 IP Address: The default IP address of the device is
192.168.1.1.
 Subnet Mask: The combination of the subnet mask and
IP address enables the flexible sub netting. By default,
the subnet mask is 255.255.255.0.
 DHCP Server: It is used to assign IP addresses
dynamically. If the DHCP server is Enabled, it can
automatically assign IP addresses for PCs. It is
recommended to select Enabled for the DHCP server.
 DHCP Lease Time: The DHCP server automatically
assigns an IP address to each device connected to the
network. When the leased time expires, the DHCP
server checks whether the device is connected to the
network. If the device is disconnected from the network,
the server assigns the IP address to another device.
Thus, the IP address is not wasted.
 IP Pool Range: It is used to define the IP address range
that the host can use during the IP address assignment.
For example, in the network segment 192.168.1.0/24,
the default IP address of the device is 192.168.1.1. The
host IP address can range from 192.168.1.2 to
192.168.1.254. The minimum range is a single IP
address.
Note
 The Start IP Address must be smaller than or
equal to the End IP Address.
 If the DHCP Server is Enabled, the
configurations of Start IP Address, End IP
address, and DHCP Lease Time are valid;
otherwise, you cannot configure them.

accessing the WLAN must use the WEP to authenticate.

 WEP



Wireless Equivalent Privacy (WEP) is a 64-bit or 128-bit data
encryption method. The 128-bit WEP encryption provides
higher security level.
WEP Key 1~4 : You can enter 5 ASCII characters or
10-character hexadecimal numeral to form a 64-bit key. You
can also enter 13 ASCII characters or 26-character
hexadecimal numeral to form a 128-bit key.
Default Key: Select from the drop-down list the WEP key
which will be in use.
hexadecimal value contains numbers of 0-9 and characters
of A-F. For example, you can enter the ASCII value of
1234abcde as the key.
Key Renewal Interval: It is used to set how long a network
key is dynamically changed. By default, it is 3600.
Access Policy
Also known as WLAN MAC Filter function. You can
control and manage the clients accessing the WLAN,
and improve the WLAN security performance.
 Policy

The following table shows the Policy type:
 WPA-PSK/WPA2-PSK
Policy
Description

Disable
The MAC address filter function is
disabled.
The clients with addresses in the MAC
Addresses list are allowed to connect

 Data Beacon Rate (DTIM)


Enter MAC addresses in the list. The device can perform the
access control over the clients whose MAC addresses are in
the list.
Advanced Settings
Click Advanced Settings to make detailed settings for
the Wireless. Advanced Setup includes items that are
not available from the Basic Settings page, such as
Beacon Interval, Control Tx Rates and Basic Data
Rates.
 BG Protection Mode

Default value is Auto. You can select the other options
including On and Off. The BG protection technology is
CTS-To-Self. It will try to reserve the throughput for 11g
clients from 11b clients connecting to the device as AP mode.
 Fragment Threshold

16
Beacons are the packets sending by Access point to
synchronize the wireless network. The beacon interval is the
time interval between beacons sending by this unit in AP or
AP+WDS mode. The default and recommended beacon
interval is 100 milliseconds.
The fragmentation threshold determines the size at which
packets are fragmented (sent as several pieces instead of as
one block). Use a low setting in areas where communication
is poor or where there is a great deal of radio interference.
This function will help you to improve the network
performance.
 RTS Threshold

 Beacon Interval

This is the Delivery Traffic Indication Map. It is used to alert
the clients that multicast and broadcast packets buffered at
the AP will be transmitted immediately after the transmission
of this beacon frame. You can change the value from 1 to 255.
The AP will check the buffered data according to this value.
For example, selecting “1” means to check the buffered
data at every beacon.
The RTS threshold determines the packet size at which the
radio issues a request to send (RTS) before sending the
packet. A low RTS Threshold setting can be useful in areas
where many client devices are associating with the device, or
in areas where the clients are far apart and can detect only
the device and not each other. You can enter a setting
ranging from 0 to 2347 bytes.
 TX Power

The default TX power is 100%. In case of shortening the
distance and the coverage of the wireless network, input a
smaller value to reduce the radio transmission power. For
example, input 80 to apply 80% Tx power.
‹ Country Code
It is used to identify the country or district. Different countries
or districts have different standards on channel usage.
Choose None to make maximum number of channel
available for use
Channel selection must be limited for devices marketed in the
US/Canada to channel 1 ~ 11.
Country code selection feature must be disabled (firmware)
for devices marketed to the US/Canada
