Hi I am finding similar issues on Insider Preview 25236.100 (not sure if this was also the case on the same build as Nick as I have only just updgraded sufficient internet speed to observe this.
Also have done the following:
In Device manager for the NIC, I have made the following ChangesEnergy-Efficient Ethernet to Disable
Gigabit Lite to Disable
Green Ethernet to Disable
Power saving Mode to Disable
Speed and Duplex to 1Gbps full Duplex
Nick one point of note is that I was getting on LAN and WiFi 16Mb download on a router that has 200Mb available (confirmed on other devices over WiFi)
I disabled IPv6 and this went up to 40Mb - worth trying would be interested to see of you get a difference.
