How to combine the speed of two modems?

Question

WiFi

How to combine the speed of 2 ADSL modems in win7 for downloading uTorrent. I connect one modem to the laptop via a cable, the second via WiFi from neighbors (a simple password).
A couple of times it happened by accident, connected to WiFi then inserted the cable and the speed was 2 times higher. But I can’t find exactly what actions to do so that it always works when I want.

Answer 1

How to combine the speed of two modems?

Without any additional equipment.
In principle, it is possible with software, but for windows the choice is not rich.
It's easier to buy Mikrotik and set up round-robin. Surfing the Internet will fail, authorization will fall off, but the torrent will work with both providers.

It seemed to you. It doesn't happen by chance.

You need to turn on the torrent, when wi-fi is connected it will create routes through the wi-fi gateway, let it pick up speed, then connect the cable so that the torrent builds another part of the routes through the second gateway. If you did not change the interface metrics, then the cable will become the channel for the Internet and the torrent will increase by the size of the cable channel. This will need to be done with each new download, and the use of the Wi-Fi channel will decrease with disconnected seeds, not recovering back.
It is worth finding software for balancing on wines, it is. You can also make a virtual machine, install PfSense or RouterOS in it, forward your network cards there, and pick up the Internet via a virtual interface. Not necessarily RoundRobin, because RouterOS can create new connections to the least utilized channel

Former Connectify Dispatch, now Speedify.
Connectify Dispatch: Consolidates all available internet connections into one wide channel.

Here is a solution using Windows, everything is described in detail in the video - download the torrent from 2 connections or more, although it is clumsily described, but it works https://youtu.be/Er4DVvwEcfk
