Modems

Expert Review Analysis

The NETGEAR CM600-100NAS is a DOCSIS 3.0 cable modem offering up to 960 Mbps download and 320 Mbps upload with a single Gigabit Ethernet port. It provides reliable sub‑gigabit performance for streaming and gaming while eliminating monthly rental fees, but is limited by its older DOCSIS standard and lack of built‑in Wi‑Fi.

✓ Best for: Households with cable internet plans up to 960 Mbps that need a reliable, owned modem for a single wired connection to a router—ideal for gamers, streamers, and users looking to avoid ISP rental fees on sub‑gigabit plans.✗ Not ideal for: Users on true gigabit or higher plans, those who require built‑in Wi‑Fi, multi‑device Ethernet connections, or bundled voice/TV/phone services, as the modem’s DOCSIS 3.0 limit and single port restrict those scenarios.

Pros

✓Supports up to 960 Mbps download and 320 Mbps upload, delivering sub‑gigabit speeds ideal for HD streaming and online gaming.
✓Includes a Gigabit Ethernet LAN port for fast wired connections and easy integration with a separate router.

Easy CD‑less installation with auto‑sensing Ethernet port and IPv6 support, simplifying setup for most cable ISPs.

✓DOCSIS 3.0 24‑downstream/8‑upstream channel bonding provides stable performance and backward compatibility with DOCSIS 2.0 devices.

✓No monthly rental fees when owned, offering cost savings over ISP‑provided modem rentals.

Cons

✗Limited to DOCSIS 3.0, cannot achieve true gigabit speeds offered by newer DOCSIS 3.1 modems.
✗Only a single Ethernet port, requiring an additional router for Wi‑Fi or multiple wired devices.
✗Actual speeds depend on ISP provisioning and may be capped below the theoretical 960 Mbps maximum.
✗Not compatible with bundled voice, TV, or phone services, restricting use for some ISP packages.
✗Fixed upright stand design can be inconvenient for flat placement and requires a Torx screw to remove.

From Expert Reviews

Praised by Experts

✓Dong Knows Tech highlighted its ability to consistently deliver near‑gigabit speeds (around 700 Mbps) on sub‑gigabit plans with simple, reliable performance.
✓Netgear datasheet emphasizes 24× faster channel bonding than DOCSIS 2.0, enabling efficient HD streaming and gaming.
✓Retail specs note blazing‑fast access and broad compatibility, positioning it as a cost‑effective owned modem alternative.

Criticized by Experts

✗Professional reviewers note that DOCSIS 3.0 limits the modem below true gigabit, recommending DOCSIS 3.1 models like Motorola MB8600 for full‑gigabit plans.
✗Single Ethernet port means users must purchase a separate router for Wi‑Fi or multiple devices, reducing convenience.
✗Lack of WAN link aggregation and no built‑in wireless may be a drawback for users seeking advanced networking features.

From User Reviews

Users Love

✓Users report consistent high speeds and stability across ISPs such as Xfinity, Spectrum, Cox, and RCN, making it reliable for gaming and streaming.
✓Easy self‑activation and out‑of‑the‑box operation with separate routers are praised for hassle‑free setup.
✓Many users find it more reliable than the Arris SB6190, especially on 600 Mbps+ plans.

Users Complain About

✗Users complain that a separate router is required for Wi‑Fi because the modem only provides one Ethernet port.
✗The fixed upright stand for cooling is seen as inconvenient for flat placement and requires a Torx screw to remove.
✗Some users note that the modem does not support bundled voice/TV/phone services, limiting its use with certain ISP bundles.

Expert Opinion

Professional reviewers consider the CM600 an excellent sub‑gigabit cable modem that delivers reliable near‑gigabit performance with simple setup, but they caution that its DOCSIS 3.0 architecture falls short of true gigabit capabilities, recommending DOCSIS 3.1 alternatives for future‑proofing. The single Ethernet port and lack of advanced features are also noted as limitations.

What Users Say

Everyday users appreciate the modem’s consistent high speeds, easy activation, and cost savings over rental fees, often citing better stability than comparable models. Common complaints focus on the need for an additional router, the upright stand design, and incompatibility with bundled voice services.

Common Complaints

The most recurring issues are the requirement for a separate router due to only one Ethernet port, the inconvenient upright stand that needs a Torx screw to remove, and the inability to support bundled voice or higher‑speed gigabit plans.

How It Compares

vs. Arris SB6190

Advantages

✓CM600 is reported by users to be more stable on sub‑gigabit plans than the SB6190.

Disadvantages

✗SB6190 offers more downstream channels theoretically, but CM600’s simplicity and lower cost are preferred by some.

Choose the CM600 for reliable sub‑gigabit performance and lower price; opt for the SB6190 if you need higher theoretical channel bonding.

vs. Motorola MB8600

Advantages

✓CM600 is cheaper and easier to set up for sub‑gigabit plans.

Disadvantages

✗MB8600’s DOCSIS 3.1 support and 2.5 Gbps Ethernet make it superior for true gigabit+ internet speeds.

Select the MB8600 for future‑proof gigabit or higher plans; stick with the CM600 if you only need up to 960 Mbps and want a budget solution.
