I want to connect to internet using Ethernet-to-USB adapter because my laptop doesn’t have ethernet port. My wifi is working fine, I just want to see if I can get better speed with the ethernet adapter.
Problem is it doesn’t show anything when I plugged the adapter.
Is there anything I need to download/configure for this?
Usually, plugging a USB2 device into a USB3 port “just works”. Occasionally, however, you run into a combo where it refuses to see the device (certain iPod models have this issue, as well). At that point, you can either plug the device into a USB2 port or into a USB2 hub plugged into the USB3 port.
Also, if you are concerned about transfer speeds, I’d pick up a USB3 Ethernet adapter or a USB3 hub containing an Ethernet port.
That is mostly true - if both host and device support that protocol.
What speed do you expect? Cheap usb-ethernet connectors normally support 100 Mbps connection and USB 2.0 can go up to 480 Mbps. For full gigabit ethernet you would need USB 3 and higher.
