Use both WiFi and Lan to speed up the download

In my office we have WiFi and RJ45 LAN coection to my laptop. Both works well individually. We do not use DHCP and hence I have configured two different static IPs for these interfaces. While I observed through tracert command that WiFi is reaching the Inteet through a different access provider than the LAN interface because WiFi uses a different gateway than the LAN. This made me to wonder whether I could benefit of downloading part from WiFi and part by LAN there by reducing the total download time.

Is there any means by which I can use both interfaces to reduce the download time?

I saw many posts in SU about using simultaneously but not does not cover the doubling of speed. My machine is x64 Windows 10 Pro and have admin rights.
