Running an RF Link Test
Step 2 In the IP Address of Access Point field, enter the IP address of the access point or other wireless device
with which you want to test the RF link.
Step 3 You can set the link test to run until it has attempted to send a specific number of packets or to run until
you stop it. Follow one of the steps below to determine how long the link test will run:
• Select the number of packets that the link test should attempt to send. You can type a number in the
Number of Packets field or use the slider to select this value. (The Number of Packets parameter is
ignored if the Continuous Linktest check box is checked.)
Range: 1 to 1000
Default: 4
• Check the Continuous Linktest check box to allow the link test to run continuously.
Default: Unchecked
Step 4 Select the size of the data packet that is to be sent to the access point. You can type a number in the Packet
Size field or use the slider to select this value.
Range: 64 to 2048
Default: 100
Note The Windows TCP/IP stack fragments (splits up) packets that are greater than 512 bytes.
Therefore, the number of transmitted packets does not match the number of received packets
(even if none are lost) if the packet size is greater than 512 bytes.
Step 5 Click the Start button to run the link test. While the test is running, statistics are displayed and updated
periodically.
Figure 7-7 shows the Linktest screen with the signal strength values displayed as percentages, and
Figure 7-8 shows the bottom of the same screen with the signal strength values displayed in dBm.
