I see a lot of people asking how to do it, so I might as well write this in the first post:
Condition 1: You need two broadbands (wired 1 + wired 2; wired 1 + wireless 2; wireless 1 + wireless 2 (haven’t tried it, but it should be possible))
Condition 2: The computer network card is connected to the router instead of the ADSL modem, and routing dialing is used instead of software dialing. I am not in a position to test the direct ADSL connection (the residential broadband is not ADSL).
Condition three: Both lines ensure that any broadband can be connected to the computer normally when connected to the computer at the same time. When connected at the same time, the system will display multiple networks. If both lines cannot be connected to the Internet at the same time, please check whether there are any errors in your settings. The test is to connect two broadbands at the same time under Windows 7 without any other settings.
Condition 4: The software "IGRS Anycom 5" is not necessarily required. I tested it myself and found that whether or not this software is installed under Windows 7 will not affect the broadband overlay. Other operating systems have been tested unconditionally.
Condition 5: Broadband overlay is effective for multi-threaded downloads. Single-thread operation has no broadband overlay effect. However, it is still effective for web operations based on P2P, such as Xunlei Kankan.
Condition six: Multi-threaded downloading. If you find that only one of the broadbands has traffic (use the system's task manager to check), then please disable this network card or unplug the network cable. Usually the traffic will automatically redirect to your other network card or another broadband. After seeing that there is traffic and is basically stable, enable the broadband that you unplugged the network cable or disabled the network card before. Usually both network cards will have traffic, and broadband superposition is achieved.
In fact, it is very simple, but in order to understand clearly, let me list one, two, and three... I hope people who understand will not find it too verbose.
