No TCP connection established after ARP request

Hi,


I hope this is not too much off topic, but my iPhone app tries to establish a TCP connection over Wifi. I noticed that sometimes (about 30% of the attempts), a connection is refused. I do see an ARP request, but there is no TCP SYN packet following after the answer. Is this a bug in iOS? How can I make sure that the ARP request is not needed? Or can I automatically resend the TCP SYN packet? Thanks in advance for any ideas.

Kind regards,

Remco Poelstra
