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.
