A:Answer No, this product does not have an Ethernet port.
However, there are converter cables that you can buy; the cable plugs into your computer's USB port, and then you plug your Ethernet cable from your modem or router into the other side of the converter cable. I recently purchased one of these from here, I *think* it was the Belkin below -- and it worked flawlessly out of the box on my Mac, but it should work fine on any OS.
BestBuy's website list one on sale for $19.99 here (and 80 people's averaged ratings on it are 4.6 out of 5):
