You can test your speed here: http://www.speakeasy.net/speedtest/ With cable you should have 20-30mbps, depending on your package. I suggest a dual band router, either the new "AC" standard or the previous "N". My speed is 35mbps on a wired connection. With my previous "B/G" standard router I would get ~6mbps on wireless devices (phones, laptops). Now with the Asus dual band N router I get 28mbps on wireless devices, definitely worth the upgrade. My Tivos use the wireless as well, but I will probably be hard wiring them, as there is occasional stuttering if you stream an HD program from one to the other.
