WPS
Through this process, you can easily add wireless clients to the network without the
need for any specific configuration, such as SSID, security mode or password.
Choose menu “Wireless→WPS”, below given screen will be displayed.
WPS (Wi-Fi Protected Setup) is an easy way to connect to a wireless router.
To use the wizard to add a wireless client to WPS-enabled wireless router, the client
must support WPS.
Check the user manual or the box of the wireless client to confirm whether it supports
the WPS.
If the wireless client does not support WPS, you must configure it manually.
You can add wireless client by PIN mode. If you use PIN mode, you should input
client PIN code. Meanwhile you should start client WPS process. You can find client
PIN code on client manager.

5. Glossary
Default Gateway (Router): Every non-router IP device needs to configure a default
gateway IP address. When the device sends out an IP packet, if the destination is not
on the same network, the device has to send the packet to its default gateway, which
will then send it to the destination.
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives
every computer on your home network an IP address.
DNS Server IP Address: DNS stands for Domain Name System, which allows
Internet servers to have a domain name (such as www.Broadbandrouter.com) and one
or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of
Internet servers and their respective domain names and IP addresses, so that when a
domain name is requested (as in typing "Broadbandrouter.com" into your Internet
browser), the user is sent to the proper IP address. The DNS server IP address used by
the computers on your home network is the location of the DNS server your ISP has
assigned to you.
DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your
existing phone lines to transmit data at high speeds.
Ethernet: A standard for computer networks. Ethernet networks are connected by
special cables and hubs, and move data around at up to 10/100 million bits per
second (Mbps).
Idle Timeout: Idle Timeout is designed so that after there is no traffic on the Internet
for a pre-configured amount of time, the connection will automatically get
disconnected.
IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP address
consists of a series of four numbers separated by periods, which identifies a single,
unique Internet computer host in an IP network. Example: 192.168.1.1. It consists of
2 portions: the IP network address and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four cascaded
decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything
from 000 to 255, or as four cascaded binary numbers separated by “.”:
bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can be either 0 or 1.
Page 80
DG-HR3420 User Manual
80
A network mask is also a 32-bit binary pattern, and consists of consecutive leading
1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can
also be described simply as “x” number of leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP address
that correspond to 1’s in the network mask become part of the IP network address,
and the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.10010000.00000000, and its host ID is,
00000000.00000000.00000000.00000111. This is a convenient and efficient method
for routers to route IP packets to their destination.
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP
address for the Internet router located at the ISP's office.
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the
Internet for individuals and other businesses or organizations.
LAN: Local Area Network. A LAN is a group of computers and devices connected
together in a relatively small area (such as home or office). Your home network is
considered a LAN.
MAC Address: MAC stands for Media Access Control. A MAC address is the
hardware address of a device connected to a network. MAC address is a unique
identifier for a device with an Ethernet interface. It is comprised of two parts: 3 bytes
of data that correspond to the Manufacturer ID (unique for each manufacturer), plus 3
bytes that are often used as the product’s serial number.
NAT: Network Address Translation. This process allows all the computers on your
home network to use one IP address. Using the broadband router’s NAT capability,
you can access Internet from any computer on your home network without having to
purchase more IP addresses from your ISP.
Port: Network Clients (LAN PC) uses port numbers to distinguish one network
application/protocol over another. Below is a list of common applications and
protocol/port numbers:

PPPoE: (Point-to-Point Protocol over Ethernet.) Point-to-Point Protocol is a secure
data transmission method originally created for dial-up connections; PPPoE is for
Ethernet connections. PPPoE relies on two widely accepted standards, Ethernet and
the Point-to-Point Protocol. It is a communication protocol for transmitting
information over Ethernet between different manufacturers.
Protocol: A protocol is a set of rules for interaction agreed upon between multiple
parties so that when they interface with each other based on such a protocol, the
interpretation of their behavior is well defined and can be made objectively, without
confusion or misunderstanding.
Router: A router is an intelligent network device that forwards packets between
different networks based on network layer address information such as IP addresses.
Subnet Mask: A subnet mask, which may be a part of the TCP/IP information
provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an
IP address. It is used to create IP address numbers used only within a particular
network (as opposed to valid IP address numbers recognized by the Internet, which
must be assigned by InterNIC).
Page 82
DG-HR3420 User Manual
82
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and
Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data
transmission over the Internet. Both TCP and UDP are transport layer protocols. TCP
performs proper error detection and error recovery, and thus is reliable. UDP on the
other hand is not reliable. They both run on top of the IP (Internet Protocol), a
network layer protocol.
WAN: Wide Area Network. A network that connects computers located in
geographically separate areas (e.g. different buildings, cities, countries). The Internet
is a wide area network.
Web-based management Graphical User Interface (GUI): Many devices support a
graphical user interface that is based on the web browser. This means the user can use
the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor
the device being managed.
