Best Modem for 300mbps – Whether you’re currently (or always) working from home or just playing your way through a Game Pass subscription, high-speed internet is crucial. If you notice your connection becoming less reliable and download times lagging, it usually means you need to update either your modem or router.
For a new, powerful router, look here. Should it be the modem that’s failing, consider one of these great models with high speeds and other features to ensure nothing slows you down.

- This 16x4 DOCSIS 3.0 cable modem provides speeds up to 686 Mbps, sixteen times faster than DOCSIS 2.0. A Full-Band Capture digital tuner ensures a faster, more reliable Internet.
- Cable modem's Ethernet port connects to a computer, HDTV, game station, or wireless router. (This Model MB7420 cable modem does NOT have a built-in wireless router and does not have a telephone adapter or phone jack. The Motorola MG7310, MG7315, MG7540 and MG7550 have a built-in wireless router.)
The Motorola MB7420 is the best cable modem for most homes, capable of supporting speeds available to a majority of home internet plans. The MB7420 is ideal for internet plans that top out at 300 Mbps, which covers a wide swath of our household. In testing the MB7420 at my home, I enjoyed steady connectivity, and that’s with multiple people stuck inside, all trying to hit the internet at once.
The MB7420 isn’t as tall as the Netgear CM500, our previous pick for the best cable modem, though some people may prefer the more compact size of the Arris Surfboard modems.back to menu ↑
- Save monthly rental fees: Model CM500 replaces your cable modem, saving you up to $168/yr in equipment rental fees.
- Speeds by carrier: Spectrum (up to 400Mbps), Xfinity (up to 200Mbps), Cox (up to 150Mbps).
The Netgear CM500 remains one of the best cable modems available, because it’s easy to find at most retailers; you can also find it for a little less than the Motorola MB7420 most of the time, making it a good value. (Modem prices can fluctuate so keep an eye peeled for the best tech deals when shopping for a cable modem.) Anytime you can find a new CM500 for $50 or less, that’s a good buy.
The Netgear CM500 works with the biggest cable providers and supports speeds of up to 300 Mbps, which should be enough for the vast majority of Internet users out there. (If you’ve got a high-speed plan, look for a faster modem.)back to menu ↑
- Compatible with Comcast Xfinity, Time Warner Cable, Charter, Cox, Cablevision, and more. Requires Cable Internet Service
- Not compatible with: Verizon, AT&T, or CenturyLink
While most homes opt for internet plans that promise speeds of around 100 to 300 Mbps, some people prefer higher-speed service. If your plan promises download speeds that top 300 Mbps, you’ll want a cable modem that can take advantage of that greater performance. Netgear’s CM600 is the best cable modem for those higher speeds, though you’ll pay a little bit more than you would for the CM500.
Netgear’s modem doesn’t use the same Intel Puma 6 chipset that’s been blamed for latency issues with some other high-speed modems, such as the Arris Surfboard SB6190.back to menu ↑
4.ARRIS Surfboard SB6183-RB
- APPROVED with Comcast Xfinity, Spectrum (Charter, Time Warner, Brighthouse), Cox and more. If not sure call your cable provider to find out if approved to use. REQUIRES Cable Internet Service. Not compatible with: Verizon, AT&T, or CenturyLink
- Cable Modem only (no WiFi router). NO support for Cable TELCO options
The Arris Surfboard SB6183 was once our pick for the best cable modem thanks to its solid performance that will satisfy most home internet customers who don’t pay for high-speed service, though this older modem is harder to find these days. (As of this writing, Best Buy is selling the SB6183.) If you can track down the SB6183 at a competitive price, its two-year warranty also is a big plus.
At 5.2 x 5 x 2.1 inches, the all-white SB6183 can be tucked unobtrusively next to a router, cable box and whatever other hardware you have on hand. The coaxial-cable connector is a little too close to the power connector for my taste, but you’re likely to have to deal with that only when setting up the modem.back to menu ↑
5.NETGEAR Nighthawk AC1900
- Compatible with Xfinity Cable & Voice Plans up to 800Mbps speed.
- Three-in-one DOCSIS 3.0 Cable Modem + AC1900 WiFi Router+ Xfinity Voice and 2 USB ports
While it is certainly pricey, you get incredible speed in an easy-to-use package. Since it’s capable of up to 960 Mbps, this modem is also an investment in the future. While you likely don’t require such bandwidth now, this amount of Mbps means the Nighthawk has speed to spare and will save you from having to invest in a new modem as tech progresses.
While this Nighthawk arguably has the disadvantage of being a dual modem-router, it makes up for it with the unique feature of two included phone lines that function on the Comcast service. Unfortunately, this also means that this device is compatible only with Xfinity and not other phone services.back to menu ↑
- Top Internet Speeds for all Multi-gigabit Speed Tiers - Wirecutter recommends this model as the best cable modem for people using Gigabit Internet plans. Built-in DOCSIS 3.1 and DOCSIS 3.0 32x8 capabilities give top Internet speeds for all cable Internet services.
- Save Money - Eliminate up to 168 dollars per year in cable modem rental fees (Savings are shown for Comcast Xfinity and vary by cable service provider.) Approved by Comcast Xfinity and Xfinity X1, Cox, and CableOne for all speeds including Comcast Gigabit services and Cox Gigablast. Not compatible with RCN. No cable modem is compatible with fiber optic, DSL, or satellite services, available from Verizon, AT&T, CenturyLink, Frontier, and others.)
When buying a modem, it’s imperative that you make sure it will work with either your current router or the router you plan to purchase. The Motorola MB8600 relieves you of that stress—it’s capable of connecting to any Wi-Fi router and, on top of that, has a two-year warranty.
The design is functional, if not particularly attractive, and it has good ventilation to prevent it from overheating. There’s also built-in protection against service attacks and power surges. Reviewers noted that the MB8600 was easy to set up and connect, and confirmed that it worked well with multiple ISPs.back to menu ↑
7.ARRIS SURFboard SBG10
- 3 products in 1: DOCSIS 3 0 Cable Modem, AC1600 dual-band Wi-Fi Router, 2 Port Gigabit Ethernet Router (cable digital voice service not supported)
- Wi-Fi 5 AC1600 dual-band concurrent Wi-Fi Router with 2 Gigabit Ethernet ports
One satisfied reviewer who bought this modem instead of renting one from his service provider says, “let me tell you this is a great product. I waited a few months to write this review and ensure that my Wi-Fi has functioned properly before writing this and so far it has been great and almost paid for itself.”
Another reviewer praises the Arris for its stability in a crowded building: “The apartment complex where I live requires you to have your own modem/router.back to menu ↑
Best Modem for 300mbps – Modems function as your connection to the internet, harnessing it and bringing it into your house, and routers are the means by which you are able to connect your devices to the internet.
However, the notion that you need two separate devices isn’t entirely true. Many companies are now making router and modem combos that both connect to and disperse the internet.
