ADSL Router Wireless Operation & Setup
1Introduction
A Wireless Local Area Network (WLAN) serves the same purposes as a conventional
wired Ethernet network (LAN). On a Wireless LAN computers are linked together
y radio waves.
The RTA300W is your Internet access point and it is also your WLAN access point.
It provides sharing of network resources including Internet access among wireless
clients and wired clients. The RTA300W complies to the IEEE 802.11 standard,
ensuring connectivity among all wireless clients that meet the same standard
irrespective of vendors.
1.1 T e RTA300W can be set up for two types of network configurations
1. An infrastructure network
The RTA300W is attached to an existing Ethernet network via one of its
Ethernet ports. In an infrastructure network, the RTA300W connects wireless
clients to a wired network. This ena les the wireless clients to share all availa le
resources including Internet access and peripherals on the wired network.
2. A stand-alone wireless network
This is a computer network free of wired clients connected via Ethernet ca les.
The RTA300W acts as a relay station for all wireless clients. It ena les
information transfer among wireless stations within its coverage area. Its
relay capa ility can e utilised to effectively dou le the communication
distance etween two wireless stations.
1.2 Wireless Privacy
Privacy is an important issue with wireless communication. The RTA300W provides
the following functions for access control and security:
1. Service Set ID (SSID). This is a user specified name that uniquely identifies
a wireless domain. All wireless clients that need to associate with your
RTA300W must e set with identical SSID.
2. Association control (or MAC address filtering). The user can determine which
wireless clients are authorised to associate with the RTA300W y registering
the client’s unique MAC address on the RTA300W.
3. Wired Equivalent Privacy (WEP) is an authentication algorithm that protects
users from eavesdropping. When ena led, all wireless stations and your
RTA300W always transmit data encrypted using a key of your choice. The
receiving station will use the same key for decryption. Receiving station will
use the same key for decryption.

Setup wireless networking
The wireless function of your RTA300W is activated y default. The WLAN light
comes on indicating the wireless interface is ready. By default, Association
Control and WEP encryption are disa led.

STEP 1
Initially connect the RTA300W to a
computer (or network) via the Ethernet
port to configure for wireless operation.
Start your we rowser. Enter the
RTA300W’s IP address (default
ttp://192.168.1.1). You will e
prompted to enter the RTA300W’s
administrative user name and
password. By default, the user name
and password are oth admin.
STEP 2
Go to Configuration - WLAN - Basic
Setup. It is strongly recommended that
you use a SSID of your choice. Next
pick a desired channel. There are 14
channels availa le. Wireless clients will
scan and settle on the same channel
as the RTA300W.
STEP 3
Decide if you want to use Association
Control and/or WEP encryption. Follow
the next section for setting up these
functions. We strongly recommend at
least ena ling Association Control to
restrict unauthorized wireless clients
from accessing your network.
STEP 4
Setup wireless client stations according
to the vendor’s instructions. Select
infrastructure for associating with a
wireless access point. Do not use adhoc
(or peer-to-peer) mode. Check that
every wireless client has an identical
SSID to the RTA300W. You should see
the wireless client using the same
channel as the RTA300W. If not, pick
the correct channel on the wireless
client manually according to the
vendor’s instructions.
STEP 5
To verify that a wireless station is
associated with the RTA300W, go to the
router control panel and then Status -
Wireless Client. The ta le will display
the MAC address of every wireless client
that associates with the RTA300W.
E.g. If you are using a Dynalink wireless client
Run the Monitor Utility. Select Infrastructure
and enter the correct SSID. Click Su mit to take
effect. Channel is selected automatically
according to the setting of the RTA300W.

Setup access control & encryption (optional)
ASSOCIATION CONTROL
By default every client having the same SSID is capa le of connecting to the
RTA300W. Association control is used for locking access from unauthorised clients.
Go to the router control panel. Then Configuration - WLAN - Association Control.
Enable Association Control and enter the MAC address of every authorised client
as illustrated. Each pair of digits must e separated y a “:”. Click Apply.

E.g. If you are using a Dynalink wireless client
The unique MAC address is printed on a la el affixed to the product. Alternatively read off the
MAC address y running the Monitor Utility as shown in Step 5 of Section 2.
WEP ENCRYPTION
Go to Configuration - WLAN - Basic Setup.
1. In the Wired Equivalent Privacy Mec anism field select ON.
2. Select either 64-bit or 128-bit encryption.
3. Enter the WEP keys of your choice in the Key1-4 fields. WEP keys must
comprise of hexadecimal characters (0-9 and a-f) and must contain 10
characters for 64- it WEP Keys or 26 characters for 128- it WEP keys. Each
pair of digits must e separated y a “-“. Alternatively, enter a string of your

choice into Use passcode to generate WEP keys. This method saves the user from
filling in the key ta le.
4. In the Default Transmission Key field, select one of the four keys to encrypt data.
5. On every wireless client, follow the
vendor’s instructions to setup WEP
encryption on the client station. The
encryption ta le must match the settings
of the RTA300W. Failing that the client will
e una le to communicate to the network.
When WEP is set all stations transmit data
encrypted using the Default Key. The key
num er 1, 2, 3 or 4 is also transmitted. The
receiving station will use the key num er to
determine which key to use for decryption.
If the key value does not match with that of
the transmitting station, decryption will fail.
E.g. If you are using a Dynalink wireless client
Run the Monitor Utility. Go to Encryption. Select the correct key length 64 /128 Bit to match the RTA300W
setting. Click on HEX and copy the values of all keys displayed from the RTA300W into the corresponding
fields. Check that the WEP Key to use num er matches the Default transmission key on the RTA300W.

Cannot establish a wireless link to the RTA300W
Check that the WLAN light on the front panel of the RTA300W is on.
Make sure the RTA300W and wireless clients are configured with the same SSID.
If Association Control is ena led, check that the client’s MAC address has
een entered into the list of authorised clients on the RTA300W.
If WEP is turned on, make sure all wireless stations are using the same
encryption algorithm and the same WEP key ta le as the RTA300W.
How to find the AC addresses of my wireless clients
If the wireless client has not een installed, follow the vendor’s instructions
to find the device’s MAC address. Usually it is printed on a la el affixed to
the device.
If the wireless client is already installed on the computer, an alternative is to
go to the DOS (Command) prompt and type ipconfig /all. The MAC address
is shown under p ysical address as a group of 6 dou le digits.
Radio interference
Other wireless devices and appliances on site may share the same 2.4 GHz
and. If undesira le effects are o served, trying switching the RTA300W to
a different channel. Alternatively, switch the other devices to use a different
channel.
