How we chose the best modem/router for Spectrum

When searching for the best Spectrum modems and routers, our goal was to find those with excellent value. We compared eight devices by using the criteria of supported speeds, price, features, customer reviews and what plan it’s best for.

Each of the devices we chose is a modem/router combo that is best-suited for a particular one of Spectrum’s internet plans. The modem/routers we chose come at varying price points, so there’s one for every budget.

Best modem/router combo for Spectrum internet: Netgear C6220

The Netgear C6220 is a great choice for an internet modem/router on a budget. The device supports internet plans with up to 200 Mbps, making it a great choice for the base Spectrum internet plan. Keep in mind that because of the relatively low speed, this device wouldn’t be suitable for any other Spectrum plans.

This device is clearly a popular choice with customers. It has more than 18,000 reviews on Amazon, with an average rating of 4.4 out of 5 stars. Customers especially like that the device is easy to use and easy to install. The product comes with a one-year warranty and 90 days of technical support.

As far as technical specifications, the Netgear C6220 comes with DOCSIS of 3.0, which meets the industry standard. It also has 802.11ac Wi-Fi and 8×4 channel bonding. Finally, it includes two gigabit Ethernet ports and one USB port.

What to look for in a Spectrum compatible modem and router

When you rent your equipment from Spectrum, you’re guaranteed to get an internet modem and router that’s compatible with the company’s internet plans. But when you purchase your own equipment, you have to do a bit more research to ensure the modem and router you choose has the best features and is compatible with Spectrum internet plans. Here are a few things to look for when choosing your internet modem and router:

Speed compatibility: Each internet device is designed to be compatible with certain internet speeds. For example, the Netgear C6200 on our list specifically states that it’s best for internet plans up to 200 Mbps. Ultimately, it’s important to make sure the modem/router you choose enables you to use the maximum internet speed available with your Spectrum internet plan.
Channel bonding: Channel bonding is a way to maximize your internet speed by combining two adjacent internet channels. The more channel bonding your device has, the more traffic it can handle without interruption or slowdown. The Arris Surfboard and Netgear Nighthawk on our list each have 32×8 channel bonding, meaning there are 32 dedicated downloading channels and eight dedicated uploading channels.
DOCSIS technology: DOCSIS stands for “Data Over Cable Service Interface Specification.” DOCSIS is the industry standard for cable modems that allows for high-bandwidth data transfer over existing coaxial cable systems. The modem/routers on our list have either DOCSIS 3.0 or 3.1
Security: It’s critical that you make sure your internet connection is fully secure. The best way to do that is to find a device with a password with at least WPA2 or WPA3 encryption.

Need a faster internet plan?

One of the best ways to improve your internet speed is to shop around for a faster internet plan. In some cases, that might mean upgrading to a better plan with your existing internet service provider. On the other hand, you might decide to choose a different internet service provider (ISP) altogether. You can use Allconnect’s search tool to find the best internet plans in your area.

The bottom line

Having the right modem and router can make a significant difference in improving your internet speeds. While many people choose to rent devices from their ISPs, there are actually many benefits to buying. Not only is there a long-term financial benefit, but you also have the ability to shop around and find the best device for your needs.
