CHAPTER 1: Introduction
Congratulations on your purchase of Atlantis Land Wireless Broadband Router.
This integrated access device combines Internet gateway functions with wireless
LAN and Fast Ethernet switch. It provides a complete solution for Internet surfing
and office resources sharing, and it is easy to configure and operate for every
users.
This manual discusses how to install the IEEE 802.11g Wireless Broadband
Router.
1.1 An Overview of the del Wireless Broadband Router
With the explosive growth of the Internet, accessing information and services at
any time, day or night has become a standard requirement for most people. The
era of the standalone PC is waning. Networking technology is moving out of the
exclusive domain of corporations and into homes with at least two computers.
This integrated access device combines Internet gateway functions with wireless
LAN and Fast Ethernet switch. Designed for the business and home, it saves you
the cost of installing a separate modem and ISP line for each computer, while
providing ready connection for the users, with or without the network wires.
Broadband network access is also gaining ground. However, allowing more than
two computers to access the Internet at the same time means less affordable,
higher costs. Thus, there is a need to share one legal IP address over a single
Internet connection to link the home with the Internet.
The scarcity of IP addresses and using a shared Internet connection through an
Internet sharing device can solve high network access costs. All linked computers
can make full use of broadband capabilities over such a device.
This device not only comes equipped with a wide range of features, but also can
be installed and configured right out of the box. This device supports a simple
local area network and Internet access share, offering great cost savings.
The local area network connects up home computers while also allowing any of
the computers to access the Internet, share resources, or play online games—the
basis of the family computing lifestyle.

geographical area. You may have a choice of channels (for your
region) so you should use a different channel than an adjacent AP
(access point) to reduce interference. Interference occurs when
radio signals from different access points overlap causing
interference and degrading performance.
Adjacent channels partially overlap however. To avoid interference
due to overlap, your AP should be on a channel at least five
channels away from a channel that an adjacent AP is using. For
example, if your region has 11 channels and an adjacent AP is
using channel 1, then you need to select a channel between 6 or
11

3.7.2 Virtual Server
Being a natural Internet firewall, this Wireless Broadband Router protects your
network from being accessed by outside users. When it needs to allow outside
users to access internal servers, e.g. Web server, FTP server, E-mail server or
News server, this modem can act as a virtual server. You can set up a local
server with specific a port number that stands for the service, e.g. Web (80), FTP
(21), Telnet (23), SMTP (25), POP3 (110), When an incoming access request to
the router for a specified port is received, it will be forwarded to the corresponding
internal server.
For example, if you set the Service Port number 80 (Web) to be mapped to the IP
Address 192.168.1.2, then all the http requests from outside users will be
forwarded to the local server with IP address of 192.168.1.2. If the port is not
listed as a predefined application, you need to add it manually.
The Virtual Sever profiles are listed in the table at the bottom of the page.
Enable: Click to enable or disable the virtual server.
A02-RB-W54 Pag. 49
Wireless Broadband Router
Name: Type a descriptive name for the virtual server.
Protocol: Select a protocol (TCP or UDP) to use for the virtual server.
Private Port: Type the port number of the computer on the LAN that is being
used to act as a virtual server.
Public Port: Type the port number on the WAN that will be used to provide
access to the virtual server.
LAN Server: Type the LAN IP address that will be assigned to the virtual server.
Add: Click to add the virtual server to the table at the bottom of the screen.
Update: Click to update information for the virtual server if the user has selected
a listed item and has made changes.
Delete: Select a listed item and click “Delete” to remove the item from the list.
Clear: Click to erase all fields and enter new information.
If the DHCP server option is enabled, you have to be very careful in
assigning the IP addresses of the virtual servers in order to avoid
conflicts. The easy way is that the IP address assigned to each
virtual server should not fall into the range of IP addresses that are
to be issued by the DHCP server. You can configure the virtual
server IP address manually, but it is still in the same subnet with the
router.

Spread Spectrum technology is a wideband radio frequency
technique developed by the military for use in reliable, secure,
mission-critical communications 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).
Question
Answer
What is DSSS? What is FHSS? And what are their
differences?
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 SpreadSpectrum (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, 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.

Question
Answer
Would the information be intercepted while transmitting on
air?
WLAN features two-fold protection in security. On the
hardware side, as with Direct Sequence Spread Spectrum
technology, it has the inherent security feature of scrambling.
On the software side, WLAN offers the encryption function
(WEP) to enhance security and access control.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism
based on a 64-bit or 128-bit shared key algorithm, as
described in the IEEE 802.11 standard.
What is WPA?
Attempting IEEE802.11i standard, Wi-Fi Alliance has chosen
from preliminary version a group of specifications called WPA
(Wi-Fi Protected Access).
Specifications of WPA are:
Question
Answer
• TKIP Integration (Temporal Key Integrity Protocol) to
allow key change dinamically and integrity control of
packets.
• Advanced mechanism to manage authentication and
access control to network services in centralized
mode (802.11x through EAP, TLS use is necessary)
• Authentication key is different to key used for
encryption
This protocol is more strong that WEP encryption.
What is WPA2?
Recently approved by Wi-Fi Alliance, the new standard WPA2
is an evolution of WPA (Wi-Fi Protected Access), supported
by almost compatible IEEE802.11g clients.
WPA standard, required to repair WEP weakness, has only a

part of 802.11i specifics.
WPA2 introduce all IEEE802.11i specifics, like support for
Advanced Encryption Standard (AES), encryption protocol
use also in VPN IpSEC.
WPA2 devices will be compatible with WPA device, but they
will be updated through new driver and firmware.
NetFly AP2-54M supports WPA2 without performance
reduction.

Answer
What is the impact of these algorithms of encryption on
performance?
Chipset guarantee the full hardware support, without
performance reduction, of almost recent security standard,
like Wi-Fi Protected Access (WPA/WPA2) and IEEE802.11i.
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the
wireless network is configured to communicate with a wired
network through a wireless access point.
What is roaming?
Roaming is the ability of a portable computer user to
communicate continuously while moving freely throughout an
area greater than that covered by a single access point.
Before using the roaming function, the workstation must make
sure that it is the same channel number with the access point
of dedicated coverage area.
Question
Answer
Question
Answer
What is ISM band?
The FCC and their counterparts outside of the U.S. have set
aside bandwidth for unlicensed use in the ISM (Industrial,
Scientific and Medical) band. Spectrum in the vicinity of 2.4
GHz, in particular, is being made available worldwide. This
presents a truly revolutionary opportunity to place convenient
high-speed wireless capabilities in the hands of users around
the globe.
What is the IEEE 802.11g standard?
Approved in June, 2003 as an IEEE standard for wireless
A02-RB-W54 Pag. 74
Wireless Broadband Router
local area networks (WLANs), 802.11g offers wireless
transmission over relatively short distances at up to 54
megabits per second (Mbps) compared with the 11 megabits
per second of the 802.11b (Wi-Fi) standard. Like 802.11b,
802.11g operates in the 2.4 GHz range and is thus compatible
with it.
Question

Question
Answer
What is WDS?
WDS (Wireless Distribution System) is a technology that allow
at a pair of Wireless Multi-Function APs operating under
Bridge mode to act as the bridge that connect two Ethernet
networks or Ethernet enabled clients together. Repeat Mode
is able to extend the effective range and coverage of the
wireless network.
Why 2 AP trasmitting on different channel making
interferences?
Every channel occupies about 22Mhz; being ISM band made
of 80 Mhz, you can utilize only 3 channel without overlap.
We suggest to set AP with 5 channel interval between 2 AP
utilized. (ex. AP1-channel 1, AP2-channel6).
Interferences are making when 2 or more channels overlap
themselves.

Does IEEE802.11b clients works properly with AP
IEEE802.11g?
It is possible to use IEEE802.11b clients with IEEE802.11g
Access Point.
Performance will be reducing to 11Mbps to guarantee full
compatibility with IEEE802.11b.
A02-RB-W54 Pag. 75

emissions.
May I use a cable to improve antenna standing?
Answer
Question
Answer
Yes, it is possible.
It’s necessary to know that every cable induce attenuation
(dB/m).
A very long cable should be made useless a positive effect
generate by antenna’s gain.
