Description
Profile name
Define a recognizable profile name for you to
identify the different networks. It can be any
phrase to help you remember.
The SSID is the unique name identified in a
WLAN. The ID prevents the unintentional merging
of two co-located WLANs. You may specify a
SSID for the adapter and then only the device
with the same SSID can interconnect to the
adapter.
This field will be filled as the access point you
selected when SSID is not hidden and grayed out.
If SSID is hidden, you have to input correct SSID
yourself.
There are two kinds of network types described
as follows.
Infrastructure – This operation mode requires
the presence of an 802.11 Access Point. All
communication is done via the Access Point or
Router.
Network Name (SSID)
This is a
computer-to-computer
(ad hoc) network
Ad Hoc – Connect to another wireless adapter in
the Wireless LAN network without an Access
Point or Router.
Check this box if you wish to connect to another
computer / network device by ad hoc method.
When not accessing the wireless access point,
you have to check this box.

Authentication
This setting is only available for Ad Hoc mode.
Select the number of the radio channel used for
networking. The channel setting should be the
same with the network you are connecting to.
This setting has to be consistent with the wireless
networks that the adapter intends to connect.
Open System – No authentication is needed
among the wireless network.
21
DG-WN3300N User Manual
Shared Key – Only wireless stations using a
shared key (WEP Key identified) are allowed to
connect to each other.
WPA-PSK – It is a special mode designed for
home and small business users who do not have
access to network authentication servers. In this
mode, known as Pre-Shared Key, the user
manually enters the starting password in their
access point or gateway, as well as in each
wireless station in the network. WPA-PSK takes
over automatically from that point, keeping
unauthorized users that don’t have the matching
password from joining the network, while
encrypting the data traveling between authorized
devices.
WPA2-PSK – WPA2-PSK is also for home and
small business. The difference between
WPA-PSK and WPA2-PSK is that WPA2-PSK
provides data encryption via the AES by default.
In contrast, WPA-PSK uses Temporal Key
Integrity Protocol (TKIP) by default.
WPA 802.1X – WPA provides a scheme of mutual
authentication
using
either
IEEE
802.1x/Extensible Authentication Protocol (EAP)
authentication or pre-shared key (PSK)
technology. It provides a high level of assurance
to enterprises, small businesses and home users
that data will remain protected and that only
authorized users may access their networks. For
enterprises that have already deployed IEEE
802.1x authentication, WPA offers the advantage
of leveraging existing authentication databases
and infrastructure.
WPA2 802.1X – Like WPA, WPA2 supports IEEE
802.1x/EAP authentication or PSK technology. It
also includes a new advanced encryption
mechanism using the Advanced Encryption
22
DG-WN3300N User Manual
Standard (AES). AES is required to the corporate
user or government users. The difference
between WPA and WPA2 is that WPA2 provides
data encryption via the AES by default. In
contrast, WPA uses Temporal Key Integrity
Protocol (TKIP) by default.
Data encryption
WEP 802.1X – It’s a special mode for using IEEE
802.1x/EAP technology for authentication and
WEP keys for data encryption.
Disabled – Disable the WEP Data Encryption.
WEP – Enable the WEP Data Encryption. When
the item is selected, you have to continue setting
the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol)
changes the temporal key every 10,000 packets
(a packet is a kind of message transmitted over a
network.) This insures much greater security than
the standard WEP security.
AES – AES has been developed to ensure the
highest degree of security and authenticity for
digital information and it is the most advanced
solution defined by IEEE 802.11i for the security
in the wireless network.
Note: All devices in the network should use the
same encryption method to ensure the
communication. Select the data encryption type
from drop-down menu. This setting must be
identical with the setting of wireless access point
you wish to connect.
ASCII / PASSPHRASE
When the encryption type is ‘WEP’, it’s required to
input a set of ‘passphrase’ to connect to the
wireless access point. Check ‘ASCII’ or
‘PASSPHRASE’ depends on the security setting
of access point, and input it in the box; if you
select ‘PASSPHRASE’ you also need to select
23
DG-WN3300N User Manual
the length of the key.
The passphrase must be identical with the setting
of wireless access point you wish to connect.
Key index
Select WEP key index. For most of the access
points you can select ‘1’, but please refer to the
setting of the access point.
Network key /
Confirm network key
When the encryption type is ‘WPA’ or
‘WPA2-PSK’, it’s required to input a network key
to connect to the wireless access point. Please
input the same network key in the ‘confirm
network key’ box.
When authentication type is any of 802.1X, you
have to select EAP type, tunnel, and provision
mode from dropdown menu. This setting must be
identical with your 802.1x authentication server.
EAP TYPE
Provision Mode
GTC – GTC is an authentication protocol which
allows the exchange of clear text authentication
credentials across the network.
TLS – TLS is the most secure of the EAP
protocols but not easy to use. It requires that
digital certificates be exchanged in the
authentication phase. The server presents a
certificate to the client. After validating the
server’s certificate, the client presents a client
certificate to the server for validation.
LEAP – LEAP is a pre-EAP, Cisco-proprietary
protocol, with many of the features of EAP
protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should
be selected for use only when limited vendor
choice for client, access-point, and server
products is not a concern. When you have set up
LEAP authentication, you have to enter the user
name and password of your computer.

PEAP & TTLS – PEAP and TTLS are similar and
easier than TLS in that they specify a stand-alone
authentication protocol be used within an
encrypted tunnel. TTLS supports any protocol
within its tunnel, including CHAP, MSCHAP,
MSCHAPv2 and PAP.
PEAP specifies that an EAP-compliant
authentication protocol must be used; this
adaptor supports MD5, TLS, GTC (Generic Token
Card) and MSCHAPv2. The client certificate is
optional required for the authentication.

WPA-PSK and WPA2-PSK is that WPA2-PSK
provides data encryption via the AES by default.
34
DG-WN3300N User Manual
In contrast, WPA-PSK uses Temporal Key
Integrity Protocol (TKIP) by default.
WPA 802.1X – WPA provides a scheme of mutual
authentication
using
either
IEEE
802.1x/Extensible Authentication Protocol (EAP)
or pre-shared key (PSK) technology. It provides a
high level of assurance to enterprises, small
businesses and home users that data will remain
protected and that only authorized users may
access their networks. For enterprises that have
already deployed IEEE 802.1x authentication,
WPA offers the advantage of leveraging existing
authentication databases and infrastructure.
WPA2 802.1X – Like WPA, WPA2 supports IEEE
802.1x/EAP authentication or PSK technology. It
also includes a new advanced encryption
mechanism using the Advanced Encryption
Standard (AES). AES is required to the corporate
user or government users. The difference
between WPA and WPA2 is that WPA2 provides
data encryption via the AES by default. In
contrast, WPA uses Temporal Key Integrity
Protocol (TKIP) by default.
Data encryption
WEP 802.1X – It’s a special mode for using IEEE
802.1x/EAP technology for authentication and
WEP keys for data encryption.
Disabled – Disable the WEP Data Encryption.
WEP – Enable the WEP Data Encryption. When
the item is selected, you have to continue setting
the WEP Encryption keys.
TKIP – TKIP (Temporal Key Integrity Protocol)
changes the temporal key every 10,000 packets
(a packet is a kind of message transmitted over a
network.) This insures much greater security than
the standard WEP security.
AES – AES has been developed to ensure the
highest degree of security and authenticity for
35
DG-WN3300N User Manual
digital information and it is the most advanced
solution defined by IEEE 802.11i for the security
in the wireless network.
Note: All devices in the network should use the
same encryption method to ensure the
communication. Select the data encryption type
from the drop-down menu. This setting must be
identical with the setting of wireless access point
you wish to connect.
ASCII / PASSPHRASE
When the encryption type is ‘WEP’, it’s required to
input a set of ‘passphrase’ to connect to wireless
access point. Check ‘ASCII’ or ‘PASSPHRASE’

have to select EAP type, tunnel, and provision
mode from dropdown menu. This setting must be
identical with your 802.1x authentication server.
EAP TYPE
Provision Mode
GTC – GTC is an authentication protocol which
allows the exchange of clear text authentication
credentials across the network.
TLS – TLS is the most secure of the EAP
protocols but not easy to use. It requires that
36
DG-WN3300N User Manual
digital certificates be exchanged in the
authentication phase. The server presents a
certificate to the client. After validating the
server’s certificate, the client presents a client
certificate to the server for validation.
LEAP – LEAP is a pre-EAP, Cisco-proprietary
protocol, with many of the features of EAP
protocols. Cisco controls the ability of other
vendors to implement this protocol, so it should
be selected for use only when limited vendor
choice for client, access-point, and server
products is not a concern. When you have set up
LEAP authentication, you have to enter the user
name and password of your computer.
Tunnel

PEAP & TTLS – PEAP and TTLS are similar and
easier than TLS in that they specify a stand-alone
authentication protocol be used within an
encrypted tunnel. TTLS supports any protocol
within its tunnel, including CHAP, MSCHAP,
MSCHAPv2 and PAP.
PEAP specifies that an EAP-compliant
authentication protocol must be used; this
adaptor supports MD5, TLS, GTC (Generic Token
Card) and MSCHAPv2. The client certificate is
optional required for the authentication.
Includes MD5, GTC, TLS and MSCHAP-v2 when

IEEE 802.11n standard: 802.11n will work by utilizing multiple wireless
antennas in tandem to transmit and receive data. The associated term MIMO
(Multiple Input, Multiple Output) refers to the ability of 802.11n and similar
technologies to coordinate multiple simultaneous radio signals. MIMO
increases both the range and throughput of a wireless network. An additional
technique employed by 802.11n involves increasing the channel bandwidth.
IEEE 802.11g standard: 802.11g is the new IEEE standard for high-speed
wireless LAN communications that provides for up to 54 Mbps data rate in the
2.4 GHz band. 802.11g is quickly becoming the next mainstream wireless LAN

802.11g defines the use of the same OFDM modulation technique specified in
IEEE 802.11a for the 5 GHz frequency band and applies it in the same 2.4 GHz
frequency band as IEEE 802.11b. The 802.11g standard requires backward
compatibility with 802.11b.
The standard specifically calls for:
A. A new physical layer for the 802.11 Medium Access Control (MAC) in
the 2.4 GHz frequency band, known as the extended rate PHY (ERP).
The ERP adds OFDM as a mandatory new coding scheme for 6, 12
and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps
(optional speeds). The ERP includes the modulation schemes found in
802.11b including CCK for 11 and 5.5 Mbps and Barker code
modulation for 2 and 1 Mbps.
B. A protection mechanism called RTS/CTS that governs how 802.11g
devices and 802.11b devices interoperate.
IEEE 802.11b standard: The IEEE 802.11b Wireless LAN standard
subcommittee, which formulates the standard for the industry. The objective is
to enable wireless LAN hardware from different manufactures to communicate.
Ad-hoc: An Ad-hoc integrated wireless LAN is a group of computers, each has
a Wireless LAN card, Connected as an independent wireless LAN. Ad hoc
wireless LAN is applicable at a departmental scale for a branch or SOHO
operation.
Infrastructure: An integrated wireless and wired LAN is called an
infrastructure configuration. Infrastructure is applicable to enterprise scale for
wireless access to central database, or wireless application for mobile workers.

BSS ID: A specific Ad-hoc LAN is called an Independent Basic Service Set
(IBSS) wherein the wireless devices directly communicate with each other
without a central AP/ router.
WEP: WEP is Wired Equivalent Privacy, a data privacy mechanism based on a
40 bit shared key algorithm, as described in the IEEE 802 .11 standard.
TKIP: TKIP is a quick-fix method to quickly overcome the inherent weaknesses
in WEP security, especially the reuse of encryption keys. TKIP is involved in the
IEEE 802.11i WLAN security standard, and the specification might be officially
released by early 2003.
AES: 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. Compare with AES,
TKIP is a temporary protocol for replacing WEP security until manufacturers
implement AES at the hardware level.
DSSS and FHSS: Frequency-hopping spread-spectrum (FHSS) uses a
narrowband carrier that changes frequency in a pattern that is known to both
transmitter and receiver. Properly synchronized, the net effect is to maintain a
single logical channel. To an unintended receiver, FHSS appears to be
short-duration impulse noise.
Direct-sequence spread-spectrum (DSSS) generates a redundant bit pattern
for each bit to be transmitted. This bit pattern is called a chip (or chipping code).
The longer the chip is, the greater the probability that the original data can be
recovered. Even if one or more bits in the chip are damaged during
transmission, statistical techniques embedded in the radio can recover the
original data without-the need for retransmission. To an unintended receiver,
DSSS appears as low power wideband noise and is rejected (ignored) by most
narrowband receivers.
Spread Spectrum: Spread Spectrum technology is a wideband radio
frequency technique developed by the military for use in reliable, secure,
mission-critical communication systems. It is designed to trade off bandwidth
efficiency for reliability, integrity, and security. In other words, more bandwidth is
consumed than in the case of narrowband transmission, but the trade off
produces a signal that is, in effect, louder and thus easier to detect, provided
that the receiver knows the parameters of the spread-spectrum signal being
broadcast. If a receiver is not tuned to the right frequency, a spread –spectrum
signal looks like background noise. There are two main alternatives, Direct

Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum
(FHSS).
WPS: WPS stands for Wi-Fi Protected Setup. It provides a simple way to
establish unencrypted or encrypted connections between wireless clients and
access point automatically. User can press a software or hardware button to
activate WPS function, and WPS-compatible wireless clients and access point
will establish connection by themselves. There are two types of WPS: PBC
(Push-Button Configuration) and PIN code.
