Need help w/ USB Ethernet adapter

[Cronald]

I have a Windows 10 laptop set up as a HTPC. I purchased a USB gigabit ethernet adapter as it lacks an RJ45 connector. I am averaging 200+ Mb/s on my desktop computer, which is also on windows 10. It is plugged into an identical ethernet cable connected to the same router. I have a Peppermint linux live USB and I get identical speeds to the desktop computer on the laptop with that. In Windows 10, I'm getting 35Mb/s average on the laptop. How can I resolve this??

What's the adapter you got exactly? Is it USB3, and plugged into a USB3 port? Those numbers suggest it's running at USB2 speeds.

 

Alternatively where does the data you're transferring actually come from? Something fast enough to give more?

Yep, USB 3 adapter.  I tested the adapter on my old (beat to hell) laptop running Peppermint, and got the same results that I did in the peppermint live CD.  I even plugged it into the USB 2 port on that old laptop and got 150Mb/s average. 

 

I am getting these figures directly from Google's speed test.  I am doing local network data transfers (HDD hooked up to the HTPC, Windows drive sharing activated so I can transfer data from the desktop, however that's not an issue as it sits.

 

Here's the actual adapter:
