Best Modem for Comcast Xfinity

Best Modem for Comcast Xfinity – While looking for a modem and a router, most people always ask, “Do you have to use the internet connection equipment for your home that the Internet Service Provider (ISP) gives you? The simple answer is No! you can get the best modem router combo for Comcast Xfinity and other ISPs as per these reviews.

Since Comcast has the largest share in both cable TV and broadband cable internet in the US, it is good to consider them for your internet connection. However, you may decide to pick your own router and modem or a combo instead of depending on the ISP-provided one if it is not reliable or offer you an excellent internet connection.


1.Motorola MB8611

The Motorola MB8611 is the perfect option for you with the Extreme Pro plan or below that wants to future-proof your modem.

The MB8611 is such a good modem because it’s both DOCSIS 3.1 and has a 2.5G ethernet port.

This makes it future-proof because when Xfinity upgrades its internet to DOCSIS 3.1, you won’t have to go get a new modem. And since DOCIS 3.1 is backward compatible, it will work with DOCSIS 3.0.


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.

3.NETGEAR Nighthawk Multi-Gig

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.

A speed that Comcast doesn’t even offer yet. Enough to download nearly anything in mere minutes.


The Motorola  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.


The modem is “just enough modem” that will serve you well for now but is not future-proof.

The reason for this is because it’s DOCSIS 3.1 with only 8×4 channels. Which is the lowest requirement for a modem on Xfinity.

But if you’re on a budget and don’t plan to upgrade your internet plan anytime soon, it’s a great option.


Setting up the Orbi CBK40 is so easy that you will be impressed! You can either use the Netgear Orbi app or the web user interface.

First, plug in your Wi-Fi router and wait for it to power on. Then position both satellite units next to each other with rings at their base glowing brightly (the color corresponds). Therefore, press down sync buttons located on the backside of each device by using a ring-shaped LED light top as guidance while aligning them correctly into place.

You can know the status of the sync between the gateway and the satellites using the indicator light. Below is the interpretation:
