Trace Route Window
Trace Route
traces a packet from a computer to a host, showing how many hops the packet requires to reach the
host and how long each hop takes. The
Trace Route
utility identifies where the longest delays occur.
The
Trace Route
window allows testing a connection at the network layer (part of the IP protocol) between the
mobile computer and any place on the network.
To open the
Trace Route
window, tap
Trace Route
in the
Wireless Diagnostics
window.

Trace Route Window
Enter an IP address or a DNS Name in the IP combo box, and tap
Start Test
. The IP combo box should match the
information shown in the
ICMP Ping
window’s IP combo box. When starting a test, the trace route attempts to find
all routers between the mobile computer and the destination. The Round Trip Time (RTT) between the mobile
computer and each router appears, along with the total test time. The total test time may be longer than all RTTs
added together because it does not only include time on the network.
Known APs Window
The
Known APs
window displays the APs in range using the same ESSID as the mobile computer. This window is
only available in
Infrastructure
mode. To open the
Known APs
window, tap
Known APs
in the
Wireless Diagnostics
window.
