your indoor and outdoor cameras
  • On TV stand or cabinet, and no less than 3 ft. (1m) and no more than 10 ft. (3m) away from your Wi-Fi router
  • Near other equipment that may also be using your Wi-Fi 


Camera connectivity issues with your network

The Blink system relies on having good signal strengths for optimal performance in viewing Live Views, uploading motion clips and for best video quality. It is critical for the cameras to show 3 bars of connectivity to avoid performance issues.

Fewer than 3 bars for each connection can create intermittent issues with the performance of your system. 

In case of any camera issues on a mesh network, rebooting the router should be a first step.

Assuming standard construction techniques (single building, no unusually dense construction materials) the Sync Module should be able to communicate with Blink cameras up to 100 feet (33m) away in any direction. We recommend keeping the Sync Module near your wireless router for best signal strength. 

See the section below to learn about signal strengths and how to check them. You should have three bars of signal connectivity at the Sync Module and each camera, as depicted on the Sync Module screen in the Blink app.

Where to find signal strength in the Blink app

Tap the More iconsettings icon at the bottom right of the device's thumbnail image and select Device Settings. Then tap General Settings.

You will see a Network section. Depending on the type of camera you have, this section can contain:

  • Change Wi-Fi
    • Tapping this allows you to change your device's existing Wi-Fi connection. Use this if you have installed a new router for your network or want to change access points for your devices.
  • Connection to Wi-Fi
    • The icon here represents the strength of your Wi-Fi connection to the camera.
  • Connection to Sync Module
    • The icon here represents the strength of your Sync Module's connection to your network.

Signal types

Its important to note that the cameras use two types of signals for communication:

  • LFR - Low Frequency Radio - is the signal that cameras share with the Sync Module.
  • Wi-Fi (2.4 GHz) - is the frequency that the cameras communicate with your Wi-Fi router on. Blink supports mesh and merged networks with a single SSID but only communicates on the 2.4 GHz band.

How to boost internet signal

One solution, other than moving the camera closer to the Wi-Fi router, is to install a Wi-Fi extender or booster. A newer, more effective solution is called mesh Wi-Fi.

  • Extenders
    A Wi-Fi extender repeats the wireless signal from your router to expand its coverage. Extenders function as a bridge to capture the Wi-Fi from your router and rebroadcast it to areas where the Wi-Fi is weak or nonexistent. This improves the overall Wi-Fi performance and signal strength for all connected devices within range. Learn more about using extenders with Blink cameras.
  • Mesh Wi-Fi
    Mesh networks eliminate connectivity dead zones by blanketing your home in Wi-Fi. They work by allowing different types of devices to chain off each other as nodes in a network, each broadcasting the radio signal further than the last. The typical mesh network includes several nodes, which act like satellites for your network. One of these nodes is a gateway and connects to the internet through your modem. The other nodes communicate to each other and will expand your wireless coverage every time you add a new node. Rather than communicating with a single access point (like a traditional network), each node of a mesh network communicates with the others. This distributes the overall signal strength and Wi-Fi coverage throughout an area.

Troubleshooting your connection

If your connections to either your Wi-Fi or Sync Module are below 2 bars or less, attempt the following troubleshooting steps.

camera settings page update signal strength button

  1. Device placement
    • Move the device closer to the Wi-Fi router and tap Pull to Refresh to check if the bars increase. Repeat until you see improved signal strength.
  2. Check your internet
    • If you haven't already, attempt a power cycle of the Wi-Fi router.
    • Check that your 2.4 GHz Wi-Fi network is functioning normally and that the internet is available.
    • Check that the Wi-Fi network speed is not being reduced by streaming movies and games, or other high bandwidth activities. Two Megabit per second (2 Mb/sec) upload speed (going from your location) must be available to the Blink system at all times. Test your connection by temporarily suspending any streaming of music, movies, video or gaming to prevent consumption of bandwidth.
    • If your Wi-Fi password or network has changed, the Blink system will not function correctly until you update the settings.
  3. Check that the outlet provides power
    • To confirm that power is present to the wall outlet, you can try plugging in a different device or appliance.
    • Some outlets are controlled by a wall switch, check to see if this applies to your outlet.
    • If the wall outlet is not providing power, you can try a different outlet.
    • It is also possible that a circuit breaker has tripped, so you may want to check your electrical distribution panel.
  4. Check that the wall charger provides power
    • If your outlet has power and the camera is not getting power, try to use a different wall charger.
    • Any standard 5 volt USB wall charger should work. 5 volt USB phone chargers are commonly available.
  5. Check the cable
    • It is possible that the USB cable became damaged from being bumped into. The damage may not be visible from outside.
    • You can try the camera's power cable with another device to see if power is present.
    • You can try to use another USB Type A male, to micro-usb Type B male, cable. These are commonly used for charging phones and other devices.

Network frequency

Wi-Fi Router Band Settings

Blink products can only connect to 2.4 GHz (802.11 b/g/n) networks.

The Sync Module will not respond if it has been switched to a 5 GHz network.

What’s the Difference Between 2.4 GHz vs 5 GHz Wi-Fi?

Blink devices cannot connect to a 5 GHz network. The differences between 2.4 GHz and 5 GHz bands are the speed and range of their networks. A 2.4 GHz band transmits farther and can penetrate building materials better with lower power transmission. A 5 GHz band; however, can send more data. 

5 GHz should not be confused with 5G networks that mobile devices use for data transmission.

Dual-Band Routers

A dual-band router is any wireless internet router that sends out a signal on both 2.4GHz and 5GHz frequencies. Routers have features that vary based on manufacturer and model. Most dual-band routers automatically broadcast on both bands without any additional configuration, which is why it may not be obvious there are two bands.

Which Band is Better?

The main differences between 2.4GHz and 5GHz bands are the speed and range of their networks. A 2.4GHz band transmits farther and can penetrate building materials better with lower power transmission. A 5GHz band; however, can send more data. 5GHz should not be confused with 5G networks that mobile devices use for data transmission.

Many other devices commonly found in homes, such as microwave ovens and garage door openers, also operate on the 2.4GHz band. This can cause interference and reduce speeds. In addition, placing your devices behind dense building materials such as brick, stone, concrete, steel, and aluminum can interfere with signal strength, even when connecting on 2.4GHz.

Band Merging

With the technological advancement of routers, "band steering" is becoming more common. Routers with this feature use the same Wi-Fi network name (SSID) and password for both 2.4GHz and 5GHz bands, allowing you to join a single network and receive the advantages of both frequencies.

Note: Blink devices only connect to 2.4GHz bands, even when bands are merged on your router.



  1. Often, when adding a camera or Sync Module to your Blink system, the password is mistyped. Try carefully re-entering your password. If you continue to receive the "Incorrect password for Your W-Fi" message, try the next steps.
  2. Verify the password by checking if it's written on a sticker located on your router. 
  3. Try forgetting the Wi-Fi network on your mobile device's network settings, and then reconnect to it. If you can successfully reconnect using this method, your password is correct.

Router settings

Make sure that your router is not blocking access to the Sync Module. This can happen if you are alerted that a device is attempting access but the name is not familiar. Blink devices are sometimes identified by their radio chip instead of the Blink product name.

Disable VPN

Do you use a virtual private network (VPN) on your mobile device?  If so, please disable the VPN before you set up Blink devices. You can enable your VPN after you complete setup.

If you're continuing to have issues with VPN after setup, make sure your VPN server is in the same time zone as your device.

Important information to discuss with your Internet Service Provider (ISP)

We suggest speaking with your ISP to discuss your home network capabilities. Here is a guide for reviewing your network setup with your ISP.

  • Upload speed - The Blink system requires a consistent minimum upload speed of 2Mbps per camera. Any result lower than 2Mbps may cause latency and/or issues establishing or maintaining connection.
  • Network congestion - The more devices in your home use Wi-Fi, the more they will be sharing your network's bandwidth. You can disable the Wi-Fi setting for non-Blink devices not in use and reenable it as needed.
  • Old routing equipment - What is the age/model of your router? We recommend a router model less than 5 years old to ensure it supports the latest technology. If you're renting network equipment, your ISP may be able to provide you with an upgraded model at no additional cost.
  • Packet loss - This means bits of information are being dropped when communicated over the network. This can cause communication failure from your device to your router or your mobile device to your router. Packet loss can occur within your home (device to router) and/or within your connection from your router to your ISP's server.
  • Privacy settings/Parental Controls/Firewalls - Network security is important. Ensure these settings are set up so they do not interfere with your ability to connect to your connection to your Blink system. Ensure that each individual Blink device is allowed to establish its own connection. Tip: you can white-list your Blink device's individual MAC addresses. If you are unsure how to do so, check with your ISP.
  • Duplicate SSIDs - When two networks in the same location have the same SSID/name, your Blink system may try to connect to the wrong one. This other SSID may be in a different location that is too far for reliable connectivity or may be and incompatible network. Ensure you are attempting to connect to the appropriate SSID.

Wi-Fi 6 (802.11ax) compatibility

Wi-Fi 6, also known as Wi-Fi 802.11ax is a new wireless technology being implemented in new routers.

Blink devices (Camera and Sync Module) require the use of an 802.11b/g/n network. Blink devices do not support the upcoming standard Wi-Fi 6 (802.11ax), but those new routers are backwards compatible with 802.11b/g/n, so Blink will continue to function as it does today.

Mobile Devices Not Connecting to Wi-Fi

If your mobile device has no connection to your Wi-Fi network, you will not be able to add a Sync Module or Blink camera. However, if you have Wi-Fi off, the Blink app attempts to turn Wi-Fi on in the install process.

After a device is added to your Blink system, use the Blink app for all other functions on mobile data alone, or on another Wi-Fi network. Learn more about how to set up and add devices to a Blink system. Here's some tips to help get your device connected to your Wi-Fi network.
  • Make sure your device’s Wi-Fi is turned on and not in airplane mode. Depending on your device, Wi-Fi settings can be usually located within your Settings app or by swiping down from the top or up from the bottom of your screen.
  • Restart your device, or try switching the Wi-Fi setting off and on again to establish a connection.
  • Make sure your mobile device is within range of your router or access point.
  • Check that your router and any access points are powered on. Restarting your Wi-Fi router may also resolve this issue.
  • Check that other devices are able to connect and function properly on your Wi-Fi. This will rule out any network issues.
  • Make sure you have the latest OS installed on your device.
  • Turn off Location Services which could cause connectivity issues in some cases.

  1. Often, when adding a camera or Sync Module to your Blink system, the password is mistyped. Try carefully re-entering your password. If you continue to receive the "Incorrect password for Your Wi-Fi" message, try the next steps.
  2. Verify the password by checking if it's written on a sticker located on your router. 
  3. Try forgetting the Wi-Fi network on your mobile device's network settings, and then reconnect to it. If you can successfully reconnect using this method, it will confirm you are using the correct password.

Other troubleshooting

Working with dual band networks

Many modern routers are dual band, and can broadcast both network frequencies - 2.4GHz and 5GHz. This can sometimes lead to issues when connecting to other smart devices in the home. For example, if your mobile device is connected to the 5GHz network and you're trying to set up a device that needs to connect to a 2.4GHz network, errors may arise, including incorrect password errors.

If your router is dual band, it may be necessary to temporarily disable the 5GHz band in order to connect exclusively to the 2.4GHz band and then add your Blink devices. If you're unable to do this or still receiving errors, contact your ISP or router manufacturer.


What is the Blink Wi-Fi Network?

The Blink Wi-Fi network is a temporary wireless signal used to connect Blink devices to your mobile device. When adding a Sync Module, Mini, Video Doorbell, or Wired Floodlight Camera, the Blink app will prompt you to connect to the temporary Blink Wi-Fi network. This network is named “BLINK-" followed by the last four digits of the device's serial number. 

The Sync Module manages communications between your wireless cameras and Blink secure servers. The Blink Mini, Video Doorbell, and Wired Floodlight do not require a Sync Module for those communications.

Sync Module Example

Mini Example

Doorbell Example

You can safely connect your mobile device to your local "BLINK-XXXX" temporary Wi-Fi connection. If you encounter problems connecting to your local Blink Wi-Fi, make sure you have the Blink app Local Network (iOS) or Location (Android) permissions enabled on your mobile device. See the links below for more information.

Device issues

Blink Mini Camera Offline

  Note: We’ve enhanced the design of the Blink app. If the steps listed below in this article do not match your current app (6.30.0 or higher), you can view the previous design.

If you receive a Camera is offline message on your Blink app home screen, it means the Blink servers lost communication with your Mini camera. This will normally fix itself when the network comes back up, or when there is less traffic on the Wi-Fi network. When your camera comes back online, the message will disappear.

Most often, disconnected or slow internet makes the Mini camera lose contact. Most internet providers provide downloads to your location much faster than uploads from your location. If there is a sudden jump in the data being used, the Mini camera may miss a check-in and the offline message may appear.

If your camera keeps disconnecting even when power and Wi-Fi internet are steady, please contact Blink support.

Troubleshoot Mini camera offline message

Check Power

The Blink Mini compact camera is powered by direct connection to a USB standard power adapter instead of batteries. To function, the power cord must be reliably connected to a 5 volt 1 Amp power source, and the molded micro-USB connector must be fully inserted into the camera.

Check Internet

To send you images and sounds, the Mini camera needs a 2.4 GHz Wi-Fi internet connection with upload speeds (going out from your network) at least two megabits per second (2 Mb/sec) at all times, including when others are on the same internet connection.

When you tap the alert shown in the app home screen, a Camera Offline screen provides helpful tips. The first, is to check the Wi-Fi internet and the power supply, then check the camera power connection.


Troubleshooting Wi-Fi

  1. Check Wi-Fi. Ensure that you can connect to the internet, and that the password has not been changed. If the password has been changed, refer to the next step.
    Rebooting the Wi-Fi router is often very effective to resolve Blink connectivity issues.
    If you have rebooted your router and Blink does not connect after 3 minutes, continue.
  2. Check your password. If the password is changed, or if you wish to use a different Wi-Fi network, tap the Change Wi-Fi button:     Change Wi-Fi     and follow the instructions.
    If the password or network have not changed, continue.
  3. To repeat the camera installation process, tap the Delete Camera button:    Delete Camera   and follow the instructions.

If these steps do not reconnect your camera, please contact Blink support.
