Was to install Virtualbox and 2 OSes. That gave us the Host OS plus 2. Each OS then could download a file via each ISP.
As to other ideas, I leave you to the web. Google up modem bonding, etc.
Hello everyone, I'm working on a project as intenship in a telecommunication firm and i'm trying to find a solution where i can connect 3 Dongle Internet Modems from 3 different ISPs in a windows PC, and then either choose to connect to one of the 3 networks to download or stream for example, OR, to use the 3 networks simultaneously to download, for example, 3 files each one with a different network. I think the solution will contain hardware and software developement but I need your help to solve this. Any suggestions are welcome, and thank you for any help.
