About This Manual
This manual provides descriptions of the Conceptronic C300GBRS4 802.11n Wireless Gigabit
Broadband Router, its hardware and software features, and how to set up and use the device
on your small office or home network.
Before You Start
Please read and make sure you understand all the prerequisites for proper installation of your
new Wireless Broadband Router. Have all the necessary information and equipment on hand
before starting the installation. A packing list is included at the end of this section.
Installation Overview
The procedure to install the Wireless Broadband Router can be described in general terms in
the following steps:
1. Gather information and equipment needed to install the device. Check the contents of the
package to be certain that everything listed on the packing list is included. A packing list
is included at the end of this section. The information you will need includes the account
name or number and the password used to gain access to your service provider’s network,
and ultimately to the Internet.
2. Install the hardware, that is, connect the Ethernet cables to the device to establish the
necessary network links to your computer and connect the power adapter to power on the
Wireless Broadband Router.

Requirements for Installation
To install and use the Wireless Broadband Router you need a computer equipped with an
Ethernet port (such as an Ethernet NIC) and a web browser.
WLAN Ethernet Adapter
Any computer that uses the Wireless Broadband Router must be able to connect to it through
the Wireless Ethernet (WLAN) on the Wireless Broadband Router. This connection is a Wireless
Ethernet (WLAN or WiFi) connection and therefore requires that your computer be equipped
with a Wireless Ethernet Adapter as well. Many notebook computers are now sold with a
Wireless Ethernet Adapter already installed. There is also a Wired Ethernet port that is used
to connect the WLAN adapter to your wired network. This port can be used to configure the
Wireless Broadband Router. Most fully assembled desktop computers come with an Ethernet
NIC adapter as standard equipment. If your computer does not have an Ethernet port, you
must install an Ethernet NIC adapter before you can configure the Wireless Broadband Router.
If you must install an adapter, follow the installation instructions that come with the Ethernet
NIC adapter.
Operating System
The Wireless Broadband Router uses an HTML-based web interface for setup and
management. The web configuration manager may be accessed using any operating system
capable of running web browser software.
Web Browser
Any common web browser can be used to configure the Wireless Broadband Router using the
web configuration management software. The program is designed to work best with more
recently released browsers such as Microsoft Internet Explorer® version 6.0, Netscape
Navigator® version 6.2.3, or later versions. The web browser must have JavaScript enabled.
JavaScript is enabled by default on many browsers. Make sure JavaScript has not been
disabled by other software (such as virus protection or web user security packages) that may
be running on your computer.

Packing List
Open the shipping carton and carefully remove all items. Make sure that you have the items
listed here.
•One Conceptronic C300GBRS4 - 802.11n Wireless Gigabit Broadband Router
•Three Antennas for C300GBRS4
•One CD-ROM containing this User’s Guide
•One Straight-through Ethernet cable
•One Power Adapter, 5V, 3A DC
•One Quick Installation Guide
•One Warranty Card
Wireless LAN
A Wireless LAN is a cellular computer network that transmits data using radio signals instead
of cables. Wireless LAN technology is commonly used for home, small office and large
corporate networks. Wireless LAN devices have a high degree of mobility and flexibility that
allow network to be quickly set up or dismantled and allow them to roam freely throughout
the network.
The IEEE 802.11n Wireless LAN standard is an improvement on the IEEE 802.11g standard. The
802.11n embedded Wireless LAN access point is fully compatible with legacy IEEE 802.11b and
IEEE 802.11g devices.
Some basic understanding of wireless technology and terminology is useful when you are
setting up the Wireless Broadband Router or any wireless access point. If you are not familiar
with wireless networks please take a few minutes to learn the basics.
For home users who will not incorporate a RADIUS server in their network, the security for the
Conceptronic C300GBRS4, used in conjunction with other WPA-compatible 802.11 products,
will still be much stronger than ever before. Utilizing the Pre-Shared Key mode of WPA, the
Wireless Broadband Router will obtain a new security key every time it connects to the 802.11
network. You only need to input your encryption information once in the configuration menu.
No longer will you have to manually input a new WEP key frequently to ensure security. With
the Wireless Broadband Router, you will automatically receive a new key every time you
connect, vastly increasing the safety of your communication.
The Wireless Broadband Router is an ideal solution for quickly creating and extending a
wireless local area network (WLAN) in offices or other workplaces, trade shows and special
events. The 802.11n standard is backwards compatible with 802.11b and 802.11g devices.
The Wireless Broadband Router has the newest, strongest, most advanced security features
available today. When used with other 802.11n WPA (WiFi Protected Access) compatible
products in a network with a RADIUS server, the security features include:
WPA: WiFi Protected Access, which authorizes and identifies users, based on a secret key
that change automatically at regular intervals. WPA uses TKIP (Temporal Key Integrity
Protocol) to change 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. (By contrast, the previous WEP encryption implementation required the keys to be
changed manually.)

Radio Transmission
Wireless LAN devices use electromagnetic waves within a broad, unlicensed range of the radio
spectrum to transmit and receive radio signals. When a wireless access point is present, it
becomes a base station for the Wireless LAN nodes in its broadcast range. Wireless LAN nodes
transmit digital data using FM (frequency modulation) radio signals. Wireless LAN devices
generate a carrier wave and modulate this signal using various techniques. In this way, digital
data can then be superimposed onto the carrier signal. This radio signal carries data to
Wireless LAN devices within range of the transmitting device. The antennae of Wireless LAN
devices listen for and receive the signal.
Range
Range should not be a problem in most homes or small offices. If you experience low or no
signal strength in some areas, consider positioning the device in a location between the
Wireless LAN devices maintaining a roughly equal straight-line distance to all devices that
need to access the Wireless Broadband Router through the wireless interface. Adding more
802.11n access points to rooms where the signal is weak can improve signal strength.
SSID
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within
the range of the network. Wireless devices that wish to communicate with each other must
use the same SSID. Several Wireless Broadband Routers or access points can be set up using
the same SSID so that wireless stations can move from one location to another without losing
connection to the wireless network.
The Wireless Broadband Router operates in Infrastructure mode. It controls network access on
the wireless interface in its broadcast area. It will allow access to the wireless network to
devices using the correct SSID after a negotiation process takes place. The Conceptronic
C300GBRS4 broadcasts its SSID so that any wireless station in range can learn the SSID and ask
permission to associate with it. Many wireless adapters are able to survey or scan the wireless
environment for access points. An access point in Infrastructure mode allows wireless devices
to survey that network and select an access point with which to associate.

Hardware Installation
Place the Wireless Broadband Router in a location where it can be easily connected to the
wired interface (Ethernet link to a broadband modem, for example) as well as function
effectively as a Wireless LAN access point. Make sure the Wireless Broadband Router is near a
suitable power source.
Connect the bundled power supply to the power connection on the back of the C300GBRS4
and to a free wall power outlet. The Power LED of the C300GBRS4 will turn on.
Wireless LAN Performance and Environment
Many environmental factors can affect the effective wireless function of the Wireless
Broadband Router. If this is your first time setting up a wireless network device, read and
consider the points listed below.
The Wireless Broadband Router can be placed on a shelf or desktop, ideally you should be
able to see the LED indicators on the front if you need to view them for troubleshooting.
The Wireless Broadband Router lets you access your network within range of the device.
However, walls, ceilings, or other objects that the wireless signals must pass through can
limit signal range. Typical ranges vary depending on the types of materials and background RF
noise in your home or business. For maximum range and signal strength, use these basic
guidelines:
1. Keep the number of walls and ceilings to a minimum:
The signal emitted from Wireless LAN devices can penetrate through ceilings and walls.
However, each wall or ceiling can reduce the range Wireless LAN devices from 1 to 30M.
Position your wireless devices so that the number of walls or ceilings obstructing the signal
path is minimized.
2. Consider the direct line between access points and workstations:
A wall that is 0.5 meters thick, at a 45-degree angle appears to be almost 1 meter thick.
At a 2-degree angle, it is over 14 meters thick. Be careful to position access points and
client adapters so the signal can travel straight through (90º angle) a wall or ceiling for
better reception.
3. Building Materials make a difference:
Buildings constructed using metal framing or doors can reduce effective range of the
device. If possible, position wireless devices so that their signal can pass through drywall
or open doorways, avoid positioning them so that their signal must pass through metallic
materials. Poured concrete walls are reinforced with steel while cinderblock walls may
have little or no structural steel.
4. Keep the Wireless Broadband Router away (at least 1-2 meters) from electrical
devices:
Position wireless devices away from electrical devices that generate RF noise such as
microwave ovens, monitors, electric motors, etc.
5. Position antenna for best reception:
Adjust the antenna position to see if the signal strength improves. Some adapters or
access points allow the user to judge the strength of the signal. Use this method, if
available, to test signal strength.
