As a rule of thumb, fiber offers the best residential Internet, followed by cable and DSL. Fixed wireless is also a common option in the Denver area, and the technology has improved in recent years to make it a real competitor for wired service.
While DSL is usually less preferable than cable, it’s worth pointing out that in Denver specifically, CenturyLink’s DSL service comes without a data cap, while Xfinity caps at a terabyte/month.

Map of Broadband Internet Competition in Denver
Denver is decently wired when it comes to broadband, and most neighborhoods at least have the choice between DSL and cable. In more central areas, fiber options from CenturyLink and a few niche providers round out the picture.
Something that makes Denver unique is their large fixed wireless provider count, creating some livable deals for farther-flung neighborhoods that might not have access to the latest cutting-edge wired options.

Denver Internet Speed Overview
Comcast Xfinity recently stepped up their game in response to CenturyLink’s fiber expansion, and has been offering gigabit cable service throughout much of their local network in Denver. That said, gigabit cable comes at a high price compared to true fiber, and the upload speed is usually much lower than the “gigabit” download speed advertised.
|Average Speed||90th Percentile Speed|
|41.84 Mbps||105.09 Mbps|

Top Factors to Consider When Shopping for Internet Service in Denver
There are a couple important things to understand before choosing an Internet provider in Denver: how cable and DSL work, and how bundling affects your overall price.
Technology: Cable vs DSL in Denver
As explained above, the main options for home Internet in Denver are cable from Xfinity and DSL from CenturyLink. While CenturyLink offers fiber in some areas, it’s not yet a reality for the vast majority of Denver residents.
…But what’s the difference between cable and DSL Internet? The short version is: cable Internet comes from cable TV companies and is delivered over cable lines. DSL Internet comes from phone companies, and is delivered over phone lines.
Cable generally clocks in with faster speeds and more reliability, but loses points for slowing down during peak use times (usually 5–9pm). The cables are usually buried for at least part of their journey, making cable Internet less vulnerable to weather interruption.
DSL is more budget-friendly, but tends to be a bit slower and less reliable since it relies on above-ground copper telephone lines for delivery. However, it can actually outperform cable in some parts of Denver depending on the distance between your specific address and the local CenturyLink office.
It also creates a direct connection for your Internet rather than the “shared” connection common with cable, so it doesn’t slow down when your neighbors start streaming Netflix at the same time.
Denver-Area Double Play and Triple Play bundle deals
Another reason the difference between cable and DSL matters is because of bundling.
Most wired Internet providers in Denver offer TV and phone service in addition to Internet connections. Bundle those services together, and you’ll probably save some cash every month compared to purchasing services separately.
We found Xfinity to have some of the better TV channel packages, although CenturyLink partners with DirecTV to offer good value if you have space for a satellite dish.
Fixed Wireless Options
The arrival of wireless gigabit service from WebPass, which was recently acquired by Google, has brought new attention to the possibility of a wireless revolution in Denver. As you can see in our list of Denver Internet providers above, wireless is a popular and prevalent option, even in areas where wired options like DSL are available. New advances in fixed wireless technology have given hope to neighborhoods that otherwise would be difficult to reach with wired service.
Denver City Government Broadband Initiatives
While Colorado state holds a few municipal broadband network success stories, Denver itself is currently completely privatized so far as Internet infrastructure. While the Denver area historically supports publicly-funded fiber infrastructure, in practice the community has mostly relied on promoting competition between private companies like Comcast and CenturyLink. The plethora of wireless options in Denver makes it possible for customers to choose another provider if they can’t afford price hikes, resulting in decent price-to-speed value compared to other parts of the state.
Broadband Roadblocks in Denver
The biggest issue currently facing Internet access in Denver is the lack of true fiber infrastructure in the last mile. Installing fiber is expensive, so it’s difficult for private companies to justify the expense unless forced to by competition from other providers.
Denver has been considered by Fiber providers like Google Fiber in the past, but the lack of access to dark fiber and patchwork nature of local infrastructure and regulation has stopped it from making the shortlist for citywide Fiber to the Home (FTTH) service from outside providers thus far.
For more information on the future of Internet access in Denver, we’ve reached out to local government staff and tech organizations for commentary. If you are involved in a broadband initiative in Denver that isn’t featured on this page, please let us know so we can include your information.
