[h=5]Time warner wants to charge me $4/month for a modem rental fee. I can buy my own modem from their supported list which cost $60-$100. They are all docsis 3.0 modems. I currently have one they gave me that is docsis 2.0. I'm paying for about 20 Mbps. I can buy a docsis 2.0 modem for $15. At 20Mbps do I actually need docsis 3.0?[/h]
