Appendix A Network Troubleshooting

If your ping test fails to get a response, then you may see a message like this:

C:\>ping www.example.com

Pinging www.example.com [192.0.32.10] with 32 bytes of data:

Request timed out.

Request timed out.

Request timed out.

Request timed out.

Ping statistics for 192.0.32.10:

Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

C:\>

When a request times out it may mean:

your computer is not connected to the network

your Internet access device is not connected to the network

or the device which you are pinging is not connected to the network

If you think the destination is active but responding slowly, you can try increasing the ping timeout value from its default of 4 seconds (4000 milliseconds) to something like 8 seconds (or 8000 milliseconds).

C:\>ping -w 8000 www.example.com

A long ping response could indicate network problems:

on your side of the connection

between the start and end points of the connection

on the receiving end

To determine where the slowdown is, you may need to use traceroute.
