Connect to two different networks at the same time

I want to know if it's possible to use a USB wireless modem and at the same time be connected to a wireless router with the result of increasing my internet speed. I have them both connected at the moment but it seems like only the USB modem is being used. How can I set up my laptop so that it uses them both and makes my connection faster?

It's not possible to do what you want.
