I want to buy a cable modem and stop paying a leasing fee. My current modem, provided by Time Warner, is a Surfboard SB5100. In order to anticipate future upgrades, I'm thinking I should get a better modem, even if it won't change current performance.
The SB5101 is the current equivalent model. There is also the SB6121 and SB6141. The latter has the following description:
Internet download speeds up to 343 Mbps and upload speeds up to 131 Mbps based on your Cable provider service
Gigabit port to connect with router or computer
Docsis 3.0 with backward compatibility with 2.0 and 1.x
The SB5101 says:
When connected to a DOCSIS 2.0 cable network, capable of up to 30 Mbps upstream capacity
My question: any advice on any of this? I currently have 20Mbps service.
