USING AIRSTATION
FOR ADVANCED
CONFIGURATIONS
Although yourAirStation will function fine
using only the settings from Section 3,you
may wish to explore more advanced options.
This chapter explains each parameter in the
Advanced button. Click the Top tab
and click the Advanced button.
4.1 LAN Setting
Set up LAN connections.
4.1.1Wireless
Wireless LAN operation setup.
ESS-ID - Allows administrator to alter the
ESS-ID of the AirStation. To communicate
with a specific AP only, the AP’s ESS-ID
must be entered in the client PC. The client
PC looks for the specificAP (or ESS-ID)
for wireless communication. Use up to 32
alphanumeric characters for the ESS-ID (case
sensitive).
■ Note: Roaming -When multiple AirSta-
tions have an identical ESS-ID,WEP, and DS
channel,client PCs may Roam between the
AirStations.
Wireless Channel - Select the channel
used for wireless communication. There are
11 overlapping channels.Channels 1,6 and
11 are non-overlapping.
If there are multipleAPs in close proximity
using the same channel,there may be inter-
ference. In this case, change to a non-over-
lapping channel.
■ Note: This parameter is automatically set

in the client computer.
Encryption Key (WEP) - Select En-
crypt or Do not encrypt. Create and
enter an encryption code to protect wireless
communications. It is possible to enter up to
4 differentWEPs. TheWEP key must match
between two parties for secure communic-
ations.
Examples ofWEP key:
64bit ASCII: 5 digits of alphanumeric charac-
ters,“ab34Y”
128bit ASCII: 13 digits of alphanumeric char-
acters,“123456abcdef7”
■Note: ASCIIWEP is case sensitive.
64bit HEX: 10 digits,using characters 0-9 and
a-f,“00234ABCDE”
128bit HEX: 26 digits,using characters 0-9
and a-f,“20123456789abcdeabcdeabcde”
BSS (Basic Service Set) Basic Rate
Set -The transmission data rate between
devices. If one device supports 2Mbps only,
the data rate for the entire network should
be limited to 2Mbps (“Default”selection).
Otherwise,use 11Mbps max (“All”selection).
DTIM Period - An access point transmits
beacon signals to nearby clients at a preset
interval. This parameter sets the beacon
transmission interval time (1-255 sec.).
Selection of a larger number may conserve
energy for the client PC (when client power
management is enabled),but may delay wire-
less communication. The default value of 1 is
recommended.
ANY Connection - Enables a client
PC to connect to the nearestWBR-B11 by
entering the word“any”for the ESS-ID. If
the“ANY Connection”is not selected, the
WBR-B11 will not be found unless the
specificWBR-B11’s ESS-ID is entered in the
client PC.
4.1.2 LAN port
Set LAN interface parameters.

a different range, the setting PC’s IP must
be changed to the same range to continue
configuration. Then restart the setup session
from the AirStation utility screen.
DHCP Server Function Simple Set-
ting - Allows administrator to enable/disable
the DHCP server function for theAirStation
LAN side. Select Use to enable and Do

10
IPs to be excluded from the range specific-
ation should be entered in the specified field.
Lease period - Specifies the number of
hours (1-999) an assigned IP address is valid.
The client PC will request a renewal of IP ad-
dress at the end of the valid time period.
Default Gateway - Allows administra-
tor to use the Default Gateway address
(the AirStation’s IP address),assign a specific
Gateway address,or block clients from Gate-
way notification.
