What is the ping command that is used to check how many packed has been dropped (to check quality of the line)?

That would be
ping google.com when it has finished you will get a report of how many packets were received and lost.

You are maybe looking for something like this:

ping google.com -n 500 -l 2000

Commented:
Or are you looking for something like this:

'netstat -s -p tcp'

The output should show some lines like this:
  Segments Received                   = 1679
  Segments Sent                       = 1617
  Segments Retransmitted              = 2

If Retransmitted is just a few percent of Sent, then you have a less poor quality. If Retransmitted were like 200, then you might have a quality issue.

The command "ping google.com -n 500 -l 2000" (return Request timed out.)

and netstat -s -p tcp is not sending packet to any destination,

No, the report after that ping should say something like this:

Ping statistics for 66.102.13.99:
    Packets: Sent = 500, Received = 500, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 4ms, Maximum = 12ms, Average = 8ms

I can ping google.com, but "ping google.com -n 500 -l 2000" (return Request timed out).  does this tells you the speed of your line?

Commented:
Hello,

I am sorry. -l is the packet size. 2000 would be 2000 bytes. Try a smaller number if you only get request timed out with that.

If you want to check your speed you could try one of these tests:
