I am planning on connecting my gaming PC to the internet via ethernet cable for more reliable and faster connection. There is an ethernet port (Cat5) in my wall, and another ethernet port next to my modem. The ethernet port next to my modem has a wire coming out from the port into the modem. I am guessing that I have to buy a wired network adapter for my PC and then get an ethernet cable, plug it into the adapter and then the ethernet port in my wall? If so, is this a good wired network adapter - http://www.amazon.com/dp/B001CY0P7G/?tag=pcpapi-20 ? Plz help! Thanks! (if it is any help I live in a house, not an apartment)
