The Best Modem For Xfinity in 2024: Recommended by Experts

The best modem for Xfinity for use with any connection speed is the ARRIS S33. However, if you have a slower plan, such as Performance Select or Performance Starter, your internet will still function properly with a budget-friendly modem, such as the NETGEAR CM400.

Although renting the upscale Xfinity xFi Gateway has its advantages, purchasing an Xfinity-compatible modem is ultimately the least expensive. Let's save you some money by using the best Comcast modems for Xfinity.

1. ARRIS S33: Best Xfinity-compatible Modem for Gigabit

In our opinion, the best modem for Xfinity is the ARRIS S33, in our opinion. Our hearts are fluttering over this stunning beauty from ARRIS. It has the most recent DOCSIS 3.1 technology, which is exactly what you need to truly exploit your Xfinity Gigabit package - even with the increased speed of up to 1,200 Mbps. 

However, it will cost you money if you want to use the most advanced modem technology. To be fair, if you already pay for Xfinity's Gigabit plan, you presumably have enough money in the bank to not be concerned about the $199.99 up-front cost in exchange for the savings you'll experience over time.

However, the rest of us will continue using the inexpensive modems.

2. Motorola MB8600:  Best Xfinity-compatible Modem for Extreme Pro

The Motorola MB8600 has download speeds of up to 1,000 Mbps. However, given that Xfinity increased the speed of their Gigabit plans to 1,200 Mbps, we advise using it exclusively with the Extreme Pro and lower-speed Xfinity plans.

You'll enjoy how easily this modem manages high-speed online gaming and 4K Ultra HD content streaming if you prefer to live in the fast lane. Additionally, it is strong, so you can count on it to stay reliable for many years to come.

The ARRIS SB6183 is a quick small modem even though it uses DOCSIS 3.0 technology, which is less modern than the DOCSIS 3.1 of the two preceding devices. Choose this device if you have a Blast! or an Xfinity Blast! Pro Plus plan to receive the speeds you require without spending a fortune.

4. NETGEAR CM400: Best for Performance Starter and Select

This inexpensive Xfinity-compatible modem is dependable and simple to set up. For a budget modem that you can set and forget, there's no better choice. 

While using DOCSIS 3.0 at speeds most Xfinity households will enjoy, this modem lacks the most recent DOCSIS 3.1 technology. And if all of that technical jargon confuses you, don't fret. We can assure you that  the NETGEAR CM400 will look after you and your Xfinity plan.

If you subscribe to one of Xfinity's Performance Starter or Performance Select plans, it will also be the perfect fit for you.

The NETGEAR CM1150V will assist in connecting your internet and phone services if you choose an Xfinity voice plan. After that, you can phone and inform all of your pals about it.

This modem can easily handle Xfinity's Gigabit plan because it is relatively as powerful as the ARRIS S33.

However, this modem from NETGEAR is somewhat expensive; therefore, if your plan is slower, you can save some money by using something else, such as the ARRIS SVG2482AC. This second choice also includes an integrated Wi-Fi router and can tackle speeds of up to 600 Mbps.
