Comcast Business internet, servicing small to midsize startups for over a decade, is a solid alternative to the DSL internet connection that’s currently forcing your employees to squeeze 20 pounds of data through a 5-pound tube. It may cost a little more than similarly micro-focused providers, but its dependable, fast network—not to mention a coaxial cable infrastructure that spans most of the US—rates a look for your expanding shop.

Comcast Business internet provides businesses reliability and speed

Comcast is everywhere, like Starbucks and Pizza Hut, Comcast is everywhere—they don’t necessarily make everyone’s favorite latte or pepperoni slice, but they’re probably serving it somewhere near you.

Comcast Business’s far-reaching availability and reliably stable high-speed internet service are, however, counterbalanced by an 800-pound gorilla with a headset: a notoriously iffy customer service reputation. Still, with five service packages geared toward small businesses and, again, sheer ubiquity, Comcast Business internet is a definite startup contender—just be prepared to pay a little more for it.

In some parts of the country, Comcast Business utilizes fiber-optic connections, which transmit light through glass or plastic threads instead of electromagnetic cables. The biggest advantages of fiber are less signal loss and interference and evenly matched upload and download speeds (more on Comcast Business fiber availability later).

Comcast Business internet plans

  • Starter Internet is a bare-bones setup for a two-employee operation. Its modest 25 Mbps can handle basic web browsing and email functions but little else. It’s not recommended for heavy file traffic.
  • Business Internet 100 is for a 10-employees-and-up shop conducting serious online business. Its 100 Mbps speed can easily shoulder website hosting and cloud-based applications with room to grow.
  • Business Internet 300 is a beefy choice for medium-to-large offices, with enough speed and bandwidth to handle all of the above, as well as video and audio streaming. recommends this Comcast Business plan as a price-to-power value.

What you should know about Comcast Business internet

You’ve heard it: Comcast has terrible customer service. It’s legend, but not entirely accurate—most of those complaints are aimed at the residential Xfinity side of the service. Comcast Business fares better in customer satisfaction. Most online customer reviews give positive feedback on the company’s internet speeds and support, while many negative comments regard pricing.

Comcast Business internet sells itself as being “built for business,” specifically small business, promising quick resolutions to service interruption.

Comcast Business internet sells itself as being “built for business,”1 specifically small business, promising quick resolutions to service interruptions—including billing credits for downtime and the previously mentioned money-back guarantee trial period. Industry reviews from J.D. Power and here at rank Comcast’s overall small-business internet service just below that of Verizon Fios (which is less widely available) and AT&T (which is more expensive).2


Even though—or perhaps because—it falls somewhere between its competitors on several fronts, there’s plenty to like about Comcast Business internet. Mbps to Gbps, speed is speed, no matter which company is providing it.

Comcast Business internet FAQs

What’s the difference between Comcast and Xfinity?

Xfinity is the consumer, or residential, division of Comcast, providing household TV, internet, and phone services. Comcast split in 2010 to differentiate home services from business customers, as well as to “refresh” its cable-provider image from decades past.3

The move to Xfinity TV and internet was also called out as a play to distance Comcast from its notoriously terrible customer service reputation and has generally just confused the public to this day. Also, besides being Xfinity’s parent company, Comcast also owns NBCUniversal and its stable of more than a dozen broadcast and cable TV networks plus TV and film production studios.

How much speed does my business need?

The real answer is “all of it”—who wants anything less than the fastest internet connection? The question should be, How much do you want to pay?

Comcast’s Starter Internet at $69.95 a month would satisfy the basic online needs of a pair of employees with just 35 Mbps. The Business Internet 100 package ups the speed and user capacity for an additional $40 a month, all the way up to Business Internet 300, which can handle up to and beyond 10 employees—and large file transfers and heavy hosting traffic—for $164.90.

The takeaway

Comcast Business internet is an attractive option for a small business that requires speed and stability and is willing to pay a little more for it.

It’s neither the fastest nor the cheapest, but Comcast Business internet is reliable, available, and loaded with extra features to sweeten the deal. Apart from the monthly pricing, it’s a small-business-friendly service that offers room to grow (to a point). And while there are some of the usual service and outage complaints, Comcast’s past negative customer service reputation doesn’t necessarily apply to its business internet division.

Comcast Business’s client base is showing rapid growth, and the company is building its infrastructure to keep pace.4 It’s only growing, so we’re certain Comcast could be the answer for your small business's internet connectivity needs.
