Wireless LAN Networking
This section provides background information on wireless LAN networking technology.
Consult the “Glossary” for definitions of the terminology used in this section.
THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING
NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD
ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR.
Transmission Rate (Transfer Rate)
The WAP-372U provides various transmission (data) rate options for you to select. In most
networking scenarios, the factory default Best (Auto) setting proves the most efficient. This
setting allows your WAP-372U to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the WAP-372U automatically switches to a
lower transmission (data) rate. Transmission at lower data speeds is usually more reliable.
However, when the communication quality improves again, the WAP-372U gradually increases
the transmission (data) rate again until it reaches the highest available transmission rate.
Types of Wireless Networks
Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infra-
structure mode, wireless devices communicate to a wired LAN via access points. Each access
point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set
(ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer
mode), wireless devices communicate with each other directly and do not use an access point.
This is an Independent BSS (IBSS).
To connect to a wired network within a coverage area using access points, set the WAP-372U
operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an
access point, use Ad-hoc (IBSS) mode.
AD-HOC (IBSS) NETWORK
Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations
communicate directly to each other. An ad-hoc network may sometimes be referred to as an
Independent Basic Service Set (IBSS).
To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID
and channel for each station.
8
9
When a number of wireless stations are connected using a single access point, you have a
Basic Service Set (BSS).
In the ESS diagram below, communication is done through the access points, which relay data
packets to other wireless stations or devices connected to the wired network. Wireless stations
can then access resources, such as a printer, on the wired network.
In an ESS environment, users are able to move from one access point to another without losing
the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the
WAP-372U automatically switches to the channel used in BSS (2).

Introduction
The WAP-372U is an 802.11n (draft) high-performance, wireless AP that supports high-speed
wireless networking at home, at work or in public places.
Unlike most APs, the WAP-372U provides data transfers at up to 300 Mbps when used with other
11n (draft) products. This AP is backwards compatible with 802.11b/g products. This means that
you do not need to change your entire network to maintain connectivity. You may sacrifice some of
802.11g’s speed when you mix 802.11n (draft) and 802.11g devices, but you will not lose the
ability to communicate when you incorporate the 802.11n (draft) into your 802.11g network. You
may choose to slowly change your network by gradually replacing the 802.11g devices with
802.11n (draft) devices.
Features
Ø Supports IEEE 802.11n (draft) & 11b/g 2.4GHz wireless Local Area Network (WLAN)

Installation Considerations
Page 14
The WAP-372U AP lets you access your network, using a wireless connection, from virtually
anywhere within its operating range. Keep in mind, however, that the number, thickness and
location of walls, ceilings, or other objects that the wireless signals must pass through, may limit
the range. Typical ranges vary depending on the types of materials and background RF (radio
frequency) noise in your home or business. The key to maximizing wireless range is to follow these
basic guidelines:
1 Keep the number of walls and ceilings between the WAP-372U and other network devices
to a minimum - each wall or ceiling can reduce your wireless product’s range from 3-90
feet (1-30 meters.) Position your devices so that the number of walls or ceilings is
minimized.
2 Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters),
at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it
looks over 42 feet (14 meters) thick! Position devices so that the signal will travel straight
through a wall or ceiling (instead of at an angle) for better reception.
3 Building Materials can impede the wireless signal - a solid metal door or aluminum studs
may have a negative effect on range. Try to position wireless devices and computers with
wireless adapters so that the signal passes through drywall or open doorways and not other
materials.
4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate extreme RF noise.
Getting Started
For a typical wireless setup at home, please do the following:
1. Plug the power adapter to outlay, and connect the power jack to the WAP-372U.

Basic_Wireless
Page 17
The wireless section is used to configure the wireless settings for your Access Point. Note that
changes made in this section may also need to be duplicated on wireless clients that you want to
connect to your wireless network.
To protect your privacy, use the wireless security mode to configure the wireless security features.
This device supports three wireless security modes including: WEP, WPA-Personal, and
WPA-Enterprise. WEP is the original wireless encryption standard. WPA provides a higher level of
security. WPA-Personal does not require an authentication server. The WPA-Enterprise option does
require a RADIUS authentication server.
Wireless Radio
This status indication shows you the wireless radio is on or off.
Wireless Network Name
Page 18
When you are browsing for available wireless networks, this is the name that will appear
in the list (unless Visibility Status is set to Invisible, see below). This name is also referred
to as the SSID. For security purposes, it is highly recommended to change from the
pre-configured network name.
Enable Auto Channel Scan
If you select this option, the Access Point automatically finds the channel with least
interference and uses that channel for wireless networking. If you disable this option, the
Access Point uses the channel that you specify with the following Wireless Channel
option.
Wireless Channel
A wireless network uses specific channels in the wireless spectrum to handle
communication between clients. Some channels in your area may have interference from
other electronic devices. Choose the clearest channel to help optimize the performance
and coverage of your wireless network.
802.11 Mode
If all of the wireless devices you want to connect with this Access Point can connect in the
same transmission mode, you can improve performance slightly by choosing the
appropriate "Only" mode. If you have some devices that use a different transmission
mode, choose the appropriate "Mixed" mode.
Channel Width
The "Auto 20/40 MHz" option is usually best. The other options are available for special
circumstances.
Transmission Rate
By default the fastest possible transmission rate will be selected. You have the option of
selecting the speed if necessary.
Visibility Status
The Invisible option allows you to hide your wireless network. When this option is set to
Visible, your wireless network name is broadcast to anyone within the range of your signal.
If you're not using encryption then they could connect to your network. When Invisible
mode is enabled, you must enter the Wireless Network Name (SSID) on the client
manually to connect to the network.
Security Mode
Unless one of these encryption modes is selected, wireless transmissions to and from your
wireless network can be easily intercepted and interpreted by unauthorized users.
WEP
A method of encrypting data for wireless communication intended to provide the same
level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain
access to a WEP network, you must know the key. The key is a string of characters that
you create. When using WEP, you must determine the level of encryption. The type of
encryption determines the key length. 128-bit encryption requires a longer key than 64-bit
encryption. Keys are defined by entering in a string in HEX (hexadecimal - using
Page 19
characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange -
alphanumeric characters) format. ASCII format is provided so you can enter a string that
is easier to remember. The ASCII string is converted to HEX for use over the network.
Four keys can be defined so that you can change keys easily. A default key is selected for
use on the network.
Example:
64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string
of 10 characters for 64-bit encryption.)
128-bit hexadecimal keys are exactly 26 characters in length.
(456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit encryption.)
64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5 characters
for 64-bit encryption.)
128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of
13 characters for 128-bit encryption.)
Note that, if you enter fewer characters in the WEP key than required, the remainder of
the key is automatically padded with zeros.
WPA-Personal and WPA-Enterprise
Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security
standards published by the Wi-Fi Alliance. The WPA Mode further refines the variant that
the Access Point should employ.
WPA Mode: WPA is the older standard; select this option if the clients that will be used
with the Access Point only support the older standard. WPA2 is the newer implementation
of the stronger IEEE 802.11i security standard. With the "WPA or WPA2" option, the
Access Point tries WPA2 first, but falls back to WPA if the client only supports WPA. The
strongest cipher that the client supports will be used. With the "WPA2 Only" option, the
Access Point associates only with clients that also support WPA2 security. The AES cipher
will be used across the wireless network to ensure best security.
Group Key Update Interval: The amount of time before the group key used for
broadcast and multicast data is changed.
WPA-Personal
This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).
Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric
characters in ASCII (American Standard Code for Information Interchange) format at both
ends of the wireless connection. It cannot be shorter than eight characters, although for
proper security it needs to be of ample length and should not be a commonly known
phrase. This phrase is used to generate session keys that are unique for each wireless
client.
Example:
Wireless Networking technology enables ubiquitous communication
WPA-Enterprise
This option works with a RADIUS Server to authenticate wireless clients. Wireless clients
should have established the necessary credentials before attempting to authenticate to
Page 20
the Server through this Gateway. Furthermore, it may be necessary to configure the
RADIUS Server to allow this Gateway to authenticate users.
Authentication Timeout: Amount of time before a client will be required to
re-authenticate.
RADIUS Server IP Address: The IP address of the authentication server.
RADIUS Server Port: The port number used to connect to the authentication server.
RADIUS Server Shared Secret: A pass-phrase that must match with the authentication
server.
MAC Address Authentication: If this is selected, the user must connect from the same
computer whenever logging into the wireless network.
Advanced:
Optional Backup RADIUS Server
This option enables configuration of an optional second RADIUS server. A second RADIUS
server can be used as backup for the primary RADIUS server. The second RADIUS server
is consulted only when the primary server is not available or not responding. The fields
Second RADIUS Server IP Address, RADIUS Server Port, Second RADIUS server
Shared Secret, Second MAC Address Authentication provide the corresponding
parameters for the second RADIUS Server.
Basic_Network Settings
Page 21
Access Point Settings
These are the settings of the LAN (Local Area Network) interface for the Access Point. The
Access Point's local network (LAN) settings are configured based on the IP Address and
Subnet Mask assigned in this section. The IP address is also used to access this Web-based
management interface.
Get LAN IP From
Choose "DHCP (Dynamic)" if your router supports DHCP and you want the router to assign
an IP address to the AP. In this case, you do not need to fill in the following fields. Choose
"Static IP (Manual)" if your router does not support DHCP or if for any other reason you
need to assign a fixed address to the AP. In this case, you must also configure the
following fields.
Note that you cannot choose "DHCP (Dynamic)" if you have enabled the "DHCP Server"
option on the DHCP page; the AP cannot be both a DHCP client and a DHCP server.
Page 22
IP Address
The IP address of the AP on the local area network. Assign any unused IP address in the
range of IP addresses available for the LAN. For example, 192.168.1.100.
Subnet Mask
The subnet mask of the local area network.
Gateway
The IP address of the router on the local area network.
Local Domain Name
This entry is optional. Enter a domain name for the local network. The AP's DHCP server
will give this domain name to the computers on the wireless LAN. So, for example, if you
enter mynetwork.net here, and you have a wireless laptop with a name of chris,
that laptop will be known as chris.mynetwork.net. Note, however, if the AP's
settings specify "DHCP (Dynamic)" Address, and the router's DHCP server assigns a domain
name to the AP, that domain name will override any name you enter here.
DHCP Server Settings
DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you
configure the built-in DHCP Server to assign IP addresses to the computers and other
devices on your local area network (LAN).
Enable DHCP Server
In most situations, the router provides DHCP services, and you can leave this option
disabled. However, if for any reason the router does not provide DHCP services, enable this
option. The AP's DHCP Server will then manage the IP addresses and other network
configuration information for wireless clients associated with the AP.
The computers (and other devices) connected to your LAN also need to have their TCP/IP
configuration set to "DHCP" or "Obtain an IP address automatically".
When you set Enable DHCP Server, the following options are displayed.
DHCP IP Address Range
These two IP values (from and to) define a range of IP addresses that the DHCP Server
uses when assigning addresses to computers and devices on your Local Area Network. Any
addresses that are outside of this range are not managed by the DHCP Server; these could,
therefore, be used for manually configured devices or devices that cannot use DHCP to
obtain network address details automatically.
It is possible for a computer or device that is manually configured to have an address that
does reside within this range. In this case the address should be reserved, so that the
DHCP Server knows that this specific address can only be used by a specific computer or
device.
Your Access Point, by default, has a static IP address of 192.168.1.100. This means that
addresses 192.168.1.101 to 192.168.1.254 can be made available for allocation by the
DHCP Server.
Example:
Page 23
Your Access Point uses 192.168.1.1 for the IP address. You've assigned a computer that
you want to designate as a Web server with a static IP address of 192.168.1.101. You've
assigned another computer that you want to designate as an FTP server with a static IP
address of 192.168.1.102. Therefore the starting IP address for your DHCP IP address
range needs to be 192.168.1.103 or greater.
Example:
Suppose you configure the DHCP Server to manage addresses From 192.168.1.101 To
192.168.1.199. This means that 192.168.1.1 to 192.168.1.99 and 192.168.1.200 to
192.168.1.254 are NOT managed by the DHCP Server. Computers or devices that use
addresses from these ranges are to be manually configured. Suppose you have a web
server computer that has a manually configured address of 192.168.1.101. Because this
falls within the "managed range" be sure to create a reservation for this address and match
it to the relevant computer.
DHCP Lease Time
The amount of time that a computer may have an IP address before it is required to renew
the lease. The lease functions just as a lease on an apartment would. The initial lease
designates the amount of time before the lease expires. If the tenant wishes to retain the
address when the lease is expired then a new lease is established. If the lease expires and
the address is no longer needed than another tenant may use the address.
Always Broadcast
If all the computers on the LAN successfully obtain their IP addresses from the Access
Point's DHCP server as expected, this option can remain disabled. However, if one of the
computers on the LAN fails to obtain an IP address from the Access Point's DHCP server, it
may have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets.
Enabling this option will cause the Access Point to always broadcast its responses to all
clients, thereby working around the problem, at the cost of increased broadcast traffic on
the LAN.
Add/Edit DHCP Reservation
This option lets you reserve IP addresses, and assign the same IP address to the network
device with the specified MAC address any time it requests an IP address. This is almost
the same as when a device has a static IP address except that the device must still request
an IP address from the Access Point. The Access Point will provide the device the same IP
address every time. DHCP Reservations are helpful for server computers on the local
network that are hosting applications such as Web and FTP. Servers on your network
should either use a static IP address or use this option.
Computer Name
You can assign a name for each computer that is given a reserved IP address. This may
help you keep track of which computers are assigned this way. Example: Game Server.
IP Address:
The LAN address that you want to reserve.
MAC Address
To input the MAC address of your system, enter it in manually or connect to the Access
Point's Web-Management interface from the system and click the Copy Your PC's MAC
Address button.
Page 24
A MAC address is usually located on a sticker on the bottom of a network device. The MAC
address is comprised of twelve digits. Each pair of hexadecimal digits are usually separated
by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network
device is a computer and the network card is already located inside the computer, you can
connect to the Access Point from the computer and click the Copy Your PC's MAC
Address button to enter the MAC address.
As an alternative, you can locate a MAC address in a specific operating system by following
the steps below:
Windows 98
Windows Me Go to the Start menu, select Run, type in winipcfg, and hit Enter. A
popup window will be displayed. Select the appropriate adapter from the
pull-down menu and you will see the Adapter Address. This is the MAC
address of the device.
Windows 2000
Windows XP Go to your Start menu, select Programs, select Accessories, and select
Command Prompt. At the command prompt type ipconfig /all
and
hit Enter. The physical address displayed for the adapter connecting to
the Access Point is the MAC address.
Mac OS X Go to the Apple Menu, select System Preferences, select Network, and
select the Ethernet Adapter connecting to the Access Point. Select the
Ethernet button and the Ethernet ID will be listed. This is the same as
the MAC address.
DHCP Reservations List
This shows clients that you have specified to have reserved DHCP addresses. An entry can
be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click
the Edit icon, the item is highlighted, and the "Edit DHCP Reservation" section is activated
for editing.
Number of Dynamic DHCP Clients
In this section you can see what LAN devices are currently leasing IP addresses.
Revoke
The Revoke option is available for the situation in which the lease table becomes full or
nearly full, you need to recover space in the table for new entries, and you know that some
of the currently allocated leases are no longer needed. Clicking Revoke cancels the lease
for a specific LAN device and frees an entry in the lease table. Do this only if the device no
longer needs the leased IP address, because, for example, it has been removed from the
network.
Reserve
The Reserve option converts this dynamic IP allocation into a DHCP Reservation and
adds the corresponding entry to the DHCP Reservations List.
Page 25
Advanced
The Advanced tab provides the following configuration options: MAC Address Filter and
Advanced Network.
Advanced_MAC Address Filter
The MAC address filter section can be used to filter network access by machines based on the
unique MAC addresses of their network adapter(s). It is most useful to prevent unauthorized
wireless devices from connecting to your network. A MAC address is a unique ID assigned by the
manufacturer of the network adapter.
Enable MAC Address Filter
When this is enabled, computers are granted or denied network access depending on the
mode of the filter.
Note: Misconfiguration of this feature can prevent any machine from accessing the
network. In such a situation, you can regain access by activating the factory defaults
button on the Access Point itself.
Filter Settings
Page 26
Mode
When "only allow listed machines" is selected, only computers with MAC addresses listed
in the MAC Address List are granted network access. When "only deny listed machines" is
selected, any computer with a MAC address listed in the MAC Address List is refused
access to the network.
Filter Wireless Clients
When this is selected, the MAC address filters will be applied to wireless network clients.
Filter Wired Clients
When this is selected, the MAC address filters will be applied to wired network clients.
Add/Edit MAC Address
In this section, you can add entries to the MAC Address List below, or edit existing entries.
Enable
MAC address entries can be activated or deactivated with this checkbox.

Page 27
Beacon Period
Beacons are packets sent by a wireless Access Point to synchronize wireless devices.
Specify a Beacon Period value between 20 and 1000. The default value is set to 100
milliseconds.
RTS Threshold
This setting should remain at its default value of 2346. If you encounter inconsistent data
flow, only minor modifications to the value are recommended.
Fragmentation Threshold
This setting should remain at its default value of 2346. Setting the Fragmentation value
too low may result in poor performance.
DTIM Interval
A DTIM is a countdown informing clients of the next window for listening to broadcast and
multicast messages. When the wireless Access Point has buffered broadcast or multicast
messages for associated clients, it sends the next DTIM with a DTIM Interval value.
Wireless clients detect the beacons and awaken to receive the broadcast and multicast
messages. The default value is 1. Valid settings are between 1 and 255.
Page 28
WMM Enable
Enabling WMM can help control latency and jitter when transmitting multimedia content
over a wireless connection.
Short GI
Using a short (400ns) guard interval can increase throughput. However, it can also
increase error rate in some installations, due to increased sensitivity to radio-frequency
reflections. Select the option that works best for your installation.
WDS Enable
When WDS is enabled, this access point functions as a wireless repeater and is able to
wirelessly communicate with other APs via WDS links. Note that WDS is incompatible with
WPA -- both features cannot be used at the same time. A WDS link is bidirectional; so this
AP must know the MAC Address (creates the WDS link) of the other AP, and the other AP
must have a WDS link back to this AP. Make sure the APs are configured with same
channel number.
WDS AP MAC Address
Specifies one-half of the WDS link. The other AP must also have the MAC address of this
AP to create the WDS link back to this AP. Enter a MAC address for each of the other APs
that you want to connect with WDS.

Check this option if your location observes daylight saving time.
Daylight Saving Offset
Select the time offset, if your location observes daylight saving time.
DST Start and DST End
Select the starting and ending times for the change to and from daylight saving time. For
example, suppose for DST Start you select Month="Oct", Week="3rd", Day="Sun" and
Time="2am". This is the same as saying: "Daylight saving starts on the third Sunday of
October at 2:00 AM."
Set the Date and Time Manually
If you do not have the NTP Server option in effect, you can either manually set the time
for your Access Point here, or you can click the Copy Your Computer's Time Settings
button to copy the time from the computer you are using. (Make sure that computer's
time is set correctly.)
Note: If the Access Point loses power for any reason, it cannot keep its clock running, and will not
have the correct time when it is started again. To maintain correct time for schedules and logs,
either you must enter the correct time after you restart the Access Point, or you must enable the
NTP Server option.
