Before installing the AWK-1137C, make sure that all items in the Package Checklist are in the box. You will need
access to a notebook computer or PC equipped with an Ethernet port. The AWK-1137C has a default IP address
that must be used when connecting to the device for the first time.
•Step 1: Connect a power source.
The AWK-1137C can be powered by a DC power input.
•Step 2: Connect the AWK-1137C to a notebook or PC.
Since the AWK-1137C supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or
crossover cable to connect the AWK-1137C to a computer. The LED indicator on the AWK-1137C’s LAN port
will light up when a connection is established.
•Step 3: Set up the computer’s IP address.
Choose an IP address on the same subnet as the AWK-1137C. Since the AWK-1137C’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.
NOTE
After you
select Maintenance Load Factory Default and click the Submit button, the AWK-
1137C will be
reset to
factory default settings and the IP address will be reset to 192.168.127.253.

By default, the AWK-1137C’s operation mode is set to client. Detailed information about configuring the
AWK-1137C’s operation can be found in Chapter 3.
•Step 6: Test communications.
In the following sections we describe two test methods that can be used to ensure that a network
connection has been established.
Testing the Communication
After setting up the AWK-1137C for the first time, you can perform a simple test to make sure that the AWK can
establish a wireless connection with an AP and is functioning properly.
In this example, an AWK-1137C is configured as a client on the wireless network.

AirWorks AWK-3131A Getting Started

Testing Network Connectivity on AWK-1137C
Connect an AWK-3131A (or another access point) in AP mode to Notebook A. Connect an AWK-1137C to
Notebook B. Configure the AWK-1137C and AWK-1137C with the same SSID and set their IP addresses as
shown in the following figure:
After configuring the WLAN card, establish a wireless connection with the AWK-1137C and open a DOS window
on Notebook B. At the prompt, type
ping <IP address of notebook A>
and then press Enter (see the figure below). A “Reply from IP address …” response means the communication
was successful. A “Request timed out.” response means the communication failed. In this case, recheck the
configuration to make sure the connections are correct.
