GN-A11G Wireless LAN Access Point
Hardware installation
Use the following steps to install Access Points (hereafter called APs).
1. Please select an appropriate location to install AP. Generally, a center
covering radio signals from all radio equipment is the best location. Please
eliminate all metal objects within the coverage and prevent direct sunlight.
2. Please locate the AP appropriately. Generally, the higher the antenna is
located, the better the efficiency of AP is. The location of antenna influences
the sensitiveness of signal reception.
3. Connect one end of RJ-45 Ethernet cable to AP and the other end to a hub,
converter, router or wiring panel (normally fixed on the wall).
4. Connect one end of power adapter to AP and the other end to a socket.
(Note: please only use the power adapter provided in the Gigabyte’s
package; the device may be damaged if a different adapter is used.)
As for normal households, the range of signal receiption should not be an issue.
In case of non- or weak signals where the wireless LAN is used, please consider
to place the AP directly between the computer and wireless adaptor. An external
AP can be connected for rooms out of the coverage to build up a better
environment of reception.
Connecting AP
Linking wired Ethernet
You can directly connect built-in adaptor to AP with a cable instead of a
converter or hub.

GN-A11G Wireless LAN Access Point
There are two installation methods for reference:
Method 1: Static IP address
If DHCP is not used on the network, the AP can be set up via a direct
connection to the computer.
PC (AP Manager) 192.168.1.x
192.168.1.1 (Default)
Access Point
1. You must assign a static IP address to the computer. The Subnet must be
the same for the computers and AP. For example, the default IP address of
the AP is 192.168.1.1 and the Subnet Mask is 255.255.255.0. You can enter
an IP address of 192.168.1.20 (if not assigned to other network equipments)
and an Subnet Mask of 255.255.255.0.
Note: For further instructions regarding to this step, please refer to
Appendix C, Computer Configuration.
2. Please connect APs in turns and assign a static IPs to each AP. For
example, 192.168.1.2 or 192.168.1.y. (If the IP address is 10.1.5.x, 10.1.5.y
can be assigned to your AP.)
3. Please make sure an exclusive IP for each AP.
4. After setting all APs successfully, you can use AP manager to control /
monitor all APs.

Method 2: Multi-AP configuration
Use a DHCP server to set IP address and then remove the server.
To set up multi APs at one time, a DHCP server can be set up to assign IPs for
all APs. Therefore, each AP has its exclusive IP address. After setting, please
remove or disable the DHCP server. Now, you can search all APs with AP
Manager and assign a static IP address for the Nth AP. Note: after assigning a
static IP address for each AP, please set the AP Manager in the same Subnet.

Converter/Hub
Converter/Hub
Obtain an IP address automatically – DHCP server is enabled
If a DHCP server is used on the network, it can connect to APs and AP Manager
through converters /hubs. You should set the IP address of AP as “Obtain an IP
address automatically”. DHCP will assign an IP address to the AP. The Subnet
must be the same for the PC(AP Manager) and AP. Or, you can set the PC (AP
Manager) as “Obtain an IP address automatically” and assign IPs with the same
DHCP.

party generates its own shared key and asks the
receiver to accept the (usually randomly) key. Once
accepted, this key is used for a short time only, then a
new key is generated.
Shared Key
The sender and the recipient share a key.
If you select “Shared Key” or “Both”, the WEP option, “Disable”, will not be

GN-A11G Wireless LAN Access Point
WPA
If you have used Wi-Fi for a while, you may be familiar with
802.1X Authentication Protocol, which allows users to authenticate the
wireless network via RASIUS server. 802.1X Authentication Protocol is an
option in standard Wi-Fi but a must for WPA. If a RADIUS server is
not avaiable in your environment, regardless of the needs of
802.1X, you can use WPA. As another option for RADIUS
server, WPA supports pre-shared key.
WPA-PSK As for the security of traditional WEP, it is very inconvenient to
change encrypted keys. Even you change encrypted keys any
time; you still can not select all APs and wireless LAN adapter
while changing encrypted keys.
Instead, rekeying is a tedious manual process and is completely
impractical for large organizations. After all, the instant you
rekey an access point, none of the clients will be able to access
it until they are also rekeyed.
But with WPA, the rekeying of global encryption keys is required.
In the case of unicast traffic, the encryption key is changed after
every frame using Temporary Key Integrity Protocol (TKIP). This
protocol allows key changes to occur on a frame-by-frame basis
and to be automatically synchronized between the access point
and the wireless client. Global rekeying works by advertising the
new keys to wireless clients.
When you select WPA authentication type, a window for Radius setting will
display as followed. Please note IP configure shall be set as fixed IP address
and DHCP mode as “disabled” when WPA authentication type is selected.

ꢀ 64 (40) Bits / 128 (104) Bits
There are two levels of encryption 64 bits and 128 bits. The 64 bits
encryption is referenced as a lower level encryption. The 128 bits encryption
is referenced as a higher level encryption.
The 64 bits WEP encryptions use 40 bits as a secret key, which can
controlled by user, and 24 bits as the initialize vector. These two portions
plus together is 64 bits encryption. Some other vendor’s product might refer
as 40 bits encryption. It is the same thing.
The 128 bits encryption uses 104 bits as a secret key, which can be
controlled by user, and 24 bits as the initial vector.

GN-A11G Wireless LAN Access Point
Wireless Basic Settings
The AP will automatically detect your wireless setting. Basically, no more
modification is required. Changes on these setting will influence your wireless
configuration.
ꢀ SSID
ESSID or SSID means AP names in the wireless network. You should set
the same ESSID of all APs for dynamic clients to roam among APs. The
SSID is up to 32 ASCII characters in length and case sensitive (ie. Letters in
upper case “A~Z” and lower case “a~z” are unique).
ꢀ Channel Number
Please choose the channel for best performance. Normally, no change is
needed. The default value is “Auto” and will be detected automatically by the
system.
ꢀ Wireless Type
Please select your desired wireless type.
ꢀ RTS Threshold
The default value of 2347 shall be retained. In case of inconsist data flow, it
is suggested to make some modifications. Enter a value within the range
0~2347 for the port. RTS (Request To Send) is a function, requesting
permission to transmit signals. RTS is a collision avoidance method used by
all 802.11b wireless networking devices. In most cases you will not need to
activate or administer RTS. Only if you find yourself in an Infrastructure
environment where all nodes are in range of the Access Point but may be
out of range of each other.
ꢀ Preamble Type
Preamble is provided for the receiving end to synchronize necessary
operations. Two settings are available: “Long” or “Short”. The default
value is “Long”. Users can configure in accordance with their needs.

ꢀ Hidden ESSID
This setting enables you to hide ESSID, which is needed by the users to
connect to AP. The default value is “Disable”. All users are able to read AP
names.
ꢀ Associated Clients
Click “Show Active Clients” button to obtain the connecting users’
information.
Wireless Security Setting
We can use this function to set up the security types for AP. Three security types
are available: WEP, WPA and WPA Pre-Shared Key. If you don’t want to set up
security mode, please select “None”.
ꢀ WEP (Wired Equivalent Privacy)
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64/128-bit shared key algorithm. The 64 bits encryption is referenced as a
lower level encryption. The 128 bits encryption is referenced as a higher
level encryption.
ꢀ WPA
If you have used Wi-Fi for a while, you may be familiar with 802.1X
Authentication Protocol, which allows users to authenticate the wireless
network via RASIUS server. 802.1X Authentication Protocol is an option in
standard Wi-Fi but a must for WPA. If a RADIUS server is not avaiable in
your environment, regardless of the needs of 802.1X, you can use WPA. As
another option for RADIUS server, WPA supports pre-shared key.

GN-A11G Wireless LAN Access Point
ꢀ WPA Pre-Shared Key
One of the biggest drawbacks to traditional WEP security is changing the
encryption key. Even you change encrypted keys any time; you still can not
select all APs and wireless LAN adapter while changing encrypted keys.
Instead, rekeying is a tedious manual process and is completely impractical
for large organizations. After all, the instant you rekey an access point, none
of the clients will be able to access it until they are also rekeyed.
But with WPA, the rekeying of global encryption keys is required. In the case
of unicast traffic, the encryption key is changed after every frame using
Temporary Key Integrity Protocol (TKIP). This protocol allows key changes
to occur on a frame-by-frame basis and to be automatically synchronized
between the access point and the wireless client. Global rekeying works by
advertising the new keys to wireless clients.
WDS Settings
The WDS function allows several of the access points to compose a wide
Wireless LAN network. Please note all APs shall be set on the same channel
and the BSSID of APs connected to the network shall be set in the list.
WDS technologies of all AP varies so may not be executed among APs of
different brand names.

Appendix A: Glossary
Access Point
An Access Point is a wired controller that sends data to the wireless NIC’s
installed in your network computers, and received data back from them. An
Access Point is often connected to the network computer that has Internet
access, or is directly connected to an ADSL or cable modem.
ADSL
Asymmetric digital subscriber line (ADSL) is a new modem technology that
converts existing twisted-pair telephone lines into access paths for high-speed
communication of various sorts.
Auto-MDI/MDIX
On a network hub or switch, an auto-MDI/MDIX port automatically senses if it
needs to act as a MDI or MDIX port. The auto- MDI/MDIX capability eliminates
the need for crossover cables.
Auto-negotiate
To automatically determine the correct setting. The term is often used with
communications and networking.
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 assign IP addresses, to deliver TCP/IP stack configuration
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 “Direct Sequence Spread Spectrum,” this is a variety of radio
transmission methods that continuously change frequenciesy or signal patterns.
Direct Sequence Spread Spectrum (DSSS), which is used in CDMA technology,.
multiplied the data bits by a very fast, pseudo-random bet pattern (PN sequence) that “spreads”
the data into a large coded stream that takes the full bandwidth of the channel.

DNS
The Domain Name System (DNS) is a distributed Internet directory service.DNS
is used mostly to translate between domain names and IP addresses, and to
control Internet email delivery. Most Internet services rely on DNS to work, and if
DNS fails, web sites cannot be located and email delivery stalls.
Dynamic IP Address
A IP address is automatically assigned to a user’s AP in a TCP/IP network
typically by a DHCP server.
Firewall
A system designed to prevent unauthorized access to or from a private network.
Firewalls can be implemented in both hardware and software, or a combination
of both.Firewalls are frequently used to prevent unauthorized Internet users from
accessing private networks connected to the Internet, especially intranets.All
messages entering or leaving the intranet pass through the firewall, which
examines each message and blocks those that do not meet the specified
security criteria.
Gateway
A device, usually a Router, that connects hosts on a local network to other
networks.
IP Address
Every PC on the Internet has a fixed identifying number, called a IP Address. A
typical IP 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 fixed hardware number.Usually written as:
01:23:45:67:89:ab
Ping (Packet Internet 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 Internet connections.
Router
A device that forwards data packets along networks. A router is connected to at
least two networks, commonly two LANs or WANs or a LAN and its ISP network.
Routers are located at gateways, the places where two or more networks
connect.

SSID
The SSID is the name represents the routers and Access Point in wireless
network.
Subnet Mask
A mask used to determine which subnet a IP address belongs to. A 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
TCP/IP (Transmission Control Protocol/Internet Protocol), the suite of
communications protocols used to connect hosts on the Internet.
WAN
Wide Area Network, a communication network that covers a relatively broad
geographic area, consisting of two or more LANs. Broadband communication
over the WAN is often through public networks such as the ADSL or Cable
systems, or through leased lines or satellites. To simplify it, please image
network as a WAN.
WEP
WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64/128-bit shared key algorithm, as described in the IEEE 802.11 standard.
