Best Modem for Xfinity Gigabit – When shopping for a new modem for gigabit internet, you first need to determine its compatibility with your current internet connection. Check the tech specs or call your provider to make sure the modem works with your internet plan.
Second, make sure that it has a good warranty. You should be able to register the modem with the manufacturer and call customer support if there’s ever a glitch in the hardware.
Finally, get a modem with multiple Ethernet ports. You can link Ethernet ports together to create one super-fast wired connection or use them separately if your internet plan supports multiple IP addresses.
The Motorola MB7621 is an Xfinity-certified cable modem that comes with wired speeds of up to 1,000 Mbps.1 That covers pretty much every single Xfinity internet plan (aside from its extremely limited 2,000 Mbps plan).
At about 8 inches tall and 2 inches wide, the MB7621 is fairly inconspicuous. That’s perfect if you’re trying to keep electronic equipment from being the star of your home office.
If you don’t get Xfinity’s Gigabit plan, you can save a little money with the budget-priced NETGEAR CM500 modem. It supports wired internet speeds up to 680 Mbps.2
User reviews of the CM500 note that its installation was a breeze. So if you’re putting off getting your own modem because you’re not tech-savvy, give the CM500 a go.
Our only complaint about this modem (and all NETGEAR modems) is that it comes with only a one-year, limited hardware warranty.
The SURFboard SB8200 uses newer DOCSIS 3.1 technology to support download speeds up to 2,000 Mbps (or 2 Gbps).3 That’s perfect if you’re rocking Xfinity’s Gigabit internet plan—or if you’re running your home business on its 2,000 Mbps Gigabit Pro plan.
We’ve recommended ARRIS’s SURFboard routers before, so it’s no surprise to us that the SB8200 made it into our top-five lineup.
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.
The router also comes with excellent features like beamforming, which directs your Wi-Fi signal to your devices. (Think of it like lining up for a slam dunk versus blindly throwing 20 balls in every direction and hoping for a basket.)
Not surprisingly, that’s hard to find these days. But the NETGEAR Nighthawk CM1150V packs in all the features into one six-inch-high black box. You’ll get DOCSIS 3.1 technology that supports wired download speeds up to 1,000 Mbps, and you’ll get two phone jacks that are compatible with Xfinity Voice service.
Granted, all those features cost a pretty penny. So if cost-savings is what you’re after, you might try the cheaper ARRIS SBV3202—just be aware it supports speeds only up to 600 Mbps.
Just as the awe-inspiring name suggests, the Nighthawk C7800 is a formidable beast built for serious gamers and ’net users. This gigabit modem router combo comes out of NETGEAR’s famed Nighthawk hardware series, acclaimed for delivering not just fast gaming speeds but also firewall protection against hackers.
The C78800 delivers dual-band Wi-Fi and works for both DOCSIS 3.1 and DOCSIS 3.0. The four trusty gigabit Ethernet ports will let you set up link aggregation to push past 1,000 Mbps speeds, so long as your cable company has the capacity for higher-speed gigabit plans.
The ARRIS SURFboard SBG8300 is a DOCSIS 3.1 modem with a dual-band Wi-Fi router attached. In that respect, it’s pretty much just like NETGEAR’s Nighthawk C7800, only without the Nighthawk’s red, wavy stripe, cool antennas, or added security features.
The big bonus here is that you can save on space in your home and maybe a little money by opting for a gigabit modem router rather than having to shop for both a modem and a router.
Best Modem for Xfinity Gigabit – 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.
