    Hey brooks79,
    What's the Realtek model ?
    If you haven't already, I'd search on MS Catalog for your Realtek model and try an older driver.

    You don't use duplex that sends and receives at the same time and most domestic routers can't cope with it so it slows it down. What is your MTU set to on router and PC?

    haha, finally found a setting for my specific Ethernet board was set improperly to auto select speed... Changed to 100mbps full duplex and my problems are gone... Yeah. I knew it was a setting somewhere deep within Windows 10..

    and it worked for a second and then back to slow Ethernet speeds...
    Try this, Windows always tries to auto-something, the less optimizations are involved, the better.

    Windows does not update Realtek LAN driver automatically, the latest version was just released.

    The solution that worked for me was to not only install the latest driver from Realtek, but to also physically unplug/re-plug the UTP cable after that. Simply changing the Realtek PCIe GBE Family adapter's "Speed & duplex" (under the Advanced tab in the Properties pane) from its default setting of "Auto negotiate" to "1.0 Gbit Full duplex" did not remedy anything so I changed it back to its default setting. In Windows PowerShell you can find out what the LinkSpeed of the adapter has been set to by typing get-netadapter and hitting on on Enter. Mine was set to 100 Mbps before I unplugged/re-plugged, and it changed to 1 Gbps after that.
