If it has an ethernet port you should use the ethernet port for maximum internet speed.
You can use it without the ethernet port assuming it offers wi-fi but that will not give you faster speed.

You can use a USB/Ethernet dongle and pick 10/100/1000 speeds to get whatever speed you are actually paying for via your ISP (they control the speed, not you).
I am using one since the ethernet port on my motherboard burned out YEARS ago. :)
While my ISP offers 1 gbit service, I opted for 300mb level --- it was half the price of full throat and WAY faster than any traffic throttled website(s) I visit on a regular basis.
