Win10 or Linux Drivers for VM with Win10 Host and Unbuntu Guest

The guest connection cannot go through the router as it will then give the same IP address as the host (and the reason this is not desirable is unimportant). It needs to connect to a mobile WiFi 4G router. The VM will replace a separate laptop with this connection.

Yep. Good reason.
You've probably already seen these links:

I know people who do it, but they are very specific about the wifi USB device, since they need specific capabilities for their research.

In VirtualBox, if I specify "bridged networking" in the Network configuration rather than NAT, my VM gets an entirely different IP address when booted. Right now my Linux host has 192.168.100.58, and my Windows VM has 192.168.100.61. That's because the VM has an entirely different MAC address from the host, and thus my router's DHCP server gives it a different address. Because of that, I see no reason the same behavior would not apply to a Windows host and a Linux guest.

In "bridged" mode, the VM sits directly on the network the same way the host does.

Yep. The OP is trying to have Windows use 1 WAN connection and the VM guest running Ubuntu use a different WAN connection.
At least that is what I understand.

Yes, I realize that. But he seemed to be working under the misconception that the host and guest must have the same IP if they use the same interface.

That's not true for VirtualBox with bridged networking, and I suspect it's not true for other VM software either.
