I'm having substantial issues with the card dropping the connection to my iPad 2. Each time I have to open the settings on the iPad 2 and select the "network" that is the Eye-Fi Card. The re-open the app and the images will download.
I've told the network settings to "forget" the usual network I'm logged into. I've changed my body to never auto off. Nothing seems to help.
I've sent a request to the company, not heard back yet.
Also checked for updates on the card and it is current.
