Depends what you mean. There is no physical way to get 2 pipes to become 1 pipe. There is a way to balance loads on them though. You will need to get more advanced equipment besides a normal home router. I dont give a shit what any article says. It is not possible to merge them into one. It is possible to make it look like you did on a piece of software. But it not technically possible. This should help though.
