Running a Link Test

The client utility's link test tool is designed to allow you to quickly evaluate the operation of the RF link
between your client adapter and the associated access point. The test can also be used to check the
operation of the wired link connected to the access point. The link test sends out TCP/IP Ping packets
to assess the operation of the link (RF link and wired link) between your client adapter and the
destination device specified by the IP address. Initially, the IP address of the associated access point is
automatically placed in the IP address field.
The link test does more than test the link between two network devices. It verifies that TCP/IP software
and the proper drivers have been loaded and are operating properly.
The following prerequisites are required before you can run a link test:
•
•
Follow the steps below to run a link test:
Click the LSM icon on the upper left of the Client Utility Advanced Properties Screen (see Figure 7-9).
Step 1
The LSM screen appears (see Figure 7-10).
In the IP Address field, you can enter a device IP address or use the IP address of the associated access
Step 2
point that is automatically placed in the field.
Note
Step 3 You can set the link test to run until it has completed a specific number of packets or to continuously run
until you stop it. Follow one of the steps below to determine how long the link test will run:
•
•
Step 4 Click the Start button to run the link test. While the test is running, statistics are displayed and updated
periodically. For additional information, see Table 7-6.
Step 5 If you did not set the link test to run continuously, the test ends after the specified number of packets is
sent, and the Stop button changes back to the Start button. To stop the link test at any time, click Stop.

The TCP/IP protocol must be installed and operational on your Macintosh computer.
Your Macintosh computer and the access point must have an IP address.
You can specify the IP address of a device on the wired link connected to the access point.
This allows the link test to check both the wireless and wired links.
Specify the number of packets (from 1 to 1000) that the link test sends by typing the number in the
Number of Packets field. (The Number of Packets parameter is ignored if the Continuous check box
is selected.)
Click the Continuous check box to allow the link test to run continuously.
