#2
Best for: temporary solution users on DOCSIS 3.0-compatible ISPs
Motorola MB7621
from 4 sources$79.99as of Jul 7
▾Why it's ranked here

The Motorola MB7621 is a DOCSIS 3.0 cable modem that delivers reliable performance in the right ISP environment, offering speeds between 500 and 900 Mbps with stable connections and cooler operation compared to some competitors. However, it's not suitable for plans exceeding 700 Mbps and faces obsolescence as Spectrum plans to end support by October 2026. Wirecutter selected it as 'the best modem for most people' in 2019, but its limitations make it a temporary solution for users planning future upgrades.

Strengths
  • — Operates on DOCSIS 3.0 with 24 downstream and 8 upstream channel bonding
  • — Runs on a Broadcom chipset that runs cooler than some rivals
Watch-outs
  • — Not suitable for plans above 700 Mbps due to DOCSIS 3.0 protocol ceiling
  • — Spectrum is ending support for DOCSIS 3.0 modems on October 28, 2026

#3
Best for: multi-gigabit plan users needing reliable performance
Netgear CM2000V
from 4 sources$289.95as of Jul 1
▾Why it's ranked here

The Netgear CM2000 Nighthawk is a DOCSIS 3.1 cable modem supporting up to 2.5Gbps speeds, offering reliable performance for users with faster internet plans. Customer reviews are mixed, with some noting significant speed improvements over older models while others found it no better than the CM1200. The modem's setup is straightforward but ISP activation can be problematic. It's best suited for users with multi-gigabit internet plans rather than those on standard Gigabit connections. Reddit users and Crutchfield reviewers reported both positive and negative experiences, with the main complaint being the activation process with Comcast/Xfinity.

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
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

Motorola MB8600
#4
Best for: users upgrading to Gigabit plans who want higher speeds
Motorola MB8600
from 4 sources
▾Why it's ranked here

The Motorola MB8600 is a DOCSIS 3.1 cable modem offering up to 6Gbps speeds with a straightforward setup process. Reviewers noted its simple design and reliable performance, though some observed it runs hotter than competitors like the Arris SB8200 due to less effective cooling. It supports WAN Link Aggregation and works with major ISPs including Comcast Xfinity and Cox. This modem is ideal for users upgrading to Gigabit plans but may not suit those seeking premium build quality or minimal heat output.

Strengths
  • — Capable of DOCSIS 3.1 standard with 6Gbps top WAN speed
  • — Simple setup process with clear status lights
Watch-outs
  • — Uses less robust cooling design compared to Arris SB8200
  • — LED status lights can be too bright and require covering

Motorola MB8611
#5
Best for: high-speed wired connection users willing to accept firmware risks
Motorola MB8611
from 4 sources
▾Why it's ranked here

The Motorola MB8611 is a DOCSIS 3.1 modem offering fast internet speeds with a 2.5Gbps Ethernet port and support for up to 32 downstream and 8 upstream channels. Tech Reviews called it a great modem with backward compatibility and AQM for low-latency performance. However, some users have reported firmware-related stability issues, particularly with version 21.3.7, leading one user to switch to an Arris S34 after prolonged problems. It's approved for use with Comcast Xfinity, Cox, and Spectrum. This modem is ideal for users seeking high-speed internet but may not be suitable for those requiring voice capabilities or who experience firmware instability.

Strengths
  • — 2.5Gbps Ethernet port for high-speed wired connections
  • — Fast DOCSIS 3.1 speeds with support for 32 downstream and 8 upstream channels
Watch-outs
  • — No voice capabilities
  • — Has firmware issues reported by some users (specifically 21.3.7 firmware causing instability)

Netgear CM1100V
#6
Best for: users wanting future-proofing without business features
Netgear CM1100V
from 4 sources$179.99as of Jul 7
▾Why it's ranked here

The Netgear CM1100 is a DOCSIS 3.1 cable modem designed for retail distribution, particularly at Costco. While it features two Ethernet ports that enable Link Aggregation for speeds up to 2 Gbps with compatible routers, most home users will only utilize one port. Reviewers note it's a middle-ground option between the basic CM1000 and feature-rich CM1200, offering good value for those wanting future-proofing without the business features of the CM1200. However, the extra ports can confuse average users who don't understand they're for Link Aggregation or Multi-IP support rather than direct device connections.

Strengths
  • — Supports DOCSIS 3.1 standard for high-speed internet
  • — Includes two Ethernet ports for Link Aggregation capability
Watch-outs
  • — Only one Ethernet port can be used for standard home setups
  • — Requires specific router settings to utilize both Ethernet ports
