Check Availability
October 12, 2021

In the world of internet service providers (ISPs), you often get what you pay for. This means if you want the fastest speeds around, the cheapest isn't always best. Look for speed and reliability metrics alongside price to make sure you get the best internet for your buck.

ISPs have improved over the years and are able to offer much faster speeds to their customers than before. DSL internet was once considered only an upgrade from dial-up, but today many DSL providers are capable of offering fast speeds and plenty of bandwidth.

We’ll be comparing Comcast Xfinity vs. Centurylink DSL to find out which one is right for your home or office based on the following metrics:

Xfinity vs. CenturyLink DSL – which is the best option overall?

Xfinity is the winner in our overall comparison. They offer better speeds, dependability and customer service for today’s connected families.

The 2019 Residential ISP Customer Satisfaction Survey by J.D. Power awarded Xfinity three power circles in three regions: the South, East and North-Central areas, and four power circles in the West. CenturyLink only earned two stars across the board in the same survey.

Although CenturyLink is a reliable service, the coverage area is not as widespread as Xfinity. And while their online reviews are about the same as Xfinity for service reliability, Comcast received more awards due to a recent customer satisfaction survey.

While CenturyLink does have budget-friendly packages, you will pay the same amount for CenturyLink’s download speeds of 100 Mbps as you would for Xfinity’s download speeds of 200 Mbps.
