Hi everyone.

I am trying to write an application that sends (on a separate thread)
a file over TCP to a listening server in my laptop. After several
unsuccessful tries I've found - with the help of Wireshark - that the
Android device starts a retransmission of already acknowledged
segments, and then the server obviously starts sending duplicate
ACKs.

Some duplicates after, the connection seems to have been lost as some
ARP (Address Resolution Protocol) searches between client and server
happen. I've also found that LLC (Logical Link Control) also throws a
lot of "null LSAP individual" messages during the process but I'm not
quite sure this has to do with aforementioned TCP problem.

Has anyone any idea or maybe has suffered a similar problem? Any help
or clue will be very appreciated.
Thanks beforehand.
