FAQ:

Q: What is the maximum downstream speed of a DOCSIS modem?

A: These international standards certify that the modem is ready to play nice with most cable providers like Comcast, Time Warner, Charter, and Cox. The current spec available today, DOCSIS 3.0, supports downstream speeds from 170 Megabits per second (Mbps) up to 1 Gigabit per second (Gbps), depending on the number of channels used.

Q: What’s special about DOCSIS 3.1?

A: The DOCSIS 3.1 release included the latest and greatest digital communication technologies such as Low-Density Parity-Check encoding and very high modulation orders, as well as more than 1 GHz of usable spectrum , that led to a significant increase in network speed and capacity.

Q: Which is the best cable modem?

A: – Write down your cable modem’s serial number and MAC address first. … – Return a rented cable modem to your ISP in person and get a receipt. … – Check the grade of any included Ethernet cable. Not all network cables are created equal, and sometimes the one that comes with hardware isn’t fast enough. …

Q: What is DOCSIS 3.1 necessary for?

A: If you’re lucky enough to live in an area that does offer speeds at or exceeding 1 Gbps and you subscribe to such a service, a DOCSIS 3.1 modem would be a requirement, not a suggestion.
