Spectrum Approved Modems & Modem/Router Combos [The Official List]

How to Setup & Activate Your Spectrum Modem?

1. Steps to set up a modem

Since you’ve got your modem for Spectrum internet, it’s time to install it yourself. Self-installing a modem might save you a couple of dollars and a long wait for the agent to come in and do it for you.

The process isn’t very arduous and requires you to follow a few easy steps, which are as follows:

• Connect one end of the coax cable to the modem and another end to the power outlet, and turn on the switch.
• Wait for the indicator light on your modem to remain stable. It takes around four to six minutes, but the time can lengthen if the device undergoes a firmware update.
• Then connect one end of the Ethernet cable to the modem and the other to the computer or back of the router. That’s it, you have successfully set up your modem.

2. Activating your Modem

Setting up the modem means half of your job is done. Now, all that is left is its activation. Here are a few easy steps for you to follow:

• Open the browser on your computer, launch the official Spectrum website and log in to the admin portal using the credentials imprinted on the rear side of the modem.
• Once logged in, an indicator light on the modem turns on. It isn’t there in many routers, so in that case, try using the internet after some time.

3. How To Hook Up Spectrum Cable Box and Modem?

Before you hook up the cable box and modem, ensure a standard connection is established on both devices. Besides, ensure you have coaxial cable splitters, a network pack, and coaxial cables. As you have these with you, follow a few simple steps to complete the process:

• Start with placing all your devices in an optimal position, i.e., near a power outlet.
• Connect one end of the cable that comes out of the wall socket to one end of the coaxial splitter.
• Plug one end of a coaxial cable into the splitter and the other into the cable box.
• Use the other output of the splitter to connect with the modem or modem-router combo.
• Then, if you have a separate router, use the Ethernet cable to connect with the modem.

For detailed step-by-step information with pictures, check my complete guide on hooking up the Spectrum cable box and modem.

4. Returning the Existing Spectrum Modem

Since you’ve got your Spectrum modem up and running, you need to return the Spectrum-provided modem to avoid any charges. It isn’t a headache as it feels to be, and here are the steps you should follow:

• Place an equipment return request on the Spectrum official website, citing an appropriate reason.
• Once approved, the networking company sends a cardboard box with bubble wrap and a return label.
• After properly packing the equipment, return the box to a dropoff box or a FedEx store.

Things To Consider When Buying

Each of the Spectrum-supported modems caters to a specific user base and internet plan. Yet, if you want to choose better, here are the factors to keep in mind:

Your requirements

Before you proceed further, you must take a closer look at your requirements. For instance, getting a combo makes sense if you want to ditch a separate router. Or, if you have multiple bandwidth-hogging devices at home, purchasing a modem with several ethernet ports makes sense.

Consequently, a combo will be priced higher, whereas a standard DOCSIS 3.0 modem will be way more affordable. Therefore, once you fix the budget and then the requirements, you can zero in on all the appropriate choices in the given bracket.

Make sure that the modem is compatible with your Internet Plan

Plans	Max Download Speed	Max Upload Speed	Price
Internet	Up to 100 Mbps	Up to 10 Mbps	$49.99/mo
Internet Ultra	Up to 400 Mbps	Up to 20 Mbps	$69.99/mo
Internet Gig	Up to 940 Mbps	Up to 35 Mbps	$109.99/mo

It goes without saying that you need to check the compatibility quotient with Spectrum’s internet plans before proceeding with a buy. For instance, if you are a gamer interested in the Internet Gig plan, a DOCSIS 3.1 modem with even a multi-Gig ethernet port makes sense.

However, if you only want to go with the Ultra or standard Internet Plan with 400 Mbps and 200 Mbps, a mid-range modem with DOCSIS 3.0 might also fit in well.

DOCSIS Tech & Channel Bonding

If you have eyes on a future-proof device for accommodating multi-gig internet plans, DOCSIS 3.1 is the way to go if and when they arrive. That way, you can access thicker transmission channels via 2 x 2 OFDM and 32 x 8 channel bonding. This is the ideal DOCSIS version for high-speed connections. DOCSIS 3.0 with at least 24 x 8 channels makes sense for anything mid-range.

Regardless of the DOCSIS version, getting something backward compatibility is advisable.

Ports & Connectivity

Getting a modem with at least two Gig ethernet ports makes sense if you prefer wired connections over wireless. And if you seek wireless support, look for a combo that can offer cumulative wireless throughput of almost 3000 Mbps and coverage of over 2000 Sq Ft.

And just like using your own modem, you can use your own Spectrum-compatible router or mesh WiFi with Spectrum.
