2.2 Connecting the Managing PC and the
SP915A
To connect the Ethernet managing computer and the managed AP for first-
time configuration, users have two choices as illustrated in diagram below.
(Note: One connector of the Ethernet cable must be plugged into the
LAN/CONFIG Ethernet jack of the SP915A for configuration.)
2.3 Preparing for Configuration
For users to configure the SP915A, a managing computer with a Web
browser is needed. For first-time configuration of an SP915A, an Ethernet
network interface card (NIC) should have been installed in the managing
computer.
(Note: If users are using the browser, Opera, to configure an AP, click the
menu item <File>, click <Preferences...>, click <File types>, and <edit> the
<MIME> type, <text/html>, to add a file extension “.sht” so that Opera can
work properly with the Web management pages of the AP.)
5

PC/Notebook must belong in the same IP range and subnet. Follow the steps
below to configure IP settings for LAN PC.
Step 1. In the control panel, double
click on Network Connections. Double
click on the local area connection
(e.g. LAN). The following screen will
appear.
Step 2. Select ‘Internet Protocol
(TCP/IP)’, and then click on the
‘Properties’ button. The screen will
appear to allow entry of TCP/IP settings.
Step 3. Select ‘Use the following IP Address’ button and then enter the IP
address and subnet mask. Ensure the IP address and subnet mask are on
the same subnet as the Access Point. Click on ‘OK’ button to save the setting.
6

IP Address 192.168.0.1
Subnet Mask 255.255.255.0
Username root
Password root
2.4 Accessing Web-based User Interface
SP915A is embedded with web-based management user interface and
provides a series of web pages, which display the configuration and status of
the system. After configuration of IP, the management interface can be
access by entering the IP address of the router into the browser.
Step 1. Login page will appear to prompt users to enter the username and
password.
Step 2. After entering the correct login detail, the browser will forward the
webpage to the setup page. Users can begin configuring the Access Point.
For detail information, refer to the user manual.

2.5 Quick Setup via Web-Based UI
Follow the following steps for quick setup of your wireless AP. Click <Save>
at the bottom of each configuration interface to save changes.
2.5.1 Operational Mode
Go to the ‘General’ menu and click <Operational Mode> to select a mode for
the AP.
The AP supports 2 operational modes:
yAP/Bridge: This mode provides both Access Point and Static LAN-to-
LAN Bridging functionality. The static LAN-to-LAN bridging function is
supported through Wireless Distribution System (WDS).
8

yAP Client: This mode is for Dynamic LAN-to-LAN Bridging. The AP
Client automatically establishes bridge links with APs from any
vendors.
In either mode, the AP forwards packets between its Ethernet interface and
wireless interface for wired hosts on the Ethernet side and wireless host(s) on
the wireless side.
There are 2 types of wireless links as specified by the IEEE 802.11 standard.
ySTA-AP: This type of wireless link is established between an IEEE
802.11 Station (STA) and an IEEE 802.11 Access Point (AP). An STA
is usually a client computer (PC or PDA) with a WLAN network
interface card (NIC). The AP Client mode is actually an STA.
yWDS: This type of wireless link is established between two IEEE
802.11 APs. Wireless packets transmitted along the WDS link comply
with the IEEE 802.11 WDS (Wireless Distribution System) format at
the link layer.
The relationships among the operational modes and the wireless link types
are shown in the following table:
AP/Bridge AP Client
AP/Bridge WDS STA-AP
AP Client STA-AP
To establish a static bridge link based on WDS, the AP/bridges at both end of
the WDS link must be manually configured with each other’s MAC addresses.
To establish a dynamic bridge link between an AP and an AP Client, both
devices have to be configured with the same SSID and WEP settings. The
AP Client automatically scans for any AP that is using the matched SSID and
establishes a bridge link with the scanned AP.

2.5.2 IP Address
Go to the ‘TCP/IP’ menu and click <Addressing> to alter the IP configuration
for the AP.
2.5.3 Wireless Settings
Go to the ‘IEEE 802.11’ menu and click <Communication> to set wireless
parameters for the AP.
2.5.4 Restart Device
After pressing <Save> on each page, the interface will be bought back to
Start Page. The changes will be highlighted in red. Press <Restart> to apply
the changes.
10

2.6 Installation
For configuring a pair of APs for dynamic or static bridging with high grain
directional antenna, please follow the steps below.
Step 1. Connect each bridge to a computer via Ethernet and configure the
data rate of each AP to the lowest value, 1Mbps.
Step 2. Fix the alignment of the antenna on one side. Run ‘PING’ function in
DOS environment between the two APs. Response time from the ‘PING’ will
indicate the optimal alignment.
Step 3. Increase the data rate of both bridges until the maximum limit is
reached for a stable connection. The data rate will be limited by distance and
the gain of the antenna.
11

(Note: When doing dynamic bridging, configure Bridge 1 to be in AP Client
mode and configure Bridge 2 to be in AP/Bridge mode.)
2.7 Setting up Client Computers
The TCP/IP and IEEE 802.11b-related settings of wireless client computers
must match those of the AP.
2.7.1 Configuring SP915A Related Settings
Before the TCP/IP networking system of a wireless client computer can
communicate with other hosts, the underlying wireless link must be
established between this wireless computer and an AP.
To establish wireless link to the AP:
yLaunch the configuration/monitoring utility provided by the vendor of
the installed WLAN NIC.
yUse the utility to make appropriate Operating Mode, SSID and WEP
settings.
12

yA wireless client computer must be in infrastructure mode, so that it
can associate with an AP.
yThe SSID of the wireless client computer and the SSID of the AP
must be identical. Or, in case the SSID broadcasts capability of the
AP is enabled (by default), the SSID of the wireless client computer
could be set to “any”.
yBoth the wireless client computer and the AP must have the same
WEP settings for them to communicate with each other.

3.3 Status Menu
3.3.1 Wireless Clients
On this page, the status information of each associated client, including its
MAC address, IP address, user name (if the client has been IEEE 802.1x
authenticated), number of bytes it has send, number of bytes it has received,
and the time of its last activity, are shown.
3.3.2 DHCP Mappings
On this page, all the current static or dynamic DHCP mappings are shown. A
DHCP mapping is a correspondence relationship between an IP address
assigned by the DHCP server and a computer or device that obtains the IP
address. A computer or device that acts as a DHCP client is identified by its
MAC address.
