Chapter 2 Wireless LAN Access Point
Connection
1. Locate an optimum location for the Wireless LAN Access Point.
The best location for your Wireless LAN Access Point is usually at the center of
your wireless network, with line of sight to all of your mobile stations.
2. Connect the Wireless LAN Access Point to your 10/100Mbps network.
Connect one end of standard UTP cable to the Wireless LAN Access Point’s
10/100Mbps RJ-45 connector and connect the other end of the cable to a switch or
a hub. The Wireless LAN Access Point will then be connected to your
10/100Mbps Network.
3. For configuration purposes, connect the Wireless LAN Access Point to your
PC through the USB port.
If the USB port of your PC is working properly, your system should immediately
recognize the Access Point and attempt to install a driver for it. Make sure that the
Setup CD is inserted into your CD-ROM drive and then follow the instructions of
the setup program. Select Specify a location and type in the blank field D:\
Driver\Winxxx (where “D” specifies your CD-ROM) to install the driver
automatically. The driver supports Windows 98/98SE/Me/2000/XP operating
systems.
Note: Windows 2000 driver can also be used as Windows XP driver.
4. Connect the AC Power Adapter to the Wireless LAN Access Point’s Power
Socket.

The parameters for the Wireless LAN Access Point are described below:
Parameters Description
MAC Address The MAC Address of the Access Point.
Regulatory Domain This parameter is used to designate the Access Point’s
regulatory domain. There are seven domains you can set
including FCC, DOC, ETSI, SPAIN, FRANCE, MKK
and MKK1. Note that the Regulatory Domain and the
Wireless Channel parameter have the specific
corresponding relation listed as below.

be unique to your network. The default IP Address of
Access Point is 10.170.254.32.
Ethernet Subnet Mask The Ethernet station and the Access Point must be on the
same subnet. The IP address for the Access Point must
correspond to the Subnet Mask. The default Subnet Mask
of Access Point is 255.255.254.0.
Wireless MAC Address Specifies the BSSID. It must be the same as the Ethernet
MAC Address.
ESSID The ESSID (up to 32 printable ASCII characters) is the
unique name identified in a WLAN. The ID prevents the

Parameters Description
Auto Rate Fall Back Select Enable or Disable. When this is enabled, the
wireless network provides more flexibility when wireless
devices roam. As wireless devices move away from the
Access Point, the transfer rate will automatically fall
back to the most optimum rate allowed.
Wireless Channel Select the channel to be used. Channels differ from
country to country. There are 14 channels available.
WEP type Select the 64(40) or 128 bits Wired Equivalent Privacy
Algorithm.
WEP key Select one of the keys (1~4) as the WEP encryption key
for transmissions between stations and the Access Point.
Wireless Fragmentation
Threshold
The size of the packets to be fragmented. Enter a value
within a range of 256 to 2346 bytes.
Wireless RTS Threshold Minimum packet size required for an RTS (Request To
Send) transmission. For packets smaller than this
threshold, an RTS is not sent and the packet is
transmitted directly to the WLAN. The value is in a range
of 256 to 2346 bytes.
WEP Keys #1 - #4 The default key that will be used. May be edited when
WEP type is 64(40) bits. Enter 10 digit Hex values (in the
range of “A-F”, “a-f” and “0-9”) as the encryption keys.
Preamble Type The preamble defines the length of the CRC block for
communication between the Wireless LAN Access Point
and the roaming Wireless Stations. The Short Preamble
option improves throughput performance.
