Checking Network Connection Status
You can check the network connection status of a device (i.e. whether it is connected to the network or
not).
1.
In the
Device Pane
, select one or more devices and right-click them to display a menu.
2.
Select
Check Connection Status
.
3.
Select the utility you want to use to check the connection status of the device. You can choose
from:
Ping
—A basic Internet program that lets you verify that a particular Internet address exists
and can accept requests. Pinging is diagnostically used to ensure that a host computer, which
you are trying to reach, actually operates.
Trace Route
—This diagnostic tool determines the path taken to a destination by sending
ICMP Echo Request messages with varying Time to Live (TTL) values to the destination. Each
router along the path is required to decrement the TTL in an IP packet by at least 1 before
forwarding it. Effectively, the TTL is a maximum link counter. When the TTL on a packet
reaches 0, the router is expected to return an ICMP Time Exceeded message to the source
computer.
A window displaying the network connection status of the device will appear.
