I am trying to connect to an ec2 instance via a Java SSH client. The error I am getting is Connection Time out. Now the problem is either with

  1. The Modem - DWM-156 HSUPA 3.75G USB ADAPTER (I am using a wireless dongle to connect to internet) or
  2. ISP

The reason for my suspecting the error in one of these is because I can connect to the same ec2 instance via a wired internet connection with Siemens Modem.

My Question

Why I am not to connect to an ec2 instance over a wireless internet connection?

it could be the poor connectivity. you might want to try mosh in this case.

not sure if there is an equivalent java ssh client, however, that will be more tolerant of lost packets, high jitter, etc.

I have a PC with Windows 7, looks like mosh doen't run on Windows. – Gaurav Agarwal Jun 22 '12 at 19:07
it runs under cygwin, though it may not be natively. – johnshen64 Jun 22 '12 at 20:01
