Windows

I have strange problem.

On my computer some application works with one internet connection ( ISP ) and some through other internet connection ( ISP )

This problem has started since last few days. 

I flush dns and did most common solutions found on net like changing TCP/IP but nothing worked.

Is there any way to get rid off from this error ?

Or is there any way we can combine BOTH wireless internet connection in one PC and make some settings that which application works with which internet connection ( ISP )

I have 2 wireless internet dongles and I have 2 dongles which I can attach to my PC to connect to this internet dongles.

I read about Bridge connection and i did it but this didn't solved the error. May be because I am not able to make settings which application uses which internet connection

PLEASE NOTE, I am not having problem in browsing website. I am having PROBLEM in installed application, like stock market trading software.

I tried disabling antivirus also, but nothing worked.
