Happened again today. Recorded a full session 20-30min without problems from 9:30-10am, but our second set 11am crapped out 10-15min in.
Using a Cisco AE1000 for wireless and have only 1 iPad connected for monitoring. Recording to a Sandisk Ultra 16GB SDHC Class 10 card rated at 30 MB/s

Looking for any suggestions on what to try next? May try removing the USB Wifi stick the next time we try to record a session, or record off a PC since recording directly to the board seems unreliable.
