ping
The ping command line utility allows you to verify the connection and latency
between your computer and either the P-2812HNU-51c or other devices on the
network. If you cannot reach a target using this command, then it may indicate
possible network trouble.
Syntax: ping target
The target can be an IP address or a host name.
Parameters: ping [-w timeout] target
The timeout parameter allows you to input the number of seconds (in
milliseconds) that your computer waits for a reply.
The following examples show the typical output of this command:

Ping statistics for 203.69.113.18:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 6ms, Maximum = 7ms, Average = 6ms
>
The number of bytes here indicates packet size. As most data is broken up into
smaller packets, this makes the ping test fairly representative of a typical network
connection. The default packet size on Windows is 32 bytes.
Time is the number of milliseconds the data requires to make the roundtrip
journey from your computer to the destination host and back again. The lower the
number, the faster the connection between the two points.
Note: Some hosts are deliberately configured to not respond to ping requests. As
such, we suggest pinging two or three hosts when performing your ping test.
