DOCSIS 3.1 is the fastest cable modem standard, supporting Internet speeds of many gigabits per second. Actual speeds depend on your cable modem service speed, this modem’s 2.5 Gigabits per second Ethernet port speed, and the speed of the devices sending data through this cable modem.
Even if you don’t have DOCSIS 3.1 service now, you can benefit from the 32x8 DOCSIS 3.0 capability that’s also built into this cable modem. This is the fastest DOCSIS 3.0 capability available.
