Cablevision doubles speed of Wi-Fi network, fires up 100 Mbps DOCSIS 3.0, too: The New York/New Jersey/Connecticut cable systems operator is now promising up to 3 Mbps (instead of 1.5 Mbps) over its Wi-Fi network, which is exclusively available to its broadband customer. The company also wants bragging rights, with a 101 Mbps/15 Mbps top-tier DOCSIS 3.0 broadband service for $100 per month. Verizon, Comcast, and others top out at 50 Mbps downstream (at the moment) for $30 to $60 more; many providers aren't offering rates above 20 or 30 Mbps.
