Dell Venue 11 Pro 7140 - Ethernet question

Hi, I have the Dell Venue Pro 11 7140 with the slim keyboard that comes standard. I would like to have an Ethernet port to increase my Internet speed while watching Slingbox content on the tablet. Can I simply use a USB to Ethernet adapter or do I have to download drivers or purchase some other hardware? Also, does the keyboard that has the internal battery have a Ethernet port. I was thinking about purchasing one. If it has the Ethernet port built in, that would give me another reason to purchase one.
Thanks in advance.
