CenturyLink's Technology

DSL and fiber-to-the-home are currently the two most common Internet options CenturyLink provides.

DSL is an older infrasructure that uses Centurylink’s legacy phone lines to deliver broadband Internet. Although DSL services don’t offer the fastest speeds or lowest latencies, they are widely available and usually more cost-effective compared to alternatives since they can transmit data over the same cheap, abundant cables carrying calls.

If you are evaluating DSL services, make sure to check the speeds available in your area, as they can change dramatically.

Fiber-to-the-home (FTTH), on the contrary, is considered the best internet service. In a FTTH setup, CenturyLink delivers a fiber line the full distance to subscriber residences. However, installing fiber lines is costly — such that fiber isn't expanding very quickly.

Suddenlink's Technology

Internet service from Suddenlink come over their hybrid fiber-cable network. Bandwidth is is split to allow TV and digital phone services. Cable is speedier than DSL. However, the upload speeds can't match fiber.

Hybrid networks work by bringing fiber lines to individual neighborhoods, then switching to coaxial copper television lines for the last mile.[2]

The DOCSIS 3.1 protocol for servicing broadband Internet data over coax cable is making high-speed Internet accessible to more areas in the future without expensive updates of existing Suddenlink networks in use.

CenturyLink Installation

CenturyLink subscribers have two installation choices:

  1. Self installation
  2. Professional Installation

Installing services at home is generally straightforward, especially for Internet-only service. All equipment, plus step-by-step instructions, is included with the installation kit. The task should takes no more than half an hour.

Professional installation is necessary if your house has never been connected to CenturyLink DSL before. Appointments can be made when you order service.

CenturyLink customers with pre-wired homes who are okay with following instructions can save money by doing the equipment on their own.

Suddenlink Installation

Suddenlink gives new customers detailed self-install materials for those who want to install their service. The process involves hooking up the modem to the home's coax outlet, activating the router, and some other small tasks.

Although installing yourself should take less than an hour for most residential customers, technician installations can be scheduled as well. Technician setup is the better choice for television customers in particular.

Early termination fees and other surprises

Check the fine print before jumping aboard

Broadband communication companies provide complex services, and those complex services come with equally complex fees. The big ones to be aware of are ETFs (early termination fees) and limited-time pricing. ETFs matter particularly for consumers who anticipate relocating regularly, including renters, students, and etc.

The best-priced plans often include ETFs and multi-year agreements so the provider knows they can make a profit even if the margin on your particular connection is not hugely profitable for them. Additionally, shoppers should be sure to compare and account for the “final price” of plans, not just the limited-time sign-up offer. Sign-up offers can save you money, but ultimately the final price matters more if you’ll be staying with the same provider for years.

Pay up-front to avoid rental fees

Modem rentals aren’t something you have to have

Modem rentals are a common offering for Internet providers, providing them with a stable source of low-cost revenue while streamlining the installation and upkeep process for customers. It’s a win-win for people who don’t want to mess with the home network or move too much for owning hardware to be practical, but it’s a losing proposition for everyone else.[1]

First, check with your provider about which makes and models of modem/router are compatible with their network. Second, pick a model that can handle the bandwidth you’re paying for. The savings on rental costs should pay for it within the year, and after that it’s a simple way to save $100 or so per year.
