Oh Yes, I went the whole hog. I rebuilt windows because there was an issue with the driver. Found a router ( just in case), pluged it in, configured windows for static IP 192.168.1.2 All OK.
Unpluged Nano held down the switch plugged in and solid blue light. The device was recognised by win. Then Nothing, I even went as far as plugging in a second ethernet to usb and pluged that into the router and the nano. I was on a last hope at that point. Spent around 2 hours with every combination both on Windows and Nano and Linux. I have another Nano and that works fine. So, so frustrating but I live in hope to see your video.
