BlackBerry Forums Support Community - Trouble Making socket connection over wifi

Hi All,
I'm having problems making a socket connection over wifi to my desktop. I'm using a 8320, building with jde 4.2.1.41. This works perfectly on the emulator as usual.
Snippet of the code i'm using:

Code:

 String url = "socket://" + _host + ":" + _port + ";interface=wifi;deviceside=true;";

                        System.out.println("Connecting to  "+url);

                        StreamConnection sockClient = null;

                        sockClient = (StreamConnection) Connector.open(url, Connector.READ_WRITE);

                         System.out.println("Connected to "+url);

I've done a trace on the server and wireshark does not see the connection coming in. I can browse the internet using wifi from the device, it's just when the app runs it does not connect and blocks on the open call.
I've also tried using a SocketConnection instead of StreamConnection with no change in behaviour.
I've also tried removing deviceside=true and changing it to false, with no luck.
Any ideas and thanks ahead of time.
