So I got a new ASUS ZenBoon a month ago and I just got a USB to Ethernet adapter and wanted to test the connection speeds so I went to the SpeedTest website and did several tests with the adapter and via Wi-Fi and what surprised me is that the speeds were exactly the same for both USB to Ethernet (both thru 2.0 and 3.0) and Wireless.
I even went to SpeedTest on my PC — which is connected directly thru Ethernet without any USB adapters — and the speed was again exactly the same. I did the same tests with the Ethernet cables connected directly to the network without going through the router and I didn’t see any change.
All speeds are about 49 and 18 Mbps for download and upload respectively. So my question is, is there any substantial difference between Wi-Fi and USB to Ethernet specifically?
