iPad and iPhone app unusable

The principle of ScanDisk Connect is basically fine, but useless if the right software is so flawed as for iPad and iPhone. A transfer large amounts of data (for example, vacation videos and images from iPhone / iPad) basically break after some time with error messages. Thus no use for the holidays as a backup.
Some tests showed the following results:
- Is switched WPA, then breaks the connection with larger files understandable and constantly decreasing.
- The WLAN encryption is disabled, does the Media Drive. On holiday but this makes no sense, if the hotel room neighbor can call in on my Media Drive without a password and encryption.
Sandisk has also previously not thought it necessary to make Web access via the 192.168.11.1 with a password "protectable".
