Item Description
Network Monitoring
Configuration When the Network Monitoring feature is enabled, the gateway will
use DNS Query or ICMP to periodically check Internet connection
– connected or disconnected.
Checking Method Select either DNS Query or ICMP Checking to detect WAN link.

With DNS Query , the system checks the connection by
sending DNS Query packets to the destination specified in
Target 1 and Target 2.

With ICMP Checking , the system will check connection by
sending ICMP request packets to the destination specified in
Target 1 and Target 2.
Loading Check Enable Loading Check allows the router to ignore unreturned DNS
Queries or ICMP requests when WAN bandwidth is fully occupied.
This is to prevent false link-down status.
Query Interval Defines the transmitting interval between two DNS Query or ICMP
checking packets.
Latency Threshold Defines the tolerance threshold of responding time.
Fail Threshold Specifies the detected disconnection before the router recognize
the WAN link down status. Enter a number of detecting
