Important Notice: In order to make the correct use of the WPA,
make sure that your current wireless router’s driver, and Wireless
Utility can support the WPA. The WPA needs 802.1x authentication
(when RADIUS mode is chosen), though the Operating System
must also support 802.1x protocol. For Microsoft’s OS family, only
Windows XP has incorporated this by default. Other operating
systems must install a third-party client software such as Funk
ODySSey.
WPA-Preshared key: There are two encryption options for WPA
Pre-Shared Key; TKIP and AES.
•TKIP stands for Temporal Key Integrity Protocol. TKIP uses a
stronger encryption method and incorporates Message Integrity
Code (MIC) to provide protection against hackers.
•AES stands for Advanced Encryption System, which uses a
symmetric 128-Bit block data encryption.
To use WPA Pre-Shared Key, enter a password in the WPA Shared
Key field between 8 and 63 characters long. You may also enter a
Group Key Renewal Interval time between 0 and 99,999 seconds.
WPA RADIUS: WPA RADIUS uses an external RADIUS server to
perform user authentication. To use WPA RADIUS, enter the IP
address of the RADIUS server, the RADIUS Port (default is 1812)
and the shared secret from the RADIUS server.
Click Apply to save your settings.

VPN Pass-Through: Virtual Private Networking (VPN) is typically
used for work-related networking. For VPN tunnels, the Wireless
router supports IPSec Pass-Through, L2TP Pass-Through, and
PPTP Pass-Through.
•IPSec - Internet Protocol Security (IPSec) is a suite of protocols
used to implement secure exchange of packets at the IP layer.
To allow IPSec tunnels to pass through the Wireless router,
IPSec Pass-Through is enabled by default. To disable IPSec
Pass-Through, uncheck the box next to IPSec.
•L2TP - Layer 2 Tunneling Protocol is a protocol used to tunnel
Point-to-Point Protocol (PPP) over the Internet. To allow L2TP
tunnels to pass through the Wireless router, L2TP Pass-
Through is enabled by default. To disable L2TP Pass-Through,
uncheck the box next to L2TP.
ViewSonic Wireless Router 22
•PPTP - Point-to-Point Tunneling Protocol is the method used to
enable VPN sessions to a Windows NT 4.0 or 2000 server. To
allow PPTP tunnels to pass through the Wireless router, PPTP
Pass-Through is enabled by default. To disable PPTP Pass-
Through, uncheck the box next to PPTP.

four different filters.
•Proxy - Use of WAN proxy servers may compromise network
security. Denying Proxy will disable access to any WAN proxy
servers. To enable proxy filtering, click the box next to Proxy.
•Java - Java is a programming language for websites. If you
deny Java, you run the risk of not having access to Internet
sites created using this programming language. To enable Java
filtering, click the box next to Java.
•ActiveX - ActiveX is a programming language for websites. If
you deny ActiveX, you run the risk of not having access to
Internet sites created using this programming language. To
enable ActiveX filtering, click the box next to ActiveX.
•Cookies - A cookie is data stored on your PC and used by
Internet sites when you interact with them. To enable cookie
filtering, click the box next to Cookies.
DMZ: The DMZ hosting feature allows one local user to be
exposed to the Internet for use of a special-purpose service such
as Internet gaming or videoconferencing. DMZ hosting forwards all
the ports at the same time to one PC. The Port Forwarding feature
is more secure because it only opens the ports you want to have
ViewSonic Wireless Router 23
opened, while DMZ hosting opens all the ports of one computer,
exposing the computer so the Internet can see it.
Any PC whose port is being forwarded must have its DHCP client
function disabled and should have a new static IP address
assigned to it because its IP address may change when using the
DHCP function.
1To expose one PC, select Enable.
2Enter the computer's IP address in the DMZ Host IP
Address field.
3Click the Apply button.
Block WAN ICMP Request: By enabling the Block WAN Request

1000. A beacon is a packet broadcast by the wireless router to
synchronize the wireless network. The default value is 100.
RTS Threshold: This value should remain at its default setting of
2346. Should you encounter inconsistent data flow, only minor
modifications are recommended. If a network packet is smaller
than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The wireless router sends Request to Send (RTS)
frames to a particular receiving station and negotiates the sending
of a data frame. After receiving an RTS, the wireless station
responds with a Clear to Send (CTS) frame to acknowledge the
right to begin transmission.
Fragmentation Threshold: This value specifies the maximum size
for a packet before data is fragmented into multiple packets. It
should remain at its default setting of 2346. If you experience a
high packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result
in poor network performance. Only minor modifications of this
value are recommended.
AP Mode or Wireless Bridge Mode: wireless router can operate
in two modes. When the AP Mode is selected, the device operates
ViewSonic Wireless Router 38
as a normal Access Point. Proving every wireless client station a
join network point. The Wireless Bridge Mode will be able to join
different wireless router wirelessly by input the destination MAC
Address.

Wireless Security & Glossary
10BaseT. An IEEE standard (802.3) for operating 10 Mbps
Ethernet networks (LANs) with twisted pair cabling and a wiring
hub.
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;
802.11a is a different standard for wireless LANs, and pertains to
systems operating in the 5 GHz frequency range with a bandwidth
of 54 Mbps. Another standard, 802.11g, is for WLANS operating in
the 2.4 GHz frequency but with a bandwidth of 54 Mbps.
ViewSonic Wireless Router 53
802.11a. An IEEE specification for wireless networking that
operates in the 5 GHz frequency range (5.725 GHz to 5.850 GHz)
with a maximum 54 Mbps data transfer rate. The 5 GHz frequency
band is not as crowded as the 2.4 GHz frequency, because the
802.11a specification offers more radio channels than the 802.11b.
These additional channels can help avoid radio and microwave
interference.
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
ViewSonic Wireless Router 54
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 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.
Ad-Hoc mode. A client setting that provides independent peer-to-
peer connectivity in a wireless LAN. An alternative set-up is one
where PCs communicate with each other through an AP.
Applet. An application or utility program that is designed to do a
very specific and limited task.
Backbone. The central part of a large network that links two or
more subnetworks and is the primary path for data transmission for
a large business or corporation. A network can have a wired
backbone or a wireless backbone.
ViewSonic Wireless Router 55
Bandwidth. The amount of transmission capacity that is available
on a network at any point in time. Available bandwidth depends on
several variables such as the rate of data transmission speed
between networked devices, network overhead, number of users,
and the type of device used to connect PCs to a network. It is
similar to a pipeline in that capacity is determined by size: the wider
the pipe, the more water can flow through it; the more bandwidth a
network provides, the more data can flow through it. Standard
802.11b provides a bandwidth of 11 Mbps; 802.11a and 802.11g
provide a bandwidth of 54 Mbps.
Bits per second (bps). A measure of data transmission speed
over communication lines based on the number of bits that can be
sent or received per second. Bits per second—bps—is often
confused with bytes per second—Bps. While "bits" is a measure of
transmission speed, "bytes" is a measure of storage capability. 8
bits make a byte, so if a wireless network is operating at a
bandwidth of 11 megabits per second (11 Mbps or 11 Mbits/sec), it
is sending data at 1.375 megabytes per second (1.375 MBps).
Bluetooth wireless technology. A technology specification for
linking portable computers, personal digital assistants (PDAs) and
mobile phones for short-range transmission of voice and data
across a global radio frequency band without the need for cables or
wires. Bluetooth is a frequency-hopping technology in the 2.4 GHz
frequency spectrum, with a range of 30 feet.
Bridge. A product that connects a local area network (LAN) to
another local area network that uses the same protocol (for
ViewSonic Wireless Router 56
example, wireless, Ethernet or token ring). Wireless bridges are
commonly used to link buildings in campuses.
Broadband. A comparatively fast Internet connection. Services
such as ISDN, cable modem, DSL and satellite are all considered
broadband as compared to dial-up Internet access. There is no
official speed definition of broadband but services of 100Kbps and
above are commonly thought of as broadband.
Bus adapter. A special adapter card that installs in a PC's PCI or
ISA slot and enables the use of PC Card radios in desktop
computers. Some companies offer one-piece PCI or ISA Card
radios that install directly into an open PC or ISA slot.
Cable modem. A kind of converter used to connect a computer to
a cable TV service that provides Internet access. Most cable
modems have an Ethernet out-cable that then attaches to the
user's Wi-Fi gateway.
Client. Any computer connected to a network that requests
services (files, print capability) from another member of the
network.
Client devices. Clients are end users. Wi-Fi client devices include
PC Cards that slide into laptop computers, mini-PCI modules
embedded in laptop computers and mobile computing devices, as
well as USB radios and PCI/ISA bus Wi-Fi radios. Client devices
usually communicate with hub devices like access points and
gateways.
ViewSonic Wireless Router 57
Collision avoidance. A network node characteristic for proactively
detecting that it can transmit a signal without risking a collision.
Crossover cable. A special cable used for networking two
computers without the use of a hub. Crossover cables may also be
required for connecting a cable or DSL modem to a wireless
gateway or access point. Instead of the signals transferring in
parallel paths from one set of plugs to another, the signals
"crossover." If an eight-wire cable was being used, for instance, the
signal would start on pin one at one end of the cable and end up on
pin eight at the other end. They "cross-over" from one side to the
other.
ViewSonic Wireless Router 58
CSMA/CA (Carrier Sense Multiple Access with Collision
Avoidance). The principle medium access method employed by
IEEE 802.11 WLANs. It is a "listen before talk": method of
minimizing (but not eliminating) collisions caused by simultaneous
transmission by multiple radios. IEEE 802.11 states collision
avoidance method rather than collision detection must be used,
because the standard employs half duplex radios—radios capable
of transmission or reception—but not both simultaneously. Unlike
conventional wired Ethernet nodes, a WLAN station cannot detect
a collision while transmitting. If a collision occurs, the transmitting
station will not receive an ACKnowledge packet from the intended
receive station. For this reason, ACK packets have a higher priority
than all other network traffic. After completion of a data
transmission, the receive station will begin transmission of the ACK
packet before any other node can begin transmitting a new data
packet. All other stations must wait a longer pseudo randomized
period of time before transmitting. If an ACK packet is not received,
the transmitting station will wait for a subsequent opportunity to
retry transmission.
CSMA/CD (Carrier Sense Multiple Access/Collision Detection). A
method of managing traffic and reducing noise on an Ethernet
network. A network device transmits data after detecting that a
channel is available. However, if two devices transmit data
simultaneously, the sending devices detect a collision and
retransmit after a random time delay.
DC power module. Modules that convert AC power to DC.
Depending on manufacturer and product, these modules can range
ViewSonic Wireless Router 59
from typical "wall wart" transformers that plug into a wall socket and
provide DC power via a tiny plug to larger, enterprise-level Power
Over Ethernet systems that inject DC power into the Ethernet
cables connecting access points.
DHCP (Dynamic Host Configuration Protocol). A utility that enables
a server to dynamically assign IP addresses from a predefined list
and limit their time of use so that they can be reassigned. Without
DHCP, an IT Manager would have to manually enter in all the IP
addresses of all the computers on the network. When DHCP is
used, whenever a computer logs onto the network, it automatically
gets an IP address assigned to it.
Dial-up. A communication connection via the standard telephone
network, or Plain Old Telephone Service (POTS).
Diversity antenna - A type of antenna system that uses two
antennas to maximize reception and transmission quality and
reduce interference.
DNS (Domain Name System, or Service, or Server). A program
that translates URLs to IP addresses by accessing a database
maintained on a collection of Internet servers. The program works
behind the scenes to facilitate surfing the Web with alpha versus
numeric addresses. A DNS server converts a name like
mywebsite.com to a series of numbers like 107.22.55.26. Every
website has its own specific IP address on the Internet.
ViewSonic Wireless Router 60
DSL (Digital Subscriber Lines). Various technology protocols for
high-speed data, voice and video transmission over ordinary
twisted-pair copper POTS (Plain Old Telephone Service) telephone
wires.
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.
ESSID (Extended Service Set ID). 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.
Ethernet. International standard networking technology for wired
implementations. Basic 10BaseT networks offer a bandwidth of
about 10 Mbps. Fast Ethernet (100 Mbps) and Gigabit Ethernet
(1000 Mbps) are becoming popular.
Firewall. A system that secures a network and prevents access by
unauthorized users. Firewalls can be software, hardware or a
combination of both. Firewalls can prevent unrestricted access into
a network, as well as restrict data from flowing out of a network.
ViewSonic Wireless Router 61
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.
HotSpot. A place where you can access Wi-Fi service. This can be
for free or for a fee. HotSpots can be inside a coffeeshop, airport
lounge, train station, convention center, hotel or any other public
meeting area. Corporations and campuses are also implementing
HotSpots to provide wireless Internet access to their visitors and
guests. In some parts of the world, HotSpots are known as
CoolSpots.
Hub. A multiport device used to connect PCs to a network via
Ethernet cabling or via WiFi. Wired hubs can have numerous ports
and can transmit data at speeds ranging from 10 Mbps to
multigigabyte speeds per second. A hub transmits packets it
receives to all the connected ports. A small wired hub may only
connect four computers; a large hub can connect 48 or more.
Wireless hubs can connect hundreds.
HZ (Hertz). The international unit for measuring frequency,
equivalent to the older unit of cycles per second. One megahertz
(MHz) is one million hertz. One gigahertz (GHz) is one billion hertz.
The standard US electrical power frequency is 60 Hz, the AM
broadcast radio frequency band is 535—1605 kHz, the FM
broadcast radio frequency band is 88—108 MHz, and wireless
802.11b LANs operate at 2.4 GHz.
ViewSonic Wireless Router 62
IEEE (Institute of Electrical and Electronics Engineers), New York,
www.ieee.org. A membership organization that includes engineers,
scientists and students in electronics and allied fields. It has more
than 300,000 members and is involved with setting standards for
computers and communications.
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.
Infrastructure mode. A client setting providing connectivity to an
AP. As compared to Ad-Hoc mode, whereby PCs communicate
directly with each other, clients set in Infrastructure Mode all pass
data through a central AP. The AP not only mediates wireless
network traffic in the immediate neighborhood, but also provides
communication with the wired network. See Ad-Hoc and AP.
Internet appliance. A computer that is intended primarily for
Internet access, is simple to set up and usually does not support
installation of third-party software. These computers generally offer
customized web browsing, touch-screen navigation, e-mail
services, entertainment and personal information management
ViewSonic Wireless Router 63
applications. An Internet appliance can be Wi-Fi enabled or it can
be connected via a cable to the local network.
IP (telephony). Technology that supports voice, data and video
transmission via IP-based LANs, WANs, and the Internet. This
includes VoIP (Voice over IP).
IP address. A 32-bit number that identifies each sender or receiver
of information that is sent across the Internet. An IP address has
two parts: an identifier of a particular network on the Internet and
an identifier of the particular device (which can be a server or a
workstation) within that network.
IPX-SPX (Internetwork Packet Exchange-Sequenced Packet
Exchange). IPX is a networking protocol used by the Novell
NetWare operating systems. Like UDP/IP, IPX is a datagram
protocol used for connectionless communications. Higher-level
protocols, such as SPX and NCP, are used for additional error
recovery services. SPX is a transport layer protocol (layer 4 of the
OSI Model) used in Novell Netware networks. The SPX layer sits
on top of the IPX layer (layer 3) and provides connection-oriented
services between two nodes on the network. SPX is used primarily
by client/server applications. Whereas the IPX protocol is similar to
IP, SPX is similar to TCP. Together, therefore, IPX-SPX provides
connection services similar to TCP/IP.
ISA (Industry Standard Architecture). A type of internal computer
bus that allows the addition of card-based components like
ViewSonic Wireless Router 64
modems and network adapters. ISA has been replaced by PCI and
is not very common anymore.
ISO Network Model (International Standards Organization). A
network model developed by the ISO that consists of seven
different levels, or layers. By standardizing these layers, and the
interfaces in between, different portions of a given protocol can be
modified or changed as technologies advance or systems
requirements are altered. The seven layers are:
•Physical
•Data Link
•Network
•Transport
•Session
•Presentation
•Application
The IEEE 802.11 Standard encompasses the physical layer (PHY)
and the lower portion of the data link layer. The lower portion of the
data link layer is often referred to as the Medium Access Controller
(MAC) sublayer.
ISS (Internet Security Services). A special software application that
allows all PCs on a network access to the Internet simultaneously
through a single connection and Internet Service Provider (ISP)
account.
LAN (Local Area Network). A system of connecting PCs and other
devices within the same physical proximity for sharing resources
ViewSonic Wireless Router 65
such as an Internet connections, printers, files and drives. When
Wi-Fi is used to connect the devices, the system is known as a
wireless LAN or WLAN.
MAC (Medium Access Controller). 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.
Mapping. Assigning a PC to a shared drive or printer port on a
network.
NAT (Network Address Translation). A network capability that
enables a houseful of computers to dynamically share a single
incoming IP address from a dial-up, cable or xDSL connection.
NAT takes the single incoming IP address and creates new IP
address for each client computer on the network. NAT provides a
type of firewall by hiding internal IP addresses.
Network name. Identifies the wireless network for all the shared
components. During the installation process for most wireless
networks, you need to enter the network name or SSID. Different
network names are used when setting up your individual computer,
wired network or workgroup.
NIC (Network Interface Card). An expansion board you insert into a
computer so the computer can be connected to a network. A NIC is
ViewSonic Wireless Router 66
a type of PC adapter card that either works without wires (Wi-Fi) or
attaches to a network cable to provide two-way communication
between the computer and network devices such as a hub or
switch. Most office wired NICs operate at 10 Mbps (Ethernet), 100
Mbps (Fast Ethernet) or 10/100 Mbps dual speed. High-speed
Gigabit and 10 Gigabit NIC cards are also available. See PC Card.
PC Card. A removable, credit-card-sized memory or I/O device
that fits into a Type 2 PCMCIA standard slot, PC Cards are used
primarily in PCs, portable computers, PDAs and laptops. PC Card
peripherals include Wi-Fi cards, memory cards, modems, NICs,
hard drives, etc.
PCI (Peripheral Component Interconnect). A high-performance I/O
computer bus used internally on most computers. Other bus types
include ISA and AGP. PCIs and other computer buses enable the
addition of internal cards that provide services and features not
supported by the motherboard or other connectors.
PCMCIA (Personal Computer Memory Card International
Association). Expansion cards now referred to as “PC Cards” were
originally called “PCMCIA Cards” because they met the standards
created by the PCMCIA.
ViewSonic Wireless Router 67
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 various signals can collide with each other, reducing
overall performance.
PHY (Physical Layer). The lowest layer within the OSI Network
Model. It deals primarily with transmission of the raw bit stream
over the PHYsical transport medium. In the case of wireless LANs,
the transport medium is free space. The PHY defines parameters
such as data rates, modulation method, signaling parameters,
transmitter/receiver synchronization, etc. Within an actual radio
implementation, the PHY corresponds to the radio front end and
baseband signal processing sections.
Proxy server. Used in larger companies and organizations to
improve network operations and security, a proxy server is able to
prevent direct communication between two or more networks. The
proxy server forwards allowable data requests to remote servers
and/or responds to data requests directly from stored remote
server data.
Range. How far will your wireless network stretch? Most Wi-Fi
systems will provide a range of a hundred feet or more. Depending
on the environment and the type of antenna used, Wi-Fi signals
can have a range of up to mile.
ViewSonic Wireless Router 68
Residential gateway. A wireless device that connects multiple
PCs, peripherals and the Internet on a home network. Most Wi-Fi
residential gateways provide DHCP and NAT as well.
RJ-45. Standard connectors used in Ethernet networks. Even
though they look very similar to standard RJ-11 telephone
connectors, RJ-45 connectors can have up to eight wires, whereas
telephone connectors have only four.
Roaming. Moving seamlessly from one AP coverage area to
another with no loss in connectivity.
Router. A device that forwards data packets from one local area
network (LAN) or wide area network (WAN) to another. Based on
routing tables and routing protocols, routers can read the network
address in each transmitted frame and make a decision on how to
send it via the most efficient route based on traffic load, line costs,
speed, bad connections, etc.
Server. A computer that provides its resources to other computers
and devices on a network. These include print servers, Internet
servers and data servers. A server can also be combined with a
hub or router.
SSID (Service Set Identifier). 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
ViewSonic Wireless Router 69
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.
SSL (Secure Sockets Layer). Commonly used encryption scheme
used by many online retail and banking sites to protect the financial
integrity of transactions. When an SSL session begins, the server
sends its public key to the browser. The browser then sends a
randomly generated secret key back to the server in order to have
a secret key exchange for that session.
Subnetwork or Subnet. Found in larger networks, these smaller
networks are used to simplify addressing between numerous
computers. Subnets connect to the central network through a
router, hub or gateway. Each individual wireless LAN will probably
use the same subnet for all the local computers it talks to.
Switch. A type of hub that efficiently controls the way multiple
devices use the same network so that each can operate at optimal
performance. A switch acts as a networks traffic cop: rather than
transmitting all the packets it receives to all ports as a hub does, a
switch transmits packets to only the receiving port.
TCP (Transmission Control Protocol). A protocol used along with
the Internet Protocol (IP) to send data in the form of individual units
(called packets) between computers over the Internet. While IP
ViewSonic Wireless Router 70
takes care of handling the actual delivery of the data, TCP takes
care of keeping track of the packets that a message is divided into
for efficient routing through the Internet. For example, when a web
page is downloaded from a web server, the TCP program layer in
that server divides the file into packets, numbers the packets, and
then forwards them individually to the IP program layer. Although
each packet has the same destination IP address, it may get routed
differently through the network. At the other end, TCP reassembles
the individual packets and waits until they have all arrived to
forward them as a single file.
TCP/IP (Transmission Control Protocol/Internet Protocol).The
underlying technology behind the Internet and communications
between computers in a network. The first part, TCP, is the
transport part, which matches the size of the messages on either
end and guarantees that the correct message has been received.
The IP part is the user's computer address on a network. Every
computer in a TCP/IP network has its own IP address that is either
dynamically assigned at startup or permanently assigned. All TCP/
IP messages contain the address of the destination network as well
as the address of the destination station. This enables TCP/IP
messages to be transmitted to multiple networks (subnets) within
an organization or worldwide.
UPnP. A networking architecture that provides compatibility among
networking equipment, software and peripherals of the 400+
vendors that are part of the Universal Plug and Play Forum. UPnP
works with wired or wireless networks and can be supported on
ViewSonic Wireless Router 71
any operating system. UPnP boasts device-driver independence
and zero-configuration networking.
USB (Universal Serial Bus). A high-speed bidirectional serial
connection between a PC and a peripheral that transmits data at
the rate of 12 megabits per second. The new USB 2.0 specification
provides a data rate of up to 480 Mbps, compared to standard USB
at only 12 Mbps. 1394, FireWire and iLink all provide a bandwidth
of up to 400 Mbps.
VoIP (VoiceOver Internet Protocol). Voice transmission using
Internet Protocol to create digital packets distributed over the
Internet. VoIP can be less expensive than voice transmission using
standard analog packets over POTS (Plain Old Telephone
Service).
VPN (Virtual Private Network). A type of technology designed to
increase the security of information transferred over the Internet.
VPN can work with either wired or wireless networks, as well as
with dial-up connections over POTS. VPN creates a private
encrypted tunnel from the end user's computer, through the local
wireless network, through the Internet, all the way to the corporate
servers and database.
WAN (Wireless Area Network). A communication system of
connecting PCs and other computing devices across a large local,
regional, national or international geographic area. Also used to
distinguish between phone-based data networks and Wi-Fi. Phone
ViewSonic Wireless Router 72
networks are considered WANs and Wi-Fi networks are considered
Wireless Local Area Networks (WLANs).
WEP (Wired Equivalent Privacy). 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 (Wireless Fidelity). An inter-operability certification for
wireless local area network (LAN) products based on the Institute
of Electrical and Electronics Engineers (IEEE) 802.11 standard.
WLAN (Wireless Local Area Network). Also referred to as LAN. A
type of local-area network that uses high-frequency radio waves
rather than wires to communicate between nodes.
WPA-Enterprise (Wi-Fi Protected Access™ – Enterprise). It is Wi-
Fi’s encryption method that protects unauthorized network access
by verifying network users through a server.
WPA-Personal (Wi-Fi Protected Access™ – Personal). It is Wi-Fi’s
encryption method that protects unauthorized network access by
using a set-up password.

Troubleshooting
Basic Functions
1If you are using a cable or DSL modem and are
experiencing problems connecting to the Internet, do
the following:
•Power off your cable or DSL modem, PC, and the router.
•Power on your modem and wait a few minutes until the
modem has established a connection with your ISP.
•Power on the router.
•Power on your PC and attempt to connect to the Internet.
For most users, the router's default values should be
satisfactory. Some users may need to enter additional
information in order to connect to the Internet through
their ISP or broadband (cable or DSL) carrier. For
example, some cable providers require a specific MAC
address for connection to the Internet. To learn more
about this, click the Advanced tab and then the MAC
Address Clone tab.
