3-4 FailOver
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 an
Ethernet WAN link.
Below are descriptions of the options:
WAN FailOver (1): Check this box to enable the function.
WAN Priority (2):
Idle Timeout
Detect (3):
Note: The router will not connect back to the first-priority Internet
connection once it has already failed over to another one.
Select the WAN connection priority from the
drop-down menu.
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 fail over to
the second-priority WAN connection.
