With reference to the above code: line 9 gives the TCP3210 error -
Connection verification statistics: 0 of 5 successful (0 %). And yet line 13 connects. 

Ping & FTP are actually two different types of IP communications.

Ping uses ICMP (http://en.wikipedia.org/wiki/ICMP) while FTP uses TCP (http://en.wikipedia.org/wiki/Transmission_Control_Protocol).

Depending on the equipment, ping may be blocked (it's quite common for ping to be blocked on consumer grade routers, like Linksys).
