Best Cable Modems of 2026

The MB8600 has been on sale long enough that very little about it is still a mystery, and that's most of the appeal. It's a DOCSIS 3.1 modem rated for plans up to a gigabit, with one gigabit Ethernet port, a two-year manufacturer warranty, and active queue management — a latency feature that keeps the connection responsive while someone saturates the uplink with a backup or a big upload. AQM never makes it onto the box, and you notice the moment it's missing.

One gigabit port is the catch. On a 1.2 Gbps or 2 Gbps plan the router never sees more than that jack can pass, so you're paying for speed that stops at the modem. For the 500 Mbps and 1 Gbps households that still make up most of the country, that ceiling never comes up. The awkward part is the price: it sits close to our top pick, which throws in a 2.5 Gbps port and next-gen upstream certification for the same kind of money.

Cool running is a real advantage in a category where heat is where failures start, and this one stays noticeably cooler than most of the field. Nothing about it is exciting — a black box with status lights on the front, a provision in minutes, and then you stop thinking about it. That is the whole job, done.

Netgear's app does more than most: it walks you through activation, runs a speed test, and pushes firmware updates without making you hunt through a browser menu. On a device that's otherwise a power jack and a coax connector, that hand-holding is a genuine convenience, and it's the smoothest setup in this group.

The hardware is where the trade-off lives. The CM2500 is rated to 2 Gbps downstream, but it gets there by bonding two gigabit ports rather than by giving you a 2.5 Gbps jack. Link aggregation is supported by some routers and mesh systems and ignored by plenty of others, so the second port is worth nothing if yours doesn't do it. Check that before you order, because otherwise you've bought a gigabit modem with a spare jack and a 2 Gbps label.

Everything else is solid. It's meaningfully cheaper than our top pick, activation is quick, and 2 Gbps is more than most households will use for years. The one-year warranty is the shortest of any modem here, though, and that coverage gap is what keeps it behind the S34 for us.

The price is the argument, and it's a good one. This is the least expensive modem here, rated for cable plans up to 900 Mbps, with a gigabit Ethernet port and a two-year warranty. For a household on a 300 or 500 Mbps plan, we think it's the obvious buy: nothing it does will hold you back, and the savings are better spent on the router that actually determines your Wi-Fi.

DOCSIS 3.0 is the trade. Every major cable provider still accepts it, and 900 Mbps is more than most plans deliver, but there's no headroom if your provider bumps you to a gig-plus tier — you'd be shopping again inside a year. The full-band capture tuner is the detail worth knowing about: it reads the whole downstream band at once, which helps hold speeds on a crowded neighborhood node. At this price, that's a better use of silicon than a bigger channel count on the box.

Two years of coverage is the quiet win, and it's the reason we're comfortable recommending a budget modem: it carries you past the point where cheap units typically fail. No other modem here pairs that warranty with a price anywhere near this low, and for a sub-gig household that's the whole decision.

At 6.73 inches square and about 2 inches tall, this is the smallest modem here, and small is most of what a modem needs to be. It sits on a shelf edge, the white case reads clearly against dark furniture, and the front status lights are easy to check from across a room.

The specifications are deliberately modest. DOCSIS 3.1 with a 1 Gbps downstream rating, 350 Mbps upstream, a single gigabit Ethernet port, no Wi-Fi and no voice. The upstream figure is the useful part — it's well above the DOCSIS 3.0 modems here, and upload tiers are the thing providers keep raising. The single port means everything downstream goes through your router, with no spare jack for a wired device.

Our read: this is the modem for someone on a 1 Gbps plan who wants DOCSIS 3.1 and already likes their router, without paying multi-gig prices. What holds it back is the record — dropped connections and units that quit after a few months both show up — plus a warranty term Hitron doesn't publish on the listing, which is worth confirming before you order. Under a gigabit, the Motorola MB7621 is cheaper and just as capable.

Three Ethernet ports is more than any other modem here offers, and one of them is a 2.5 Gbps jack. Add a 2.5 Gbps downstream rating and a 1 Gbps upstream rating and you have the most capable port layout in the group: a multi-gig plan into the router, plus two gigabit jacks for link aggregation on hardware that supports it.

Setup runs through the same Nighthawk app as the CM2500, still the most helpful flow here, and the box itself is a chunky 2.5-pound unit rather than something you tuck behind a router. Coverage is the short end of what's on offer: one year, where Arris and Motorola give two.

Two things keep it behind the S34 for us. The first is value — the premium over the other multi-gig picks is real, and the extra ports only pay off on a router that can use them. The second is the failure pattern: in some units every status light blinks in unison and the connection never comes back, and provisioning at the top tier is a question mark on at least one provider. Confirm it's on your provider's approved list for your exact plan before it ships.
