Failback Configuration (Advanced Mode Only)
This is used to configure failback, which is the 
ability to go back to a higher priority WAN 
interface if it regains connection to its network. 
Usage: Fail back based on the amount of data 
passed over time. This is a good setting for when 
you have a dual-mode EVDO/WiMAX modem 
and you are going in and out of WiMAX 
coverage. If the router has failed over to EVDO it 
will wait until you have low data usage before 
bringing down the EVDO connection to check if a 
WiMAX connection can be made. 
High (Rate: 80 KB/s. Time Period: 30
seconds.)
Normal (Rate: 20 KB/s. Time Period: 90 seconds.)
Low (Rate: 10 KB/s. Time Period: 240 seconds.)
Custom (Rate range: 1-100 KB/s. Time Period range: 10-300 seconds.)
Time: Fail back only after a set period of time. (Default: 90 seconds. Range: 10-300 seconds.) This is a good setting if 
you have a primary wired WAN connection and only use a modem for failover when your wired connection goes down. 
This ensures that the higher priority interface has remained online for a set period of time before it becomes active (in 
case the connection is dropping in and out, for example). 
Disabled: Deactivate failback mode.
Immediate Mode: Fail back immediately whenever a higher priority interface is plugged in or when there is a priority 
change. Immediate failback returns you to the use of your preferred internet source more quickly which may have 
advantages such as reducing the cost of a failover data plan, but it may cause more interruptions in your network than 
Usage or Time modes.
