Comcast Business is one of North America’s leading internet service providers.

One sort of service that many people search for but sometimes miss is modem options.  Comcast provides a variety of internet and telephone services to residential users, but many business owners are unaware that Comcast also offers a business suite of products. This article discusses the best Comcast Business modems for your business. Let’s take a closer look!

Frequently Asked Questions (FAQs)

Just in case you wonder...

What is the difference between a modem and a router?

Both are little boxes with connectors, but only a modem links your house to the worldwide network. A router is what permits other devices to connect to the network through a wireless signal. It also enables such gadgets to communicate with one another.

Is it necessary to have both a modem and a router?

Users’ requirements differ, thus some set up a modem to which gadgets will be directly linked. Others have equipment that cannot be plugged in, so they acquire a router to transmit the signal wirelessly. However, a modem is not required since routers can be used to form a LAN without Internet connectivity on their own.

Is it necessary for my ISP to approve my cable modem/router?

Yes, in most circumstances. Since your cable modem must be registered with your ISP in order to function correctly, it’s essential to get one that is guaranteed to be compatible. While some ISPs will allow you to register any cable modem, the majority will refuse to set up one that isn’t on their authorized list. Fortunately, most major cable providers in the United States have already “pre-approved” all of the main manufacturers’ cable modems. This information is usually included on the package or the manufacturer’s website, but if you’re still unsure, you can always ask your cable provider whether the modem/router you’re contemplating will operate with their network.

Do modems have an impact on your internet speed?

If your modem fails or is slower than the specified maximum speed for your plan, it might affect your internet connection. You can’t also instantly improve the speed of your connection by getting a modem that is faster than what your plan permits.

Promising review:

I had much difficulty with the installation, but as it turns out, I had it right all along. My problem was that I did not wait for my router (Airport Express) to sync with the modem after installing. I'm so glad that I will not be paying Comcast anymore for modem rental. I should have purchased my own modem years ago!

Has bee in service several years with no issues. Does a great job with my Comcast cable internet service. Does run a little hot (as do all cable modems) so I placed a small 12VDC fan next to it to blow air into it to extend its life.

Promising review:

Needed a Comcast approved modem that would work at 100 mb/s and higher. Was able to switch out the other modem which I also owned and get this working without a phone call to Comcast. Just know that the second ethernet port is not active, as Comcast only provides one IP unless you purchase a second IP before using.
