Ch 2. First Time Configuration
Before Start to Configure
There are two ways to configure the device, one is through web-browser, and the other is
through Secure Shell CLI interface. To access the configuration interfaces, make sure
you are using a computer connected to the same network as the device. The default IP
address of the device is 192.168.2.254, and the subnet-mask is 255.255.255.0.
The device has three operation modes (Router/Bridge/WISP). In bridge mode, also
known as AP Client, you can access the device by both WLAN (Wireless Local Area
Network) and wired LAN. And in router/WISP modes, the device can be accessed by
both WLAN and WAN. The default IP addresses for the device are 192.168.2.254(for
17
LAN), 172.1.1.1(for WAN), so you need to make sure the IP address of your PC is in the
same subnet as the device, such as 192.168.2.X (for LAN), 172.1.1.X (for WAN).
Please note that the DHCP server inside the device is default to up and running. Do not
have multiple DHCP servers in your network environment, otherwise it will cause
abnormal situation.
We also provide an auto-discovery tool which is for finding out the IP of the device. In
case, you’ve forgot the IP of the device or the IP of the device has been changed, you
can use the tool to find out the IP of the device even your PC is not in the same subnet as
the device is.
Knowing the Network Application
The device can act as the following roles, and it supports WDS (Wireless Distribution
System) function.
Access Point
WDS (Wireless Repeater)
Bridge/Router
WISP
AP Client
The device provides 3 different operation modes and the wireless radio of device can act
as AP/Client/WDS. The operation mode is about the communication mechanism
between the wired Ethernet NIC and wireless NIC, the following is the types of operation
mode.
Router
The wired Ethernet (WAN) port is used to connect with ADSL/Cable modem and the
wireless NIC is used for your private WLAN. The NAT is existed between the 2 NIC and
all the wireless clients share the same public IP address through the WAN port to ISP.
The default IP configuration for WAN port is static IP. You can access the web server of
device through the default WAN IP address 172.1.1.1 and modify the setting base on
your ISP requirement.
Bridge
The wired Ethernet and wireless NIC are bridged together. Once the mode is selected, all
the WAN related functions will be disabled.
WISP (Wireless ISP)
This mode can let you access the AP of your wireless ISP and share the same public IP
address from your ISP to the PCs connecting with the wired Ethernet port of the device.
18
To use this mode, first you must set the wireless radio to be client mode and connect to
the AP of your ISP then you can configure the WAN IP configuration to meet your ISP
requirement.
The wireless radio of the device acts as the following roles.
AP (Access Point)
The wireless radio of device serves as communications “hub” for wireless clients and
provides a connection to a wired LAN.
AP Client
This mode provides the capability to connect with the other AP using
infrastructure/Ad-hoc networking types. With bridge operation mode, you can directly
connect the wired Ethernet port to your PC and the device becomes a wireless adapter.
And with WISP operation mode, you can connect the wired Ethernet port to a hub/switch
and all the PCs connecting with hub/switch can share the same public IP address from
your ISP.
WDS (Wireless Distribution System)
This mode serves as a wireless repeater; the device forwards the packets to another AP
with WDS function. When this mode is selected, all the wireless clients can’t survey and
connect to the device. The device only allows the WDS connection.
WDS+AP
This mode combines WDS plus AP modes, it not only allows WDS connections but also
the wireless clients can survey and connect to the device.
The following table shows the supporting combination of operation and wireless radio
modes.

REMARK
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1 through 11.
22
Advanced Settings
These settings are only for more technically advanced users who have sufficient
knowledge about wireless LAN. These settings should not be changed unless you
know what effect the changes will have on your device. The default setting is optimized
for the normal operation. For specific application, setting configuration will required
highly attention to reach optimistic condition.
Note：
Any unreasonable value change to default setting will reduce the
throughput of the device.
23
Authentication Type
The device supports two Authentication Types “Open system” and “Shared Key”. When you
select “Share Key”, you need to setup “WEP” key in “Security” page (See the next section).
The default setting is “Auto”. The wireless client can associate with the device by using one
of the two types.
Fragment Threshold
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
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.
Beacon Interval
The beacon interval is the amount of time between access point beacons in mini-seconds.
The default beacon interval is 100.
ACK Timeout
The default ACK timeout is 0. You may need to change this value due to the environment or
distance.
Client Expired Time
24
The client expired time determines time interval the client need to re-associate with the
device while client is idle. The default client expired time is 300 sec.
MTU Size
Maximum Transmission Unit, the default MTU size is 1500. The MTU setting controls the
maximum Ethernet packet size your PC will send. Why a limit? Because although larger
packets can be constructed and sent, your ISP and Internet backbone routers and
equipment will fragment any larger than their limit, then these parts are re-assembled by the
target equipment before reading. This fragmentation and re-assembly is not optimal. You
may need to change the MTU for optimal performance of your wireless LAN traffic.
Data Rate
The standard IEEE 802.11b/11g supports 1, 2, 5.5, 11 / 6, 9, 12, 18, 24, 36, 48 and 54 Mbps
data rates. You can choose the rate that the device uses for data transmission. The default
value is “auto”. The device will use the highest possible selected transmission rate.
Preamble Type
The preamble is part of the 802.11 frame and is PHY dependant. All 802.11b/g systems
support the long preamble. The short preamble (optional) maybe used to improve
throughput when all stations on the network support the short preamble.
Broadcast SSID
Broadcasting the SSID will let your wireless clients find the device automatically. If you are
building a public Wireless Network, disable this function can provide better security. Every
wireless stations located within the coverage of the device must connect this device by
manually configure the SSID in your client settings.
IAPP (Inter-Access Point Protocol)
This function will let Wireless Stations roam among a network environment with multiple
devices. Wireless Stations are able to switch from one device to another as they move
between the coverage areas. Users can have more wireless working range. An example is
as the following figure.
You should comply with the following instructions to roam among the wireless coverage
areas.
Note： For implementing the roaming function, the setting MUST comply the following two
items.
All the devices must be in the same subnet network and the SSID must be the same.
If you use the 802.1x authentication, you need to have the user profile in these devices
for the roaming station.

802.11g Protection
25
This ensures that 802.11g stations are backwards compatible with legacy 802.11b
stations. With 802.11g protection enabled, a CTS will be used to lock out 802.11b stations
while the 802.11g station is transmitting. While this does allow backwards compatibility with
legacy 802.11b stations, it should be disabled in a pure 802.11g environment, as it will have
a significant impact on 802.11g performance (as high as 50% decrease in throughput).
Block WLAN Relay (Isolate Client)
The device supports isolation function. If you are building a public Wireless Network, enable
this function can provide better security. The device will block packets between wireless
clients (relay). All the wireless clients connected to the device can’t see each other.
Aggregation Mode
Not applicable for WLAN 1.
Tx Burst Mode
Not applicable for WLAN 1.
Configuring Wireless Security
This device provides complete wireless security function include WEP, 802.1x, WPA-TKIP,
WPA2-AES and WPA2-Mixed in different mode (see the Security Support Table).
The default security setting of the encryption function is disabled. Choose your preferred
security setting depending on what security function you need.
WEP Encryption Setting
Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized
access to your wireless network. The WEP setting must be as same as each client in your
wireless network. For more secure data transmission, you can change encryption type to
“WEP” and click the “Set WEP Key” button to open the “Wireless WEP Key setup”
page.
26
When you decide to use the WEP encryption to secure your WLAN, please refer to the
following setting of the WEP encryption:
64-bit WEP Encryption：64-bit WEP keys are as same as the encryption method of
40-bit WEP. You can input 10 hexadecimal digits (0~9, a~f or A~F) or 5 ACSII chars.
128-bit WEP Encryption：128-bit WEP keys are as same as the encryption method of
104-bit WEP. You can input 26 hexadecimal digits (0~9, a~f or A~F) or 10 ACSII chars.
The Default Tx Key field decides which of the four keys you want to use in your WLAN
environment.
WEP Encryption with 802.1x Setting
The device supports external RADIUS Server that can secure networks against
unauthorized access. If you use the WEP encryption, you can also use the RADIUS server
to check the admission of the users. By this way every user must use a valid account before
accessing the Wireless LAN and requires a RADIUS or other authentication server on the
network. An example is shown as following.
27
Ethernet
AP
Wireless Station
RADIUS Server
You should choose WEP 64 or 128 bit encryption to fit with your network environment first.
Then add user accounts and the target device to the RADIUS server. In the device , you
need to specify the IP address、Password (Shared Secret) and Port number of the target
RADIUS server.
WPA Encryption Setting
WPA feature provides a high level of assurance for end-users and administrators that their
data will remain private and access to their network restricted to authorized users. You can
choose the WPA encryption and select the Authentication Mode.
WPA Authentication Mode
This device supports two WPA modes. For personal user, you can use the Pre-shared Key
to enhance your security setting. This mode requires only an access point and client station
that supports WPA-PSK. For Enterprise, authentication is achieved via WPA RADIUS Server.
You need a RADIUS or other authentication server on the network.
Enterprise (RADIUS):
When WPA Authentication mode is Enterprise (RADIUS), you have to add user accounts
and the target device to the RADIUS Server. In the device , you need to specify the IP
address、Password (Shared Secret) and Port number of the target RADIUS server.
Pre-Share Key:
This mode requires only an access point and client station that supports WPA-PSK. The
WPA-PSK settings include Key Format, Length and Value. They must be as same as
28
each wireless client in your wireless network. When Key format is Passphrase, the key
value should have 8~63 ACSII chars. When Key format is Hex, the key value should have
64 hexadecimal digits (0~9, a~f or A~F).
Connecting Profile
To enable this function, this device must be in the client mode. User clicks to enable
this function and input the SSID of preferred AP and then click “Apply Changes”. The
BSSID field is an option in case of two preferred APs having the same SSID. In this
case, this device will check both SSID and BSSID and connect to the matching AP. We
can leave it empty in the normal case.
After enabling the connecting profile, the system will check the preferred SSID in a
fixed period. If preferred APs are found, the radio will try to connect with them one by
one from top to down of the list and regardless of the signal quality and strength. The
users can put their most favorite AP on the top so it will be connected first. Please note
that check the preferred APs will impact the throughput a lot! Unless the signal strength
is good enough, otherwise don't set the interval too short. The default value is 10
minutes. And currently, all the profiles share the same security setting.
To delete one SSID in the list, users click the square to select it and click “Delete
Selected” and then click “OK” in the pop-up window to confirm it. The user can delete
29
the whole list once for all! Just click “Delete All” and then click “OK” in the pop-up
window to confirm it.
To simply disable this function, the user just clicks to disable “Enable connecting
profile”. The preferred AP list will be preserved for the next use.
MAC Clone for Single Ethernet Client
Enable/Disable Mac Clone (Single Ethernet Client) in Wireless-Basic Settings page
determines whether the Ethernet Client use it’s own MAC address or AP-Client’s MAC
address to transmit data. Enable MAC Clone, the single Ethernet client can use its own
MAC address. Disable MAC Clone, the single Ethernet client must to use AP-Client’s
MAC address.
While you use this device act as AP-Client and only one host connect to this device via
Ethernet, you need to check this option in this page, otherwise the other device can’t
recognize your host behind AP-Client. If you use hub/switch connect multi-device to this
AP-Client, you should uncheck this option.

Associated Client:
Show the information of active wireless client stations that connected to the device.
Advanced Settings
These settings are only for more technically advanced users who have sufficient
knowledge about wireless LAN. These settings should not be changed unless you
know what effect the changes will have on your device. The default setting is optimized
for the normal operation. For specific application, setting configuration will required
highly attention to reach optimistic condition.
Note：
Any unreasonable value change to default setting will reduce the throughput of the
device.
38
Authentication Type
The device supports two Authentication Types “Open system” and “Shared Key”. When you
select “Share Key”, you need to setup “WEP” key in “Security” page (See the next section).
The default setting is “Auto”. The wireless client can associate with the device by using one
of the two types.
Fragment Threshold
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
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.
Beacon Interval
The beacon interval is the amount of time between access point beacons in mini-seconds.
The default beacon interval is 100.
ACK Timeout
The default ACK timeout is 50. You may need to change this value due to the environment
or distance.
Client Expired Time
39
Not applicable for WLAN 2.
MTU Size
Maximum Transmission Unit, the default MTU size is 1500. The MTU setting controls the
maximum Ethernet packet size your PC will send. Why a limit? Because although larger
packets can be constructed and sent, your ISP and Internet backbone routers and
equipment will fragment any larger than their limit, then these parts are re-assembled by the
target equipment before reading. This fragmentation and re-assembly is not optimal. You
may need to change the MTU for optimal performance of your wireless LAN traffic.
Data Rate
The standard IEEE 802.11a supports 6, 9, 12, 18, 24, 36, 48 and 54 Mbps data rates. You
can choose the rate that the device uses for data transmission. The default value is “auto”.
The device will use the highest possible selected transmission rate.
Preamble Type
The preamble is part of the 802.11 frame and is PHY dependant. All 802.11a systems
support the long preamble. The short preamble (optional) maybe used to improve
throughput when all stations on the network support the short preamble.
Broadcast SSID
Broadcasting the SSID will let your wireless clients find the device automatically. If you are
building a public Wireless Network, disable this function can provide better security. Every
wireless stations located within the coverage of the device must connect this device by
manually configure the SSID in your client settings.
IAPP (Inter-Access Point Protocol)
Not applicable for WLAN 2.
802.11g Protection
Not applicable for WLAN 2.
Block WLAN Relay (Isolate Client)
The device supports isolation function. If you are building a public Wireless Network, enable
this function can provide better security. The device will block packets between wireless
clients (relay). All the wireless clients connected to the device can’t see each other.
Aggregation Mode
This is a proprietary Ralink (802.11a chipset in the DLB70xx) aggregation setting that allows
for jumbo frames consisting of multiple smaller frames that increases throughput between
Ralink stations.
Tx Burst Mode
This is a proprietary Ralink (802.11a chipset in the device) burst setting and allows very
small networks (1~3 clients) to transmit at higher speeds. In larger networks, this will result
in degraded performance.
40
Configuring Wireless Security
This device provides complete wireless security function include WEP, 802.1x, WPA-TKIP,
WPA2-AES and WPA2-Mixed in different mode (see the Security Support Table).
The default security setting of the encryption function is disabled. Choose your preferred
security setting depending on what security function you need.
WEP Encryption Setting
Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized
access to your wireless network. The WEP setting must be as same as each client in your
wireless network. For more secure data transmission, you can change encryption type to
“WEP” and click the “Set WEP Key” button to open the “Wireless WEP Key setup”
page.
When you decide to use the WEP encryption to secure your WLAN, please refer to the
following setting of the WEP encryption:
64-bit WEP Encryption：64-bit WEP keys are as same as the encryption method of
40-bit WEP. You can input 10 hexadecimal digits (0~9, a~f or A~F) or 5 ACSII chars.
41
128-bit WEP Encryption：128-bit WEP keys are as same as the encryption method of
104-bit WEP. You can input 26 hexadecimal digits (0~9, a~f or A~F) or 10 ACSII chars.
The Default Tx Key field decides which of the four keys you want to use in your WLAN
environment.
WEP Encryption with 802.1x Setting
The device supports external RADIUS Server that can secure networks against
unauthorized access. If you use the WEP encryption, you can also use the RADIUS server
to check the admission of the users. By this way every user must use a valid account before
