Is thre a setting for slow Ethernet connections?

I am trying to connect to one of the online controllers at Delta and keep getting the message:

Communication with Controller1 was lost. No Controller was detected.

I suspect this is because my connection to the internet is through a 4G cell phone and the other end sees this slowness as a dropped connection.

Is there a setting somewhere that would let me tell the controller that I have a slow connection and it should wait longer before timing out?

Go to tools->options->Communications->Ethernet Timeouts section and change default to remote. It lengthens the timeouts considerably. If that doesn’t work try the custom time outs.
