Wireless-N Access Point with Power Over Ethernet
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-N Access Point with Power Over Ethernet. This Access Point will allow you to
network wirelessly better than ever. An access point allows for greater range and mobility within your wireless
network while also allowing you to connect the wireless network to a wired environment. The Wireless-N Access
Point also offers the convenience of Power over Ethernet (PoE) capability (in addition to regular 12VDC power
adaptor), so it can receive data and power over a single Ethernet network cable.
This Access Point supports the latest 802.11n draft Specification by IEEE early 2006. It also support 802.11g and
802.11b clients in a mixed environment. This Access Point currently can support an 11n data rate up to 300
Mbps. Besides the higher data rate, 802.11n technology also promises longer coverage by using multiple
antennas to transmit and receive data streams in different directions. Users are encouraged to update their
firmware through www.linksys.com when 802.11n specification is finalized by IEEE to ensure compatibility with
all the wireless-N devices.
Networks are useful tools for sharing computer resources. You can access one printer from different computers
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video
games. So, networks are not only useful in homes and offices, they can also be fun.
PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called "wired".
access point: a device that allows wireless-equipped
computers and other devices to communicate with each
other and with devices on a wired network. Also used to
expand the range of a wireless network.
network: a series of computers or devices connected
together.
lan (local area network): the computers and networking
devices that make up your local network.
poe (power over ethernet): a technology enabling an
Ethernet network cable to deliver both data and power.
ethernet: network protocol defined in IEEE 802.3 standard
that specifies how data is placed on and retrieved from a
common transmission medium.
adapter: a device that adds network functionality to your
PC.
PCs equipped with wireless client cards or adapters can communicate without cumbersome cables. By sharing
the same wireless settings within their transmission radius, they form a wireless network. This is sometimes
called a WLAN, or Wireless Local Area Network. The Access Point bridges wireless networks of 802.11n, 802.11g
and 802.11b standards and wired networks.
802.11n: wireless networking draft standard that specifies
a maximum data rate up to 600Mbps (300Mbps supported
by this device), an operating frequency of 2.4GHz, and
backward compatibility with 802.11b/g devices.
Use the instructions in this Guide to help you connect the Access Point, set it up, and configure it to bridge your
different networks. These instructions should be all you need to get the most out of the Access Point.
802.11g: a wireless networking standard that specifies a
maximum data transfer rate of 54Mbps, an operating
frequency of 2.4GHz, and backward compatibility with
802.11b devices.
802.11b: a wireless networking standard that specifies a
maximum data transfer rate of 11Mbps and an operating
frequency of 2.4GHz.

Chapter 2: Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one or more wireless adapters. Computers in a
wireless network must be configured to share the same radio channel to talk to each other. Several PCs equipped
with wireless cards or adapters can communicate with each other to form an ad-hoc network without the use of
an access point.
Linksys also provides products to allow wireless adaptors to access wired network through a bridge such as the
wireless access point, or wireless router. An integrated wireless and wired network is called an infrastructure
network. Each wireless PC in an infrastructure network can talk to any computer in a wired or wireless network
via the access point or wireless router.
ad-hoc: a group of wireless devices communicating directly
with each other (peer-to-peer) without the use of an access
point.
infrastructure: a wireless network that is bridged to a wired
network via an access point.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and may double the
effective wireless transmission range for two wireless adapter PCs. Since an Access Point is able to forward data
within a network, the effective transmission range in an infrastructure network may be more than doubled since
Access Point can transmit signal at higher power to the wireless space.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they
both share the same wireless network (SSID) and wireless security settings.
roaming: the ability to take a wireless device from one
access point's range to another without losing the
connection.
ssid: your wireless network's name
This Access Point has 802.11F Inter-Access Point Protocol (IAPP) to complete the roaming process in seconds. If
your wireless networks share the same IP subnet, this will not disrupt your data connection while moving around.
Before you consider roaming, choose a feasible radio channel and optimum access point position. Proper access
point positioning combined with a clear radio signal will greatly enhance performance.
Network Layout
The Wireless-N Access Point has been designed for use with 802.11n, 802.11g and 802.11b products. The
Access Point is compatible with 802.11n, 802.11g and 802.11b adapters, such as the notebook adapters for your
laptop computers, PCI adapters for your desktop PCs, and USB adapters for all PCs when you want to enjoy

Wireless-N Access Point with Power Over Ethernet
wireless connectivity. These wireless products can also communicate with a 802.11n, 802.11g or 802.11b
wireless print server (if available).
To link your wired network with your wireless network, connect the Access Point’s Ethernet network port to any
switch or router with Power over Ethernet (PoE)—or a PoE injector, such as the Linksys WAPPOE or WAPPOE12.
Note that the 12 VDC on the WAPPOE12 is for the splitter output. Both PoE Injectors provide 48 VDC power output.
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at
www.linksys.com for more information about wireless products.

Chapter 5: Setting Up the Wireless-N Access Point
Overview
The Access Point has been designed to be functional right out of the box with the default settings. However, if
you'd like to change these settings, the Access Point can be configured through your web browser with the Webbased Utility. This chapter explains how to use the Utility to perform the most basic settings.
The Utility can be accessed via web browsers, such as Microsoft Internet Explorer or Mozilla Firefox through the
use of a computer that is networked with the Access Point.
For a basic network setup, most users only have to use the following screens of the Utility:
• Setup
On the Setup screen, enter your basic network settings (IP address) here.
• Management
Click the Administration tab and then select the Management screen. The Access Point’s default password
is admin. To secure the Access Point, change the AP Password from its default.
HAVE YOU: Enabled TCP/IP on your PCs? PCs
communicate over the network with this
protocol. Refer to “Appendix D: Windows Help”
for more information on TCP/IP.
tcp/ip: a set of protocols PCs use to
communicate over a network.
browser: an application that provides a way to
look at and interact with all the information on the
World Wide Web.
Most users will also customize their wireless settings:
• Wireless
On the Wireless screen, change default SSID under the Basic Wireless Settings Tab. Select the level of
security under the Wireless Security Tab and complete the options for the selected security mode.
Accessing the Utility
There are three ways to connect to your Access Point for the first time.
1. If you have a 48VDC Power Injector (e.g. Linksys WAPPOE), power up your Access Point first, then connect the
Injector’s cable to your PC. Configure your PC to have the static IP address on the same subnet as the Access
Point’s default IP address (192.168.1.245).
2. If you have a PoE switch (e.g. Linksys SRW224P), connect your Access Point and your PC to the same
network. Configure your PC to have the static IP address on the same subnet as the Access Point’s default IP
address (192.168.1.245). Or if there is a DHCP server connected to the switch, configure it to assign the IP
address in 192.168.1.0/24 subnet. Your PC will get an IP address in the subnet through the DHCP.

The Wireless - Advanced Wireless Settings Tab
This screen allows you to configure the advanced settings for the Access Point. The Wireless-N adopts several
new parameters to adjust the channel bandwidth, and guard intervals to improve the data rate dynamically.
Linksys recommends to let your Access Point automatically adjust the parameters for maximum data throughput.
Advanced Wireless
You can change the following advanced parameters (some only for Wireless-N) for this Access Point. Wireless-N
data rates are classified into 16 MCS numbers (0-15). MCS stands for Modulation and Coding Scheme. For the
same MCS number, the data rate changes according to the Channel Bandwidth and Guard Interval settings. You
can see the change through the drop-down menu of Tx Rate Limiting (11n clients).
Channel Bandwidth. You can select the channel bandwidth manually for Wireless-N connections. When it is set
to 20MHz, only the 20MHz channel is used. When it is set to 40MHz, Wireless-N connections will use 40MHz
channel but Wireless-B and Wireless-G will still use 20MHz channel. The default is Auto.
Figure 6-16: Wireless - Advanced Wireless
Guard Interval. You can select the guard interval manually for Wireless-N connections. The two options are
Short (400ns) and Long (800ns). The default is Auto.
Tx Rate Limiting (11b clients). This option provides rate limiting on Wireless-B connections. Wireless-B clients
can be limited to data rate specified by IEEE 802.11b. The default is Auto.
Tx Rate Limiting (11g clients). This option provides rate limiting on Wireless-G connections. Wireless-G clients
can be limited to data rates specified by IEEE 802.11g and 802.11b. The default is Auto.
Tx Rate Limiting (11n clients). This option provides rate limiting on Wireless-N connections. Wireless-N clients
can be limited to data rates specified by draft IEEE 802.11n, IEEE 802.11g, and 802.11b. The data rate associated
with each MCS number (0-15) changes according to your selection on Channel Bandwidth and Guard Interval.
The default is Auto.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode function boosts the Access Point’s ability to catch
all wireless transmissions, but will severely decrease performance. Keep the default setting, Auto, so the Access
Point can use this feature as needed, when the Wireless-N/G products are not able to transmit to the Access Point
in an environment with heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature.
WMM. Wi-Fi Multimedia is a QoS feature defined by WiFi Alliance before IEEE 802.11e was finalized. Now it is
part of IEEE 802.11e. When it is enabled, it provides four priority queues for different types of traffic. It
automatically maps the incoming packets to the appropriate queues based on QoS settings (in IP or layer 2
header). WMM provides the capability to prioritize traffic in your environment. The default in Enabled. Select

High Performance (N-Only) if you want to achieve highest throughput on 11n connections. Note that 11b and
11g clients performance will be affected by setting to this mode.
IOT Mode. Interoperability Mode. Enabling this mode will help this AP to communicate with Linksys retail client
cards (e.g. WPC300N) at 11n rates. This mode is a temporary measure to cope with implementation differences
on 802.11n draft specification. This option will be removed eventually when IEEE802.11n is finalized. The default
is disabled.
Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by
the Access Point to keep the network synchronized. A beacon includes the wireless networks service area, the
Access Point address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and
the Traffic Indicator Message (TIM). The default is 100 ms.
DTIM Interval. This value indicates how often the Access Point sends out a Delivery Traffic Indication Message
(DTIM). Lower settings result in more efficient networking, while preventing your PC from dropping into powersaving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving power, but interferes with
wireless transmissions. The default is 1 ms.
RTS Threshold. This setting determines how large a packet can be before the Access Point coordinates
transmission and reception to ensure efficient communication. This value should remain at its default setting of
2347. If you encounter inconsistent data flow, only minor modifications are recommended.
