Is there any reason why during the later part of the day some of the iBooks lose the internet connection? >> Several thoughts come to mind: 1. Are the books put to sleep while they are being recharged? 2. Why aren't they plugged into the charger/converter all day long? 3. Are they completely shut down at any time during the day? 4. What is the 1/2 life time period of the TCP/IP address given by your server? Any of the above listed conditions could cause a loss of connection. There are some other reasons for losing connection, but not that I think would exist in a classroom setting (except for student mis-handling of equipment).
