I just recently purchased a laptop and have no need for my desktop. I would like to connect my current modem and router to the TV. Can anyone tell me what I need to do? I've read that I can use a splitter and have one cable going to the DVR and the other to the modem, is this correct?
Your router should have multiple ports. Most have at least 4 wired. Plus, if it supports wireless, you can have that, too.
For your TV, if it supports wireless, you should be able to connect to your router. Otherwise, you can run an Ethernet cable to it. If it's too hard to run a cable, and the TV doesn't support wireless (or like some Sony's, it's an expensive USB receiver), you can buy a 'gaming adapter' that is little more than a wireless receiver with an Ethernet port. Typically cheaper than the dongle. (And I should mention that Sony devices will ONLY recgognize that special Sony USB receiver, not generic USB receivers.)
