or company networks from remote loca-
tions
1.5 Buffalo Anywhere Networking
Mobile professionals can be productive
while traveling by accessing standards-based,
secure,high-speed connections in many
hotel,airports,convention centers, and
even coffee shops. TheWBR-B11 makes
extending your LAN simple,secure, scalable,
and manageable, in part through solutions
likeVPN,allowing mobile professionals to
take their offices on the road effortlessly.
When no wired broadband connections are
available,wireless solutions in public spaces
coupled withVPN can connect mobile work-
ers to their businesses. Buffalo’s access point
features make a home network system acces-
sible from anywhere.
Buffalo’s firewall function provides:
• Protection of personal data/files by either
eliminating the intruder on the spot or
sending intruders to a nonfunctional zone

3.3 Setup Overview
TheWBR-B11 CD contains the Client Man-
ager program. The Client Manager is used
for setting up and configuring the access
point and for monitoring the wireless signal
between theAP and client.
Specialized setups for security,filtering and
other features will be explained in later sec-
tions.
3.4 Open the Setup Screen
• Connect theWBR-B11 according to the
wiring instructions.

dress of 192.168.11.1 and Subnet Mask of
255.255.255.0.
Ex: The setting PC can use 192.168.11.2 as
an IP and 255.255.255.0 as the Subnet Mask
during setup unless a different IP range is
entered for theAirStation.

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.

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.
