5 BASIC IP NETWORKING
Internet Protocol (IP)
IP stands for Internet Protocol. In an IP network, every device has a unique IP Address (For
example: 192.168.1.35) to identify itself. There are two ways of assigning an IP address to a PC
or Router: Static and Automatic (DHCP). Static IP addresses are keyed-in manually, while
Dynamic IPs are distributed by a DHCP Server.
Ports
Every packet of traffic is identified by its Source and Destination Addresses, which would ensure
that the packet arrives at the correct destination. A Port Number is also embedded in each
packet; to identify which software application that generated and uses that packet. Therefore, if
the Router blocks a certain port number, it denies the particular software from using the
connection.
Static IP Address
Static IP addressing ensures that the device will always have the same IP address. Static
addressing is commonly used for your servers.
Dynamic IP Address
A dynamic IP address is one that is automatically assigned to a PC. These IP addresses are
“dynamic” because they are only temporarily leased to the PC when it connects to the network.
This is the most convenient and common way of managing IP addresses in a network. The
Server that manages this pool of IP addresses is called the DHCP Server. The product has a
DHCP Server built-in to simplify the network management.
DHCP (Dynamic Host Configuration Protocol)
The PC obtaining an IP address from the Server is called the DHCP Client. If there is already a
DHCP Server running on your network, you must disable one of the two DHCP servers. Running
more than one DHCP server together will cause network problems!
What is a Router?
A router is a network device that connects two networks together, to let them communicate. All
the PCs in your home or office would be considered to be in one network: the Local Area Network
(LAN). The Internet (including the ADSL modem) is considered to be another network: the Wide
Area Network (WAN). The Router serves 2 purposes:
Connect all the PCs in the LAN together, allowing them to communicate with one
another. (File sharing, Printer sharing etc.)
Connect all the PCs in the LAN to the Internet, allowing them to simultaneously surf the
web and access e-mails.
The Router is connected to 2 networks at the same time. Therefore, it has two IP addresses: one
for the LAN, and one for the WAN. The Router’s LAN IP address can be configured, but it is best
to use the default settings. The WAN port is a DHCP client by default.
Page 8 of 45
Wireless LAN Basics
A Wireless LAN (WLAN) is a computer network that transmits and receives data with radio
signals instead of using cables. WLANs have become common in homes, offices, airports and
public Hotspots. WLAN can support the same applications and software that run on a wired
network (LAN). Besides supporting the same software and functions, WLAN brings greater
convenience and eliminates the need to lay Ethernet cables in a home or office.
The Router is based on the finalised 802.11g standard. The IEEE 802.11g standard is an
improvement on the 802.11b (WiFi) standard. It increases the data rate up to 54 Mbps within the
2.4GHz band. As the 802.11b standard is also using the 2.4GHz frequency band, the product is
fully backward compatible with the older 802.11b devices. WiFi cards can be used to connect to
the Router at 11Mbps.
The Router can even support 108Mbps WLAN if the user is using a recommended Turbo-capable
Cardbus.
The Router is also known as the Wireless Access Point (AP). The PC using the Cardbus is
known as the Client. WLAN networking involves a few additional parameters to be configured:
SSID
The SSID is the “network name” for the WLAN network. The SSID is any name, and can be any
set of characters or numbers, and must be configured on both the AP and Client. The Client sniffs
the radio frequencies for an AP with the same SSID with itself. The client locks onto the AP and
they are “associated”.
To enable plug-and-play convenience, most client cards can sniff the frequencies to extract the
available SSIDs to let the user choose from. Alternatively, setting the client’s SSID to “ANY” can
allow it to connect to most APs regardless of the AP’s SSID setting.
Encryption
WLAN traffic can be captured by anybody to be read! The solution is to use encryption to make
the traffic appear as random characters to the eavesdropper. Both the AP and client must use the
same encryption standard and key to enable them to decode the “rubbish”. If the encryption
settings are mismatched, the client and AP cannot associate. WEP (Wired Equivalent Privacy) is
the most common WLAN encryption standard.
MAC Address Control
Every client card has a unique MAC Address. This MAC Address can be input into the AP
(Router), such that the AP only allows this pool of MAC Addresses to use the WLAN.
Channel
There are a total of 11 channels in the 2.4GHz band. Depending on regulation, not all the
frequencies may be available in every country. Frequency is configured on the AP only. The client
searches for the AP and locks onto that AP’s channel.
Signal Strength
Radio signals drop in power over a distance. Even if all the settings are correct, a low signal
strength makes association impossible. The usable distance between the AP and client can
range from a few meters indoor to 200m outdoors maximum. When setting up the AP, make sure
that you:
Keep the distance from the AP to the clients as short as possible.
Make sure that the WLAN signals do not have to pass through too many concrete walls
and metal structures to reach the client.
Page 9 of 45
Make sure that APs are located far away from one another to avoid interference.
Interference
Interference happens when 2 APs with the same channels are placed near to one another. The
speed of the network drops and the signal strength fluctuates wildly.
Roaming
Association happens when the SSID, Encryption and MAC Address Control settings are correct
between the AP and client. If 2 APs with these same settings are located in the same area, the
client would choose to associate to the one which gives it a better signal strength. The client
would roam over to the 2nd AP when he moves nearer to it. The client switches AP and
frequency as he does so.

Page 23 of 45
Wireless > Basic Setting
This page lets you configure the Wireless settings of the Router. There are 2 sections: Radio and
Security.
Enable Wireless: Tick to enable wireless function. With this function, laptop with cardbus or in-
built wireless function can access the Router wirelessly.
SSID: Service Set Identifier. It is a sequence of characters that uniquely names a Wireless LAN.
This name allows PCs to connect to the correct Wireless Access Point when multiple Access
Points (or Wireless Routers) operate in the same location.
Channel: The radio channel number. You can select channel 1 to 11 or use SmartSelect, where
the Router will select the cleanest channel to use upon booting up. The number of channels
varies according to countries.
SSID Suppressed: When SSID is suppressed, the router will not broadcast the SSID.
Unwelcome PCs will not be able to scan for the SSID of this Router, and they can only associate
if they know exactly what is the SSID.
Wireless Mode: You can choose to operate the Router in 802.11g or 802.11b mode. The data
rate for 802.11g is 54Mbps while the data rate for 802.11b is 11Mbps. 802.11g is backward
compatible with 802.11b.
For model APRT-2518gs, you will be able to select Dynamic Turbo or Static Turbo Mode. Turbo
mode operates in 108Mbps.
Security Mode: This section allows you to configure wireless encryption to prevent unwelcome
parties from reading your traffic. You must Enable the Security Mode before choosing the type of
wireless security.
Page 24 of 45
Open-System/Shared Key
Open-System: When chosen, the Key is not used for authentication. It is only used for
encryption. Open-System uses Static Keys for encryption. Static (Shared) Keys are never
changed, and a hacker can crack the key after a period of time.
Shared-Key: When chosen, the encryption Key is also used for authentication between the
Router and Client. Note that this system is also using Static Keys.
Key Entry Method: Choose HEX if you want to enter the Keys in hexadecimal format. Otherwise,
enter in ASCII format. ASCII is also called Alphanumeric in some systems. Use the same key
format for the Router and Client!
Key 1-4: The Key is to be entered in the boxes. The SAME Key must be entered in both the
Router and Client. Take note that there is a different Key length for a different number of
encryption bits. 152 bits is the most secure, but make sure that your Client card supports it. The
last point to take note is that if you use Key 4 on the Router, you must also use Key 4 on the
Client, for example. The same logic applies for Keys 1-3.
WPA-PSK
WPA-PSK is also known as WPA-Preset-Key. This implementation is more secure than WEP as
the encryption is automatically changed periodically. To configure this feature, just key in a 8-63
ASCII character or 64 HEX character pass-phrase for both the Router and Cards.
Cipher: You can choose to use TKIP or AES for the cipher type.
Page 25 of 45
WPA
WPA (WiFi Protected Access) is a standard where the Wireless Card has to authenticate to a
RADIUS Server, through the Access Point. The Server can also manage the encryption keys
such that they are changed dynamically. You need to have a RADIUS Server to be able to use
this feature.
RADIUS Server: Enter the IP Address and the port of the RADIUS Server.
Shared Secret: Enter the Shared Secret of the RADIUS Server.
Confirm Source: Enter the Shared Secret again to confirm.
Wireless > Advance Setting
This page allows you to configure the advance wireless setting of the Router.
(18dBm)
Data Rate (Mbps): You can set the wireless data rate from the available list or choose Best to
allow the Router to choose the most appropriate data rate. When Best is used, the Router will
determine the optimal data rate according to the environment.
Transmit Power: This adjust the transmit power of the antenna. Sometimes, it is useful to
decrease the coverage range of each Router, so that more Routers can be located together
without interfering one another.
Preamble: Choose Short Preamble or Long Preamble. Most manufacturers implement long
preambles. Even if there is a mismatch between the Router and the card, they can still connect
well and the mismatch may not be noticeable to most users. Do not change this setting without
seeking advice.
Slot Time: Choose short or long slot time. The slot time is the amount of time a device waits
after a collision before retransmitting.
Page 26 of 45
Wireless > MAC Address Control
This page allows you to specify which wireless computer can access the Internet and which
wireless computer cannot access the Internet. The specified MAC address and the policy for the
computer are reflected in the table.
Enable Wireless MAC Control: Tick to enable Wireless MAC Control.
Default Policy: This policy determines whether computers, whose MAC addresses are not in the
table, are able to access the Internet. If you choose Deny All, all computer associated to the
Router will not be able to access the Internet other than those specified in the table.
MAC Address: Enter the MAC address of the computer. The format for the MAC address is
aa:bb:cc:dd:ee:ff.
Policy: Choose to deny or allow the computer to access the computer. Click on the Add button to
add the policy.
DHCP > DHCP Server
This page is to configure the properties of the Router’s built-in DHCP Server. Take note that the
built-in DHCP Server distributes IP Addresses to both the LAN ports and the WLAN clients.
Enable DHCP Server: Tick to enable the built-in DHCP (Dynamic Host Configuration Protocol)
Server. When enabled, the Router will provide IP addresses to the computers connected to the
router.
IP Address pool: When ‘System Define’ is selected, router will assign IP address automatically
from the pre-defined pool. If ‘User Define’ is selected, you would have to define the range of the
pool manually.
Page 27 of 45
IP Address pool (For User Defined only), Start Address: This is the start address of the DHCP
pool. The router will assign this to the first computer connected to the router.
IP Address pool (For User Defined only), End Address: This is the end address that the router
will assign to the computers connected to the router.
Lease Time: The amount of time a network computer will be allowed to connect with the DHCP
Server. By default, the lease time is 2880 minutes.
DHCP Server Reserved Entries: This feature allows you to reserve up to 8 LAN IP Addresses.
These addresses can be assigned to your Servers, so that they always get the same IP Address
when they boot up. Fill up the table by order of ID.
ID: Tick to enable this reservation.

10 PC CONFIGURATION
The Router’s function is to connect multiple PCs to the Internet. In addition to configuring the
Router, the PCs’ IP settings would also need to be configured.
It is easiest to use DHCP client for the PCs. This is also the default whenever you:
a. Install a new Wireless PCMCIA/Cardbus card, or
b. When you plug an Ethernet cable into your PC for the first time.
Fortunately, in default mode, the Router’s DHCP Server is on. This means that when you buy a
new Router and install a new Wireless Card, the IP settings on the PC are already correct!
In the event that you need to troubleshoot the IP settings, the easiest method is:
a. Perform a Hardware Reset to the Router, and
b. Perform a following to configure Automatic IP (DHCP Client) on the PC.
Setting DHCP IP Address
The steps outlined are applicable for Windows PCs. The GUI for Windows 98SE and ME may
look slightly different, but the steps are the same.
1. Connect the PC to the Router. This can be via Ethernet or Wireless. Do not connect
any other networking devices! Do not connect the modem to the PC!
2. Go to Start >> Settings >> Control Panel >> Network and Dial-Up Connections
3. Double-click Local Area Connection.
4. Click on Properties.
Page 37 of 45
5. In the box, click on Internet Protocol (TCP/IP). Make sure there is a tick in the box for
TCP/IP.
6. Use automatic for both the settings. Click OK and close all windows.
7. Windows 98SE and ME may prompt you for a reboot.
DHCP Client has been set up on your PC. Make sure you do a Factory Reset to the Router and
configure your broadband account again.

My IP Address
This section describes how to check your PC’s IP Address. Every PC in your network must have
a unique IP Address. A new Router (or after Factory Reset) would have a default IP Address of
192.168.1.20.
For Win98 and Windows ME Users
To check your PC’s IP Address, go to Start >> Run and type winipcfg
Your PC displays your IP properties in a window:
Your Default Gateway.
Your PC’s subnet mask.
Your PC’s IP Address.
Network Adapter’s
MAC Address.
Choose the
correct
Network device
to view.
For more information, click More Info>>.
It would be good to know your MAC address if you want to implement MAC
address control on your Router.
Page 39 of 45
For Windows 2000 and Windows XP Users
Go to Start >> Run. Type cmd
In the DOS-window, type ipconfig
In this example, we can see that the PC has an IP Address of 192.168.1.21. The Default
Gateway is 192.168.1.20, which is the Router.
For more details, type ipconfig/all.
It would be good to know your MAC address if you want to implement MAC
address control on your Router.
Your Default Gateway is usually the IP Address of the Router: 192.168.1.20

Ping!
Ping is a very useful tool to check network connectivity. Making sure that your PC is physically
plugged into your Router is NOT sufficient! They must also be connected in the networking
sense: their IP settings must be correct. To check if your PC is connected to the Router, you can
perform a Ping to the Router’s IP Address (Usually 192.168.1.20).
When you perform a ping, your PC sends a message to the destination.
If the destination exists, it would receive the message and send a reply back to
you automatically.
If the destination cannot be reached, your PC informs you of the network error.
Go to Start >> Run. Type cmd or command
In the DOS-window, type ping 192.168.1.20.
Destination
IP Address
The connection is good if you are getting replies, as shown above.
Ping also works for a Wireless connection.
But the replies may not be consistent, depending on your distance from the
Router.
Page 41 of 45
If the Ethernet cable is unplugged or if the Wireless LAN settings are wrong, it shows Hardware
error:
If the destination does not exist or cannot be reached because of incorrect IP settings, it would
show Request timed out.
Ping tests are very useful. If the ping is not successful, you may have:
a. Changed the LAN IP of the Router.
b. Turned off the DHCP Server in the Router.
c. Configured a wrong Static Address for your PC.
You would have to:
a. Check the Ethernet cable and/or check the Wireless LAN settings
b. Perform a Factory Reset to the Router if necessary
c. Ensure that your PC is set to DHCP client (automatic).
If you are not even able to ping the Router, there is no way you can access its
Configuration Page.
Page 42 of 45
Web Browser Settings
By default, your Web Browser (eg. Microsoft Internet Explorer, Netscape) does not need any
setup to use the Router. The default settings would allow you to surf the web using the Router.
However, if you have previously used the following methods to access the Internet, you would
need to check your browser settings:
Internal / External 56k modem
ADSL modem connected to your USB port
ADSL dialer software (eg. WinPOET)
Never Dial a Connection
The Web Browser is tied to a particular device for accessing the Internet. This is the reason why
you have to configure it if you had used another networking device previously. The steps are
described for IE6, but the procedure is similar for other Web Browsers.
1. Go to Tools >> Internet Options >> Connections.
2. As seen in the above, the Browser has a Dial-up Connection configured previously.
Choose “Never dial a connection” and Apply. The Browser will now use your LAN
connection (Ethernet or WLAN) to access the Internet instead of the old device.
Page 43 of 45
Proxy Server
Most ISPs do not require you to configure a Proxy Server to surf the Internet. Check with your
ISP. If you are required to configure a Proxy Server, you would have to follow these steps:
1. Continue from the previous page. Click on LAN Settings.
2. Enter the Proxy Server Address and Port number. Do NOT use proxy.com.com!
Check with your ISP!
The Browser would now go through the Proxy Server for every Internet session.
However, the Proxy Server would not be able to direct you to your Router’s
Configuration page (192.168.1.20). Therefore, you have to carry out the next
few steps to make sure that when you want to configure the Router, you go to
192.168.1.20 directly.
3. Click the Advance button.
4. Enter
192.168.1.20 in the box.
5. Click OK on all the windows.
