CenturyLink Vs Cox
CenturyLink and Cox Communications are both established ISPs (internet service providers), but they take very different approaches to delivering internet service.
CenturyLink’s network is built primarily on DSL technology, which gives it reach into rural areas where cable providers don’t go. The trade-off is that DSL speeds tend to be slower than cable. CenturyLink also has a fiber network, but it’s limited to select metro areas.
Cox delivers internet over its cable network, which means faster download speeds for most customers. Cox is a strong pick for households that want TV bundles, gaming-friendly speeds, and responsive customer support.
Choosing between CenturyLink and Cox depends on your location, budget, and what matters most to you. Below, we’ll compare them on accessibility, customer ratings, pricing, perks, and speeds.
CenturyLink Vs. Cox: Accessibility

CenturyLink Vs Cox – Accessibility
CenturyLink has a presence in all fifty US states, with its DSL internet reaching close to fifty million people. DSL makes up the bulk of CenturyLink’s network.
The rest is fiber internet, which is limited to larger metro areas like Phoenix (Arizona), Las Vegas (Nevada), and Seattle (Washington).
Even though CenturyLink’s fiber coverage is restricted, it still gives them an edge over Cox in one respect. CenturyLink at least offers residential fiber, while Cox has historically focused its fiber services on business customers.

Cox, on the other hand, operates in eighteen US states. Their biggest markets are in Arizona, California, Florida, Nevada, and Virginia.

CenturyLink Vs Cox: Perks

CenturyLink Vs Cox – Perks
Several perks apply to all of CenturyLink’s internet-only plans. Their Fiber Gigabit plan, for instance, includes a “Price for Life” guarantee. That means your monthly fee stays the same as when you signed up, as long as you keep the plan active.
CenturyLink also doesn’t require term contracts. You can pause or cancel your service at any time without penalties.
Cox isn’t as flexible when it comes to contracts. You can pay an extra ten dollars for a month-to-month plan, but if you go with a contract, the prices after the term expires can be steep.

Price is one of the biggest factors when choosing an internet provider. Beyond that, the quality of service and actual speeds you get matter just as much.
Both CenturyLink and Cox have expanded their plan options over the years. Keep in mind that prices may vary depending on where you live.

Final Thought
Overall, CenturyLink’s fiber internet is the better deal here because it delivers gigabit speeds at a much more affordable price than Cox’s cable internet.
The catch is that fiber coverage is limited. And CenturyLink’s DSL service is significantly slower than Cox’s cable internet.
If fiber isn’t available at your address, Cox cable is likely the faster option. But if CenturyLink fiber is available where you live, it’s hard to beat on value.
