Chapter 1 Introduction
Thank you for choosing 802.11b/g Ethernet-to-Wireless Bridge—
Dolphin-M. Dolphin-M is an IEEE 802.11g standard wireless
bridge enabling a laptop, pc or embedded device with Ethernet port
without build-in wireless capability to connect to a wireless LAN.
It delivers a 54Mbps high speed and fully compliant with 802.11b
& 802.11g standard, and could easily be changed to support
802.11a standard by inserting the 802.11a compliant mini-PCI
wireless module, it has two working mode: Infrastructure and Adhoc.
Dolphin-M provides both basic 64/128-bit WEP encryption and
Wi-Fi Protected Access(home WPA, professional WPA2). It’s
completely driver-free, so it works on any platform and under any
operating system! Since there’s no drivers to load, setup is a snap—
configure the network settings through your PC’s web browser,
then plug it into your device and go, it also has the ability to be
configured through your device’s Ethernet port.
Dolphin-M provides highly stable, secure, flexible and reliable
wireless connection. This guide shows you how to setup and
connect Dolphin-M wireless bridge to your wireless LAN.

Using the WEB management
The WEB management offers a friendly user’s interface. You can
look into and configure the device through the browser.
1. First activate the IE, and type the default IP:
Please set the IP Net segment of the PC adapter to the same as
the bridge.
2. Enter the login windows, input the default user name and
password, press “OK” button, then you can enter the main
page and set the device.

Dolphin-M User’s Manual
●Wireless Mode
There are two wireless modes for the bridge to operate. If you
need to access company network or Internet via an Access Point,
select “Infrastructure”. To set up a group of wireless stations for
files and printer sharing, select “Ad-Hoc” (without Access Point).
For Ad-Hoc operation, the same ESSID is required to set for the
wireless stations.
●Wireless Network Name(SSID)
The SSID is a unique ID used by Access Points and Stations to
identify a wireless LAN. Wireless clients associating to any Access
Point must have the same SSID. The default SSID is “ZQNET”.
The SSID can up to 32 characters.
●Transmission Rate
Transmission rates options include Best(automatic), 1, 2, 5.5, 11,
6, 9, 12, 18, 24, 36, 48 and 54Mbps. The default setting is
●802.11 Mode
There are four different 802.11 wireless modes to operate,
“802.11b only”, “802.11g only”, “Mixed 802.11g and 802.11b”,
and “802.11a only”. In 802.11b/g mixed mode, the bridge is
compatible with a mix of both 802.11g and 802.11b AP. The
802.11a mode is only valid when compliant 802.11a mini-PCI
wireless module is deployed.
●Super mode
There are four super mode options to select, “Disabled”, “Super
A/G without Turbo”, “Super A/G with Static Turbo” and “Super
A/G with Dynamic Turbo”, the last three modes need the support
of corresponding wireless module.

Only need to configure the channel when the bridge works in
Ad-hoc mode, when the bridge works in infrastructure mode, the
channel is auto running after the AP’s.

Chapter 3 Security Configuration
Security Setup
You can press the item “Security” on the left column to configure
the wireless security parameters to enhance the security of the
wireless network.
WPA setup
Figure 5 WPA setup
●WPA Enable
Check the box to enable WPA security if you use the WPA for
the wireless data encryption.
●WPA Mode
WPA — WPA home
WPA2 — WPA professional
●Cipher Type
There are three cipher types to be selected:
TKIP — Temporal Key Integrity Protocol
AES — Advanced Encryption Standard
Dolphin-M User’s Manual
●PSK(Pre-Shared Key)
The length of PSK should be 8~64 characters.
WEP setup
Figure 6 WEP setup
●WEP Enable
Check the box to enable the WEP security if you use the WEP for
the wireless data encryption.
●Default WEP key to use
You can select one of the four WEP keys to be used as the default
Dolphin-M User’s Manual
There are two types of authentication: Open, Shared Key.
Open — It requires no authentication since it allows any device to
join a network without performing any security check.
Shared Key — It provides higher security for wireless access. Note
that when Shared Key is selected, a WEP key is required and must
be the same between the Access Point and client.
●WEP key lengths
64 bit(10 hex digits) — Requires the wireless bridge to use data
encryption with 40-bit algorithm when communicating with the
Access Point.
128 bit(26 hex digits) — Requires the wireless bridge to use data
encryption with 104-bit algorithm when communicating with the
Access Point.
●WEP key
You may enter 10(64 bit WEP) or 26(128 bit WEP) hexadecimal
digits in the range of “A-F”, “a-f” and “0-9” into the box of default
WEP key, and the same length digits to others or keep other key

MAC address clone
Controls the MAC address of the bridge as seen by other devices,
there are two options to the cloning mode: WLAN card, Ethernet
client. If set to “WLAN card” (default), the MAC address of
WLAN card will be used, if set to “Ethernet client” , the MAC
address from the first Ethernet client that transmits data through
the bridge will be used.

●Fragmentation threshold
Fragmentation mechanism is used for improving the efficiency
when there is high traffic within the wireless network. If you
transmit large files in a wireless network, you can enable the
Fragmentation Threshold and specify the packet size.
●RTS threshold
RTS threshold is a mechanism implemented to prevent the “hidden
node” problem. “Hidden node” is a situation in which two stations
are within range of same Public Access Point, bur are not range of
each other. Therefore, they are hidden nodes for each other. When
a hidden station starts data transmission with the Public Access
Point, it might not notice that another station is already using the
wireless medium. When these two stations send data at the same
time, they might collide when arriving simultaneously at the Public
Access Point. The collision will most certainly result in a loss of
messages for both stations. Thus, the RTS threshold mechanism
will provide the solution to prevent data collisions. When the RTS
threshold is activated, the station and its Public Access Point will
use a Request to Send/Clear to Send protocol (RTS/CTS). The
station will send an RTS to the Public Access Point, informing that
it is going to transmit the data. Upon receipt, the Public Access
Point will respond with a CTS message to all stations within its
range to notify all other stations to defer transmission. It will also
Dolphin-M User’s Manual
confirm to the requesting station that the Public Access Point has
reserved the channel for transmission.
●Beacon period
The amount of time between beacons in kilo microseconds.
Enable the support for receiving the regional information from
Access Point.
●Transmit Power
There are three level of transmit power: High (default), Medium
and Low. Under default status – high transmit power, gain the
more wide range; Set to Medium or Low transmit power may
reduce the radiation to the circumstance.
●Antenna selection
There are three antenna working mode: Use antenna diversity
(default), Use antenna #1 and Use antenna #2.
