The ICMP Ping screen allows testing of a connection at the network layer (part of the IP protocol) between the 
device and any other device on the network. Ping tests only stop when Stop Test is selected, the Wireless 
Diagnostics application is closed or if the device switches between infrastructure and ad-hoc modes.

To open the ICMP Ping screen, select ICMP Ping in the Wireless Diagnostics screen.

To perform an ICMP ping:

In the IP field, enter an IP address or select an IP address from the drop-down list.

From the Size drop-down list, select a size value.

Select Start Test. The ICMP Ping test starts. Information of the ping test displays in the appropriate fields. The 
following statistics appear on the page:

Signal:

The current signal strength, measured in dBm, is provided both as a numerical value and as a 
histogram.

Noise:

The current noise level, measured in dBm, is provided both as a numerical value and as a 
histogram.

SNR:

The current signal to noise ratio, measured in dBm, is provided both as a numerical value and as 
a histogram.

Total Tx:

The total number of pings sent is displayed numerically.

Total Rx:

The total number of valid ping responses received is displayed numerically.

Lost:

The total number of pings that were lost is displayed numerically.

RT Times:

Four round trip times: Last, Average, Minimum and Maximum are displayed in milliseconds.
