The initial Argon 4x1 Customer Evaluation Board only supports
the green Power LED (D1705 – TOP). This table is provided as
an example of the LEDs that your product may support. You
must edit this table to reflect your own LED configuration. [CT25]
If the LEDs illuminate as expected, test your Internet connection
from a LAN computer (and from the USB computer, if
applicable). To do this, open your web browser, and type the
URL of any external website (such as http://www.yahoo.com).
The LED labeled LINK/Act DSL should be blinking rapidly and
may appear solid as the device connects to the site.
If the LEDs do not illuminate as expected, you may need to
configure your Internet access settings using the information
provided by your ISP. For details, see Internet Access on page
66. If the LEDs still do not illuminate as expected, or the web
page is not displayed, see Troubleshooting Suggestions on
page 102, or contact your ISP for assistance.
Default device settings
In addition to handling the DSL connection to your ISP, the DSL
Modem can provide a variety of services to your network. The
device is preconfigured with default settings for use with a
typical home or small office network.
The table below lists some of the most important default settings;
these and other features are described fully in the subsequent
chapters. If you are familiar with network configuration, review
these settings to verify that they meet the needs of your network.
Follow the instructions to change them if necessary. If you are
unfamiliar with these settings, try using the device without
modification, or contact your ISP for assistance.
Before you modify any settings, we strongly recommend that
you contact your ISP prior to changing the default configuration.

Configure Wireless Network Security
The following page allows you to configure wireless security:
Figure 36: Wireless Network: Security page
You can protect your wireless data from potential
eavesdroppers by encrypting wireless data transmissions. An
eavesdropper might set up a compatible wireless adapter within
range of your device and attempt to access your network. Data
encryption is the translation of data into a form that cannot be
easily understood by unauthorized users.
There are two methods of wireless security to choose from:
• Wired Equivalent Privacy (WEP); data is encrypted into
blocks of either 64 bits length or 128 bits length. The
encrypted data can only be sent and received by users with
access to a private network key. Each PC on your wireless
network must be manually configured with the same key as
your device in order to allow wireless encrypted data
transmissions. Eavesdroppers cannot access your network
if they do not know your private key. WEP is considered to
be a low security option.

11 Advanced Security
Your device has built in advanced Security features that protect
your network by blocking unwanted traffic from the Internet.
If you simply want to connect from your local network to the
Internet, you do not need to make any changes to the default
Security configuration. You only need to edit the configuration if
you wish to do one or both of the following:
• allow Internet users to browse the user pages on your local
network (for example, by providing an FTP or HTTP server)
• play certain games which require accessibility from the
Internet
This chapter describes how to configure Security to suit the
needs of your network.
By default, the IP addresses of your LAN PCs are hidden from
the Internet. All data sent from your LAN PCs to a PC on the
Internet appears to come from the IP address of your device.
(To display your device’s IP address, see Current Status on
page 25.) In this way, details about your LAN PCs remain
private. This security feature is called Network Address
Translation (NAT).
Configuring NAT Security
Certain network games, chat or file sharing software do not
work with your default NAT setting. Your device knows the port,
protocol and trigger information needed to allow access to the
common applications listed below, but by default, access to
them is disabled.

12 Internet Access
This chapter describes how to configure the way that your
device connects to the Internet. Your ISP determines what type
of Internet access you should use and provides you with any
information that you need in order to configure the Internet
access to your device.
Your device needs the following address information in order to
access the Internet:
IP address and
subnet mask: The IP address and subnet mask
assigned to your WAN interface.
Default gateway: The gateway address that identifies the
ISP server through which your Internet
connection will be routed.
DNS servers: The Dynamic Name System (DNS)
servers used by your ISP to dynamically
assign addresses to each of the
computers attached to your LAN.
In most cases, you will not need to configure your device with
these addresses because your ISP is likely to use an Internet
access type which automatically assigns addresses to your
device. For more information, see Types of Internet Access on
page 66.
Types of Internet Access
The types of Internet access available are as follows:
• Automatic Internet access – your device scans the Internet
via the DSL connection in order to find a link to the ISP’s
Internet service. The IP addresses required to access your
ISP’s Internet service are automatically configured.
• PPP Internet access – your device uses a Point to Point
Protocol (PPP) to carry data between your ISP and your
computer. To use PPP Internet access, you must enter a
PPP login username and password the first time to log
on. The IP addresses required to access your ISP’s
Internet service are automatically configured.
Your device supports two types of PPP – PPPoE (over
Ethernet) and PPPoA (over ATM).
• DHCP – your ISP uses a protocol called Dynamic Host
Configuration Protocol (DHCP) to assign addresses and
manage your device. The device is automatically assigned
the IP addresses that it needs to access the Internet.
• Manual – you manually assign the addresses that your
device needs in order to access the Internet. Your ISP
should provide you with the necessary addresses.

password so they can check that you are a legitimate,
registered Internet service user. Your device stores these
authentication details, so you will not have to enter this
username and password every time you login.
Your ISP may also tell you to set unique path and circuit
numbers (called VPI and VCI) in order to connect your device to
the ISP’s Internet service. In most cases, your device will use
default settings, so you may not need to enter these values.
Note
Your ISP will provide you with the login details and VPI/VCI
values necessary to set up a PPP login account.
If your ISP wants you to connect to the Internet using PPP,
follow the instructions below.
1. From the left-hand Setup menu, click on Internet Access.
The following page is displayed:

If you have configured PPPoE Internet access, notice that an
extra configuration option called MAC Spoofing appears on this
page:
Figure 74: Internet Access: PPPoE page
MAC spoofing allows you to set the Media Access Control
(MAC) address of your device. See Enabling MAC spoofing on
page 10 for more details.
Enabling MAC spoofing
Note
You should only enable MAC spoofing if your ISP has requested
that you do so. In most cases, you will not need to do this.
Your ISP identifies your modem by its unique hardware number
or Media Access Control (MAC) address. If you are using
PPPoE Internet access, your ISP may want you to spoof the
identity of a different device. You can spoof the MAC address of
another device by replacing your device’s existing MAC address
with another device’s address. Your ISP will provide you with
the replacement MAC address.

Assigning static Internet information to your PCs
If you are like most users, you will not need to assign static
Internet information to your LAN PCs. Your ISP automatically
assigns this information.
In some cases however, you may want to assign Internet
information to some or all of your PCs directly (often called
“statically”), rather than allowing the 錯誤! 尚未定義樣式。 to
assign it. This option may be desirable (but not required) if:
• You have obtained one or more public IP addresses that you
want to always associate with specific computers (for
example, if you are using a computer as a public web server).
• You maintain different subnets on your LAN (subnets are
described in Appendix B).
Before you begin, be sure to have the following information on
hand, or contact your ISP if you do not know it:
• The IP address and subnet mask to be assigned to each PC
to which you will be assigning static IP information.
• The IP address of the default gateway for your LAN. In most
cases, this is the address assigned to the LAN port on the 錯
誤! 尚未定義樣式。. By default, the LAN port is assigned
this IP address: 192.168.1.1. (You can change this number,
or another number can be assigned by your ISP. See
Addressing on page 42 for more information.)
• The IP address of your ISP’s Domain Name System (DNS)
server.
On each PC to which you want to assign static information, follow
the instructions on pages 82 through 87 relating only to checking
for and/or installing the IP protocol. Once it is installed, continue
to follow the instructions for displaying each of the Internet
Protocol (TCP/IP) properties. Instead of enabling dynamic
assignment of the IP addresses for the computer, DNS server
and default gateway, click the radio buttons that enable you to
enter the information manually.
Note
Your PCs must have IP addresses that place them in the same
subnet as the
錯誤
!
尚未定義樣式。
’s LAN port. If you manually
assign IP information to all your LAN PCs, you can follow the
instructions in Addressing on page 42 to change the LAN port IP
address accordingly.

• If you want to assign a static IP address to the PC, follow the
instructions on page 88 and use the following information:
• In the Network and Dial-up Connections window, be sure
to select the icon that corresponds to your new USB
connection (not the one that corresponds to your

Configuring Wireless PCs
You need to configure the operating system installed on your
Wireless PCs using the same procedure described for Configuring
Ethernet PCs on page 82.
Positioning the wireless PCs
The wireless network cards used determine the maximum distance
between your wireless PCs and your device. Guidelines on
positioning the hardware components of your wireless network
should be provided by your network card provider.
Wireless PC cards and drivers
Each PC on your wireless LAN must be fitted with a wireless
access card. You must also install the corresponding driver files for
your particular wireless card on your PC. You should receive driver
files and instructions on how to install them together with your
wireless card.
Configuring PC access to your Wireless device
Before you start configuring your Wireless PC, you must ensure that
you have:
• A Wireless access card for each of the PCs
• Corresponding wireless access card driver software files
The configuration steps below will vary depending on both the
operating system and wireless card installed on the PC. These
steps provide a basic outline, however you should refer to the
documentation provided with your wireless access card for specific
instructions.
To configure your Wireless PCs:
1. Install the wireless access card.
2. Install the wireless driver software files.
3. Configure the following wireless parameters on each of the
wireless PCs:
a. Set the adapter to use infrastructure mode. This
configures the PCs to access each other and the
Internet via the device.
b. Configure the SSID and channel to match the SSID
and channel previously configured on the device (see
Set the Wireless Network Name on page 46 and
Select a Channel on page 47).
c. If you are using Wired Equivalent Privacy (WEP)
security, configure the same network key that was
previously configured on the device (see Configuring
64bit or 128bit encryption on page 49). If you are using
Wi-Fi Protected Access (WPA) security, configure the

IP Addresses
Note
This section refers only to IP addresses for IPv4 (version 4 of the
Internet Protocol). IPv6 addresses are not covered.
This section assumes basic knowledge of binary numbers, bits,
and bytes.
IP addresses, the Internet's version of telephone numbers, are used
to identify individual nodes (computers or devices) on the Internet.
Every IP address contains four numbers, each from 0 to 255 and
separated by dots (periods), e.g. 20.56.0.211. These numbers are
called, from left to right, field1, field2, field3, and field4.
This style of writing IP addresses as decimal numbers separated by
dots is called dotted decimal notation. The IP address 20.56.0.211
is read "twenty dot fifty-six dot zero dot two-eleven."
Structure of an IP address
IP addresses have a hierarchical design similar to that of telephone
numbers. For example, a 7-digit telephone number starts with a 3-
digit prefix that identifies a group of thousands of telephone lines,
and ends with four digits that identify one specific line in that group.
Similarly, IP addresses contain two kinds of information:
• Network ID
Identifies a particular network within the Internet or intranet
• Host ID
Identifies a particular computer or device on the network
The first part of every IP address contains the network ID, and the
rest of the address contains the host ID. The length of the network
ID depends on the network's class (see following section). The table
below shows the structure of an IP address.
Field1 Field2 Field3 Field4
Class A Network ID Host ID
Class B Network ID Host ID
Class C Network ID Host ID
Here are some examples of valid IP addresses:
Class A: 10.30.6.125 (network = 10, host = 30.6.125)
Class B: 129.88.16.49 (network = 129.88, host = 16.49)
Class C: 192.60.201.11 (network = 192.60.201, host = 11)

Network classes
The three commonly used network classes are A, B, and C. (There
is also a class D but it has a special use beyond the scope of this
discussion.) These classes have different uses and characteristics.
Class A networks are the Internet's largest networks, each with
room for over 16 million hosts. Up to 126 of these huge networks
can exist, for a total of over 2 billion hosts. Because of their huge
size, these networks are used for WANs and by organizations at the
infrastructure level of the Internet, such as your ISP.
Class B networks are smaller but still quite large, each able to hold
over 65,000 hosts. There can be up to 16,384 class B networks in
existence. A class B network might be appropriate for a large
organization such as a business or government agency.
Class C networks are the smallest, only able to hold 254 hosts at
most, but the total possible number of class C networks exceeds 2
million (2,097,152 to be exact). LANs connected to the Internet are
usually class C networks.
Some important notes regarding IP addresses:
• The class can be determined easily from field1:
field1 = 1-126: Class A
field1 = 128-191: Class B
field1 = 192-223: Class C
(field1 values not shown are reserved for special uses)
• A host ID can have any value except all fields set to 0 or all
fields set to 255, as those values are reserved for special uses.
Subnet masks
Definition
mask
A mask looks like a regular IP address, but contains a pattern of
bits that tells what parts of an IP address are the network ID and
what parts are the host ID: bits set to 1 mean "this bit is part of the
network ID" and bits set to 0 mean "this bit is part of the host ID."
Subnet masks are used to define subnets (what you get after
dividing a network into smaller pieces). A subnet's network ID is
created by "borrowing" one or more bits from the host ID portion of
the address. The subnet mask identifies these host ID bits.
For example, consider a class C network 192.168.1. To split this
into two subnets, you would use the subnet mask:
255.255.255.128
It's easier to see what's happening if we write this in binary:
11111111. 11111111. 11111111.10000000
As with any class C address, all of the bits in field1 through field3
are part of the network ID, but note how the mask specifies that the
first bit in field4 is also included. Since this extra bit has only two
錯誤

User’s Guide IP Addresses, Network Masks, and Subnets
101
values (0 and 1), this means there are two subnets. Each subnet
uses the remaining 7 bits in field4 for its host IDs, which range from
1 to 126 hosts (instead of the usual 0 to 255 for a class C address).
Similarly, to split a class C network into four subnets, the mask is:
255.255.255.192 or 11111111. 11111111. 11111111.11000000
The two extra bits in field4 can have four values (00, 01, 10, 11), so
there are four subnets. Each subnet uses the remaining six bits in
field4 for its host IDs, ranging from 1 to 62.
Note
Sometimes a subnet mask does not specify any additional
network ID bits, and thus no subnets. Such a mask is called a
default subnet mask. These masks are:
Class A: 255.0.0.0
Class B: 255.255.0.0
Class C: 255.255.255.0
These are called default because they are used when a network is
initially configured, at which time it has no subnets.

Diagnosing Problem using IP Utilities
ping
Ping is a command you can use to check whether your PC can
recognize other computers on your network and the Internet. A ping
command sends a message to the computer you specify. If the
computer receives the message, it sends messages in reply. To
use it, you must know the IP address of the computer with which
you are trying to communicate.
On Windows-based computers, you can execute a ping command
from the Start menu. Click the Start button, and then click Run. In
the Open text box, type a statement such as the following:
ping 192.168.1.1
Click OK. You can substitute any private IP address on your LAN or
a public IP address for an Internet site, if known.
If the target computer receives the message, a Command Prompt
window is displayed:
Figure 101: Using the ping Utility
If the target computer cannot be located, you will receive the
message Request timed out.
Using the ping command, you can test whether the path to the 錯誤!
尚未定義樣式。 is working (using the preconfigured default LAN IP
address 192.168.1.1) or another address you assigned.
You can also test whether access to the Internet is working by
typing an external address, such as that for www.yahoo.com
(216.115.108.243). If you do not know the IP address of a particular
Internet location, you can use the nslookup command, as explained
in the following section.
From most other IP-enabled operating systems, you can execute
the same command at a command prompt or through a system
administration utility.

DNS server (usually located with your ISP). If that name is not an
entry in your ISP’s DNS table, the request is then referred to
another higher-level server, and so on, until the entry is found. The
server then returns the associated IP address.
On Windows-based computers, you can execute the nslookup
command from the Start menu. Click the Start button, and then click
Run. In the Open text box, type the following:

that you are interested in, such as www.microsoft.com.
The window will display the associate IP address, if known, as
shown below:

There may be several addresses associated with an Internet name.
This is common for web sites that receive heavy traffic; they use
multiple, redundant servers to carry the same information.

Capability This parameter controls whether the CPE will attempt to
startup using alternate standards if the CO does not
support G.Span (High Speed (HS)).
The CPE has the ability to connect in either ADSL
Annex A or G.Span. This is provided by the
ADSL/Annex A /G.Span Auto Detect feature. The
standard used depends on the capability of the CO.
Using Auto Detect, startup at the CPE is first attempted
in Annex A. The CO is the master and the CPE is the
slave. If the result of handshake with the CO is G.Span
(HS), then the CPE will switch to G.Span. If the CO does
not support G.Span, then the resultant connection will be
ADSL Annex A.
This parameter must be set to AHS to configure the
modem for A & HS ‘two-speed’ Auto Detect. For Auto
Detect, all other parameters should be set to the Annex
A profile. If UTOPIA Level 2 framing is set (using the
UtopiaInterface parameter), ensure that the UTOPIA
address is set (using the PhysicalPort parameter) as
there is no default value. If the result of handshake with
the CO is G.Span (HS), then the CPE will switch to
G.Span and the appropriate CPE parameters will be
automatically re-configured by the DSP for G.Span
operation.

mask is used to define the network ID and the host ID. Because
IP addresses are difficult to remember, they usually have an
associated domain name that can be specified instead. See also
domain name, network mask.

office, or small building.
LED Light Emitting Diode
An electronic light-emitting device. The indicator lights on the
front of the 錯誤! 尚未定義樣式。 are LEDs.
MAC address Media Access Control address
The permanent hardware address of a device, assigned by its
manufacturer. MAC addresses are expressed as six pairs of hex
characters, with each pair separated by colons. For example;
NN:NN:NN:NN:NN:NN.

Mbps Abbreviation for Megabits per second, or one million bits per
second. Network data rates are often expressed in Mbps.
NAT Network Address Translation
A service performed by many routers that translates your
network’s publicly known IP address into a private IP address for
each computer on your LAN. Only your router and your LAN
know these addresses; the outside world sees only the public IP
address when talking to a computer on your LAN.
network A group of computers that are connected together, allowing them
to communicate with each other and share resources, such as
software, files, etc. A network can be small, such as a LAN, or
very large, such as the Internet.
network keys (also known as encryption keys) 64-bit and 128-bit encryption
keys used in WEP wireless security schemes. The keys encrypt
data over the WLAN, and only wireless PCs configured with WEP
keys that correspond to the keys configured on the device can
send/receive encrypted data.
network mask A network mask is a sequence of bits applied to an IP address to
select the network ID while ignoring the host ID. Bits set to 1
mean "select this bit" while bits set to 0 mean "ignore this bit."
For example, if the network mask 255.255.255.0 is applied to the
IP address 100.10.50.1, the network ID is 100.10.50, and the
host ID is 1. See also binary, IP address, subnet, "IP Addresses
Explained" section.
NIC Network Interface Card
An adapter card that plugs into your computer and provides the
physical interface to your network cabling, which for Ethernet
NICs is typically an RJ-45 connector. See Ethernet, RJ-45.

where it should go (destination address).
pass phrase A secret password used in WPA wireless data encryption.
Encryption is based on a WPA master key that is derived from the
pass phrase and the network name (SSID) of the device. The pass
phrase should be at least 20 characters long in order to deter a
hacker attempting to crack the pass phrase by recording a series of
frames then trying commonly used passwords offline until one
works (known as offline PSK dictionary attacks).
ping Packet Internet (or Inter-Network) Groper
A program used to verify whether the host associated with an IP
address is online. It can also be used to reveal the IP address for
a given domain name.
port A physical access point to a device such as a computer or router,
through which data flows into and out of the device.
PPP Point-to-Point Protocol
A protocol for serial data transmission that is used to carry IP
(and other protocol) data between your ISP and your computer.
The WAN interface on the 錯誤! 尚未定義樣式。 uses two forms
of PPP called PPPoA and PPPoE. See also PPPoA, PPPoE.
PPPoA Point-to-Point Protocol over ATM
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoE. You can define
only one PPPoA interface per VC.
PPPoE Point-to-Point Protocol over Ethernet
One of the two types of PPP interfaces you can define for a
Virtual Circuit (VC), the other type being PPPoA. You can define
one or more PPPoE interfaces per VC.
protocol A set of rules governing the transmission of data. In order for a
data transmission to work, both ends of the connection have to
follow the rules of the protocol.
remote In a physically separate location. For example, an employee
away on travel who logs in to the company’s intranet is a remote
user.

called a router.
SDNS Secondary Domain Name System (server)
A DNS server that can be used if the primary DSN server is not
available. See DNS.
SSID Service Set Identifier (also known as the Extended Service Set
Identifier (ESSID)) is a unique identifier that differentiates one
wireless device from another. Wireless PCs configured with the
same SSID can access that device.
subnet A subnet is a portion of a network. The subnet is distinguished
from the larger network by a subnet mask that selects some of
the computers of the network and excludes all others. The
subnet's computers remain physically connected to the rest of
the parent network, but they are treated as though they were on
a separate network. See also network mask.
subnet mask A mask that defines a subnet. See also network mask.
TCP See TCP/IP.
TCP/IP Transmission Control Protocol/Internet Protocol
The basic protocols used on the Internet. TCP is responsible for
dividing data up into packets for delivery and reassembling them
at the destination, while IP is responsible for delivering the
packets from source to destination. When TCP and IP are
bundled with higher-level applications such as HTTP, FTP,
Telnet, etc., TCP/IP refers to this whole suite of protocols.
Telnet An interactive, character-based program used to access a
remote computer. While HTTP (the web protocol) and FTP only
allow you to download files from a remote computer, Telnet
allows you to log into and use a computer from a remote location.
TFTP Trivial File Transfer Protocol
A protocol for file transfers, TFTP is easier to use than File
Transfer Protocol (FTP) but not as capable or secure.
TKIP Temporal Key Integrity Protocol (TKIP) provides WPA with a data
encryption function. It ensures that a unique master key is
generated for each packet, supports message integrity and
sequencing rules and supports re-keying mechanisms.
triggers Triggers are used to deal with application protocols that create
separate sessions. Some applications, such as NetMeeting, open
secondary connections during normal operations, for example, a
connection to a server is established using one port, but data
transfers are performed on a separate connection. A trigger tells the
device to expect these secondary sessions and how to handle them.
Once you set a trigger, the embedded IP address of each incoming
packet is replaced by the correct host address so that NAT can
translate packets to the correct destination. You can specify

whether you want to carry out address replacement, and if so,
whether to replace addresses on TCP packets only, UDP packets
only, or both.
twisted pair The ordinary copper telephone wiring long used by telephone
companies. It contains one or more wire pairs twisted together to
reduce inductance and noise. Each telephone line uses one pair.
In homes, it is most often installed with two pairs. For Ethernet
LANs, a higher grade called Category 3 (CAT 3) is used for
10BASE-T networks, and an even higher grade called Category
5 (CAT 5) is used for 100BASE-T networks. See also 10BASE-T,
100BASE-T, Ethernet.
unnumbered interfaces
An unnumbered interface is an IP interface that does not have a
local subnet associated with it. Instead, it uses a router-id that
serves as the source and destination address of packets sent to
and from the router. Unlike the IP address of a normal interface,
the router-id of an unnumbered interface is allowed to be the
same as the IP address of another interface. For example, the
WAN unnumbered interface of your device uses the same IP
address of the LAN interface (192.168.1.1).
The unnumbered interface is temporary – PPP or DHCP will
assign a ‘real’ IP address automatically.
upstream The direction of data transmission from the user to the Internet.
USB Universal Serial Bus
A serial interface that lets you connect devices such as printers,
scanners, etc. to your computer by simply plugging them in. The
錯誤! 尚未定義樣式。 is equipped with a USB interface for
connecting to a stand-alone PC.
VC Virtual Circuit
A connection from your DSL router to your ISP.
VCI Virtual Circuit Identifier
Together with the Virtual Path Identifier (VPI), the VCI uniquely
identifies a VC. Your ISP will tell you the VCI for each VC they
provide. See also VC.
VPI Virtual Path Identifier
Together with the Virtual Circuit Identifier (VCI), the VPI uniquely
identifies a VC. Your ISP will tell you the VPI for each VC they
provide. See also VC.

(cross-references) to the other pages on that web site, as well as
to pages on other web sites. When a user accesses a web site,
the first page that is displayed is called the home page. See also
hyperlink, web site.
Web site A computer on the Internet that distributes information to (and
gets information from) remote users through web browsers. A
web site typically consists of web pages that contain text,

WEP Wired Equivalent Privacy (WEP) encrypts data over WLANs. Data
is encrypted into blocks of either 64 bits length or 128 bits length.
The encrypted data can only be sent and received by users with
access to a private network key. Each PC on your wireless network
must be manually configured with the same key as your device in
order to allow wireless encrypted data transmissions.
Eavesdroppers cannot access your network if they do not know
your private key. WEP is considered to be a low security option.
Wireless Wireless is a term used to describe telecommunications in which
electromagnetic waves (rather than some form of wire) carry the
signal over part or all of the communication path. See also
wireless LAN.
Wireless LAN A wireless LAN (WLAN) is one in which a mobile user can
connect to a local area network (LAN) through a wireless (radio)
connection. A standard, IEEE 802.11, specifies the technologies
for wireless LANs.
WPA Wi-Fi Protected Access
WPA is an initiative by the IEEE and Wi-Fi Alliance to address the
security limitations of WEP. WPA provides a stronger data
encryption method (called Temporal Key Integrity Protocol (TKIP)).
It runs in a special, easy-to-set-up home mode called Pre-Shared
Key (PSK) that allows you to manually enter a pass phrase on all
the devices in your wireless network. WPA data encryption is based
on a WPA master key. The master key is derived from the pass
phrase and the network name (SSID) of the device.
It provides improved data encryption and stronger user
authentication. The mode of WPA supported no your device is
called Pre-Shared Key (PSK), which allows you to manually enter a
type of key called a pass phrase.
WWW World Wide Web
Also called (the) Web. Collective term for all web sites anywhere
in the world that can be accessed via the Internet.
