Chapter 6      Troubleshooting

Running the Ping Test

Step 5

Click 

Start

 to begin the carrier busy test.

When the test completes, the results are displayed on the page. For each of the channel center 
frequencies, the test produces a value indicating the percentage of time that the channel is busy. 

Running the Ping Test

You can use the ping test to evaluate the link to and from an associated wireless device. The ping test 
provides two modes of operation:

a.

Performs a test using a specified number of packets and then displays the test results.

b.

Performs a test that continuously operates until you stop the test and then displays the test results.

Follow these steps to activate the ping test:

Step 1

Use your web browser to access the access point browser interface.

Step 2

Click 

Association

 and the main association page displays.

Step 3

Click the MAC address of an associated wireless device and the Statistics page for that device displays.

Step 4

Click the 

Ping/Link Test

 tab and the Ping/Link Test page displays.

Step 5

If you want to specify the number of packets to use in the test, follow these steps:

a.

Enter the number of packets in the Number of Packets field

b.

Enter the packet size in the Packet Size field.

c.

Click 

Start

.

Step 6

If you want to use a continuous test, follow these steps:

a.

Enter the packet size in the Packet Size field.

b.

Click 

Start

 to activate the test.

c.

Click 

Stop 

to stop the test.

When the test has completed, the test results are displayed at the bottom of the page. You should check 
for any lost packets that can indicate a problem with the wireless link. For best results, you should also 
perform this test several times.

Resetting to the Default Configuration

If you forget the password that allows you to configure the access point, you may need to completely 
reset the configuration. You can use the MODE button on the access point or the web-browser interface.

Note

The following steps reset 

all

 configuration settings to factory defaults, including passwords, WEP keys, 

the IP address, and the SSID.
