Best High Speed Modem for Comcast – 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.
1.ARRIS Surfboard S33
The modem provides 32 downstream channels along with 8 upstream channels for DOCSIS 3.0 and 2 OFDM downstream channels along with 2 OFDM upstream channels for DOCSIS 3.1, with maximum download speeds of 10 Gbps and upload speed of 2 Gbps. The two Gigabit Ethernet ports on the modem makes it great for esports gaming.
The customer support of ARRIS seems really bad, though. Even if the warranty period is 2 years, the company rarely accepts an RMA for the products.
The Motorola MB8600 supports up to 1,000 Mbps download speed. But since Xfinity upped its Gigabit plans to 1,200 Mbps, we suggest you use it only for Xfinity’s Extreme Pro and lower-speed plans.
If you’re living in the fast lane, you’ll appreciate how smoothly this modem streams 4K Ultra HD content and handles high-speed online gaming. And it’s durable, too, so you can expect it to keep you up to speed for years to come.
3.ARRIS Surfboard SB6183-RB
While the ARRIS SB6183 runs on DOCSIS 3.0 tech—older than the DOCSIS 3.1 of the two previous devices—it’s still a zippy little modem.
If you have an Xfinity Blast! or Blast! Pro Plus plan, go for this device to get the speeds you need without forking out a ton of dough.
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.
5.NETGEAR Nighthawk Cable
If you’re getting a voice plan from Xfinity, the NETGEAR CM1150V will help connect your phone service as well as your internet service. Then you can call and tell all your friends about it (lol).
This modem is about as souped-up as the ARRIS S33, so it can handle Xfinity’s Gigabit plan, no sweat.
But this little baby from NETGEAR is a bit pricey, so if you’ve got a slower plan, you can save some money with another product like ARRIS SVG2482AC. This second option can handle speeds up to 600 Mbps, and it comes with a Wi-Fi router built-in too.
It has two integrated phone lines that support a 3-way conference call, which means that you can add a third person to your two-party conversation.
Furthermore, it also supports call forwarding. This allows you to redirect incoming calls to other phone numbers.
The modem also supports DOCSIS 3.1 technology. This, together with its 2.5G ethernet port, makes it’s capable of a staggering 2500 Mbps.
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.
