LAN Throughput Problems

[QueK9]

I have everything connected and updated but my read and write speeds are atrocious.

I have a gigabit LAN and typically see speeds between 80-100 mb/s but with the Targus Ethernet connection I am only getting 3-10 mb/s read and write speeds.

This is quite perplexing because Under the adapter settings it appears that I am connected at 1.0 Gbps. Hopefully there is a simple fix for this.

Setup includes:

Dlink gigaswitch, cat5e wiring, dell xps 12, windows home server.

Attached are my logs.
