Time Warner is the company offering cable TV and cable modem in my area. I only got cable modem through them, not cable TV (I have satellite). My question has to do with the splitter that they use. Once the coax cable was inside the house, the tech used a splitter with one input and two outputs. The input comes from the outside. One output goes to the cable modem and the other has this cap thingy that I can't seem to remove. It spins but it doesn't unscrew. Does anyone how to remove this? Do you know what I'm talking about?
