Fragment Threshold
"Fragment Threshold" specifies the maximum
size of packet during the fragmentation of data
to be transmitted. If you set this value too low, it
will result in bad performance.
RTS Threshold
When the packet size is smaller the RTS
threshold, the wireless router will not use the
RTS/CTS mechanism to send this packet.
Beacon Interval
The interval of time that this wireless router
broadcast a beacon. Beacon is used to
synchronize the wireless network.
Data Rate
The “Data Rate” is the rate this access point
uses to transmit data packets. The access point
will use the highest possible selected
transmission rate to transmit the data packets.
Preamble Type
The “Long Preamble” can provide better
wireless LAN compatibility while the “Short
Preamble” can provide better wireless LAN
performance.
Broadcast ESSID
If you enable “Broadcast ESSID”, every wireless
station located within the coverage of this
access point can discover this access point
easily. If you are building a public wireless
network, enabling this feature is recommended.

Glossary
Default Gateway (Router): Every non-router IP device needs to configure a default gateway’s 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 out towards 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 to the Internet for a preconfigured amount of time, the connection will automatically be 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, that identifies a single, unique Internet
computer host in an IP network. Example: 192.168.2.1. 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 either be 0 or 1.
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 a house or an 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. The MAC address is a unique identifier for a device with an
Ethernet interface. It is comprised of two parts: 3 bytes of data that corresponds 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 of the computers on your home
network to use one IP address. Using the broadband router’s NAT capability, you can access the
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 communications 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
65
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).
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 protocol. 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.
