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-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 -H OC (IBSS) N ETWORK
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.
19
Network: LAN Setting
LAN Interface Setting
IP Address
The IP address of the this device on the local area network. Assign any unused IP address in the range of
IP addresses available for the LAN. For example, 192.168.10.101.
Subnet Mask
The subnet mask of the local area network.
20
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
Once your router is properly configured and this option is enabled, the DHCP Server will manage the IP
addresses and other network configuration information for computers and other devices connected to
your Local Area Network. There is no need for you to do this yourself.
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 (Start and End) 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 router, by default, has a static IP address of 192.168.10.1. This means that addresses 192.168.10.2
to 192.168.10.254 can be made available for allocation by the DHCP Server.
Subnet Mask
The subnet mask of the local area network.
Gateway
The IP address of the router on the local area network. For example, 192.168.10.1.
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.
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 router. The router 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.
21
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 router's
Web-Management interface from the system and click the Copy Your PC's MAC Address button.
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 router from the computer and click
the Copy Your PC's MAC Address button to enter the MAC address.

Wireless 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 wireless mode. If you have
some devices that use a different transmission mode, choose the appropriate wireless mode. The
TEW-672GR supports both 2.4GHz and 5GHz wireless networks. There are many different
configuration options available to choose from. Use the drop down list to select the wireless mode.
Note: One wireless mode can be selected can select at any one time. This means that you can only select
one of the operating frequency at a time

Wireless Mode options
2.4GHz 802.11b/g mixed mode - This wireless mode works in the 2.4GHz frequency range
and will allow both wireless b and wireless g client to connect and access the TEW-672GR at
11Mbps for wireless b, at 54Mbps for wireless g and share access at the same time. Although
the wireless b/g operates in the 2.4GHz frequency, it will allow the use of other 2.4GHz client
devices (Wireless n/g @ 54Mbps) to connect and access at the same time.
2.4GHz 802.11 wireless b/g mixed mode
25
2.4GHz 802.11 n only – This wireless mode works in the 2.4GHz frequency range and will
only allow the use of wireless n client devices to connect and access the TEW-672GR up to
300Mbps*. Although the wireless n operates in the 2.4GHz frequency, this mode will only
permit wireless n client devices to work and will exclude any other wireless mode and devices
that are not wireless n only.
2.4GHZ 802.11 wireless n only
5GHz 802.11a/n mixed mode - This wireless mode works in the 5GHz frequency range and
will only allow the use of wireless a/n dual band client devices to connect and access the
TEW-672GR up to 300Mbps*. Dual band wireless client devices that support both wireless a/n
can connect and access the TEW-672GR up to 300Mbps. Wireless a client devices can connect
and access the TEW-672GR but, will only connect up to 54Mbps, (this due to the legacy
limitation of wireless a technology for that standard). Although the wireless a/n operate in the
same 5GHz frequency, this mode will only permit wireless a/n client devices to work and will
exclude any other wireless mode and devices that are not wireless a/n. (note: wireless b/g/n will
not be able to connect at the same time to the TEW-672GR with 5GHz wireless a/n mode
enable).
5GHz 802.11 wireless a/n mixed mode
26
2.4 GHz 802.11b/g/n mixed mode - This wireless mode works in the 2.4GHz frequency range
and will only allow the use of wireless g client devices to connect and access the TEW-672GR
at 11Mbps for wireless b, 54Mbps for wireless g and up to 300Mbps* for wireless n and share
access at the same time. Although the wireless b/g/n operates in the same 2.4GHz frequency, it
will allow the use of other 2.4GHz client devices (Wireless b/g/n) to connect and access at the

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 network name. Add up
to three additional SSIDs to create virtual wireless networks from one wireless Router 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.

Multiple SSID with the TEW-672GR
Frequency (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.
29
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. 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.
