DOCSIS

To get the best gigabit modem available today, make sure to check whether it supports the latest DOCSIS 3.0 and 3.1 protocols. It will help you avoid future upgrades. Besides, you need to check if it’s compatible with your devices.

Channels

If a modem has more channels, it can guarantee superior Internet speed and great accuracy. I recommend opting for a gigabit Internet modem offering from 8x4 to 32x8 bandwidth channels.

Providers

Not any modem is compatible with multiple Internet service providers. Thus, I recommend you to check whether a modem for gigabit Internet is supported by your ISP.

Security

This is an essential moment to take into consideration. The latest WPA2 encryption ensures that your connection will be pretty safe. Although it won’t be fully secure, it is the best and the most advanced technology available today for router security.
