Our take on the Netgear CM2500-100NAS

The Netgear CM2500 is a DOCSIS 3.1 cable modem rated for up to 2 Gbps down and 1 Gbps up, with 32x8 channel bonding and two Gigabit Ethernet ports. It is a modem only, so it needs a separate router or mesh system for Wi-Fi. The two LAN ports let you feed a router and one wired device without a switch, which most single-port modems cannot do. It suits households on gigabit or multi-gig cable tiers who want to own their modem instead of renting one.

Pros
  • DOCSIS 3.1 with 32x8 bonding handles multi-gig cable tiers
  • Two Gigabit LAN ports, one more than most rivals
  • Up to 2 Gbps down and 1 Gbps up
  • Compact footprint at 8.2 inches tall and about a pound
  • Works with major US cable providers
Cons
  • No built-in Wi-Fi; a router is required
  • No phone port or voice support
  • Only 1 Gbps on each LAN port, so a single port can't pass 2 Gbps
  • Not compatible with fiber, DSL or satellite service

Questions and answers

Do I need a router with the CM2500?
Yes. It is a modem only with no Wi-Fi, so you connect a router or mesh system to one of its Ethernet ports.
Will it work with my cable provider?
It is built for DOCSIS 3.1 cable networks, which covers most major US cable ISPs. Check your provider's approved modem list before buying.
Can it handle a 2 Gbps plan?
The modem is rated to 2 Gbps down, but each LAN port tops out at 1 Gbps. Getting the full 2 Gbps to one device needs link aggregation or a router that supports it.
How is it different from the CM2000?
Both are DOCSIS 3.1 modems. The CM2500 adds a second Gigabit LAN port and is rated higher on upload, at up to 1 Gbps.
What is in the box?
The modem, a power adapter and an Ethernet cable. A coax cable is not included.
Does it support phone service?
No. It has no voice port, so it will not work with a cable provider's landline package.
