Chapter 2.Hardware Installation Guide
The TD-8841 maintains six separate interfaces, including four Ethernet interfaces, one USB
interface and one ADSL interface. The Router should not be located where it will be exposed to
moisture or excessive heat. Place the Router in a location where it can be safely connected to the
various devices as well as to a power source.
2.1 System requirement
Confirm your computer has been installed with networking interface card (NIC) before connecting
ADSL2+ Router to your computer, with the operating system supporting the TCP/IP protocol.

Chapter 3.System Configuration
3.1 Computer Configuration
The default IP address of the ADSL2+ Router is 192.168.1.1, and the default Subnet Mask is
255.255.255.0. These values can be seen from the LAN, and can be changed as your desire. As
an example, we use the default values for description in this guide.
1. Connect the cable according to Chapter 2, turn on the power.
2. Connect the local PCs to the ADSL2+ Router’s LAN port. There are then two means to
configure the IP address for your PCs.
¾
Configure the IP address manually
1) Set up the TCP/IP Protocol for your PC(s).
2) Configure the network parameters. The IP address is 192.168.1.xxx ("xxx" is from 2 to
254), Subnet Mask is 255.255.255.0, and Gateway is 192.168.1.1 (The ADSL2+
Router’s default IP address).
¾
Obtain an IP address automatically
1) Set up the TCP/IP Protocol in "Obtain an IP address automatically" mode on your
PC(s).
2) The built-in DHCP server will assign IP addresses for the PC(s).
Note:
)
Remarks: you can check whether your configuration is successful through PING command. Enter
Ping 192.168.1.1
If the screen looks like the following, you have been successful.
If the screen looks like the following, the connection has failed. Please try again.

Chapter 5.FQA
1. What related parameters are required to acquire ISP when you want to access the
internet by ADSL2+ Router?
1) Dial user: Connection protocol, User name, Password, Value of VPI/VCI, Encapsulation
mode of AAL5 and so on.
2) Static IP user: Connection protocol, WAN IP Address, Subnet Mask, Gateway, Value of
VPI/VCI, Encapsulation mode of AAL5 and so on.
2. About Connection protocol, VCI/VPI, Encapsulation mode of AAL5
1) This product supports the PPP protocol over ATM (PPPoA)、PPP over Ethernet
(PPPoE)、MAC Encapsulation Routing (MER)、IP over ATM (IPoA) and Bridging. You
may be used with any one of the five protocols above. Because the ISP in different areas
supports different protocol, you must choose the protocol which is supported by your
ISP.
2) The VPI is the English abbreviation of the Virtual Path Identifier, the VCI is the English
abbreviation of the Virtual Channel Identifier, the value of VCI/VPI must be compatible
with the value that provided by ISP.
3) Encapsulation mode of AAL5 include: LLC/SNAP and VC_MAX (often using
LLC/SNAP).
3. Why the LAN’s and the NIC’s LED both bright, but the configuration interface is
inaccessible?
1) Use the order of ping 192.168.1.1 to check the Accuracy of connection.
2) Check the Accuracy of working NIC.
3) Whatever the setup of the IP address on your computer (if you close the DHCP function,
you can't obtain the IP address automatically, must specify the IP address of your
computer manually).
4) Run the winipcfg order in the windows 95/98(run the ipconfig order in the windows
2000/Vista) to check whether setup the IP address, subnet mask, default gateway by
DHCP.
5) Resume the ADSL2+ Router default configuration if necessary.
4. Have completed all configurations, but can’t dial through computer
1) Check the indicator of ADSL2+, it should be working normally.
2) Check the accuracy of parameter of value of VPI/VCI, Encapsulation mode of AAL5 and
so on, whether you need to install the software of dial the number, such as Winpoet,
Enternet.
3) This product has the PPP dial procedure inside, so you will not need to use the dial
software if your protocol is PPPoA or PPPoE, ADSL2+ Router will connect automatically.
4) You can check whether your ADSL2+ Router succeeds in connection with PING
command.
