It does not work with Time Warner Cable System

on 5/16/2014

It does not work with Time Warner Cable System in Enterprise, AL. I had read other reviews that said it worked with Time Warner so I bought it for the price and performance specs. It did not work but my return of the item was handled outstandingly.
