Installation
Preparation for Installation
Always double check for any missing parts from the kit you received before deployment.
Next step is to set up the computer Ethernet interface for configuring the MiniLink. Since the default IPAddress of the
unit is on the 192.168.0.x IP range in both Client Bridge and AP mode you’ll need to set the computer Ethernet
interface within the same IP range, where the x will have to be a free IP address number from 1-254.
Check the following section - “Hardware Installation” and the next chapter - “Configuring Windows for IP Networking” to
obtain complete details.
Hardware Installation
Follow the procedure below to install your MiniLink device:
1. Select a suitable place on the network to install the MiniLink. For best wireless reception and performance the
external antenna should be positioned within Line of Sight from the AP with proper alignment.
2. Connect the MiniLink to the ODU side of the PoE Injector, via a straight Ethernet cable (Cat-5), then connect the
NET side of the PoE Injector to either a computer or an Ethernet Switch.
3. Connect the 24VDC power adapter to the power jack on the PoE injector to power on the MiniLink.
4. Now the hardware installation is complete, and you may proceed to the next chapter –“Configuring Windows for
IP Networking” for instruction on setting up network configurations.

Configuring Windows for IP Networking
How to assign a static IP Address in Windows XP/2000?
1. Go to “Start” > Click on “Control Panel” > Double-click on “Network
Connections” > Right-click on “Local Area Connections” > Click
“Properties”
2. Highlight “Internet Protocol (TCP/IP)” and then click “Properties”.

3. Select Use the following IP address in the Internet Protocol
(TCP/IP) Properties window. Set your IP address and subnet
mask. (The IP Address must be within the same range as your station
adapter. The IP Address of your station adapter is 192.168.0.2. You can
assign 192.168.0.100 for your computer. No two computers can have
the same IP Address. Assign a subnet mask of (255.255.255.0.) and
then Click OK button.
Congratulations! You have now successfully assigned a Static IP Address in
Windows XP/2000.
Note: Again the IP address must be in the format of 192.168.0.x. Where the value of X should be
ranged from 1 to 254, excluding 2.
4. Click OK.

Web Configuration Interface
Activate your browser, then type this Station Adapter’s address (e.g.
http://192.168.0.2), in the Location (f or IE) or Address field and press
Enter. Key in the system password (the default setting is default ) and
click on the Login button. You will see the main page.
The main window provides 5 items for you to monitor and configure the
Wireless LAN Access Point: Information, Configuration, TCP/IP,
Statistics and Firmware Upgrade.
Information
This item shows the current information on the 802.11g Wireless LAN
Station Adapter such as MAC Address, Firmware Version as well as Boot
Version.

Configuration
General:
Station Adapter Name: In this field, you may enter any name. This will
enable you to manage your Station Adapter more easily if you have
multiple station adapters on the network. Besides, Station Adapter
Name can be used to prevent you from forgetting an IP Address and fail
to access the website. Try to type the nickname you like to identify the
website, then press the button of “Apply” to reboot. Whenever you want
to get back to the website again, just type the name you login.
ESSID: The ESSID 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 ESSID. The default ESSID is ANY. The ESSID can
have up to 32 characters.
Network Type: There are 2 network types for the wireless station
adapter to operate. If you need to access company network or Internet
via 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.

Channel: Select a clear and available channel as an operational channel
for your wireless station adapter when it performs as Ad-Hoc mode.
Mode: There are three different wireless modes to operate, “B Only
Mode”, “G Only Mode”, and “B/G Mixed Mode”. In B/G Mixed Mode, the
wireless station adapter is compatible with a mix of both 802.11g and
802.11b clients. You will see that the factory-set default “B/G Mixed Mod”
will prove the most efficient. B Only Mode is compatible with 802.11b
clients only. This mode can be used only if you do not allow any 802.11g
clients to join a network. G Only Mode is compatible with 802.11g clients
only. This mode can be used only if you do not allow any 802.11b clients
to access to the network. To switch the mode, select the desired mode
form the pull-down menu next to “Mode”.
Rate: The wireless station adapter provides various data rate options for
you to choose. Data rates options include Auto, 1, 2, 5.5, 11, 6, 9, 12,
18, 24, 36, 48 and 54. The default setting is Auto.
Country/Region: Allows you to select country domain in case there is
any chances that you would use wireless network in other countries.
There are a total of 11 countries for you to select. They are Africa, Asia,
Australia, Canada, Europe, France, Israel, Japan, Mexico, South America,
and USA. Note that if your AP and station adapter are in different
standards, please use the “Country/Region” item to switch the
standards of the station adapter (For example, if your Access Point is
America standard but your station adapter is Japanese standard, you can
pull down the “Country/Region” option to switch your station adapter
from Japanese standard to American standard.).
Password: You may change the default password by entering the new
password.
Click “Apply” if you have made any changes.

SECURITY:
WEP:
The wireless station adapter allows you to create up to 4 data encryption
keys to secure your data from being eavesdropping by unauthorized
wireless user. To enable the encryption, all devices on the network, such as
the Access Point, must share the same WEP selection – either Enable or
Disable, and they must share the same WEP key.
Disable: Allows the wireless station adapter to communicate with the
Access Point without any data encryption.
WEP40: Requires the wireless station adapter to use data encryption
with 40-bit algorithm when communicating with the Access Point.
WEP128: Allows the wireless station adapter to communicate with the
Access Point with data 128-bit encryption algorithm.
WPA: Allows the wireless station adapter to communicate with the
Access Point with a more secure data protection than the WEP. Here you
can select the WPA with PSK mode to improve the data security and
privacy during wireless transmission. The present WPA supplied with this
station adapter is used in a pre-shared key mode, which does not require
an authentication (Radius) server.

For 40bit encryption you may choose:
ASCII: Enter 5 characters (case sensitive) ranging from “a-z”, “A-Z”
and “0-9” (e.g. MyKey).
Hex: Alternatively, you may enter 10 hexadecimal digits in the range
of “A-F”, “a-f” and “0-9” (e.g. 11AA22BB33).
For 128bit encryption you may choose:
ASCII: Enter 13 characters (case sensitive) ranging from “a-z”, “A-Z”
and “0-9” (e.g. MyKey12345678).
Hex: Alternatively, you may enter 26 hexadecimal digits in the range
of “A-F”, “a-f” and “0-9” (e.g. 00112233445566778899AABBCC).
After entering the WEP keys in the key field, select one key as active key.
Alternatively, you may create encryption keys automatically by using
Passphrase. From the Passphrase field, type a character string and click
Generate. As you type, the wireless station adapter will use an algorithm to
generate 4 keys automatically. Select one key from the 4 WEP keys.
Moreover, the wireless station adapter provides two types of authentication
services: Open System and Shared Key. The default authentication type is
Open System. If you require higher security for wireless access, you may
select Shared Key. Note that when Shared Key is selected, a WEP key is
required and must be the same with the key that Shared-Key-enabled AP
uses.
For WPA-PSK mode you may choose:
In the WPA-PSK field, you may enter 8-63 characters ranging from “a-z”,
“A-Z” and “0-9”.

WDS Mode
The Wireless Distribution System (Repeater) functionality enables this AP to support wireless
traffic to other WDS relayAccess Points. In other words it is like bridging between the 2 access
points in order to extend the reach of the wireless network beyond that of a single AP. By enabling
the WDS feature the coverage area of the wireless network is thus extended for authenticated
client devices that can roam from this Access Point to another. WDS can extend the reach of your
network into areas where cabling might be difficult.
Enter the MAC Address of other Access Points in the area that you want to add to the WDS. The
MAC Address of this Access Point should be also be added to other access points in the same
WDS network to enable intra-AP communication.

Access Control
This feature contains an address list for you to control the accessibility from wireless devices.
There are three types of modes: 1) “Open” mode will allow you to associate to other units/devices
to the public. 2) “Allow” mode will allow you to associate network access from devices in the
address list. 3) “Deny” mode will not allow you to associate network access from devices in the
address list.
SNMP
Option to enable or disable SNMP support.
The SNMP Read-only Community string is like a user id or password that allows access to a
router's or other device's statistics. InterMapper sends the community string along with all SNMP
requests. If the community string is correct, the device responds with the requested information. If
the community string is incorrect, the device simply discards the request and does not respond.
Factory default setting for the read-only community string is set to "public". It is standard practice to
change all the community strings so that outsiders cannot access/read information about the
internal network. (In addition, the administrator may also employ firewalls to block any SNMP traffic
to ports 161 and 162 on the internal network.)

Parameter Log
This feature enables a user to save their current settings to their local hard drive of
their PC. This is primarily use for importing and exporting configurations/settings.
Advanced
RTS threshold
RTS Threshold is the frame size above which an RTS/CTS handshake will be performed
before attempting to transmit. RTS/CTS asks for permission to transmit to reduce
collisions but adds considerable overhead. Disabling RTS/CTS can reduce overhead
and latency in WLANs where all stations are close together but can increase collisions
and degrade performance in WLANs where stations are far apart and unable to sense
each other to avoid collisions (aka Hidden Nodes). If you are experiencing excessive
collisions you can try turning RTS/CTS on or (if already on) reduce RTS/CTS Threshold
on the affected stations.
Fragmentation threshold
Fragmentation Threshold is the maximum length of the frame beyond which payload
must be broken up (fragmented) into two or more frames. Collisions occur more often

for long frames because sending them occupies the channel for a longer period of
time, increasing the chance that another station will transmit and cause collision.
Reducing Fragmentation Threshold results in shorter frames that "busy" the channel
for shorter periods, reducing packet error rate and resulting retransmissions.
However, shorter frames also increase overhead, degrading maximum possible
throughput, so adjusting this parameter means striking a good balance between error
rate and throughput.
Beacon Period
In wireless networking, a beacon is a packet sent by a connected device to inform
other devices of its presence and readiness. When a wirelessly networked device
sends a beacon, it includes with it a beacon interval which specifies the period of time
before it will send the beacon again. The interval tells receiving devices on the
network how long they can wait in low-power mode before waking up to handle the
beacon. Network managers can adjust the beacon interval, usually measured in
milliseconds (ms) or its equivalent, kilo microseconds (Kμsec).
DTIM interval
A Delivery Traffic Indication Message (DTIM) is a signal sent as part of a beacon by an
access point to a client device in sleep mode, alerting the device to a packet awaiting
delivery. A DTIM interval, also known as a Data Beacon Rate, is the frequency at
which an access point's beacon will include a DTIM. This frequency is usually
measured in milliseconds (ms) or its equivalent, kilo microseconds (Kμsec).

TCP/IP
You may assign a proper IP address to your wireless station adapter
manually. If you would like the wireless station to obtain the IP address from
the DHCP server on your network automatically, enable the DHCP client
function.
