CenturyLink Compatible Modems Buying Guide

With new technological advancements, CenturyLink internet connections have become more reliable and faster. CenturyLink DSL internet service has vastly improved over the years, and when choosing a modem, you might want to consider several factors.


Your modem options will depend heavily on your CenturyLink plan pricing. You have to look at your plan pricing and check the download speeds promised, and whether the modem can match up. In the future, you might consider options to upgrade your plan, so it only makes sense to invest in a good modem with excellent download speeds.

DSL Capabilities

Along with the CenturyLink plan and internet speed, you need to consider the plan’s technology. For example, when you choose the best CenturyLink Compatible modem, you will be given the options of ADSL, ADSL2, VSSL2, or GPON. These are technologies in telecommunications that determine the mode of data transmission and receipt to and from the device.

ADSL is better than DSL because its data transfer rates are higher. ADSL2 is twice as fast as ADSL, but if you choose a modem with the wrong technology for your CenturyLink Wi-Fi fiber internet plan, you will be unable to optimize the extra speeds.

Wireless Capabilities

All the above CenturyLink compatible modems are examples are all combos, which means they all have in-built routers. If you are looking for excellent wireless speeds, you need to buy a dual-band of 2.4 GHz ,5.4 GHz, or higher modem. The Wi-Fi 6 wireless modem router offers almost the same speeds as when you are connected using an ethernet cable.

Wired Ports

As mentioned before, wired internet connections are faster. If you intend to wire several devices, make sure the modem is capable of supporting them all. Most modems come with one or two ports, and a few good ones come with at least four. The speeds of the ports in the CenturyLink modem are also a significant factor. Some of the ethernet ports offer Gigabit speeds and some of the ports cannot go beyond 100 mbps.


Once in a while, you will need access to the CenturyLink compatible modem’s firmware. You can only do this via vectoring upgrade firmware. If your modem does not have this capability, it may be rendered incompatible, so you need to make sure it does.

Remote Capability 

You may need to let various internet traffic sources connect to your Wi-Fi network. This is significantly handy when it comes to HD streaming, Videoconferencing, and other activities that require high-speed internet services and high download speeds. To do this, get a CenturyLink Broadband Remote Access Server (CBRAS)compatible modem such as a Technicolor C1100T.


Always invest in modems that have a firewall and encryption software. The internet is full of malware and viruses that can attack your DSL modem and wreak havoc on your devices and your data.

Price of the Modem Router

Your ultimate goal in buying a CenturyLink modem is to save some money. There is no point in buying an expensive modem that you will hardly use. A major consideration is how long and how often you will use the CenturyLink DSL modem, and chose a price range based on that.


Where can I buy a CenturyLink Compatible Modem?

This way, you are assured of getting a CenturyLink compatible and functioning device that will work with the service for at least $200. You can also buy a modem from Amazon, but for more money.

Most sellers do not stock CenturyLink DSL modems, but if you have installed CenturyLink fiber internet, you will not have to look for a modem, as CenturyLink will provide one to each customer at no extra cost. However, it may be worth noting that instead of using Wi-Fi, using a wired Ethernet connection makes your internet signal stronger.

Is Netgear Modem Compatible with CenturyLink?

Most of the Netgear modems, such as the Nighthawk d7000 work perfectly with CenturyLink’s ASDL Wi-Fi plan. Some of the more modern Netgear DSL modems may be compatible with VDSL, but if you opt for this, you will not be eligible for Netgear’s tech support.

Why is a Zip Code Necessary?

There are different types of CenturyLink DSL technologies, with each offering faster speeds than the previous ones. Not all areas in the US support the latest DSL technology. Ask a CenturyLink representative which DSL your CenturyLink plan is on, or go to the CenturyLink official website and have a look at their menu list. You will need to provide a valid service address, street address, zip code, and email address for them to check which DSL serves your area.


Instead of renting a modem from CenturyLink, you will be better off buying one via the company instead of buying online.

You have a guarantee that your CenturyLink-bought modem will be completely compatible, functional, and you will save some money in the long run.
