ICMP Ping
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 Sto p Test is selected, the Wireless
Diagnostics application is closed or if the device switches between infrastr ucture and ad-hoc modes.
To open the ICMP Ping screen, select ICMP Ping in the Wireless Diagnostics screen.
