CenturyLink and Cox are reputable internet service providers (ISPs) that offer different connections and speeds with their internet plans. If you’re looking for multi-service packages, both ISPs have options, though Cox retains the upper hand by offering TV, mobile, and smart home services. In addition, Cox has more cable internet plans than CenturyLink’s offerings. However, you may want to consider CenturyLink for its gigabit internet plan if you have extensive internet needs.

Cox Offers the Best Bundles

Cox Outshines CenturyLink When It Comes to Fees
Cox Offers Free Installation
Cox’s professional installation fee comes out to $100, but you can opt-out when you self-install. CenturyLink’s professional installation costs $85, though its Fiber Gigabit plans waive this one-time charge. While CenturyLink also has a self-install option for its other internet plans, it is not exactly free, depending on where you live.
Cox Has More Generous Data Caps
Cox’s internet plans have a data cap of 1.25 TB, which is more than what the average household needs. You can also upgrade to the Unlimited Additional Data Plan at an additional cost. CenturyLink’s data cap of 1 TB is also pretty generous, though slightly less so.
