Gigabit internet is here. Although gigabit internet may not be available everywhere, by the end of this year, many cities will be covered by it. However, your existing modem will not work with gigabit internet. However, getting the best gigabit Docsis 3.1 modem requires extensive research and testing. And we have done the hard part for you and created a list of best gigabit Docsis 3.1 modems.
To make the latest gigabit fiber internet to work, you need a DOCSIS 3.1 gigabit cable modem. DOCSIS 3.1 has ten times more speed than DOCSIS 3.0.

What does Docsis 3.1 mean?
Docsis means Data Over Cable Service Interface Specification. It is a standard for transferring data over the cable system. And Docsis 3.1 is a new generation of technology made for high-speed connections. It can support data transfer up to 10 gigabits per second downstream and 1 gigabit per second upstream over cable, which was only possible over the fiber-optic network.
Is a Docsis 3.1 modem worth it?
If you have a gigabit internet plan, then Docsis 3.1 modem is the best option. Even if you don't have a gigabit internet plan, it is still the best option since many ISP declared DOCSIS 3.0 end of life. It means some ISP may not allow DOCSIS 3.0 modem activation for new accounts. And some DOCSIS 3.0 modems cost the same as DOCSIS 3.1 modems, so there are no financial benefits to not using a DOCSIS 3.1 modem.
Difference between Docsis 3.0 and 3.1 modem?
The differences between 3.0 and 3.1 comes down to speed, and the ability to use simultaneous channels. Docsis 3.1 comes with 10Gbps of download speed, 1Gbps of upload speed, and 1.89 Gbps per 192 MHz channel. However, Docsis 3.0 is only capable of 200 Mbps upload, 1 Gbps of download speed, and only 42.88 Mbps per 6 MHz channel. In short Docsis 3.1 has much higher speed, throughput, and uses data spectrum more efficiently than Docsis 3.0.
