I have all three FiOS services. Verizon will provide you with a combination modem/router that is both wireless and has 5 ethernet ports. Thus you will be able to hardwired directly and/or wirelessly from your PC or TiVo. In my case the S2 is connected via a USB to ethernet adapter and my S3 is via a TiVo wireless adapter. The wireless function of the router is excellent since the signal is about 50% stronger than the Belkin wireless router that I previously had. The nice thing about the Verizon service is that all the components are supplied by them and thus they are fully compatible. My experience with Cablevision is that they supplied a Motorola modem, I had a Belkin router and they supplied SA CableCards that always seemed to be either defective or needing a firmware update. The Motorola components supplied by Verizon all have worked from day one.
