user41513: I setup an Antminer S9 using this document: (Link to document).
And I configured connection to antpool.com using this guideline: (Link to guideline).
So, I filled out the fields as follows:
Pool 1:

URL: stratum+tcp://stratum.antpool.com:3333

Worker: MySubAccountNameInAntpool.com.mywork

etc ...

Pool 2:  stratum+tcp://stratum.antpool.com:443
Pool 3: stratum+tcp://stratum.antpool.com:25 

And when I PING to antpool.com, no packet is lost as follows:

However, when I see Miner Status, there is no information ! (as follows:)

Also, my hash rate in my dashboard in www.antpool.com is zero !

What is the problem?
(If you need any further information, please let me know.)

user41513: I found the problem. In fact, although the PING to Antpool.com was successful; however, the network used a proxy causing problem of connecting successfully to Antpool.com. So, after changing the network I could see the hash rate in my dashboard.
