Introduction
Congratulations on your purchases of the GemTek Wireless Broadband
Router. Your Wireless Broadband Router enables you to share your DSL or
Cable Internet connection with computers on your network. This guide will
explain the features and functions of the Wireless Broadband Router to help
you get the most out of your Internet experience.
GemTek’s Wireless Broadband Router allows LAN users to share a
single Internet Connection while providing the safety and security of port
blocking, packet filtering, and a natural firewall. Static address support,
integrated DHCP, PPPoE, and device name support will allow it to connect
to nearly any broadband provider whether Cable or DSL based, and at the
same time simplify local area network settings.
The Wireless Broadband Router provides two levels of security support.
First, it masks local users’ IPaddresses from others on the Internet making it
much more difficult for a hacker to target a machine on your network.
Secondly, it can block and redirect certain ports to limit the services that
outside users can access. Specific ports can be opened to ensure that games
and other Internet applications will run properly.
The Broadband Router provides special pass through support for
common VPN implementations. The Virtual Server feature allows you to
expose HTTP, FTP, Game Servers and other local services to be accessible
to Internet users located outside of the LAN. The User-Definable
Application Sensing Tunnel feature allows you to define the attributes to
support special applications requiring multiple connections, such as Internet
gaming, video conferencing, and Internet telephony. A DMZ setting can be
applied to a single client behind the Broadband Router to expose it to the
5
Internet and ensure complete Internet application compatibility even if
specific ports are not known.
Unlike proxy server or NAT software that requires the software server
to remain visible on the Internet, no local computers are directly externally
visible when using the Broadband Router. Also the Broadband Router, like
broadband, is always on, removing the need to constantly boot a software
server when access is desired from a client.
Integrated DHCP services allow up to 252 users to get their IP address
automatically on boot up from the Broadband Router. Client machines
require no software, simply set them to accept a dynamically assigned IP
address and reboot. Each time they are powered up the Broadband Router
will recognize them and set their IP address to instantly connect them to the
LAN.

Introduction to Broadband Router Technology
A router is a device that forwards data packets from a source to a
destination. Routers work on OSI layer 3, which forwards data packets using
an IP addresses and not a MAC address. A router will forward data from the
Internet to a particular computer on your LAN.
The information that makes up the Internet gets moved around using
routers. When you click on a link on a web page, you send a request to a
server to show you the next page. The information that is sent and received
from your computer is moved from your computer to the server using
routers. Arouter also determines the best route that your information should
follow to ensure that the information is delivered properly.
A router controls the amount of data that is sent through your network
by eliminating information that should not be there. This provides security
for the computers behind your router because computers from the outside
cannot access or send information directly to any computer on your network.
The router determines which computer the information should be forwarded
to and sends it. If the information is not intended for any computer on your
network, the data is discarded. This keeps any unwanted or harmful
information from accessing or damaging your network.
Introduction to Firewalls
A firewall is a device that sits between your computer and the Internet
that prevents unauthorized access to or from your network. Afirewall can be
a computer using firewall software or a special piece of hardware built
specifically to act as a firewall. In most circumstances, a firewall is used to
prevent unauthorized Internet users from accessing private networks such as
corporate LAN’s and Intranets.
7
A firewall watches all of the information moving to and from your
network and analyzes each piece of data. Each piece of data is checked
against a set of criteria that the administrator configures. If any data does not
meet the criteria, that data is blocked and discarded. If the data meets the
criteria, the data is passed through. This method is called packet filtering.
A firewall can also run specific security functions based on the type of
application or type of port that is being used. For example, a firewall can be
configured to work with an FTP or Telnet server. Or a firewall can be
configured to work with specific UDP or TCP ports to allow certain
applications or games to work properly over the Internet.
Introduction to Local Area Networking
Local Area Networking (LAN) is the term used when connecting
several computers together over a small area such as a building or group of
buildings. LAN’s can be connected over large areas. A collection of LAN’s
connected over a large area is called a Wide Area Network (WAN).
A LAN consists of multiple computers connected to each other. There
are many types of media that can connect computers together. The most
common media is CAT5 cable; UTP or STP twisted pair wire. On the other
hand, wireless networks do not use wires; instead they communicate over
radio waves. Each computer must have a Network Interface Card (NIC),
which communicates the data between computers. A NIC is usually a
10Mbps network card, 10/100Mbps network card, or a wireless network
card.
Most networks use hardware devices such as hubs or switches that each
cable can be connected to in order to continue the connection between
computers. A hub simply takes any data arriving through each port and
8
forwards the data to all other ports. A switch is more sophisticated, in that a
switch can determine the port that each piece of data is supposed to be
delivered to.A switch minimizes network traffic and speeds up the
communication over a network.
Networks take some time in order to plan and implement correctly.
There are many types of scenarios to consider which could affect the
operability of a network.
Introduction to Virtual Private Networking
Virtual Private Networking (VPN) uses a publicly wired network (the
Internet) to securely connect two different networks as if they were the same
network. For example, an employee can access the corporate network from
home using VPN, allowing the employee to access files and printers. Here
are several different implementations of VPN that can be used.
Point-to-Point Tunneling Protocol (PPTP)
PPTP uses proprietary means of connecting two private networks over the
Internet. PPTP is a way of securing the information that is communicated
between networks. PPTP secures information by encrypting the data inside
of a packet.
IPSecurity (IPSec)
IPSec provides a more secure network-to-network connection across the
Internet or a Wide Area Network (WAN). IPSec encrypts all communication
between the client and server whereas PPTP only encrypts the data packets.
Both of these VPN implementations are used because there is not a
9
standard for VPN server software. Because of this, each ISP or business can
implement their own VPN network making interoperability a challenge.
Introduction to Wireless Networking
GemTek wireless products are based on industry standards to provide
easy to use and compatible high-speed wireless connectivity within your
home or business. Strictly adhering to IEEE 802.11b the GemTek wireless
family of products will allow you to access the data you want, when and
where you want it. No longer will you be tethered to a workstation or forced
to run new wiring. You will be able to enjoy the freedom that wireless
networking delivers.
Standards Based Technology
Based on IEEE 802.11b, GemTek Air products can operate at the
maximum data rate of 11 Megabits per second. This means you will be able
to transfer large files quickly or even watch a Movie in MPEG format over
your network without noticeable delays. This technology works by using
multiple frequencies in the 2.4GHz range utilizing Direct Sequence Spread
Spectrum (DSSS) technology. GemTek Air products will automatically
sense the best possible connection speed to ensure the greatest speed and
range possible with the technology.
Installation Considerations
Designed to go up to 100 meters indoors and up to 300 meters outdoors,
GemTek Air lets you access your network from anywhere you want. Keep in
mind, however, that the number of walls, ceilings or other objects that the
wireless signals must pass thru will limit range. Typical ranges vary
10
depending on the types of materials and background RF noise in your home
or business. The key to maximizing range is to follow these basic principles:
1. Keep the number of walls and ceilings to a minimum - Each wall or
ceiling can reduce your GemTek Air Wireless products range from 1-30
meters. Position your Access Points, Residential Gateways, and
Computers so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between Access Points, Residential Gateways,
and Computers - A wall that is .5 meter thick, at a 45 degree angle
appears to be almost 1 meter thick. At a 2 degree angle it looks over 14
meters thick! Try to make sure that the AP and Adapters are positioned
so that the signal will travel straight through a wall or ceiling for better
reception.
3. Building Materials make a difference - A solid metal door or aluminum
studs may have a negative effect on range. Again, try to position Access
Points, Residential Gateways, and Computers so that the signal passes
through drywall or open doorways and not other materials.
4. Make sure that the antenna is positioned for best reception by using the
software signal strength tools included with your product.
5. Keep your product away (at least 1-2 meters) from electrical devices that
generate RF noise, like microwaves, Monitors, electric motors, etc.
For the average American 4-bedroom home, range should not be a
problem. If you experience low or no signal strength in areas of your
home that you wish to access, consider positioning the Access Point in a
location directly between the Residential Gateways and/or Computers
that will be connected. Additional Access Points can be connected to
provide better coverage in rooms where the signal does not appear as
strong as desired.
