Wired vs Wireless for Mi and NP

using my N9 tablet, using wireless AC I got a FASTER speedtest than I did using my computer connected directly to my router. The difference is wireless AC is gigabit wifi and my N9 supports it. My computer doesn’t have a gigabit network interface.

When you use a USB network interface on a NP or a Mi, would it REALLY be faster than the native 802.11AC that they both support, providing of course your router supports it.

Well is the USB Ethernet dongle for the Mi 100 Mbps or 1000 Mbps interface?

Being as how the USB interface is 2.0, I believe it is limited to 100 Mbps. There is a USB 3 interface for 1000 Mbps
