3.2 Basic Setting
This is the page allow you to change the access point.
AP Name: The name of the AP, which can be used to identify the Access Point
among the all the Access Points in the wireless network.
SSID: Service Set Identifier, which is a unique name shared among all clients and
nodes in a wireless network. The SSID must be identical for each clients and nodes in
the wireless network.
Channel: The channel which AP will operate in. You can select the channel range of
1 to 11 for North America (FCC) domain, 1 to 13 for European (ETSI) domain and 1
to 14 for Japanese domain.
Authentication Type: The authentication type default is set to open system.
There are four options: open system; shared key; WPA; WPA-PKS. You may want
to set to Shared Key when the clients and AP in the same wireless network enable the
WEP encryption. All the nodes and hosts on the network must use the same
authentication type. WPA is available but it is required to set 802.1X setting first
before you use WPA.

WEP Key: To disable WEP security, click on the “Disable” option. To enable WEP
security, there are 2 types to select – 64bits and 128 bits. When it is selected, the
key value must be entered in ASCII or HEX format.
Note: When WEP security is enabled, all the wireless clients that wish to connect to
the Access Point must also have WEP enabled with the identical WEP Key value
entered.
Apply: For the changes made to any of the items above to be effective, click “Apply”.
The new settings are now been saved to Access Point and will be effective once the
Access Point restarts.
3.3 IP Setting
This page allows you to configure the IP and DHCP settings of the Access Point.
The default IP address of this access point is 192.168.1.1 with the subnet mask of
255.255.255.0. You can type in other values for IP Address, Subnet Mask and
Gateway and click “Apply” button for the changes to be effective.
You can also set the Access Point to obtain the IP from a DHCP server, but it is not

recommended. Select the option “Obtain IP Automatically” and click “Apply” button
for the changes to be effective.
DHCP Server: It is not recommended to enable the DHCP Server if you have a
DHCP server running in your LAN network because it probably will cause possible
the conflict of IP assignment. Enable the DHCP server function by selecting the
option “On”, and enter the IP range.
Click “Apply” for the changes to be effective.
3.4 Advanced Setting
This page contains configurations for advanced users, which the change reflects the
wireless performance and operating modes.
AP Mode: Select one of the AP operating modes for different application of Access
Point.
1. AP – The normal Access Point operating mode which forms a wireless ESS
network with its wireless clients.
2. AP Client – Acts as an Ethernet-to-Wireless Bridge, which allows a LAN or a
single computer station to join a wireless ESS network through it. You must make
sure SSID and Channel is set the same as that AP you wish to connect.

Remote AP BSS ID: key in the LAN Mac address (NOT wireless Mac address) of
the AP that you wish to get connected. Please note that if you leave Mac address as
000000000000, then you will get connected by the SSID that is set in you AP.
3. Wireless Bridge – A pair of APs operating under Bridge mode to act as the bridge
that connect two Ethernet networks or Ethernet enabled clients together. You must
make sure that the SSID and Channel is set the same as that AP you wish to connect.
Remote Bridge MAC filed: key in the LAN Mac address (NOT wireless Mac
address) of the AP that you wish to get connected.
4. Multiple Bridge – A group of APs which consists of two or more APs operating
under Multiple Bridge mode, that can connect two or more Ethernet networks or
Ethernet enabled clients together.
Note: All APs have to use the same Channel and SSID in order to set a Multiple
Bridge network.
Beacon Interval: To set the period of time in milliseconds that AP sends out a
beacon. Default is 100 milliseconds.
RTS Threshold: To set the size of RTS/CTS packet size. Default is 2432 bytes.
Fragmentation Threshold: To set the number of bytes used for the fragmentation
boundary for directed messages. Default is 2436 bytes.
DTIM Interval: This value indicates the interval of the Delivery Traffic Indication
Message (DTIM). A DTIM field is a countdown field informing clients of the next
window for listening to broadcast and multicast messages. When the access point
has buffered broadcast or multicast messages for associated clients, it sends the next
DTIM with a DTIM interval value. Access point clients hear the beacons and awaken
to receive the broadcast and multicast messages.
SSID Broadcast: While SSID Broadcast is enabled, all wireless clients will be able to
communicate with the access point. For secure purpose, you may want to disable
SSID broadcast to allow only those wireless clients with the AP SSID to
communicate with the access point.

3.5 Security
This page is where you configure the security features supported by this Access Point.
Password: Allow you to change the new login password. Here are the necessary
steps:
1. Enter the new password in the “AP Password New:” field.
2. Enter the new password again in the “Confirm” field.
3. Click “Apply”
MAC Filter: MAC Filter function controls the MAC of the network devices that are
listed in this table for access authorization or denial. When MAC Filter is enabled,
by selecting the “Enabled” radio box, select one of two choices:
●Only deny PCs with MAC listed below to access device
●Only allow PCs with MAC listed below to access device
The maximum number of MAC addresses that can be stored is 50. You can browse
through the MAC address saved by selecting the drop-down box.
For any changes made in the security page, click “Apply” for the changes to be
effective.

3.6 802.1x
There are three essential components to the 802.1x infrastructure: (1) Supplicant, (2)
Authenticator and (3) Server. The Access Point serves as an Authenticator, and the
EAP methods used must be supported by the backend Radius Server. The 802.1x
security supports MD5 and TLS Extensive Authentication Protocol (EAP). Please
follow the steps below to configure 802.1x security.
1. Enable 802.1x security by selecting “Enable”.
2. If MD5 EAP method is used then you can skip step 2 and go to step 3.
3. Select the Encryption Key Length Size ranging from 64 to 128 Bits that you
would like to use. Select the Lifetime of the Encryption Key from 5 Minutes to 1
Day. As soon as the lifetime of the Encryption Key is over, the Encryption Key will
be renewed by the Radius server.

4. Glossary
Access Point: An internetworking device that seamlessly connects wired and
wireless networks.
Ad-Hoc: An independent wireless LAN network formed by a group of computers,
each with a network adapter.
AP Client: One of the additional AP operating modes offered by 54Mbps Access
Point, which allows the Access Point to act as an Ethernet-to-Wireless Bridge, thus a
LAN or a single computer station can join a wireless ESS network through it.
ASCII: American Standard Code for Information Interchange, ASCII, is one of the
two formats that you can use for entering the values for WEP key. It represents
English letters as numbers from 0 to 127.
Authentication Type: Indication of an authentication algorithm which can be
supported by the Access Point:
1. Open System: Open System authentication is the simplest of the available
authentication algorithms. Essentially it is a null authentication algorithm. Any station
that requests authentication with this algorithm may become authenticated if 802.11
Authentication Type at the recipient station is set to Open System authentication.
2. Shared Key: Shared Key authentication supports authentication of stations as either
a member of those who knows a shared secret key or a member of those who does
not.
Backbone: The core infrastructure of a network, which transports information from
one central location to another where the information is unloaded into a local system.
Bandwidth: The transmission capacity of a device, which is calculated by how
much data the device can transmit in a fixed amount of time expressed in bits per
second (bps).
Beacon: A beacon is a packet broadcast by the Access Point to keep the network
synchronized. Included in a beacon are information such as wireless LAN service area,
the AP address, the Broadcast destination addresses, time stamp, Delivery Traffic

Indicator Maps, and the Traffic Indicator Message (TIM).
Bit: A binary digit, which is either -0 or -1 for value, is the smallest unit for data.
Bridge: An internetworking function that incorporates the lowest 2 layers of the OSI
network protocol model.
Browser: An application program that enables one to read the content and
interact in the World Wide Web or Intranet.
BSS: BSS stands for “Basic Service Set”. It is an Access Point and all the LAN PCs
that associated with it.
Channel: The bandwidth which wireless Radio operates is divided into several
segments, which we call them “Channels”. AP and the client stations that it associated
work in one of the channels.
CSMA/CA: In local area networking, this is the CSMA technique that combines
slotted time -division multiplexing with carrier sense multiple access/collision
detection (CSMA/CD) to avoid having collisions occur a second time. This works
best if the time allocated is short compared to packet length and if the number of
situations is small.
CSMA/CD: Carrier Sense Multiple Access/Collision Detection, which is a LAN
access method used in Ethernet. When a device wants to gain access to the network, it
checks to see if the network is quiet (senses the carrier). If it is not, it waits a random
amount of time before retrying. If the network is quiet and two devices access the line
at exactly the same time, their signals collide. When the collision is detected, they
both back off and wait a random amount of time before retrying.
DHCP: Dynamic Host Configuration Protocol, which is a protocol that lets network
administrators manage and allocate Internet Protocol (IP) addresses in a network.
Every computer has to have an IP address in order to communicate with each other in
a TCP/IP based infrastructure network. Without DHCP, each computer must be
entered in manually the IP address. DHCP enables the network administrators to
assign the IP from a central location and each computer receives an IP address upon
plugged with the Ethernet cable everywhere on the network.
DSSS: Direct Sequence Spread Spectrum. 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.
Dynamic IP Address: An IP address that is assigned automatically to a client
station in a TCP/IP network by a DHCP server.
