We have a small house in the countryside and there is no fixed broadband, so we had a mobile flatrate first, and for 2 people with 2 computers it was too slow, so now we have 2 flatrates for 2 client machines. So I pay 2 flatrates and have double bandwith theoretically. There is a local network in the house that connects everything.

But when I am alone I wonder how I can use both connections at the same time.

I want to build a solution where I can browse the web and page requests are spread between the 2 connections.

I imagine there are expensive routers who can split the traffic between 2 lines. But is there a good way to do it with linux?

The solution I am looking for will split the requests already for one page (multiple images, css files, javascrfipt files) between the two lines.
