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.
-2-
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.
-3-
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.

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.

WEP (Wired Equivalent Privacy) is a data privacy mechanism based on a
64-bit/128-bit shared key algorithm. WEP encryption scrambles the
communication between your access points and client devices to keep the
communication private. However, if an intruder passively receives enough
packets encrypted by the same WEP key, the intruder can perform a
calculation to learn the key and use it to join your network.
- 20 -
Enable WEP
WEP (Wired Equivalent Privacy) encryption can be
used to ensure the security of your wireless network.
The window allows you to set to 64bit or 128bit
Encryption (WEP) by using either Passphrase or
Manual Entry methods.
Note: To allow Decryption and communication, all
wireless devices must share the identical encryption
key on the same network.
WEP key lengths
Select between 64-bit and 128-bit.
WEP key
You can enter WEP key here or use the default
settings shown in the next field.
Default WEP key to use Select one of the four keys to encrypt your data.
Only the key you select it in the “Default WEP key
to use” will take effect.
Deny unencrypted data To access this wireless network clients are required
to use encryption. This should be checked together
with the item “Enable WEP”.
Authentication
The authentication mode defines configuration
options for the sharing of wireless networks to
verify identity and access privileges of roaming
wireless network cards. You may choose between
Open, Shared Authentication, and Both.
If the access point is using "Open Authentication”,
then the wireless adapter will need to be set to the
same authentication mode.
Shared Authentication is when both the sender and
the recipient share a secret key.
Select Both for the network adapter to select the
Authentication mode automatically depending on
the access point Authentication mode.
