CenturyLink vs. Cox Performance Overview

Supplying broadband services across 50 states in the U.S., CenturyLink offers four different types of internet access: DSL, fiber, copper, and fixed wireless. If fiber is available in your area, you can have access to speeds up to 1000 Mbps. In addition to internet service, CenturyLink customers can opt to bundle with Prism TV and/or phone services.

Cox Internet offers two types of internet access: cable and fiber. While their cable internet can deliver fast internet speeds, fiber takes it to the next level, providing speeds up to 940 Mbps. Like CenturyLink, Cox customers are offered a wide variety of internet plans and bundled options that include high-speed internet with phone and/or TV services.

CenturyLink Installation

Both self-installation and professional installation are offered to CenturyLink customers.

CenturyLink’s professional installation can cost up to $125. Their self-installation option can cost up to $50. Installation fees vary depending on the plan you select and the coverage availability in your location.

Cox Installation

Cox Internet offers professional installation for a fee that starts around $50 or self-installation for a one-time charge of $20.

If you opt to self-install, Cox will send you a self-install kit to guide you through the installation process. However, Cox’s Gigablast fiber-optic plan requires professional installation where a certified technician installs specialized equipment in your home.

CenturyLink
Contracts, Equipment Fees & Fine Print

CenturyLink gives you the ability to choose between a contract plan or you can pay an extra fee for a contract-free option.

CenturyLink customers that sign up for an agreement may face early termination fees if the contract is terminated early. Regarding equipment, CenturyLink offers to lease a modem for $15/month or you can purchase a modem for a one-time fee of $150.

Cox
Contracts, Equipment Fees & Fine Print

Most of Cox Internet’s plans require a 1-2 year agreement.

Their agreements usually last for a year and allow customers to cancel their service at the end of the 12 month period. If you choose to cancel outside of this window, you may face early termination fees up to $240. Similarly to CenturyLink, Cox gives you the option of renting a router for $10.99/month or you can purchase the equipment for a one-time fee of $129.99.

CenturyLink Data Caps

For the majority of its plans, CenturyLink imposes a 1 TB data cap. However, customers on a business, Prism TV, or 1 Gig plan are exempt from these limits. If you exceed your data cap limit more than three times, CenturyLink will start charging a fee of $10 for every additional 50 GB used.

Cox Data Caps

Cox Internet employs a 1 TB data cap for most of their plans.

We switched to CenturyLink and could not be happier. It is so much faster, has never cut out and had the best installation customer service. The price is also great.

Continued Charges For Many Months After Moving!

I cancelled my Century Link service a week before before I moved from my home in mid-June. I went online to copy off the return tags to return their receiver, and sent that back as directed in June also. After 2 more phone calls, I am still getting charged $100.29 MONTHLY for a service I no longer receive. I’m now trying to call a 3rd time to speak to a representative but cannot get a live person. Ideas? BTW, I’ve finally decided to dispute these charges on my MasterCard. I wish I would have thought of this earlier and hope Century Link finally understands that I have moved and sent back their equipment.

Cox Communications

The customer service is about the same as any other company. Very reliable internet service with almost no outages. I get at least the speed I pay for if not more. The main downside is pricing, it can get expensive after promotions expire.

Customer service sucks

No phone to contact a human. When you figure it out they just transfer you all over the place and if you happen to do the texting then it will go nowhere after hours. Give us the run around! And nothing happens
