Modems and routers are used in many homes, offices, and even in public places. Now, the combo modem and routers are available. These combo modems and routers allow you to enjoy the benefit of both devices in a single device. CenturyLink is a telecommunications company within the United States, and it is a popular choice for many individuals that need a digital subscriber line.

Finding the best modem that works with your DSL can be cumbersome. That is why we have compiled a list of our top 8 CenturyLink Modems. All the items on this list are modem routers; they are compatible with ADSL, VDSL, or both and are relatively affordable. The modem routers on this list range from basic to advanced use devices.

If you’ve been out there looking for an Internet provider, you’ve likely come across many. However, there are probably two names that you are hearing or seeing more than most. This would be Xfinity and CenturyLink. Both are titans in the DSL industry, as they provide DSL networking along with a wide range of other security services. Regardless of which provider you decide to go with, you’ll need a DSL modem.

Most DSL modem manufacturers design modems specifically for certain ISPs. For instance, it is likely that you will only find modems that are compatible with CenturyLink or Xfinity. You won’t likely find modems that work with both providers. How do you know which are compatible with which provider? The best answer is to head over to CenturyLink’s website.

While some of the modems on the list are better than the others, they will allow link up and work with CenturyLink Internet services. How do you know which are better? There is no denying that the long list of names makes the selection process all that more difficult, but before you discover how to determine the best, there are some other things that you need to consider.

First off, you don’t even have to buy your own modem. You can just rent one from the company for $10 a month. Of course, this is something that’ll add up over time, and buying that new modem will practically pay for itself. Not only this, but you’ll likely get better performance out of a modem that you purchase out of pocket because CenturyLink will only provide you with the most basic of models. And, they might even be used by previous customers.

As of right now, CenturyLink offers 6 unique subscription plans. This would be the Life 15 plan that offers 15Mbps of speed, the Life 20 that offers 20Mbps of speed, the Life 40 that offers 40Mbps of speed, the Life 80 that offers 80Mbps of speed, the Life 100 that offers 100Mbps of speed, and the Fiber Internet, which guarantees anywhere from 900 to 940Mbps of speed.

These various data plans only make the modem selection process that much more difficult because you’ll want to match your new modem to your plan. For instance, a modem capable of 940Mbps is going to cost more than one capable of 80Mbps. On the other hand, what’s the point of buying a 940Mbps capable modem if you are only going with the Life 100 plan or 40Mbps plan?

We have also listed the pros and cons of each item on this list to help you make an informed decision on which modem to purchase for your CenturyLink DSL.

CenturyLink Compatible Modems Buying Guide

DSL is an Internet service that has improved through the years. Newer technologies available today allow for faster and more reliable connections. When selecting your new modem, you’ll want to take this into account along with a variety of other things. That said, your end choice will heavily weigh on the type of plan that you are going with. Look at your current plan and see what speeds you are promised.

You’ll want a modem that can match what you are paying for. Also, consider if you might upgrade in the future. Will there be a viable need for you to increase speed? If so, you might want to go ahead and make the investment of the more powerful modem. Couple this with the most prominent features of any modem and you’ll have the perfect modem for your specific needs narrowed down. What are the most important features?

DSL Technology Capabilities

Not only will you need to consider the speed of the plan you are choosing, but you’ll also need to consider the technology of that plan. For instance, when choosing your modem, you’ll notice that you’ll have options between ADSL, ADSL2, VDSL2, and GPON. These are basically telecommunication technologies, which determine how data is sent and received to and from the modem.

ADSL is superior to that of DSL because it allows for much higher data transfer rates. ADSL2 is twice as quick as ADSL. However, if you don’t choose a modem that supports the right technology for your plan, you won’t be able to take advantage of the extra transfer speed.

Wireless Technology Capabilities

You’re in luck because every modem on this list is a combo, which means it has a built-in router. However, if you want good wireless speeds, you’ll need to consider at least a dual-band modem or higher. The Wi-Fi 6 wireless protocol will even offer nearly the same speeds that you’ll get when you are connected via Ethernet cable.

You’ll also want to consider the location of the modem, as certain modems are only capable of sending a signal so far. The 802.11n technology modems only offer 460ft of the wireless signal, whereas the more advanced 802.11ac offers 820ft. If you need more, you might have to end up buying a separate router or an extender of some sort.

Wired Ethernet Ports

Speaking of wired connections, these are something that is usually faster and more reliable. If you are going to be wiring in multiple devices to the DSL, you’ll want to make sure that the modem can support them. Most models come with one or two ports, however, all the ones on this come with at least 4. You’ll also want to consider the speeds of these ports. Some of these ports are capable of offering Gigabit-fast speeds, where some won’t make it past 100Mbps.

The Firmware

You’ll also need to access and upgrade your modem’s firmware from time to time. This is only something that can be done through vectoring upgrade firmware. Not having this capability could make your modem non-compatible. Just being able to stay in touch with your network’s settings in a nice feature. Being able to alter them is even nicer, but pertinent in some situations.

Remote Capabilities

Some people might need to allow multiple sources of Internet traffic to connect to their network. This is something that comes in handy for remote video conferencing, HD streaming, and other speed-based activities. You won’t have this kind of capability if you don’t opt for a modem that is CenturyLink Broadband Remote Access Server (CBRAS) compatible.

Security

Never invest in a modem without some kind of firewall of encryption software. The Internet is just too risky these days!

Price

At the end of the day, the goal is to save money. That’s the whole point of buying this extra modem, right? So, why pay $150 for a high-tech modem if you are only going to use it for a year? Consider how long you plan on using the modem and set your price based on that information.

Frequently Asked Questions on CenturyLink Modems

Which modems are compatible with CenturyLink?

Conclusion

You can see there are a lot of things to consider when choosing a modem for your CenturyLink connection. However, it is the connection speed along with the DSL technologies that are the most important. Just keep in mind that just because a certain speed is listed on the modem, it doesn’t necessarily mean that you’ll be able to achieve that exact speed.

Just like everything else in life, there are a lot of factors that can determine exactly how much speed your modem produces. If you are going to go with CenturyLink Internet, buying your own modem is without a doubt the way to go. Not only will you be privy to support around the clock, but CenturyLink will have step-by-step setup directions on their website.
