NI WAP-3701/3711 User’s Manual Getting Started
First-Time Installation and Configuration
Before installing the NI WAP-3701/3711, check to make sure that all items in the Package
Checklist are in the box. In addition, you will need access to a notebook computer or PC equipped
with an Ethernet port. The NI WAP-3701/3711 has a default IP address that you must use when
connecting to the NI WAP-3701/3711 for the first time.
NOTE
NOTE
For testing requirements, if you only have one NI WAP-3701/3711, we strongly suggest that you
prepare a notebook computer or PC with a wireless LAN adapter installed. After finishing the
installation and configuration, you should test the NI WAP-3701/3711 to make sure the wireless
transmission is working normally.
Step 1: Select the Power Source
The NI WAP-3701/3711 can be powered by a DC power input, or by PoE (Power over Ethernet).
The NI WAP-3701/3711 will use the power source that you choose.
The PoE capability of the bridge is PowerDsine-compatible. Please visit PowerDsine’s website
for more information (
Step 2: Connect the NI WAP-3701/3711 to a notebook or PC
Since the NI WAP-3701/3711 supports MID/MID-X auto-sensing, you can use either a
straight-through cable or cross-over cable to connect the NI WAP-3701/3711 to the notebook. If
the LAN LED on the NI WAP-3701/3711’s front panel lights up, it means the connection is
established.
Step 3: Set up the computer’s IP address
In a Windows environment, the computer’s IP address can be changed in the TCP/IP settings
window. Select an IP address on the same subnet as the NI WAP-3701/3711. Since the NI
WAP-3701/3711’s default IP address is 192.168.127.253, and the subnet mask is 255.255.255.0,
you should set the IP address of the computer to 192.168.127.xxx.
http://www.powerdsine.com).
Step 4: Use the web-based manager to configure the NI WAP-3701/3711
Open your computer’s web browser and type http://192.168.127.253 in the address box to access
the homepage of the web-based Network Manager. Before the homepage opens, you will need to
enter the user name and password as shown in the following figure. For first-time configuration,
enter the default user name and password and then click on OK:
Default user name & password
User name: admin
Password: root
192.168.127.253
2-2
NI WAP-3701/3711 User’s Manual Getting Started
NOTE
For security reasons, we strongly recommend changing the password. To do this, open the
Network Manager homepage, click on General Æ Password, and then follow the onscreen
instructions.
Step 5: Select the Operational Mode for NI WAP-3701/3711
By default, the NI WAP-3701/3711’s operation mode is set to AP/Bridge. If you want to change
the setting, click on General Æ Operational Mode, as shown in the following figure, select an
operation mode, and then click on Save to activate the change.
Go to the General, Operational Mode section, select an operational mode and then click Save at
the bottom of this page. This will take you back to the starting page.
NOTE
The AP supports 2 operational modes:
y AP/Bridge
This mode provides both Access Point and Static LAN-to-LAN Bridging functionality. The
static LAN-to-LAN bridging function is supported through WDS (Wireless Distribution
System).
y AP 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 NI WAP-3701/3711 forwards
packets between its Ethernet interface and wireless interface for wired hosts on the Ethernet
side and wireless host(s) on the wireless side.
Detailed information about configuring the NI WAP-3701/3711’s Operation Mode is given in
Chapter 3.
2-3
NI WAP-3701/3711 User’s Manual Getting Started
Step 6: Configure the NI WAP-3701/3711’s IEEE 802.11 settings
Go to the IEEE 802.11 Communication section to configure IEEE 802.11g-related communication
settings, including Regulatory domain, Channel number, and Network name (SSID).
The number of available RF channels depends on local regulations; therefore, you will need to
choose an appropriate regulatory domain to comply with local regulations. The SSID of a wireless
client computer and the SSID of the NI WAP-3701/3711 must be identical for them to be able to
communicate with each other.
When you are finished, click on Save at the bottom of the page. This will return you to the home
page.
NOTE
Step 7: Review and Apply Settings
On the home page, you can review all of the settings you have made. Changes are highlighted in
red. If the changes are okay, click on Restart to restart the NI WAP-3701/3711 for the new
settings to take effect.
About 10 seconds are needed for the AP to complete its restart process.

NI WAP-3701/3711 User’s Manual Getting Started
Deploying the Access Point (AP)
After the settings have been configured, deploy the AP to the field application environment.
Connect the AP to an Ethernet LAN through an Ethernet switch or hub.
If you are configuring a pair of NI WAP-3701/3711 units for AP mode for a dynamic or static
bridging application and external high-gain directional antennas are used, it is difficult to adjust
alignments of the antennas when the two devices are separated by a long distance.
To adjust the alignments of a pair of bridges’ directional antennas:
1. Connect each bridge to a computer via Ethernet
2. Configure the date rate of each bridge to the lowest value, 1 Mbps.
3. Fix the alignment of the antenna on one side.
4. Adjust the alignment of the antenna on the other side by using response time information
obtained by pinging (i.e., running PING.exe) the “fixed-side” computer.
5. Fine-tune the alignment of the antenna until you get a best response time.
6. Increase the data rate of each bridge simultaneously until a maximum workable data rate is
reached. You may not be able to use the highest data rate, 54 Mbps, because of the distance
and the gain of the antennas.

Setting up Client Computers
The TCP/IP and IEEE 802.11g-related settings of wireless client computers must match those of
the Access Point.
Configuring IEEE 802.11g-related Settings
Open Internet Explorer and type the NI WAP-3701/3711’s IP address in the Address field. Press
Enter to establish the connection.
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
Access Point.
To establish a wireless link to an Access Point:
1. Launch the configuration/monitoring utility provided by the vendor of the installed WLAN
NIC.
2. Use the utility to make appropriate Operating Mode, SSID, and WEP settings.

NI WAP-3701/3711 User’s Manual Getting Started
NOTE
NOTE
NOTE
NOTE
A wireless client computer must be in infrastructure mode to associate with an AP.
The SSID of the wireless client computer and the SSID of the AP must be identical. Or, if the
SSID broadcast capability of the AP is enabled (default setting), the SSID of the wireless client
computer could be set to “any.”
Both the wireless client computer and the Access Point must have the same WEP settings for
them to communicate with each other.
For better wireless security, IEEE 802.1X capability of the Access Point must be enabled so that
only authenticated wireless users can access the wireless network.
Configuring TCP/IP-related Settings
Use the Windows Network Control Panel Applet to change the TCP/IP settings of the client
computers so that the IP addresses of the client computers and the IP address of the Access Point
are in the same IP subnetwork.
If a client computer is originally set up with a static IP address, you can either change its IP
address to match the IP address of the Access Point, or select the option
“automatically-obtain-an-IP-address” if there is a DHCP server on the network.
NOTE
For some versions of Windows, the computer needs to be restarted for the new TCP/IP settings to
take effect.
Confirming the Settings of the AP and Client Computers
After you have completed deploying the Access Point and setting up client computers, you must
make sure the settings you have made are correct.
Checking if the IEEE 802.11g-related Settings Work
To check if a wireless client computer can associate with the NI WAP-3701/3711:
1. Launch the configuration/monitoring utility provided by the vendor of the installed WLAN
NIC.
2. Check if the client computer is associated to an NI WAP-3701/3711. If the check fails, see
Appendix B, “Wireless Settings Problems,” to troubleshoot the problem.
Checking if the TCP/IP-related Settings Work
To check if a client computer can assess the Internet:
1. Open a Windows Command Prompt window on the client computer.
2. Type “ping AP”, where AP is the IP address of the Access Point. Replace it with your real IP
address—for example, 192.168.127.253, and then press Enter.
If the AP responds, go to the next step; otherwise see Appendix B, “TCP/IP Settings
Problems” to troubleshoot the problem.
2-6
NI WAP-3701/3711 User’s Manual Getting Started
3. Type “ping default_gateway”, where default_gateway is the IP address of the default gateway
of the wireless client computer, and then press Enter. If the gateway responds, go to the next
step; otherwise, see Appendix B, “TCP/IP Settings Problems,” to troubleshoot the problem.
4. Type “ping 1st_dns_server”, where 1st_dns_server is the IP address of the primary DNS
server of the wireless client computer, and then press Enter. If this DNS server responds, go
to the next step; otherwise, see Appendix B, “TCP/IP Settings Problems,” to troubleshoot the
problem.
