Best Modem for Xfinity – While considering buying a modem, it’s important to take note of the average internet speeds available with your internet service provider because it is only worth investing in a high-speed and a costly modem if the internet speed provided by your provider is also high speed. It is smart to buy a modem that supports the maximum internet speed provided by your internet service provider.
No one would want to replace and reinvest in a new modem again soon after buying a new modem. So, do not select extremely slow and low range or extremely cheap modems or the 8×4 modems as the internet service providers are dropping support for these 8×4 modems.
ROUND UP
1.MOTOROLA 16×4
Features
- 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.)
- Requires cable Internet service. Certified by Comcast XFINITY for residential speeds up to Extreme 300, by Comcast Business for speeds up to Deluxe 250, Time Warner Cable, Cox, Charter Spectrum, BrightHouse, and other leading cable service providers for modem ownership programs that typically save rental charges of 120 dollar or more per year
- Setup is fast and easy with a few quick steps set out in a Quick Start guide. Experienced USA-based customer support specialists are there to help if you need them.
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.
2.NETGEAR CM500
Features
- 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).
- Works with any wifi router: Connect any WiFi router to this modem's Ethernet port to support all your wireless devices.
- Ethernet connections: 1 Gigabit Ethernet port connects to your computer or separate WiFi router.
- Modem technology: Engineered with 16x4 channel bonding and DOCSIS 3.0.
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.)
3.NETGEAR CM600
Features
- Compatible with Comcast Xfinity, Time Warner Cable, Charter, Cox, Cablevision, and more. Requires Cable Internet Service
- Not compatible with: Verizon, AT&T, or CenturyLink
- Cable Modem only (no WiFi router).Memory: 8 MB NOR flash and 128 MB RAM
- Support Cable Internet Service plans up to 300Mbps. Recommended for all speed tiers up to 500 Mbps. Separate router required for WiFi. 24x8 channel bonding
- DOCSIS 3.0 Cable Modem with 1 Gigabit Ethernet port. DOCSIS 3.0 unleashes 8x faster download speeds than DOCSIS 2.0
- Ideal for streaming 4K UHD content, fastest downloads, and high-speed online gaming
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.
4.ARRIS Surfboard SB6183-RB
Features
- 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

- 90 Day Warranty. ARRIS Certified Refurbished. US Technical support. ARRIS Certified Refurbished products will ALWAYS be branded ARRIS, Never Motorola! If you get Motorola branded product they are illegitimate, need to be returned to Seller and Reported to Amazon
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.
5.NETGEAR CM700
Features
- Compatible with all major cable internet providers: Including certification by Xfinity by Comcast, COX, and Spectrum. Not compatible with Verizon, AT&T, CenturyLink, DSL providers, DirecTV, DISH and any bundled voice service.
- Save monthly rental fees: Model CM700 replaces your cable modem saving you up to 168 Dollars/year in equipment rental fees.
- Speeds by carrier: Xfinity (up to 800Mbps), Cox (up to 500Mbps), Spectrum (up to 400Mbps).

- Ethernet connections: 1 Gigabit Ethernet port connects to your computer or separate Wi-Fi router.
- Modem technology: Engineered with 32x8 channel bonding, OFDM 2x2, and DOCSIS 3.1.
Xfinity’s xFi Gateway acts as both a modem and a router, so if you swap to your own equipment, you’ll need both. You can buy a modem and a router separately, or you can go for a combo like the NETGEAR Nighthawk C7000.
And, let’s face it. You could spend almost the same amount for just a modem. So the C7000 might save you more money in the long run.
6.NETGEAR CM400

This affordable Xfinity-compatible modem is reliable and easy to install. For a bargain modem you can set and forget, it doesn’t get better than this.
Although this modem doesn’t have the latest DOCSIS 3.1 technology, it uses DOCSIS 3.0 technology at speeds most Xfinity households will appreciate. And if that techy talk has you baffled, don’t worry. We’re just saying the NETGEAR CM400 will take good care of you and your Xfinity plan.
Your favorite writer (me) uses the NETGEAR CM400 at home when I’m not testing out the Xfinity xFi Gateway. It’ll be a perfect fit for you, too, if you use Xfinity’s Performance Starter or Performance Select plans.
