Fail Over - Airlink101 AR580W3G User Manual

3-4 Fail Over

WAN failure detection works by detecting the presence of traffic on the 3G modem link. If
the link is idle for too long the router will attempt to ping a target IP address. If the ping
does not reply, the router assumes the link is down and attempts to fail over to ethernet
WAN link.
Here are descriptions of every setup items:
WAN
FailOver (1):
WAN Priority (2):
Idle Timeout
Detect (3):
Note: The router will not connect back to the first priority of Internet connection
once it has already failed over to another one.
Check this box to enable Fail Over function.
Please select the WAN connection priority from the drop-down
menu.
Please input the idle time for detecting the Internet
connection. If the major Internet connection is idle for this amount
of time then the router will send a ping to the target IP Address
you have assigned. If the ping gets a reply, the router will restart
the idle timer, otherwise it will failover to the second priority of
WAN connection.
