PoE AP Router

Set up “Ethernet Common Configuration”
Ethernet WAN Common Configuration
Item Value setting Description
Connection Control
A Must filled setting
There are three connection modes.

Auto ‐ reconnect enables the router to always keep the Internet
connection on.

Connect ‐ on ‐ demand enables the router to automatically re ‐
establish Internet connection as soon as user attempts to access
the Internet. Internet connection will be disconnected when it has
been inactive for a specified idle time.

Connect Manually allows user to connect to Internet manually .
Internet connection will be inactive after it has been inactive for
specified idle time.
Maximum Idle Time
1. An Optional setting
2. By default 600
seconds is filled ‐ in
Specify the maximum Idle time setting to disconnect the internet
connection when the connection idle timed out.
Value Range : 300 ~ 86400.
Note : This field is available only when Connect ‐ on ‐ demand or Connect
Manually is selected as the connection control scheme.
MTU
1. A Must filled
setting
2. Auto (value zero)
is set by default
3. Manual set range
1200~1500
MTU refers to Maximum Transmission Unit. It specifies the largest packet
size permitted for Internet transmission.
When set to Auto (value ‘0’), the router selects the best MTU for best
Internet connection performance.
NAT
1. An optional setting
2. NAT is enabled by
default
Enable NAT to apply NAT on the WAN connection. Uncheck the box to
disable NAT function.
Network Monitoring
1. An optional setting
2. Enabled by default
When the Network Monitoring feature is enabled, the gateway will use
DNS Query or ICMP to periodically check Internet connection –connected
or disconnected.

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 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
recognize the WAN link down status. Enter a number of detecting
disconnection times to be the threshold before disconnection is
acknowledged.

Target1 ( DNS1 set by default ) specifies the first target of sending DNS
