I'm a noob when it comes to everything tech so just wanted to ask more experienced individuals if this cable will work and if its a good cable in general. http://www.showmecables.com/viewitem.asp?idProduct=4013

almost all ethernet cables will work.  you could look into getting cat6 cables which allow more bandwidth, not that you'd need that bandwidth but they didn't cost anymore more when I bought them.
 
you could probably get a better price on another site.

really any Ethernet cable will work for internet. i would say go to walmart or best buy to buy a Ethernet cable. my friend bought a long one for like 8 dollars.
