I love the Router it works perfectly. And is cheaper than having 2 cable modems. So my brothers computer has the big monster cable modem and I have the wireless Router. Both computers are indeed lightning fast.
My computer with the Router came with a computer disk that downloads to the computer so your computer knows what to do with the Router, and also the computer guys from Bright House went into my computer settings and set it to receive the signal from the modem. There are certain numbers assigned to each account that needed to be applied to the computer so it can receive the signal. They hooked the whole thing up. I just watched. Those guys are good at what they do, very professional.
Great technology and my computer is faster than its ever been. Pages load in a second.
Here's what the Router looks like. I have it sitting on-top my computer:
