Installation Notes
In order to establish a connection to the Internet it will be necessary to provide information to the
router that will be stored in its memory. For some users, only their account information (User
Name and Password) is required. For others, various parameters that control and define the
Internet connection will be required.
Internet Connection
The WL11N is intended for use with a broadband device such as an ADSL, xDSL or cable
(CATV) modem. The physical connection to the Internet must first be established through a
broadband device, typically this should be set up as an invisible bridge.
Operating Systems
The WL11N uses an HTML-based web interface for setup and management. The web
configuration manager may be accessed using any operating system capable of running web
browser software, including Microsoft Windows® operating systems.
Web Browser
Any common web browser can be used to configure the router using the web configuration
management software. The program is designed to work best with more recently released
browsers. The web browser must have JavaScript enabled. JavaScript is enabled by default on
many browsers. Make sure JavaScript has not been disabled by other software (such as virus
protection, firewall software or Internet security packages) that may be running on your computer.
Ethernet or Wireless Adapter
Any computer that uses the router must be able to connect to it through an Ethernet port or
through the wireless 802.11n/g/b connection. The computer therefore must have either an
Ethernet adapter or 802.11n/g/b adapter installed. Network adapters are standard for most
computers sold presently.

Connecting Devices to the Router
The Wireless Broadband Router connects three separate networks, a private Ethernet LAN,
Wireless LAN and the public Internet (WAN). Choose a location for the router where Ethernet
devices can be connected to the LAN ports and the WAN port can be easily connected to the
cable modem or DSL modem that provides the broadband Internet connection. Typically the
broadband device is configured as a bridge, however some devices allow for more complex
options. Consult the user manual of the broadband device for more information on how best to
configure the broadband Internet connection.
The router should be protected from dust, water, moisture and heat. Make sure network cables,
power adapters and power cords are placed safely out of the way so they do not create a
tripping hazard. As with any electrical appliance, observe common sense safety procedures.
Place the router on a shelf, desktop, or other secure stable platform. Ideally you should be able
to view the LED indicators on the front panel.
Connect Router to Ethernet
The router can be connected to computers or other Ethernet devices using the four Ethernet
LAN ports on the rear panel. Any connection to an Ethernet concentrating device such as a
switch or hub must operate at a speed of 10/100 Mbps only. When connecting the router to any
Ethernet device capable of operating at speeds between 10~100Mbps, be sure that the device
has auto-negotiation (NWay) enabled for the connecting port. Use standard CAT5 or better
Ethernet cable with RJ-45 connectors. The Ethernet LAN ports are auto MDI-II/MDI-X so you
can use straight-through or crossover Ethernet cabling.
The rules governing Ethernet cable lengths apply to the LAN to router connection. Be sure the
Ethernet cables connected to the LAN ports do not exceed 100 meters in length.
Connecting through 802.11 Wireless
The default wireless settings of the access point allow roaming 802.11g and 802.11b wireless
clients to associate with it. The first time you set up the router however, use the Ethernet
connection to configure the channel and SSID. For wireless client-to-Internet connection through
the router, first configure the Internet connection through the Ethernet. When the Internet
connection has been established, make sure the wireless clients are configured as DHCP clients
if you are using the router’s DHCP server. Otherwise, make certain the wireless clients have IP
settings that allow them to use the router as a gateway to the Internet.
General Guide to Setting Up a Wireless Network
In order to get the best performance from the wireless component of the router, you should have
some basic understanding of how wireless networks operate. Wireless networking is a relatively
new technology and there are more factors to consider when setting up or designing a wireless
network than designing a wired network. If you are setting up a wireless network, especially if
you are using multiple access points and/or covering a large area, good planning from the outset
can ensure the best possible reliability, performance, coverage and effective security.
Radio
Wireless local network (as called WI-FI) devices such as notebook computers and wireless
access points use electromagnetic waves within a broad, unlicensed range of the radio spectrum
(between 2.4GHz and 2.5GHz) to transmit and receive radio signals. A wireless access point
(AP) becomes a base station for the wireless nodes (notebook computer for example) in its
LinkTek WL11N Wireless Broadband Router User Guide

broadcast range. Often a wireless access point such as the AP embedded in the LinkTek
WL11N, will also provide a connection to a wired network - usually Ethernet - and ultimately an
Internet connection. The IEEE 802.11 standard precisely defines the encoding techniques used
to digitally used for data transmission. The embedded wireless access point can be used by
IEEE 802.11g, 802.11b and 802.11n devices. These standards are compatible but use different
algorithms for data transmission.
802.11g uses a method called Orthogonal Frequency Division Multiplexing (OFDM) for
transmitting data at higher data rates. OFDM is a more efficient encoding method than Direct
Sequence Spread Spectrum (DSSS) transmission, the method used by 802.11b devices.
However, in order to support different data transmission rates while also be compatible with
802.11b, 802.11g uses a combination of OFDM and DSSS when 802.11b devices are present.
Range
An access point will send and receive signals within a limited range. Also, be aware that the
radio signals are emitted in all directions giving the access point a spherical operating range.
The physical environment in which the AP is operating can have a huge impact on its
effectiveness. If you experience low signal strength or slow throughput, consider positioning the
router in a different location. See the discussion below concerning the wireless environment and
location of the AP (LinkTek WL11N).
SSID and Channel
Wireless networks use an SSID (Service Set Identifier) as means of identifying a group of
wireless devices, similar to a domain or subnet. This allows wireless devices to roam from one
AP to another and remain connected. Wireless devices that wish to communicate with each
other must use the same SSID. Several access points can be set up using the same SSID so
that wireless stations can move from one location to another without losing connection to the
wireless network.
The embedded wireless access point of the router operates in Infrastructure mode. It controls
network access on the wireless interface in its broadcast area. It will allow access to the wireless
network to devices using the correct SSID after a negotiation process takes place. By default,
the LinkTek WL11N broadcasts its SSID so that any wireless station in range can learn the SSID
and ask permission to associate with it. Many wireless adapters are able to survey or scan the
wireless environment for access points. An access point in Infrastructure mode allows wireless
devices to survey that network and select an access point with which to associate. You may
disable SSID broadcasting in the web manager’s wireless menu.
In addition, the AP can use different channels (frequency bands) to avoid unwanted overlap or
interfere between control zones of separate APs. Wireless nodes must use the same SSID and
the same channel as the AP with which it wishes to associate. However, because of the nature
of the CSMA/CA (carrier sense multiple access with collision avoidance) protocol, using the
same channel on two different APs can contribute significantly to wireless congestion. If you are
using multiple APs on your network and are experiencing low throughput or significant
transmission delay, carefully consider how channels are assigned to the different APs.
Wireless Security
Various security options are available on the LinkTek WL11N including open or WEP and WPA
(including WPA-PSK). Authentication may use an open system or a shared key. Read below for
more information on configuring security for the wireless interface.

Installation Considerations for Wireless LAN
Many physical environmental factors can impact wireless networks. Radio waves are used to
carry the encoded data between devices. These radio transmissions can become degraded due
to signal attenuation, multi-path distortion and interference or noise. Attenuation simply means
that the strength of the signal weakens with the distance it travels, even if the transmission path
is unobstructed. Multi-path distortion occurs when radio signals bounce off objects like walls,
ceilings, metal appliances, etc. This may cause a signal to be duplicated, with each separate yet
identical signal arriving at a receiver at different times. Interference and noise from electrical
devices such as microwave ovens, fluorescent lights, automobile engines and other radio
emitting devices can cause signal degradation. With all of this in mind, choose a location for all
access points on the wireless LAN.
Wireless networking lets you access your network from nearly anywhere you want. However, the
number of walls, ceilings, or other objects that the wireless signals must pass through can limit
signal range. Typical ranges vary depending on the types of materials and background RF noise
in your home or business. To maximize range and signal strength, use these basic guidelines:
x
Keep the number of walls and ceilings between the access point and other network
devices to a minimum - each wall or ceiling can reduce your wireless device’s range from
3-90 feet (1-30 meters.) Position wireless devices so that the number of walls or ceilings
is minimized.
x
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.
x 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
dense, especially metallic, materials. Also, note that metal filing cabinets and appliances
can reflect radio signals. When these metal objects are moved around, your wireless
network may be affected.
x
Keep your access point away (at least 3-6 feet or 1-2 meters) from electrical devices or
appliances that generate extreme RF noise such as microwave ovens, CRT monitors,
motors, etc.
