Netgear Cable Modem

I'm looking at buying my own cable modem since latest xFinity modem/router cable has issues. The Netgear CM1000 cable modem has - Only DOCSIS 3.1 modem  box enable 1 gbps cable internet service plans

I have a dumb question. If my Comcast Extreme Pro+ Internet speed plan is over 1 gbps will this modem cap my speed at 1 gbps?

Yes. It has only a gigabit ethernet port. You'll get only around 940 due to the inherent ethernet overhead. Comcast's Gigabit speed tier now offers 1200 Mbps advertised download speed (posters here are reporting that they are getting 1400 to 1500 speeds due to Comcast's 20% speed over-provisioning). If you want to be able to get over gigabit speeds, you'll need to use a modem that has 2.5 gigabit ethernet ports such as a Motorola MB8611, Arris S33, or a Netgear Nighthawk CM2000.

Quite welcome ! 🙂 BTW, there are other methods such LAG / LACP (Link Aggregation), and dual WAN. You can Google them for more info if you wish.
