Solution
This message is displayed if there is no response when connecting to a computer via Wi-Fi. Possible causes for this message include the following:
- The computer is not turned on, or is in sleep mode.
- There is no access point (Wi-Fi router) nearby.
- The access point (Wi-Fi router) is not turned on. An error occurs.
- Security software settings are blocking transmission.
- The computer and camera are not connected to the same network (SSID).
- "Wi-Fi connection setup" has not been configured.
- The camera driver is not installed in the computer.
- There is a problem with the computer (Windows).
Check the following details in order.
If the computer is in sleep mode, the camera cannot connect to the computer. Check what mode the computer is in.
Signal reception may be poor if the access point (Wi-Fi router) is too far away, or if there are walls, doors, or other obstacles between the access point and the camera. Move the camera as close as possible to the access point to make a connection. Also, confirm that an error has not occurred at the access point. For details about access point errors, contact the manufacturer of the access point.
Some security software settings will block connections. Temporarily disable the security software and then try connecting again. For details about how to temporarily disable security software, contact the manufacturer of the software.
If the computer and camera are connected to access points (Wi-Fi routers) with different SSID, you cannot save images to the computer. Confirm that the computer and camera are connected to the same SSID.
If you have not done so already, configure "Wi-Fi connection setup".
