WAN - Wide Area Network

WAN refers to your Wide Area Network connection, i.e. your router's connection to your ISP and the
Internet. Here are the items within the WAN section:

WAN Interface

The factory default has the Connection Mode as ADSL and the Protocol as PPPoE.
WAN Connection-ADSL Mode
Main Port: User can select either "ADSL" or "3G" mode.
Failover / Failback: Set Enable to trigger ADSL / 3G failover / failback function ready.
Note: If 3G is set for main port, then there can be no option for failover/failback.
Backup Port: It links to backup port configuration page. It is necessary to configure it when
Failover/Failback be set.
Connectivity Decision: Set how many times of probing failed to switch backup port.
Failover Probe Cycle: Set the time duration for the Failover Probe Cycle to determine when
the router will switch to the backup connection (backup port) once the main connection (main
port) fails.
Note: The time set is for each probe cycle, but the decision to change to the backup port is
determined by Probe Cycle duration multiplied by connection Decision amount (e.g. From the image
above it will be 60 seconds multiplied by 5 consecutive fails).
Failback Probe Cycle: Set the time duration for the Failback Probe Cycle to determine when
the router will switch back to the main connection (main port) from the backup connection
(backup port) once the main connection is communicating again.
Note: The time set is for each probe cycle, but the decision to change to the backup port is
determined by Probe Cycle duration multiplied by Connection Decision amount (e.g. From the image
above it will be 60 seconds multiplied by 5 consecutive fails).
Detect Rule:
Rule 1. ADSL Down
Rule 2. Ping Fail
No Ping: It will not send any ping packet to determine the connection. It means to disable
the ping fail detection.
Ping Gateway: It will send ping packet to gateway and wait response from gateway in
every "Probe Cycle".
Ping Host: It will send ping packet to specific host and wait response in every "Probe
