802.11b or 802.11g
802.11b networks can operate at a
maximum of 11Mbits per second. 802.11g
networks operate at up to 54Mbits per
second.
Access Point
Also known as a wireless router, an access
point forms the heart of your wireless
network and controls its security
configuration. If you are using an access
point, you have an Infrastructure mode
network.
Ad-Hoc
Each device communicates directly with
each device. There is no central access
point controlling wireless network
communication. This type of network is
also referred to as a Peer-to-peer wireless
network.
APIPA
Automatic Private IP Addressing (APIPA) is
used when your network device is not able
to obtain an IP address from a DHCP
server.
ASCII
American Standard Code for Information
Interchange (ASCII). The numerical
representation of a character. For
example, the ASCII code for the letter A is
65.
Authentication Method
The type of wireless authentication used
on your network.
Channel
Wireless networks use channels. Each
channel uses a different radio frequency in
a pre-determined range. All wireless
devices within the wireless network will
use the same channel unless those devices
are connected to other wireless access
points that act as a gateway to the
wireless network.

DHCP
A Dynamic Host Configuration Protocol
(DHCP) server allocates IP addresses to
network devices.
DSL
Digital Subscriber Line (DSL) also referred
to as ADSL or xDSL. A high-speed internet
connection.
EAP
Extensible Authentication Protocol (EAP)
that provides an authentication framework
for wireless and wired networks. EAP uses
a RADIUS server, which authenticates
users on corporate networks before they
are allowed to access the wireless or wired
network.
Network cable (Ethernet cable)
The cable used to connect your device to
your wired network. Ethernet cables use a
RJ45 connectors and the cable itself is also
known as a straight-through cable.
Gateway Address
A gateway address allows the device to
communicate with other devices on
different networks. Generally speaking,
you do not need to configure a gateway
address.
HEX
Short for HEXADECIMAL, a numbering
system that uses the numbers 0-9 and the
letters A-F.
Infrastructure
Each device communicates via a central
access point. This is the most commonly
used type of wireless network.
IP Address
Each device on the network must use a
unique address. This address is known as
an IP address and must be entered
manually or can be automatically assigned
using a DHCP server. An IP address is a
mandatory in a TCP/IP network.
LEAP
Lightweight Extensible Authentication
Protocol (LEAP) A Cisco protocol used for
802.1X authentication on wireless LANs.
Like EAP, LEAP uses a RADIUS server,
which authenticates users on corporate
networks before they are allowed to
access the wireless or wired network.
MAC Address

Glossary
A Media Access Control (MAC) address is
unique 12-digit number assigned to each
network device.
Node Name
A unique name for the wireless device.
Generally speaking, the node name is
based on the MAC address.
Signal Strength
The strength of the wireless signal
between your device and the access point
you are communicating with.
Subnet Mask.
An IP address also requires a subnet
mask. The subnet mask is entered
manually, or assigned automatically if
using a DHCP server. A subnet mask is
mandatory in a TCP/IP network.
SSID
The Service Set Identifier (SSID), also
referred to as the network name, is the
name that your wireless network uses. On
some wireless networks, the SSID name is
not advertised to increase security.
Switch
A switch makes it possible for several
network devices to communicate with each
other.
TKIP
TKIP (Temporal Key Integrity Protocol)
removes the predictability that intruders
could relied upon to exploit security
weaknesses brought about with the use of
manually assigned WEP keys. TKIP keys
are automatically generated and are
longer that WEP keys and as a result,
more secure that standard WEP keys.
WEP Key
The Wireless Equivalent Protocol (WEP)
key is a basic wireless security feature
that protects your wireless network from
casual eavesdroppers. A WEP key is also
referred to as a Network Key.
