NI WAP-3701/3711 User’s Manual Getting Started
2-6
NOTE A wireless client computer must be in infrastructure mode to associate with an AP.
NOTE 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.”
NOTE Both the wireless client computer and the Access Point must have the same WEP settings for
them to communicate with each other.
NOTE 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.
