Cloning Mode
This feature controls the MAC Address of the
Bridge as seen by other devices (wired or wireless).
If set to “Ethernet Client”, the MAC Address from
the first Ethernet client that transmits data through
the Bridge will be used. This setting is useful when
connected to an Xbox or if there is only one
Ethernet device connected to the bridge. When
multiple Ethernet devices are connected to the
Bridge, it may not be obvious which MAC Address is
being used.
If set to “WLAN Card”, the MAC Address of the
WLAN Card (typically written on the back of the
card) will be used. When multiple Ethernet devices
are connected to the Bridge, the MAC Address of
the Bridge will not change.
Fragmentation threshold
Transmitted wireless packets larger than this size
will be fragmented to maintain performance in noisy
wireless networks.
RTS threshold
Transmitted wireless packets larger than this size
will use the RTS/CTS protocol to (a) maintain
performance in noisy wireless networks and (b)
prevent hidden nodes from degrading performance.
Maximum burst time
This is also known as PRISM Nitro (tm)
technology. The technology uses fully standardscompliant methods that eliminate collisions in mixed17
mode networks, while greatly increasing the
performance of both pure
802.11g and mixed
802. 11b/g networks. The setting is for the amount
of time the radio will be reserved to send data
without requiring an ACK.
This number is in units of microseconds. The
optimized value for 802.11g only networks is 1400,
and the optimized value for 802.11g + 802.11b
mixed mode networks is 650. When this number is
zero, bursting is disabled.

Appendix II Glossary
802.11 standard
802.11, or IEEE 802.11, is a type of radio technology used for
wireless local area networks (WLANs). It is a standard that has
been developed by the IEEE (Institute of Electrical and Electronic Engineers), http://standards.ieee.org. The IEEE is an international organization that develops standards for hundreds of
electronic and electrical technologies. The organization uses a
series of numbers, like the Dewey Decimal system in libraries, to
differentiate between the various technology families.
The 802 subgroup (of the IEEE) develops standards for local
and wide area networks with the 802.11 section reviewing and
creating standards for wireless local area networks.
Wi-Fi , 802.11, is composed of several standards operating in
different radio frequencies: 802.11b is a standard for wireless
LANs operating in the 2.4 GHz spectrum with a bandwidth of 11
Mbps.
Another standard, 802.11g, is for WLANS operating in the 2.4 GHz
frequency but with a bandwidth of 54 Mbps.
26
802.11b
International standard for wireless networking that operates
in the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and
provides a throughput of up to 11 Mbps. This is a very commonly
used frequency. Microwave ovens, cordless phones, medical and
scientific equipment, as well as Bluetooth devices, all work within
the 2.4 GHz frequency band.
802.11g
Similar to 802.11b, but this standard provides a throughput of
up to 54 Mbps. It also operates in the 2.4 GHz frequency band
but uses a different radio technology in order to boost overall
bandwidth.
Access point
A wireless LAN transceiver or “base station” that can connect a
wired LAN to one or many wireless devices. Access points can
also bridge to each other.
There are various types of access points and base stations
used in both wireless and wired networks. These include bridges,
hubs, switches, routers and gateways. The differences between
them are not always precise, because certain capabilities associated with one can also be added to another. For example, a
router can do bridging, and a hub may also be a switch. But
they are all involved in making sure data is transferred from one
location to another.
A bridge connects devices that all use the same kind of protocol.
A router can connect networks that use differing protocols. It
also reads the addresses included in the packets and routes
them to the appropriate computer station, working with any other
routers in the network to choose the best path to send the packets on. A wireless hub or access point adds a few capabilities
27
such as roaming and provides a network connection to a variety
of clients, but it does not allocate bandwidth. A switch is a hub
that has extra intelligence: It can read the address of a packet
and send it to the appropriate computer station. A wireless gateway is an access point that provides additional capabilities such
as NAT routing, DHCP, firewalls, security, etc.
AES (Advanced Encryption Standard)
A chip-based security, has been developed to ensure the
highest degree of security and authenticity for digital information,
wherever and however communicated or stored, while making
more efficient use of hardware and/or software than previous
encryption standards. It is also included in IEEE 802.11i standard.
Compared with AES, TKIP is a temporary protocol for replacing
WEP security until manufacturers implement AES at the hardware level.
DHCP
Dynamic Host Configuration Protocol. This protocol automatically configures the TCP/IP settings of every computer on your
home network.
Encryption key
An alphanumeric (letters and/or numbers) series that enables
data to be encrypted and then decrypted so it can be safely
shared among members of a network. WEP uses an encryption
key that automatically encrypts outgoing wireless data. On the
receiving side, the same encryption key enables the computer to
automatically decrypt the information so it can be read.
Ethernet
A standard for computer networks. Ethernet networks are con28
nected by special cables and hubs, and move data around at up
to 100 million bits per second (Mbps).
ESSID
The identifying name of an 802.11 wireless network. When
you specify your correct ESSID in your client setup you ensure
that you connect to your wireless network rather than another
network in range. (See SSID.) The ESSID can be called by different terms, such as Network Name, Preferred Network, SSID
or Wireless LAN Service Area.
Gateway
In the wireless world, a gateway is an access point with additional software capabilities such as providing NAT and DHCP.
Gateways may also provide VPN support, roaming, firewalls,
various levels of security, etc.
IEEE802.11
A set of specifications for LANs from The Institute of Electrical
and Electronics Engineers (IEEE). Most wired networks conform to 802.3, the specification for CSMA/CD based Ethernet
networks or 802.5, the specification for token ring networks.
802.11 defines the standard for wireless LANs encompassing
three incompatible (non-interoperable) technologies: Frequency
Hopping Spread Spectrum (FHSS), Direct Sequence Spread
Spectrum (DSSS) and Infrared. WECA’s focus is on 802.11b, an
11 Mbps high-rate DSSS standard for wireless networks.
IP Address
IP stands for Internet Protocol. An IP address consists of a
series of four numbers separated by periods, that identifies an
single, unique Internet computer host. Example: 192.34.45.8.
29
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. This address is required only
when using a cable or DSL modem.
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
Every wireless 802.11 device has its own specific MAC address hard-coded into it. This unique identifier can be used to
provide security for wireless networks. When a network uses a
MAC table, only the 802.11 radios that have had their MAC addresses added to that network’s MAC table will be able to get
onto the network.
MAC Address
MAC stands for Media Access Control. A MAC address is the
hardware address of a device connected to a network.
Peer-to-peer network
A wireless or wired computer network that has no server or
central hub or router. All the networked PCs are equally able to
act as a network server or client, and each client computer can
talk to all the other wireless computers without having to go
through an access point or hub. However, since there is no central base station to monitor traffic or provide Internet access, the
30
various signals can collide with each other, reducing overall
performance.
SSID
A 32-character unique identifier attached to the header of
packets sent over a WLAN that acts as a password when a mobile device tries to connect to the BSS. (Also called ESSID.) The
SSID differentiates one WLAN from another, so all access points
and all devices attempting to connect to a specific WLAN must
use the same SSID. A device will not be permitted to join the
BSS unless it can provide the unique SSID. Because an SSID can
be sniffed in plain text from a packet, it does not supply any
security to the network. An SSID is also referred to as a Network
Name because essentially it is a name that identifies a wireless
network.
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 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.
TCP/IP
Transmission Control Protocol/Internet Protocol. This is the
standard protocol for data transmission over the Internet.
TKIP
The TKIP (Temporal Key Integrity Protocol), pronounced teekip, is part of the IEEE 802.11i encryption standard for wireless
LANs. TKIP is the next generation of WEP used to secure 802.11
wireless LANs.TKIP provides per-packet key mixing, a message
31
integrity check and a re-keying mechanism, thus fixing the flaws
of WEP.
WAN
A wide area network (WAN) is a geographically dispersed
telecommunications network. The term distinguishes a broader
telecommunication structure from a local area network. A wide
area network may be privately owned or rented, but the term
usually connotes the inclusion of public (shared user) networks.
An intermediate form of network in terms of geography is a
metropolitan area network .
WEP
WEP (Wired Equivalent Privacy) is 802.11’s optional encryption standard implemented in the MAC layer that most radio
network interface card (NIC) and access point vendors support.
Basic wireless security provided by Wi-Fi. In some instances,
WEP may be all a home or small-business user needs to protect
wireless data. WEP is available in 40-bit (also called 64-bit), or in
108-bit (also called 128-bit) encryption modes. As 108-bit encryption provides a longer algorithm that takes longer to decode,
it can provide better security than basic 40-bit (64-bit) encryption.
Wi-Fi
An interoperability certification for wireless local area network (LAN) products based on the Institute of Electrical and
Electronics Engineers (IEEE) 802.11 standard.
WLAN
Also referred to as LAN. A type of local-area network that uses
high-frequency radio waves rather than wires to communicate
between nodes.
32
WPA
WPA is a standards-based, interoperable security specification
that utilizes Temporal Key Integrity Protocol to provide improved over-the-air encryption of wireless data.
33
In order to maintain compliance with the FCC RF exposure
guidelines, this equipment shouldbe installed and operated with
minimum distance 20cm between the radiator and your
body.Use only with supplied antenna. Unauthorized antenna,
modification, or attachments could damage the transmitter and
may violate FCC regulations.
