The Netgear CM1000 is a DOCSIS 3.1 cable modem that holds Gigabit speeds reliably, which makes it a straightforward upgrade from an older unit. Reviews consistently mention how easy it is to set up, how well it holds up, and how much faster it is than earlier models like the CM500 and CM600. Customer feedback reports compatibility with major ISPs including Comcast Xfinity and strong performance on 1Gbps plans. Complaints are minor: no coaxial cable in the box and a somewhat flimsy base. It's a common recommendation for anyone trying to stop renting ISP equipment.

Strengths
  • — Excellent performance with Gigabit-class internet plans
  • — Reliable and durable build quality
  • — Easy setup process with quick activation via ISP
Watch-outs
  • — Does not come with a coaxial cable
  • — Base is described as flimsy and modem can topple easily

NETGEAR Nighthawk CM2000
Ranked #4 in Best Standalone DOCSIS 3.1 Cable Modems
NETGEAR Nighthawk CM2000
1 source$249.99as of Jul 31

The Netgear CM2000 Nighthawk is a DOCSIS 3.1 cable modem rated to 2.5Gbps, which suits people on faster internet plans. Customer reviews split: some report a real speed jump over older models, others say it performs no better than the CM1200. Setup itself is straightforward, but getting the ISP to activate it can be a fight. Reddit users and Crutchfield reviewers landed on both sides, with the Comcast/Xfinity activation process drawing most of the complaints. It makes sense on a multi-gigabit plan and less so on a standard Gigabit connection.

Strengths
  • — Supports DOCSIS 3.1 technology for up to 2.5Gbps broadband speeds
  • — Easy setup process with standard web interface accessible at 192.168.100.1
  • — Compact design with clear status lights for troubleshooting
Watch-outs
  • — Does not provide noticeable speed improvements over older CM1200 model for some users
  • — Requires ISP activation which can be problematic and time-consuming
