That shows that your MyCloud is connected to your router via a gigabit ethernet link; the top LED would be yellow if it were 100megabit.
That’s a WiFi adaptor (802.11n) (with Bluetooth 4.0, too)…
I thought you had a WIRED connection from your computer to your router?
Your laptop spec says it has a gigabit wired Ethernet port.
Is you laptop connecting to your router via WiFi, or via Ethernet? It is possible to choose one or the other. On the right of the task bar, there will be some icons. One of them will be for the network connection. If you click on it, it will open up, and it should show either a wired network connection, or a WiFi network connection (for the latter, it will show signal strength and wifi network name).
My suspicion is that your laptop is connecting to the router via WiFi, not via the wired Ethernet port. Try disabling the wifi, and seeing if the laptop drops back to wired ethernet. Or turn off wifi on the router, and see if your laptop can still connect.
