When an Eye-Fi Card is used in the Canon PowerShot G1 X, the camera automatically disables the Eye-Fi cards wifi when the shutter is pressed. Once a photo has been taken, the camera then re-enables wifi on the Eye-Fi card. This has the following effect:
If you are transferring via Direct Mode your connection will be lost and your Eye-Fi X2 card will automatically restart the Direct Mode sequence.
If you are transferring via wifi your connection will temporarily be lost and the Eye-Fi card will automatically reconnect to the network.
We apologize for this user experience and are working with Canon to change this behavior.
