Hareware Installation
Follow these ste ps to install the Wirele ss Access Point.
1. Choose a proper place for Access Point. In general, the best location is at the center
of your wi reless coverage area, within line of sight to all wireless devices. Keeping
cle ar of metal obstructions and away from direct sunlight.
2. Place the Access Point in the desired location. Normally, the higher you place the
antenna, the b etter the performance wi ll be. The antenna’s position enhances the
receiving sensitivi ty.
3. Attach one end of an RJ-45 E thernet cable to the Access Point and attach the other
end to a ne twork hub, switch, route r, or pa tch panel (possi bly on a wall).
4. Attach one end of the AC power adapter to the Access Point and the other end to a
powe r outlet. (Note: Only use the power adapter supplied by Gigabyte in the product
package. Using a different adapter may result in product damage.)
For the average home, si gnal range should not be an issue. I f you experience low or no
si gnal strength in areas of your home tha t you wish to access, consider posi tioning the
Access Point in a locati on directly between the computers with wireless adap ters. Additi onal Access Points can be conne cted to provide better coverage in rooms where the
signal does not appear as strong as desired.
Connect to Acce ss Point
Wired Ethernet Cable
You can connect a LAN cable from your computer’s Network card to the Access Point
without usi ng a Network switch or hub.

PC(AP Manager) 192.168.1.x
DHCP (Disable)
AP
192.168. 1.1(default)
1. You will need to assign a Stati c IP Address to the computer that you are using to
configure the Access Point on the same subnet.
For instance, the default IP address of the Access Point is 192.168.1.1 and the subnet
mask 2 55.255.255.0. You can enter I P address 192.168.1.20 (assuming that it is not
already assigned to another network device ), subnet mask 255.255.255.0 to your
computer.
Note: If you need the instructions on how to do this, please refer to Appendix C,
“Configuration of the PCs”
2. Connect to the Access Point one by one and assign a static IP to each Access Point.
For example, 192.168.1.2 or 192.168.1.y, etc. (If the IP address of your network is
10.1.5.x then your Access Point can be assigned to 10.1.5.y.)
PC(AP Manager) 192.168.1.x
DHCP (Disable)
192.168. 1.1 192.168.1.2

The re are two levels of encryp tion 64 bits and 128 bits. The 64 bits encryption is
referenced as a lower level encrypti on. The 128 bits encryption is referenced as a
hi gher level encryption.
The 64 bits WEP encryp tion use 4 0 bits as a secret key, which can controlled by
use r, and 24 bits as the initialize vector, whi ch user can not control. These two
portions plus together is 64 bi ts encryption. Some other vendor’s product might
refer as 40 bits encryption. It is the same thing.
The 128 bits WEP encrypti on use 104 bits as a secret key, which can controlled by
use r, and 24 bits as the initialize vector, whi ch user can not control. These two

Appendix A: Glossary
Access Point
An access po int is a wired controller that sends d ata to the wire less NICs installed in your
ne twork computers, and received data back from them. An AP is often connected to the
Ne twork comp uter that has I nternet access, or is directly connected to a A DSL or cable
modem.
ADSL
Asymmetri c digital subscriber line (ADSL) is a new modem technology that converts existing twisted-p air tele phone lines into access paths for high-speed communications of various sorts.
Auto-MD I/MDIX
On a network hub or switch, an auto-MDI/MDI X port automatically senses if it needs to act
as a MD I or MDIX port. The auto-MDI/MDIX capability eliminates the need for crosso ver
cables.
Auto-negotiate
To automatically determine the correct settings. The term is often used with communications and networki ng.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for automating
the configuration of computers that use TCP/IP. DHCP can be used to automatically assi gn IP addresses, to deliver TCP/IP stack config uration parameters such as the subnet
mask and default router, and to provide other configuration information such as the addresses for printer, time and news servers.
DSSS
Also known as “Dire ct Sequence Spread Spectrum,” this is a variety of radio transmission
methods tha t continuously change frequencies or signal patterns. Direct Sequence Spread
Spectrum (DSSS), which is used i n CDMA, multiplies the data bits by a very fast, pseudorandom b it p attern (PN sequence) tha t “spreads” the data into a large coded stream that
takes the full bandwid th of the channel.
45
GN-A16B Wireless Access Point User Guide
DNS
The Domain Name System (DNS) is a distributed I nternet directory service. DNS is used
mostly to translate betwe en domain names and IP addresses, and to control I nternet email
deli very. Most Internet services rely on DNS to work, and if DNS fails, web sites cannot be
located and email deli very stalls.
Dynamic IP Address
An I P address that is automatically assigned to a client station in a TCP/IP network,
typ ically by a DHCP server.
Firewall
A system desig ned to prevent unauthorized access to or from a private network. Firewalls
can be imp lemented in both ha rdware and software , or a combi nation of both. Firewalls
are frequently used to prevent unauthorized Internet users from accessing private
networks conne cted to the I nternet, especially intranets. All messages entering or leaving
the i ntranet pass through the firewall, which examines each message and blocks those
that do not meet the specified security criteria.
Gateway
A d evice, usually a router , that connects hosts on a local network to other networks.
IP Address
Every machi ne on the Internet has a unique identifying number, called an IP Address. A
typical I P address looks like this: 216.27.61.137
MAC Address
On a local area network (LAN) or other network, the MAC (Media Access Control) address
is your computer's unique hardware number. Usually written in the form 01:23:45:67:89:
ab
Ping (Packet In ternet Groper)
A utility to determine whether a specific IP address is accessible. It works by sending a
packet to the specified address and waiting for a reply. PING is used primarily to troubleshoot I nternet connections.
Router
A d evice that forward s data packets alo ng networks. A router is connected to at least two
ne tworks, commonly two LANs or WANs or a LAN and its I SP’s network. Routers are
located at gateways, the places where two or more networks connect.
46
GN-A16B Wireless Access Point User Guide
SSID
The SSID is the name repre sent the route r in the wireless network.
Subnet Mask
A mask used to determi ne what subnet an IP address belongs to. An IP address has two
components, the network address and the host address. Subnetting enables the network
administrator to further divide the host part of the address into two or more subnets.
TCP/IP
TC P/IP (Transmission Control Protocol/Internet Protocol), the suite of communications
protocols used to connect hosts on the Internet.
WAN
Wi de Area Network, a communication network that covers a relatively large geographic
area, consisting of two or more LANs. Broadband communication over the WAN is often
throug h public ne tworks such as the ADSL or Cable systems, or through leased lines or
satellites. In its most basi c definition, the I nternet could be considered a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a 64/128-bit shared
key algori thm, as described in the IEEE 802.11 standard.
