all devices connected to the wireless network must share the same security settings.
Basic > Advanced > Admin > Status > Shortcuts > Help
•SSID: (Default at&t) The Service Set Identifier is the name of your wireless local area network. The
factory default name is "at&t". For privacy, you should change this to a unique name. If you leave the
default name, users of other wireless networks nearby may have access to your computers or your
Internet access (if they are using the same SSID). Remember that all computers on your network
must share the same SSID.
•Channel: (Default 6) The router uses radio signals to communicate with other devices on the network.
You can change the frequency by selecting a different channel. Remember that all computers on your
network must use the same channel. Devices using AT&T Plug&Share™wireless adapters will auto-
matically detect the channel used by the router and change to it.
You may have to change the channel if you are experiencing problems such as intermittent connec-
tion and disconnection. You can perform a site survey on your wireless adapter to find out which
channels are being used by other wireless networks nearby. If other networks use the same channel
(or an adjacent one), change yours to one as far away as possible from the others in use. (For example,
if other networks use channels 6, 9 and 11, try changing yours to channel 1.)

Glossary
AT&T Plug&Share™54 Mbps Wireless Router 6800G 71
Access Point
Access points are the contact points (wireless
routers and transmitters) in a wireless LAN that
are connected to an Ethernet hub or server.
Users can roam within the range of access points
and their wireless device connections are passed
from one access point to the next.
Administrator
The network administrator is the person who
manages the LAN. The administrator's tasks
include ensuring network security, keeping soft-
ware, hardware, and firmware up-to-date, and
keeping track of network activity. Your router
Administrator is the person in control of access to
your router. The system starts out with all users
as administrators.
Authentication
Authentication refers to the verification of a
transmitted message's integrity.
Beacon Interval
Refers to the interval between packets sent by
routers for the purposes of synchronizing wireless
LANs.
Broadband
Usually refers to Internet connections that provide
faster data transfer than standard dial-up
connections (cable modem, DSL, T-1, etc.)
DDNS
Dynamic DNS (Domain Name System).
DHCP
DHCP (Dynamic Host Configuration Protocol) soft-
ware automatically assigns IP addresses to client
stations logging onto a TCP/IP network, which
eliminates the need to manually assign permanent
IP addresses.
DHCP Client
The DHCP client list shows all of the computers
attached to your local network. The list shows the
host name of the computer.
DMZ
DMZ (Demilitarized Zone) is a part of an network
that is located between a secure LAN and an
insecure WAN. DMZs provide a way for some
clients to have unrestricted access to the Internet.
DNS
DNS stands for Domain Name System. DNS
converts domain names to the IP addresses that
all machines on the Internet have. It translates
from name to address and from address to name.
Domain Name
The domain name is the "readable" version of an
Internet site address. A typical domain name has
the form "www.somedomainname.com" or
"www.somedomainname.org", etc.
DTIM
DTIM (Delivery Traffic Indication Message) pro-
vides client stations with information on the next
opportunity to monitor for broadcast or multicast
messages.
Filter
Filters only allow specified data to be transmitted
or received. For example, the router can filter
specific IP addresses so that users cannot con-
nect to those addresses.
Firewall
Firewalls are methods used to keep networks
secure from intruders and unauthorized access.
Firewalls use filters to prevent unwanted data
from being transmitted to and/or from a local net-
work. Firewalls are typically used to prevent out-
siders from accessing your private data
resources and for controlling what outside (WAN)
resources your users can access.
Firmware
Firmware refers to memory chips that retain their
content without electrical power (for example,
BIOS ROM). The router firmware stores all of the
router administration settings.
Fragmentation
Refers to the breaking up of data packets during
transmission.
FTP
FTP (File Transfer Protocol) is used to transfer
files over a TCP/IP network, and is typically used
for transferring large files or uploading the HTML
pages for a web site to the web server.
Glossary
Glossary
AT&T Plug&Share™54 Mbps Wireless Router 6800G 72
Gateway
Gateways are computers that convert protocols
enabling different networks, applications, and
operating systems to exchange information.
Host Name
The name given to a computer or client station
that acts as a source for information on the
network.
HTTP
HTTP (HyperText Transfer Protocol) is the com-
munications protocol used to connect to servers
on the World Wide Web. HTTP establishes a
connection with a web server and transmits
HTML pages to client browser (for example
Windows®IE). HTTP addresses all begin with the
prefix “http://” (for example,
http://www.somedomainname.com).
ICMP
ICMP (Internet Control Message Protocol) is a
TCP/IP protocol used to send error and control
messages over the LAN (for example, it is used
by the router to notify a message sender that the
destination node is not available).
IP
IP (Internet Protocol) is the protocol in the TCP/IP
communications protocol suite that contains a
network address and allows messages to be
routed to a different network or subnet. However,
IP does not ensure delivery of a complete message;
TCP provides the function of ensuring delivery.
IP Address
The IP (Internet Protocol) address refers to the
address of a computer attached to a TCP/IP net-
work. Every client and server station must have a
unique IP address. Clients are assigned either a
permanent address or have one dynamically
assigned to them via DHCP. IP addresses are
written as four sets of numbers separated by
periods (for example, 211.23.181.189).
ISP
An ISP (Internet Service Provider) is an
organization providing Internet access service via
modems, ISDN (Integrated Services Digital
Network), private lines or other means.
LAN
LANs (Local Area Networks) are networks that
serve users within specific geographical areas,
such as your home or in a company building.
LANs consist of a group of computers and related
devices that share a common communication link
(wired and/or wireless). A LAN allows you to
share data and resources among the devices on
the LAN.
MAC Address
A MAC address is a unique serial number for
hardware adapters, giving the adapter a unique
identification.
Metric
A number that indicates how long a packet takes
to get to its destination.
MTU
MTU (Maximum Transmission/Transfer Unit) is
the largest packet size that can be sent over a
network. Messages larger than the MTU are
divided into smaller packets.
NAT
NAT (Network Address Translation — also known
as IP masquerading) enables a LAN to present
itself to the Internet with one address. NAT con-
verts the address of each LAN node into one IP
address for the Internet (and vice versa). NAT also
provides a certain amount of security by acting as
a firewall by keeping individual IP addresses
hidden from the WAN.
Network Administrator
The network administrator is the person who man-
ages the LAN. The administrator's tasks include
ensuring network security, keeping software, hard-
ware, and firmware up-to-date, and keeping track
of network activity.
NTP
NTP (Network Time Protocol) is used to synchro-
nize the realtime clock in a computer. Internet pri-
mary and secondary servers synchronize to
Coordinated Universal Time (UTC).
Open System
Open authentication allows all clients to connect
to the network. After accessing the network, the
client may encrypt data to prevent it from being
easily seen by other users in the immediate area.
Glossary
AT&T Plug&Share™54 Mbps Wireless Router 6800G 73
Packet
A packet is a portion of data that is transmitted in
network communications. Packets are also
sometimes called frames and datagrams.
Packets contain not only data, but also the
destination IP address.
Passphrase
A Passphrase is used within the WPA-PSK mode
to enable a client to initiate authentication with a
router. If the passphrase is identical to the
passphrase on the router, the router allows the
client to access the network. The passphrase can
be between 8 and 63 characters.
Ping
Ping (Packet Internet Groper) is a utility used to
find out if a particular IP address is present online.
Port
Ports are the physical and/or logical communica-
tions pathways in and out of computers and net-
work devices (routers and switches). Most PCs
have serial and parallel ports, which are external
sockets for connecting devices such as printers,
modems, and mice. All network adapters also
use ports to connect to the LAN. Finally, applica-
tions that communicate over the Internet also
have ports; these are the endpoints of the appli-
cation and are given a specific "port number."
PPPoE
PPPoE (Point-to-Point Protocol Over Ethernet) is
a protocol used to communicate between two
computers using a serial interface, such as dial-
up Internet connections, over an Ethernet link.
Preamble
The Preamble Type refers to the radio preamble,
or header, which is transmitted at the beginning
of a packet of data. The preamble contains infor-
mation required for the access point and
adapters to transmit information. Since the
Preamble is attached to each packet of data, a
Short Preamble improves data throughput, but it
may cause connection problems with early wire-
less devices that only support long preambles.
The Long Preamble option ensures compatibility
with these early wireless devices.
Protocol
A protocol is a rule that governs the communica-
tion of data.
Radius Server
RADIUS (Remote Authentication Dial-in User
Service) Server must be configured to properly
authenticate client devices for access to the net-
work. The IP address and port number are based
on the configuration of the RADIUS server in your
enterprise network. The shared secret is a pass-
word that is used to identify the client in a
RADIUS authenticated network. The shared
secret can be from 22 to 128 characters long.
RIP
RIP (Routing Information Protocol) is a routing
protocol that is integrated in the TCP/IP protocol.
RIP finds a route that is based on the smallest
number of hops between the source of a packet
and its destination.
RTS
RTS (Request To Send) is a signal sent from the
transmitting station to the receiving station
requesting permission to transmit data.
Security Phrase
At least 1 and up to 4 unique Security Phrases
must be set when WEP is "On." The encryption
types for these Security Phrases may be either
Hexadecimal (HEX) or American Standard Code
for Information. Interchange (ASCII). ASCII
Security Phrases are subject to the following
character limitations: 64 Bit encryption: 5 charac-
ters; 128 Bit encryption: 13 characters; 152 Bit
encryption: 16 characters.
Server
Servers are typically powerful and fast computers
that store programs and data. The programs and
data are shared by client computers (worksta-
tions) on the network.
Shared Key
Shared Key authentication requires the client to
use the same WEP encryption key as that used
by the wireless router. When the client attempts
to connect to the network through the wireless
router the router sends a challenge text message
to the client to authenticate the client. The client
returns the challenge text message encrypted
using the WEP encryption key. The wireless
router decrypts the message using it's WEP key
and if the decrypted message is the same as the
original challenge text message, then it is
assumed that the client has the correct WEP key
and the client is allowed to access the network.

SMTP
SMTP (Simple Mail Transfer Protocol) is the stan-
dard Internet e-mail protocol. SMTP is a TCP/IP
protocol defining message format and includes a
message transfer agent that stores and forwards
mail.
SNMP
SNMP (Simple Network Management Protocol) is
a widely used network monitoring and control
protocol. SNMP hardware or software components
transmit network device activity data to the work-
station used to oversee the network.
SSID
SSID (Service Set Identifier) is the name desig-
nated for a LAN. It serves as a simple security
measure used in Wireless LANs (WLANs). The
SSID is attached to packets sent over WLANs.
This identifier acts as a password when a wire-
less device attempts communication on the
WLAN. Because an SSID distinguishes WLANS
from each other, routers and wireless devices
trying to connect to a WLAN must use the same
SSID.
Subnet Mask
Subnet Masks (SUBNETwork masks) are used
by IP protocol to direct messages into a specified
network segment (i.e., subnet). A subnet mask is
stored in the client machine, server or router and
is compared with an incoming IP address to
determine whether to accept or reject the packet.
SysLog Server
A SysLog server monitors incoming System log
messages and decodes the messages for logging
purposes.
TCP
(Transmission Control Protocol) is the transport
protocol in TCP/IP that ensures messages over
the network are transmitted accurately and
completely.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet
Protocol) is the main Internet communications
protocol suite. TCP ensures that data is com-
pletely sent and received at the other end. The IP
component of TCP/IP provides data routability,
meaning that data packets contain the destination
station and network addresses, enabling TPC/IP
messages to be sent to multiple networks within
the LAN or in the WAN.
Telnet
Telnet is a terminal emulation protocol commonly
used on the Internet and TCP- or IP-based net-
works. Telnet is used for connecting to remote
devices and running programs. Telnet is a high
level application protocol that uses the TCP/IP
communications protocol.
UDP
(User Datagram Protocol) is a protocol within
TCP/IP that is used to transport information when
accurate delivery isn't necessary (for example,
realtime video and audio where packets can be
dumped since there is no time for retransmitting
the data).
Virtual Servers
Virtual servers are client servers (such as web
servers) that share resources with other virtual
servers (i.e., it is not a dedicated server).
VoIP
(Voice Over Internet Protocol) is a method used
to deliver voice information over the Internet.
VoIP services allow telephone calls using your
PC or LAN.
WEP
WEP (Wired Equivalent Privacy) is the most com-
mon security protocol for wireless LANs, provid-
ing the "equivalent" security available in hard-
wired networks.

Wireless LAN (WLAN)
Wireless LANs are local area networks that use
wireless communications for transmitting data.
Transmissions are usually in the 2.4 GHz band.
WLAN devices do not need to be lined up for
communications like infrared devices. WLAN
devices use routers which are connected to the
wired LAN and provide connectivity to the LAN.
The radio frequency of WLAN devices is strong
enough to be transmitted through non-metal walls
and objects, and can cover an area up to a
thousand feet. Laptops and notebooks use wire-
less LAN PCMCIA cards while PCs use plug-in
cards to access the WLAN.
WAN
WAN (Wide Area Network) is a communications
network that covers a wide geographic area such
as a country (contrasted with a LAN, which
covers a small area such as a company building).
WPA
WPA (WiFi Protected Access) is an enhanced
security specification to increase the level of
access control and data protection for wireless
data networks. WPA authentication requires that
an authentication server authenticate all client
adapters before being allowed access to a wire-
less network. This authentication mode is
designed for enterprise applications requiring
very high levels of security.
WPA-PSK
Authentication mode enables the user to
configure a type of client authentication used for
acquiring access to the wireless network. The
WPA-PSK mode has been designed for those
environments where high data security is desired,
but there is no authentication server. The client
initiates authentication by sending a password
called a passphrase to the wireless router. If the
passphrase is identical to the passphrase on the
wireless router, the wireless router allows the
client to access the network. The passphrase can
be between 8 and 63 characters.
