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.

Password

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 device. 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, 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.

Wi-Fi Password Troubleshooting

If you encounter an "Incorrect Password for Your Wi-Fi" alert while adding a camera or Sync Module to your Blink app, attempt the following troubleshooting steps:

1. Re-enter Wi-Fi Password: Double-check that you've entered the correct Wi-Fi password, and try again. If the "Incorrect Password for Your Wi-Fi" alert persists, proceed with the next steps.
2. Check Password on Router: Check your router for a sticker containing the Wi-Fi password. Keep in mind, some routers might not have this sticker.
3. Forget and Reconnect Wi-Fi Network: On your mobile device, go to network settings and choose to forget the Wi-Fi network. Then, try connecting to it again. If you can reconnect successfully, it means the password is correct.

   • Android users: Remove saved networks

Special Characters in Your Wi-Fi Password

Using special characters (e.g., *, @, $, #) in your Wi-Fi password can sometimes create challenges during the initial setup of your Blink device. If you encounter any problems after confirming that your Wi-Fi password is correct, as outlined in the steps above, attempt the following troubleshooting steps:

1. Temporarily change your Wi-Fi password: Temporarily change your Wi-Fi password, ensuring it does not include any special characters.
2. Create a temporary guest network: Create a temporary guest network specifically for setting up your Blink device. After successfully setting up and connecting your Blink device to the internet, you can remove the temporary or guest network without impacting the device's functionality.

If you change your Wi-Fi password at any point after the initial setup, you must also update the password on your Blink devices and any other devices that connect to your Wi-Fi network.

When adding a Sync Module, Mini, Video Doorbell, or Wired Floodlight Camera, you will be prompted to connect your Blink app to the temporary Wi-Fi network. It is named “BLINK-" followed by the last four digits of the device's serial number. 

The Sync Module manages communications between your Blink devices and our secure servers; therefore your camera needs to connect to its local Wi-Fi. The Blink Mini, Video Doorbell, and Wired Floodlight do not require Sync Modules for those communications, which is why they broadcast their own local Wi-Fi connections.

It is completely safe to connect your mobile device to your local "BLINK-XXXX" Wi-Fi connection and there are no security issues. If you encounter any 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.

iOS

Learn more about enabling Local Network for your Blink app on your iOS device.

Android

Learn more about changing the Blink app permissions on your Android device.

The camera in the Wired Floodlight Camera has a reset button at the top, which is not visible from the ground when it's mounted. This button can put the camera in setup mode to be added to a new or existing system or to a new Wi-Fi network. 

• Short press (less than 5 seconds) resets it and resolves most setup issues. 
• Long press puts the camera into setup mode. This also erases your Wi-Fi credentials; therefore, you need to enter your network name and password again to reconnect to your Internet.

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 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.
