The default interval between the two connection detection is 3 minutes, and the range is
from 1 to 3 minutes. Once Internet connection is disconnected, the system automatically
connects Internet via 3.5G adapter. If 3.5G signal is not available, it starts to search
downward for 3/2.75/2.5G signals until none existed. Please check to activate or not.

This feature requires user to enter user name, password and SIM PIN etc.; also it is
working as mutual backup for other 4 WAN Types. That is, setting up the interval time to
auto detect whether the Internet connection is lost or not. If yes, the system immediately
switches to 3.5G Internet connection until the original connection is back during the next
detection.
