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-631BRP 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-631BRP to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the TEW-631BRP 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-631BRP 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.

7
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.

8
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 WLAN client
devices automatically switches to the channel used in BSS (2).

Introduction
The TEW-631BRP 11n (Draft) Wireless Router is a high-performance, wireless router that supports
high-speed wireless networking at home, at work or in public places.
Unlike most routers, the TEW-631BRP provides data transfers at up to 300Mbps when using 11n
(Draft) connection. This router is also back compatible with 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
11n’s (Draft) speed when you mix 11n (Draft) and 11b/g devices, but you will not lose the ability to
communicate when you incorporate the 11n (Draft) standard into your 11b/g network. You may
choose to slowly change your network by gradually replacing the 11b/g devices with 11n (Draft)
devices.

Installation Considerations
The TEW-631BRP 11n (Draft) Wireless Router 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-631BRP 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. You will need broadband Internet access (a Cable or DSL-subscriber line into your home or
office)
2. Consult with your Cable or DSL provider for proper installation of the modem.
3. Connect the Cable or DSL modem to the TEW-631BRP Wireless Broadband Router (WAN
port).
4. Ethernet LAN ports of the TEW-631BRP are Auto MDI/MDIX and will work with both
Straight-Through and Cross-Over cable.

Basic_Wireless
The wireless section is used to configure the wireless settings for your router. 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-Enterprise provides a higher
level of security. WPA-Personal does not require an authentication server. The WPA-Enterprise option
does require a RADIUS authentication server.

16
Enable Wireless
This indicates the wireless operating status. The wireless can be turned on or off by the slide
switch at the back panel. When the wireless is enabled, the following parameters are in effect.
Wireless Network Name
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 router automatically finds the channel with least interference and
uses that channel for wireless networking. If you disable this option, the router 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 router 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. Note that when 20/40MHz option is selected, an extended channel will be used
to extend the data rate.
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 (NONE, WEP, WPA-Personal, WPA-Enterprise)
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

17
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 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
router should employ.
WPA Mode: WPA is the older standard; select this option if the clients that will be used with
the router 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 router 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 router associates only with clients that
also support WPA2 security. If the clients support the AES cipher, it 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

18
This option works with a RADIUS Server to authenticate wireless clients. Wireless clients
should have established the necessary credentials before attempting to authenticate to 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.

19
Basic_Network Settings
Use this section to configure the internal network settings of your router. The IP Address that is
configured here is the IP Address that you use to access the Web-based management interface. If you
change the IP Address here, you may need to adjust your PC’s network settings to access the
network again.
