Connect Manually allows user to connect to the Internet manually. The Internet
connection will be inactive after it has been inactive for a specified idle time.
When the Network Monitoring feature is enabled, the router uses DNS Query or ICMP to
periodically check the Internet connection state.
Choose 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 the 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.
Check Interval defines the transmitting interval between two DNS Query or ICMP
checking packets.
Check Timeout defines the timeout of each DNS query/ICMP.
Latency Threshold defines the tolerance threshold of responding time.
Fail Threshold specifies the detected disconnection before the router recognizes
the WAN link down status. Enter a number of disconnection times before
disconnection is acknowledged as the threshold.
Target1 (DNS1 set by default) specifies the first target of sending DNS query/ICMP
request.
DNS1: set the primary DNS to be the target.
DNS2: set the secondary DNS to be the target.
Gateway: set the Current gateway to be the target.
Other Host: enter an IP address to be the target.
Target2 (None set by default) specifies the second target of sending DNS
query/ICMP request.
None: to disable Target2.
DNS1: set the primary DNS to be the target.
DNS2: set the secondary DNS to be the target.
Gateway: set the Current gateway to be the target.
Other Host: enter an IP address to be the target.
