5. Installing the Hardware
5.1. Before Installing
The user’s MODEM should be plugged into the power after configuring the
DosaLink – 540.
In the case of an Automatic connection MODEM among Asymmetric Digital
Subscriber Line (ADSL) MODEM users, “Cable, VDSL” should be selected in the
“WAN Setup” menu on the DosaLink – 540’s configuration window.
The Automatic connection MODEM has built-in “user account” and “password”,
which are required to authenticate the PPPoE, so it may be able to connect to
the Internet without any connection program.

User’s Manual 9/73
Ver. [E.1.1]
5.2. Connecting the Cables
Connecting LAN port(s) of the Ethernet to WAN port of the DosaLink – 540.
Since WAN port of the DosaLink -540 have built-in AUTO DI/MDI function, either
a direct cable or cross cable can be used.
Connecting LAN port(s) of the DosaLink -540 to corresponding user’s PC.Since
LAN port of the DosaLink – 540 have built-in AUTO MDI/MDIX function, either a
direct cable or cross cable can be used.
Figure 3 Example of connecting cables
5.3. Configuration Information
The following information is required for configuring the DosaLink -540:
Type of broadband (ADSL, VDSL, Cable, Static IP).
“User Name (Login Name)” and “Password” for ADSL user.
In the case of a Static IP Address: IP Address, Subnet Mask, Gateway, DNS
Server Address, etc.
5.4. Factory Default Setting
LAN interface IP: 192.168.1.1
DHCP: Server
Assigned IP Address of DHCP Server: 192.168.1.2 ~ 254
WAN: Cable, VDSL/ Dynamic IP

SSID: nDOSA
Channel: 6
User ID: root
User Password: admin
Wireless Encryption: nESA with Default Key
6. Configuring the computer for sharing the Internet
For sharing the Internet through the DosaLink – 540, the computer should be
configured while the communication between the user’s PC and DosaLink – 540
is normal.
Since LAN IP of the DosaLink – 540 is 192.168.1.1, the user’s PC should have
the following network IP address – 192.168.1.2 ~ 254 – for connecting to the
DosaLink – 540.
There are two ways to assign IP Address to user’s PC. First, the user’s PC
obtains an IP address automatically from the Dosalink – 540 assigned IP address.
Second, the IP address can be assigned by the user. However, a static IP
address should be assigned for operating servers such as Web, FTP, etc.
Configuring the user’s PC may vary depending on the Operating System (OS)
being utilized. This manual is written for users of Windows 2000 and XP.
6.1. Configuration for Windows 2000 and XP
6.1.1. Obtain an IP address automatically for DosaLink – 540
1. “Control Panel” => “Network Connections” => “Local Area Connection” =>
“General” => click “Properties”, and then Figure 4 pops up. In this “Local Area
Connection Properties” window, select “TCP/IP” and click “Properties”.
2. In the “Internet Protocol (TCP/IP) Properties” window, select “obtain an IP
address automatically” and “obtain DNS server address automatically” as
shown in Figure 5. Then, click “OK” to save the configuration.

6.1.2. Confirm and Renew the IP address
The saved configuration information may be confirmed by using the “ipconfig”
command in the DOS window.
1. Select “Start” => “Run” and input “cmd”. Then, click “OK” to execute the DOS
window.
Figure 6 “Run” Window
2. The IP address, Subnet Mask, and Gateway that are assigned automatically
should be confirmed with inputting the command “ipconfig” on the DOS
window. If it is normal, then the IP address should be assigned
“192.168.1.xxx” as shown in Figure 7.
Figure 7 DOS Window (“ipconfig”)
3. If the assigned IP address is outscope of “192.168.1.xxx, then it should be
renewed by “ipconfig /release” and “ipconfig /renew” commands as shown in
Figure 8.

Ver. [E.1.1]
Figure 8 DOS WIndow (ipconfig / release & ipconfig /renew)
4. If the assigned IP address is an outscope of “192.168.1.xxx” or it has failed to
get an IP address even though the above steps for getting an IP address
were excuted, then the static IP address should be assigned by the user with
regard to the following section.
6.1.3. Assign the static IP address
This section explains how to assign the static IP address to the user’s PC when
the DosaLink – 540 cannot assign an IP address to the user’s PC or a server is
operating on the network.
1. “Control Panel” -> “Network Connections” -> “Local Area Connection” ->
“General” -> click “Properties”, and then Figure 9 pops up. In this “Local Area
Connection Properties” window, select “TCP/IP” and click “Properties”.
2. In the “Internet Protocol (TCP/IP) Properties” window, select “Use the
following IP address” and “Use the following DNS server addresses” as
shown in Figure 10. Then, input the correct addresses and click “OK” to save
the configuration.

Ver. [E.1.1]
Figure 9 “Local Area Connection Properties” window
3. If several user’s PCs need to be assigned IP addresses, then the information
for Subnet Mask, Gateway, and DNS server should be the same and the IP
address should be selected between 192.168.1.2 and 192.168.1.254.

7. Communication between user’s PC and the DosaLink – 540
The communication between the user’s PC and the DosaLink - 540 should be
confirmed before configuring the PC by utilizing the configuration window of the
DosaLink – 540. For this purpose the “ping” command can be used.
“Start” => “Run”, input “cmd” and press “OK”. The DOS window will be open.
Once performed “ping 192.168.1.1”, should appear as shown as Figure 11. If it
does not appear, then the sequence should be performed again after pressing
“reset”, which is located on the back of the DosaLink -540, and rebooting the
user’s PC.

8. Connect the Internet via the configuration window of DosaLink – 540
1. First, run the web browser to connect to the Internet. However, it is not
connected to the Internet because the DosaLink – 540 is not configured yet. On
the web browser’s menu, select “tools” => “Internet options...”.
