The 5 Best Modems for Xfinity Reviewed

modem for xfinity

First introduced decades ago, Comcast Xfinity has since become one of the biggest internet service providers (ISPs) for many homes in the United States. Its parent company, Comcast Cable Communications, provides cable and internet services to hundreds of millions of people.

Deciding to use this service provider allows you to choose the type of data plan and speed that work best for you. Keep in mind that your internet’s speed is dependent on what type of subscription plan you settle on.

When you subscribe to Xfinity, you have the option to rent a modem or router costing about $14/month and have it installed for $20. However, many people have disputed these fees and call it unfair. Fortunately, Comcast waives these fees if you decide to purchase your modem or install one yourself.

You are probably visiting this website because you might have heard that it costs significantly less to own your modem for Xfinity than rent one every month, and are most likely searching for the best modem to purchase for your Internet. Do not worry; we have got you sorted out with this list to help you find the most suitable modem.

Best Modems for Xfinity

1. NETGEAR Nighthawk

NETGEAR Nighthawk

If you are most concerned about internet speed and whether you can still get that service on a purchased router instead of renting, then the NETGEAR Nighthawk is the best choice for you. It has three in-built antennas meaning dual band connectivity and can provide up to 600 to 1,300 Mbps on both 2.4GHz and 5.0 GHz bands.

The first thing you will notice about this modem is that it has a modern design; its black plastic casing gives it a sleek aesthetic. At the front of the router are a couple of neon lights that show its performance. Behind the modem, it has a USB 2.0 port, the power cord port, a port for a coax cable, and four Gigabit Ethernet ports. It is not the broadest range of ports but, it should be okay for lots of people.

One of the best things about the NETGEAR Nighthawk is that it is easy to set up. Before installing this modem, ensure that you have all the necessary information with you, such as your relevant ISP information. This modem comes with a manual on how to install it successfully.

Unfortunately, the NETGEAR Nighthawk does not have the best software; but it gets the job done, so it is not too much of a problem, and you can work with it without having any issues. Once you have installed your modem and logged in, you can manage your connection and change your satisfaction settings. Even the not so tech-savvy person will be able to navigate effortlessly. However, for the more tech-savvy, there are advanced options that provide in-depth information on your Internet connection.

The NETGEAR Nighthawk is an excellent all-in-one modem, especially when you are looking for speed. However, its price, at $209, might set you back a bit. It is a one-time cost instead of the $14/month or $168/year cost of renting a modem.

2. Motorola MB8600

Motorola MB8600

Design-wise, the Motorola MB8600 has a sophisticated look; its high-quality grey plastic finishing helps to keep the modem in one place. Therefore, it is not likely to fall if shaken on a desk.

Furthermore, its sleek black design accents pair well with the grey outer body. Instead of a series of neon lights found on most modems, this one has an LED panel to provide information on its performance. Behind this router, you will find one Ethernet port, a coax cable port, and the power button.

If the total bandwidth is one of your determining factors when purchasing a modem, prepare to be blown away by MB8600. It is simply too fast! And the best thing about this modem is that it works in urban and rural areas, where typically Internet connection might not be operating at its maximum.

The Motorola MB8600 is also compatible with multiple devices such as Macs, Windows computers, HDTVs, as well as some gaming consoles so long as they have ethernet connectivity. Additionally, this device also works well with other routers that have WAN ports. However, ensure that your router can meet the speed of the MB8600.

When it comes to setting up this modem, you will find that it is an easy task. If you already have an old modem from your Xfinity subscription, all you have to do is remove its coax cable and insert it into the MB8600. Once completed, turn on the router and wait a couple of minutes for it to configure with your connection.

The Motorola MB8600 costs around $170 and is a less expensive option compared to the NETGEAR Nighthawk. Should you buy it? Yes, mainly because it is a one-time payment, and you will get value for your money. It is also powerful enough to provide you with a high-speed Internet connection if you live outside major urban cities.

3. Linksys CG7500

Linksys CG7500

The Linksys CG7500 has a simple yet stylish design, and since it is both a router and modem, it has more units or components over other modems. This device comes with an ethernet cable, a power adapter, and an installation guide.

It is perhaps one of the easiest modems to install. That is because Linksys designed this device to be as simplistic and less complicated as possible for all users. Everything has been pre-configured to help you get started; for Xfinity subscribers, all you have to do is connect your coax cable and turn on the device. Relevant information, such as your Wi-Fi name and password, is attached to the back of your modem. It takes about a minute or two for your Linksys CG7500 to be up and running.

This device has a filtering system that uses Intel’s Puma 6 Chipset to clear up your internet signal and attempts to improve your network connection.

The Linksys CG7500 can support speeds up to 300 Mbps, as well as any speed subscriptions that are 300Mbps and below. If you max out your speed, that might reduce your bandwidth. Therefore, this modem is an excellent choice for smaller homes and apartments.

There are two significant reasons why you should consider purchasing the Linksys CG7500: its affordability ($150) and its filtering system, which would be excellent for boosting speeds for homes with old wiring or those in rural locations.
