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.
T
HE 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-672GR 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-672GR to operate at the maximum transmission (data) rate. When the communication quality drops
below a certain level, the TEW-672GR 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-672GR 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 infrastructure
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.
A
D-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).
6
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).

Installation Considerations
The TEW-672GR 2.4/5GHz Dual-Band Wireless 802.11n(DRAFT) Giga 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-672GR 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-672GR Wireless Broadband Router (WAN port).
4. Ethernet LAN ports of the TEW-672GR are Auto MDI/MDIX and will work with both
Straight-Through and Cross-Over cable.

Network
Network: WAN Setting
WAN Connection Type
There are several connection types to choose from: Static IP, DHCP, PPPoE, PPTP, L2TP, and Russia
PPTP. If you are unsure of your connection method, please contact your Internet Service Provider.
Static
Used when your ISP provides you a set IP address that does not change. The IP information is manually
entered in your IP configuration settings. You must enter the IP address, Subnet Mask, Gateway, Primary
DNS Server, and Secondary DNS Server. Your ISP provides you with all of this information.
DHCP
A method of connection where the ISP assigns your IP address when your router requests one from the
ISP's server.
Host Name: Some ISP's may check your computer's Host Name. The Host Name identifies your system
to the ISP's server.
PPPoE
Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet)
connection. DSL providers typically use this option. This method of connection requires you to enter a
Username and Password (provided by your Internet Service Provider) to gain access to the Internet.
Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to set the
reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
17
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the Web-based management interface and click the Connect button
manually any time that you wish to connect to the Internet.
Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual" reconnect
modes.
L2TP
L2TP (Layer Two Tunneling Protocol) uses a virtual private network to connect to your ISP. This
method of connection requires you to enter a Username and Password (provided by your Internet
Service Provider) to gain access to the Internet.
L2TP Server IP Address: The ISP provides this parameter, if necessary. The value may be the same as
the Gateway IP Address.
Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to set the
reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the Web-based management interface and click the Connect button
manually any time that you wish to connect to the Internet.
Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual" reconnect
modes.
WAN Interface IP Type
Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for the
following fields for WAN Interface IP Setting:
IP Address, Subnet Mask , Default Gateway.
Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this
option.
PPTP
PPTP (Point to Point Tunneling Protocol) uses a virtual private network to connect to your ISP. This
method of connection is primarily used in Europe. This method of connection requires you to enter a
Username and Password (provided by your Internet Service Provider) to gain access to the Internet.
PPTP Server IP Address: The ISP provides this parameter, if necessary. The value may be the same as
the Gateway IP Address.
Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to set the
reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the Web-based management interface and click the Connect button
manually any time that you wish to connect to the Internet.
Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
18
disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual" reconnect
modes.
WAN Interface IP Type
Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for the
following fields for WAN Interface IP Setting:
IP Address, Subnet Mask , Default Gateway, and optional for DNS Server
Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this
option.
Russia PPTP
The Russia PPTP can
configure IP address on the WAN interface and establish PPTP to get IP
address, subnet mask, default gateway and DNS for ANOTHER logical IP interface on WAN port.
So the physical WAN port will have 2 logical IP interfaces and can communicate with internal
ISP’s network resources and also communicate with Internet through PPTP tunnel. It is specified
by Russia Cobrina ISP, user can configure it the same as the normal PPTP and PPTP
server IP Address can use the domain name string.
WAN MTU Setting
The Maximum Transmission Unit (MTU) is a parameter that determines the largest packet size (in
bytes) that the router will send to the WAN. If LAN devices send larger packets, the router will
break them into smaller packets. Ideally, you should set this to match the MTU of the connection to
your ISP. Typical values are 1500 bytes for an Ethernet connection and 1492 bytes for a PPPoE
connection. If the router's MTU is set too high, packets will be fragmented downstream. If the
router's MTU is set too low, the router will fragment packets unnecessarily and in extreme cases
may be unable to establish some connections. In either case, network performance can suffer. t
modes.
MAC Address Clone
Each networking device has it's own unique MAC address defined by the hardware manufacturer.
Some ISP's may check your computer's MAC address. Some ISP's record the MAC address of the
network adapter in the computer or router used to initially connect to their service. The ISP will
then only grant Internet access to requests from a computer or router with this particular MAC
address. This router has a different MAC address than the computer or router that initially
connected to the ISP. If you need to change the MAC address of the rounter's WAN-side Ethernet
interface, either type in an alternate MAC address (for example, the MAC address of the router
initially connected to the ISP) or copy the MAC address of a PC. To copy the MAC address of the
computer that initially connected to the ISP, connect to the router using that computer and click the
Clone Your PC's MAC Address button. The WAN interface will then use the MAC address of the
network adapter in your computer.
