Chapter 1: Initial Configuration
The Access Point offers a user-friendly web-based management interface for the
configuration of all the unit’s features. Any PC directly attached to the unit can
access the management interface using a web browser, such as Internet Explorer
(version 5.0 or above).
The initial configuration steps can be made through the web browser interface using
the Setup Wizard. It is recommended to make the initial changes by connecting a
PC directly to the access point before installing it in its intended location. The access
point has a default IP address of 192.168.1.20 and a subnet mask of 255.255.255.0.
If your PC has an IP address on the same subnet (that is, the PC and access point
addresses both start 192.168.1.x), you can connect immediately to the web
interface. Otherwise, you must first change your PC’s IP address to be on the same
subnet as the access point.
Logging into the Web Interface
In the web browser’s address bar, type the default IP address: http://192.168.1.20.
The web browser displays the access point’s login page.
The User ID is fixed as “admin.” There is no default password, so just leave the
Password box blank and click LOGIN.
Note: It is strongly recommended that you configure a password. If a password is not
configured, the management interface is not protected and anyone that can
connect to the access point may be able to compromise your network security.
For information on configuring a password, see “Administration” on page 2-7.

Initial Configuration
The home page displays the Main Menu. There are two options available, you can
configure the basic features of the access point using the Setup Wizard’s simple
steps, or you can configure all features in detail using the Advanced Setup menu.
Figure 1-2. Home Page
Using the Setup Wizard
There are only a few basic steps you need to set up the access point and provide a
connection for your Wi-Fi phone and network access for other wireless stations.
The Setup Wizard takes you through configuration procedures for the general
network settings, such as IP configuration, wireless network name (Service Set
Identifier), and wireless security. Follow these steps:
1.

2.
Operation Mode Setting – Select an operation mode according to how your
divice will function.
Figure 1-3. Setup Wizard - Network Setting (AP)
There are three operation modes:
• AP — Set the device as an Access Point.
• Repeater — Set the device as a Wireless Repeater to relay messages
between subnetworks that use different protocols or cable types. The Root
AP MAC Address can be assigned manually or selected after click “Scan”.

Network Setting – Sets the access point’s IP address assignment method and
configures the local Dynamic Host Configuration Prototcol (DHCP) server and
Network Address Translation (NAT) settings.
Figure 1-6. Setup Wizard - Network Setting
There are three basic methods for configuring the access point’s IP address:
• Dynamic IP — The IP address is assigned automatically from a home
gateway router or other device that has a DHCP server feature.
• PPPoE — The IP address is assigned automatically from an Internet service
provider (ISP) through an ADSL modem using Point-to-Point Protocol over
Ethernet (PPPoE). If your ISP has provided you with a user name and
password, enter these in the corresponding text boxes under PPPoE Setting.
• Static IP — The IP address is assigned manually by the user. This may be
required if your access point is connected to a home gateway router or other
device that does not support a DHCP server.
If you select Static IP, enter an appropriate IP address and subnet mask that are
compatible with your existing network. If a management station exists on
another network segment, then you must enter the IP address for a Default
Gateway that can route traffic between these segments. Also enter the IP
address for the Domain Name Server (DNS) to be used for host-name to IP
address resolution.

Initial Configuration
Figure 1-7. Setup Wizard - DHCP Server and NAT Settings
DHCP Server/NAT Setting — This access point includes a DHCP server that
can assign IP addresses to any wireless station or Wi-Fi phone requesting the
service. Addresses are assigned from a common address pool configured on
the access point. You can configure the address pool by specifying start and
end IP addresses.
NAT is a standard method of mapping multiple “internal” IP addresses to one
“external” IP address on devices at the edge of a network. For the access point,
the internal (local) IP addresses are the IP addresses assigned to wireless
clients by the DHCP server, and the external IP address is the IP address
assigned to the access point itself. Note that the access point IP address is
always in a different subnet from the DHCP server pool. The access point uses
the NAT IP settings to route traffic from the wireless interface to the Ethernet
network.

recommended to restrict one VAP network for only Wi-Fi phones and let all
other wireless stations use the other VAP network.
Figure 1-8. Setup Wizard - Setting the VAP#1 SSID and Security
Enter the SSID, or wireless network name, which all wireless stations must use
to associate with the access point. The SSID is case sensitive and can consist
of up to 32 alphanumeric characters (Default: Skype Zones).
The access point offers two wireless security options; Wired Equivalent Privacy
(WEP) or Wi-Fi Protected Access Pre-shared Key (WPA-PSK). Select the
security you want to use and enter the appropriate encryption key, or select
“none” for no security.
• WEP Key — Enter 10 hexadecimal digits (0 to 9 and A to F) or 5
alphanumeric characters for 64 bit keys, 26 hexadecimal digits or 13
alphanumeric characters for 128 bit keys, and 32 hexadecimal digits or 16
alphanumeric characters for 152 bit keys.
• WPA-PSK Key — Enter as an easy-to-remember form of letters and
numbers. The key must be from 8 to 63 characters, which can include
spaces.
Note: All wireless devices must be configured with the same WEP or WPA-PSK Key
values to communicate with the access point.

System Configuration
Wireless VAP Settings
The Wireless VAP #1 Setting and Wireless VAP #2 Setting pages include
configuration options for radio signal characteristics and wireless security features
on the access point.
The following sections apply to both Wireless VAP #1 Setting and Wireless VAP #2
Setting pages.
Note: it is recommended to restrict one VAP network for only Wi-Fi phones and let all
other wireless stations use the other VAP network.
Basic
The Basic Setting page allows you to enable the VAP radio interface and define the
Service Set IDentifier (SSID).
The access point includes an IEEE 802.11g radio for wireless communications. The
IEEE 802.11g standard operates within the 2.4 GHz band at up to 54 Mbps. Note
that because the IEEE 802.11g standard is an extension of the IEEE 802.11b
standard, it allows clients with 802.11b wireless network cards to associate to an
802.11g access point.
The SSID is a recognizable text string that identifies the wireless network service
provided by the VAP interface. Wireless clients that want to connect to the network
must set their SSIDs to match that of the VAP interface.
Figure 2-9. Basic Wireless Settings
The displayed items on this page can be described as follows:
• Radio Status – Enables radio communications for the VAP interface.
(Default: Enabled)
• SSID – The name of the wireless network service provided by the VAP. Clients that
want to connect to the network must set their SSID to the same as that of the VAP
interface. (Defaults: Skype Zones,” VAP #2 “Wireless Network - 1”; Range: 1-32
characters)
2-10
2
Wireless VAP Settings
Channel Setting
The access point uses one radio channel in the 2.4 GHz band to communicate with its
clients. The radio channel may be set manually by the user or automatically by the
system, which selects the channel with the least radio interference.
Note: If you experience poor performance, you may be encountering interference from
another wireless device. Try changing the channel, as this may eliminate
interference and increase performance. Channels 1, 6, and 11, as the three
non-overlapping channels in the 2.4 GHz band, are preferred.
Figure 2-10. Wireless Channel Setting
The displayed items on this page can be described as follows:
• Auto Channel Selection – Enables the access point to automatically select an
interference-free radio channel. (Default: Disabled)
• Radio Channel – The radio channel that the access point uses to communicate
with wireless clients. When multiple access points are deployed in the same area,
set the channel on neighboring access points at least five channels apart to avoid
interference with each other. For example, you can deploy up to three access
points in the same area using channels 1, 6, 11. Note that wireless clients
automatically set the channel to the same as that used by the access point to which
it is linked. (Range: 1-11; Default: 6)
WEP Security
The access point is configured by default as an “open system,” which broadcasts a
beacon signal including the configured SSID. Wireless clients with a configured
SSID of “any” can read the SSID from the beacon and automatically set their SSID
to allow immediate connection to the access point. To secure the wireless network,
you have to implement user authentication and wireless data encryption.
Wired Equivalent Privacy (WEP) provides a basic level of security, preventing
unauthorized access to the network and encrypting data transmitted between
wireless clients and the access point. WEP uses static shared keys (fixed-length
hexadecimal or alphanumeric strings) that are manually distributed to all clients that
want to use the network.
2-11
2
System Configuration
Figure 2-11. WEP Wireless Security
The displayed items on this page can be described as follows:
• WEP Status – Enables the access point to use WEP shared keys. If enabled, you
must configure at least one key for the VAP interface and all its clients.
• Key Type – Select the preferred method of entering WEP encryption keys on the
access point.
- Hexadecimal: Enter keys as hexadecimal digits (0 to 9 and A to F).
- Alphanumeric: Enter keys as alphanumeric characters.
• Setting Key – Sets WEP key values for one or two keys. At least one key must be
specified. Each WEP key has an index number. Index numbers 1 and 2 apply to
VAP #1 interface and numbers 3 and 4 apply to VAP #2 interface. The selected key
is used for authentication and encryption on the VAP interface.
Enter key values that match the key type and length settings. Select 64 Bit, 128 Bit,
or 152 Bit key length. Note that the same size of encryption key must be supported
on all wireless clients. (Default: 64 Bit)
- 64 Bit: Enter keys as 5 alphanumeric characters or 10 hexadecimal digits.
- 128 Bit: Enter keys as 13 alphanumeric characters or 26 hexadecimal digits.
- 152 Bit: Enter keys as 16 alphanumeric characters or 32 hexadecimal digits.
Note: Key index and type must match that configured on all clients.
WPA-PSK Security
Wi-Fi Protected Access (WPA) employs a combination of technologies to provide an
enhanced security solution for wireless networks. The WPA Pre-shared Key
(WPA-PSK) mode for small networks uses a common password phrase that must be
manually distributed to all clients that want to connect to the network.
WPA2 is a futher security enhancement that includes the now ratified IEEE 802.11i
wireless security standard. Both WPA and WPA2 provide very robust security
through the support of the Advanced Encryption Standard (AES) and Temporal Key
Integrity Protocol (TKIP) encryption ciphers.
2-12
2
Wireless VAP Settings
Note: The computationally intensive operations of AES encryption requires hardware
support on client devices. Before implementing AES in the network, be sure that
wireless client hardware is AES or WPA2 compliant.
Figure 2-12. WPA-PSK Wireless Security
The displayed items on this page can be described as follows:
• WPA-PSK Status – Enables WPA-PSK or WPA2-PSK security on the VAP
interface. When enabled, WEP clients are not supported. (Default: Enabled).
• Authentication – Selects WPA-PSK or WPA2-PSK security.
• Key Cipher Mode – Selects the encryption cipher to use for multicast and unicast
data traffic:
- Auto – Uses TKIP for the multicast cipher and TKIP or AES for the unicast cipher
depending on the capability of associated clients.
- AES – Uses AES keys for both multicast and unicast encryption.
- TKIP – Uses TKIP keys for both multicast and unicast encryption.
• WPA-PSK Key – Enter a key as an easy-to-remember form of letters and
numbers. The key must be from 8 to 63 characters, which can include spaces. All
wireless clients must be configured with the same key to communicate with the
VAP interface.

System Configuration
Network Settings
The access point supports DHCP client, DHCP server and Network Address
Translation (NAT). Point-to-Point Protocol over Ethernet (PPPoE) is also supported
for users that have an IP address assigned automatically from an Internet service
provider (ISP) through an ADSL modem.
DHCP Client
Configuring the access point with an IP address enables you to manage the access
point from any PC in the attached network. A number of access point features
depend on IP addressing to operate.
Note: You can connect to the web browser interface to access IP addressing only if the
access point already has an IP address that is reachable through your network.
By default, the access point is configured with the IP address 192.168.1.20, with the
DHCP client disabled.
Figure 2-13. DHCP Client Settings
The displayed items on this page can be described as follows:
• DHCP Client Setting – Enables the access point to automatically obtain an IP
address from a DHCP server. If a response is not received from the DHCP server,
the access point uses the fixed IP settings as configured on this page. When set to
disabled, a static IP address can be manually configured.
• Static IP Address – The IP address of the access point. Valid IP addresses
consist of four decimal numbers, 0 to 255, separated by periods.
2-14
2
Network Settings
• Subnet Mask – The mask that identifies the host address bits used for routing to
specific subnets.
• Default Gateway – The default gateway is the IP address of the router for the
access point, which is used if the requested destination address is not on the local
subnet. If you have management stations located on another subnet, type the IP
address of the default gateway router in the text field provided. Otherwise, leave
the address as all zeros (0.0.0.0).
• DNS IP Address – The IP address of a Domain Name Server on the network. A
DNS maps numerical IP addresses to domain names and can be used to identify
network hosts by familiar names instead of the IP addresses.
If you have a DNS server located on the local network, type the IP address in the
text field provided. Otherwise, leave the address as all zeros (0.0.0.0).
DHCP Server/NAT
The access point includes a Dynamic Host Configuration Protocol (DHCP) server
that can assign temporary IP addresses to wireless clients requesting the service.
Addresses are assigned to clients from a common address pool configured on the
access point. Configure an address pool by specifying start and end IP addresses.
Be sure not to include the access point's IP address in the address pool range.
Network Address Translation (NAT) is a standard method of mapping multiple
"internal" IP addresses to one "external" IP address on devices at the edge of a
network. For the access point, the internal (local) IP addresses are the IP addresses
assigned to wireless clients by the DHCP server, and the external IP address is the
IP address assigned to the Ethernet port. When enabled, the access point's wireless
interface uses the NAT IP settings to access the Ethernet network.
Note: When the DHCP server is enabled, NAT is also enabled.

PPPoE
Many Internet service providers (ISPs) use the Point-to-Point Protocol over Ethernet
(PPPoE) to automatically assign an IP address to users with a DSL modem. The
PPPoE page provides the settings needed for this service.
Figure 2-15. PPPoE Settings
The displayed items on this page can be described as follows:
• PPPoE Setting — Enables the access point IP address to be assigned
automatically from an Internet service provider (ISP) through an ADSL modem
using PPPoE.

System Configuration
Time and Log
Simple Network Time Protocol (SNTP) allows the access point to set its internal
clock based on periodic updates from a time server (SNTP or NTP). Maintaining an
accurate time on the access point enables all system log messages to be stamped
with the correct time and date. If the clock is not set, the access point only records
the time from the factory default set at the last bootup.
The access point acts as an SNTP client, which periodically sends time
synchronization requests to a specific time server. SNTP uses Coordinated
Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the
time at the Earth’s prime meridian, zero degrees longitude. To display the time
corresponding to your local time, you must also indicate the number of hours your
time zone is located before or after UTC/GMT.
Figure 2-16. SNTP Settings
The displayed items on this page can be described as follows:
• SNTP Server Setting — Configures the access point to operate as an SNTP client.
When enabled, the time server IP address must be specified.
• Primary Server: The IP address of an SNTP or NTP time server that the access
point attempts to poll for a time update.
• Time Zone — Sets the number of hours your local time zone is located before or
after UTC/GMT. (Default: GMT+00)

Time and Log
• Daylight Saving — The access point provides a way to automatically adjust the
system clock for Daylight Savings Time changes. To use this feature you must
define the month and date to begin and to end the change from standard time.
During this period the system clock is set back by one hour.

• Set the access point to its default configuration by pressing the reset button
on the back panel for 5 seconds or more. Connect to the web management
interface using the default IP address 192.168.1.20. Then use the default user
name “admin” and a null password to access the management interface.
4.
If all other recovery measure fail, and the access point is still not functioning
properly, take any of these steps:
• Reset the access point’s hardware using the web interface or through a power
reset.
• Reset the access point to its default configuration by pressing the reset button
on the back panel for 5 seconds or more. Connect to the web management

HARDWARE INSTALLATION
Ethernet Port
To install the Access Point, follow these steps:
The access point has one 10BASE-T/100BASE-TX RJ-45 port that can be
attached directly to 10BASE-T/100BASE-TX LAN segments. These
segments must conform to the IEEE 802.3-2005 specifications.
This port supports automatic MDI/MDI-X operation, so you can use
straight-through cables for all network connections to PCs, switches, or
hubs.
1.
Select a Site – Choose a proper place for the access point. In
general, the best location is at the center of your wireless coverage
area, within line of sight of all wireless devices. For optimum
performance, consider these points:
• Mount the access point as high as possible above any obstructions
in the coverage area.
Reset Button
• Avoid mounting next to or near building support columns or other
obstructions that may cause reduced signal or null zones in parts of
the coverage area.
The Reset button is used to restart the access point or restore the factory
default configuration. If you hold down the button for less than 5 seconds,
the access point will perform a hardware reset. If you hold down the
button for 5 seconds or more, any configuration changes you may have
made are removed, and the factory default configuration is restored to the
access point.
• Mount away from any signal absorbing or reflecting structures (such
as those containing metal).
• Avoid radio interference by mounting away from other 2.4 GHz
devices, such as other 802.11b or g wireless devices, regular
cordless phones, and microwave ovens.
