FEDERAL COMMUNICATIONS COMMISSION
INTERFERENCE STATEMENT
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-- Consult the dealer or an experienced radio/TV technician for help.
CAUTION
Any changes or modifications not expressly approved by the grantee of this device could void the
user's authority to operate the equipment.
FCC RF Radiation Exposure Statement

Introduction
The WL-5420AP is an IEEE802.11g compliant access point, it not only
provides a high transfer rate up to 54Mbps, which is almost five times faster
than the already existing 11Mbps 802.11b products, but is also backward
compatible with the Wireless B equipments.
The WL-5420AP provides 64/128 bit WEP encryption and IEEE802.1x
which ensures a high level of security to protects users’data and privacy.
The MAC Address filter prevents the unauthorized MAC Addresses from
accessing your Wireless LAN. Your network security is therefore double
assured.
This device can support three modes, i.e. Access Point and Bridge.While
acting as a Bridge, this device connects wireless stations for inter-LAN
connection.
Placed anywhere along with an Ethernet LAN, the WL-5420AP allows up to
200 wireless stations within its area of coverage to access transparently to the
corporate network.
The web-based configuration utility allows users to configure via web
browser. Advanced setup and firmware upgrade can be done easily.

About the Operation Modes
This device provides multiple operational applications with Access Point,
Client, and Bridge (Infrastructure and Ad-hoc) modes, which are mutually
exclusive.
1. Access Point: When acting as an access point, this device connects all
the wireless points (PCs) to a wired network. See the sample application
below.
If you are currently in Bridge mode and want to change to Access Point,
perform the Firmware Upgrade to upload the firmware from the included
CD for Access Point mode. Refer to the section titled “Upgrade system
firmware”for details.

-3-
2. Bridge (Infrastructure): When acting as a Bridge, this device serves as
a wireless client that connects wired stations (refer to the following
illustration) to other access point(s). When becomes a wireless station
(AP1 plus the connected computer 1, 2 and 3) can have the Internet
access if the other Access Point (AP2) has the Internet connection.
If you are currently in Access Point mode and want to change to Bridge,
perform the Firmware Upgrade to upload the firmware from the included
CD for Access Point mode. Refer to the section titled “Upgrade system
firmware”for details.

-4-
3. Bridge (Ad-hoc): When set to the Bridge (Ad-hoc) mode, this device
can only work when connected to a computer, and will work like a
wireless station. You can share files and printers between wireless
stations (PC and laptop with wireless network adapter installed).
The Bridge (Ad-hoc) mode is only for inter-LAN connection and will
not communicate with any wired network.
This device is shipped with configuration that is functional right out of the
box. If you want to change the settings in order to perform more advanced
configuration or even change the mode of operation, you can use the
web-based utility provided by the manufacturer as described in the following
sections.

Getting Connected
1. Find a Location: choose a location to place the access point. Usually,
the best place for the access point is at the center of your wireless
network, with line of straight to all your wireless stations.
2. Adjust the Antenna: usually the higher the antenna is placed, the better
will be the performance.
3. Connect to your local area network: connect a straight or a crossover
Ethernet cable to one of the Ethernet port of the access point, and the
other end to a hub or switch. (If you are using a straight Ethernet cable,
make sure the II-X button is switched right; the other way for Cross
Ethernet cable.)
4. Power on the device: connect the included AC power adapter to the
access point’s power port and the other end to a wall outlet. Note: use
only the power adapter that provided with the access point. Using a
different power adapter may cause permanent damage to the device.

WPA AP -Configuration via Web
Login
1. Open the browser, enter the local port IP address of the Device
(default at 192.168.1. 240), and click “Go” to get the login page.
2. The user name and password are not required and should be left blank

Wireless (Wireless Configuration)
Here you can set/change wireless configuration including visibility status,
Wireless Mode, SSID, channel, transmission rate … etc. See the
description that comes after each function.
When you are done with the change, remember to restart this access point to
let the new settings take effect.
Visibility Status If you select invisible, this AP can not be
detected by wireless sniffers; which means
all the wireless clients can not associated to
this AP unless they know/use the SSID.
Wireless Mode You can select different wireless
networking mode to meet your wireless
environment or for optimal performance.
You can choose from the list.

Wireless Network Name (SSID)
The SSID is the unique name
shared among
all points in your wireless network. The
name must be identical for all devices and
points attempting to connect to the same
network.
Channel Shows the selected channel that is currently
in use. (There are 14 channels available,
depending on the country.)
Transmission rate (Mbps) Shows the current transfer rate
There are Best (Automatic), Fixed 1, 2, 5.5,
6, 9, 11, 12, 18, 24, 36, 48, and 54Mbps.)

Access (Access Control)
This AP provides MAC Address filtering, which prevents the unauthorized
MAC Addresses from accessing your Wireless LAN.
Once you check to enable access control, only MAC addresses entered in
following fields are allowed to associate to this AP.
Note:
1. You can enter 16 MAC Addresses to associate to this AP.
2. You can copy the MAC addresses shown on the Station List and past
them to the MAC address table to save the effort of typing and avoid
typo as well.

transmission. The performance will be
decreased as well, thus a noisy environment
is recommended.
RTS Threshold RTS (Request To Send) is a control frame
sent from the transmitting station to the
receiving station
requesting permission to
transmit. This value is recommended to

remain at its default setting of 2432
.
Should you encounter inconsistent data flow,
only minor modifications of this value are
recommended.
Beacon period This is also called Beacon Interval. This
value indicates the frequency interval of the
beacon. A beacon is a packet broadcast by the
AP to synchronize the wireless network. The
default value is 100.
DTIM interval DTIM stands for
Delivery Traffic Indication
Message. A DTIM is a countdown field
informing clients of the next window for
listening to broadcast and multicast messages.
When the access point has buffered broadcast
or multicast message for associated clients, it
sends the next DTIM with a DTIM Interval
value. Access point clients hear and awaken
to receive the broadcast and multicast
messages.
Maximum burst time The amount of time the radio will be reserved
to send data without requiring an
ACK. Adding a burst time should help
throughput for 802.11g clients when AP is
running in mixed mode. This number is in
units of microseconds. A typical value would
be 650 microseconds. When this number is
zero, bursting is disabled.
Enable PSM buffer PSM stands for Power Save
Mechanisms. Turn this on to enable support
for stations in power save mode.
