Internet Providers in Denver, Colorado

Best Internet Providers in Denver, CO

The best internet service company in Denver is Quantum Fiber, which offers broadband internet with speeds of up to 8 Gbps on a fiber connection. That, to be clear, is very fast — more than fast enough for even the largest households and heaviest internet power-users.

Quantum Fiber isn’t available everywhere, though. It’s only available at about half of all Denver street addresses. If you can’t get Quantum in your area of Denver, you’ll have to consider other options.

The next-best option after fiber is cable internet. In Denver, that means Xfinity, which covers 99.0% of Denver. Xfinity offers internet plans that start at $30 and bundles that start at $55, and it offers speeds of up to 1 Gbps on its fastest plans.

There is one other provider in town that uses fiber in its network: Google’s Webpass home internet service. Webpass uses fiber internet for most of its infrastructure, but it connects individual homes to its network using wireless connections. This is similar to how 5G home internet services work. It’s a pretty effective way to leverage fiber’s ability to handle huge traffic. In shared parts of the network in Denver, fiber is there to handle the combined load, without having to build out fiber connections to every house in town. As cool as that is, we still give Quantum Fiber the edge as the best fiber provider and best overall internet provider in Denver.

Fastest Internet Providers in Denver, CO

Of all of the internet service companies in Denver, the fastest broadband provider is Quantum Fiber. Their top plan can reach speeds of up to 1 Gbps.

When considering speed, remember that not all types of broadband are created equal. Fiber-optic connections will give you upload speeds that are just as fast as your download speeds (a feature known as “symmetrical” speeds), whereas cable and DSL providers will offer faster download speeds and slower upload speeds. Fiber networks are also better suited to handling high-traffic hours — without slowing down or throttling your connection.

Internet Availability in Denver, CO

Like most big cities, Denver has one major cable internet provider available all over town (in Denver’s case, it’s Xfinity). But whether fiber is available in Denver isn’t quite as straightforward. Depending on where you live, powering your Wi-Fi up with a fiber connection may or may not be possible. It all depends on if you live in a place served by Quantum Fiber.

Quantum’s availability is its most limited downtown. In the central business district and Civic Center, availability varies from block to block. You may not have Quantum Fiber available up in Five Points or in RiNo, either.

Quantum Fiber does, however, have great coverage in other areas. In most parts of North Denver, you’ll be able to get a Quantum internet plan. Park Hill and Central Park are well-served by Quantum, as are most areas to the east and south of the Denver Zoo. You’ll likely be able to get Quantum Fiber down near Washington Park and the University of Denver, too.

Many areas of Denver also have access to DSL internet from CenturyLink. While it’s not our top recommendation, this service is widely available downtown. You’ll be a little less likely to see it in neighborhoods on the eastern side of Denver, however.
