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 TEW-815DAP provides various transmission (data) rate options for you to select. In most
networking scenarios, the factory default Best (automatic) setting proves the most efficient. This
setting allows your TEW-815DAP to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the TEW-815DAP 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 TEW-815DAP 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 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.
10
11
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
12
connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client
devices automatically switches to the channel used in BSS (2).

Introduction
The TEW-815DAP 802.11ac (draft 2.0)3x3 Gigabit Wireless Access Point is an high-performance,
wireless Access Point that supports high-speed wireless networking at home, at work or in
public places.
Unlike most Access Points, the TEW-815DAP provides data transfers at up to 867Mbps when using
11AC connection. This Access Point is also back compatible with 802.11n or 802.11g or 11b
devices. This means that you do not need to change your entire network to maintain connectivity. You
may sacrifice some of 11ac’s speed when you mix 11ac /11n and 11b/g devices, but you will not
lose the ability to communicate when you incorporate the 11ac standard into your 11b/g/n network.
You may choose to slowly change your network by gradually replacing the 11b/g/n devices with 11ac
devices.

Installation Considerations
The TEW-815DAP 802.11ac(draft 2.0)3X3 Gigabit Wireless Access Point 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 TEW-815DAP 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.
15

32
Wireless
Multiple SSID:
You could configure the minimum number of Wireless settings for communication, such as
Network Name (SSID) and Security Mode. The Access Point can be set simply with only the
minimum setting items.
Wireless Network Name (SSID)
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
33
network name. Add up to three additional SSIDs to create virtual wireless networks from one
wireless Access Point Access Point device.
Add Additional Wireless Network Name (SSID)
To add additional wireless Network Names simply add the name to the Multiple SSID field and
click on apply at the bottom of the page. When finished, go to the Security section in this Users
Guide for wireless security configuration.
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.
WPA-
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 "WPA2" option, the Access Point tries WPA2
first, but falls back to WPA if the client only supports WPA. With the "WPA2 Only" option, the
Access Point associates only with clients that also support WPA2 security.
Cipher Type: The encryption algorithm used to secure the data communication. TKIP (Temporal
Key Integrity Protocol) provides per-packet key generation and is based on WEP. AES
(Advanced Encryption Standard) is a very secure block based encryption. With the "TKIP and
AES" option, the Access Point negotiates the cipher type with the client, and uses AES when
available.
Group Key Update Interval: The amount of time before the group key used for broadcast and
multicast data is changed.
WPA-PSK
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.
34
WDS:
This page allows you to configure Wireless Distribution System (WDS) for the wireless LAN
interfaces.
Wireless Distribution System (WDS)
When WDS is enabled, this access point functions as a wireless repeater and is able to
wirelessly communicate with other APs via WDS links. 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.
35
(Note that WDS security is incompatible with mixed mode, like WPAPSK+WPA2PSK mixed,
WEP AUTO and 802.1x, both feature cannot be used at the same time).
Configuring WDS with TEW-815DAP
Enable the option for WDS and input the MAC Address of the wireless device that also supports
WDS in to the blank fields. You can add up to four additional devices in the spaces provided.
Click on apply at the bottom of the page, to apply your setting changes.
Enable the security seeing in security page, each WDS APs need to use same security setting.
(Note: WDS supports wireless g/n modes. The use multiple Access Point will reduces the
overall network throughput to ½ the TEW-815DAP.
36
Advanced:
Use the Advanced Setup page to make detailed settings for the Wireless. Advanced Setup
includes items that are not available from the Basic Setup page, such as Beacon Interval, etc
Beacon Interval
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.
DTIM
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.
37
Fragmentation Threshold
Wireless frames can be divided into smaller units (fragments) to improve performance in the
presence of RF interference and at the limits of RF coverage. Fragmentation will occur when
frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at
its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor
performance.
RTS Threshold
When an excessive number of wireless packet collisions are occurring, wireless performance
can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol.
The wireless transmitter will begin to send RTS frames (and wait for CTS) when data frame size
in bytes is greater than the RTS Threshold. This setting should remain at its default value of
2346 bytes.
Short Preamble and Slot
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.
38
WPS:
Enable
Enable the WPS feature.
PIN Settings
A PIN is a unique number that can be used to add the Access Point to an existing network or to
create a new network. The default PIN may be printed on the bottom of the Access Point. For
extra security, a new PIN can be generated. You can restore the default PIN at any time. Only
the Administrator ("admin" account) can change or reset the PIN.
Current PIN
Shows the current value of the Access Point's PIN.
Reset To WPS Default
Restore the default PIN of the Access Point.
39
Generate New PIN
Create a random number that is a valid PIN. This becomes the Access Point's PIN. You can
then copy this PIN to the user interface of the registrar.
