CenturyLink, one of the leading DSL and fiber internet providers in the United States, has gained praise for its services. However, the one thing that doesn’t sit well with us is the fact that they’re currently profiting from renting out modems to customers already paying for their services.
While it may seem convenient initially to depend on your ISP for networking equipment, the rental can be quite costly in the long run.
Finding a suitable modem can be challenging, considering the various options in the market. It’s also important to note that not all modems are compatible with every service provider, adding to the complexity. However, suppose you’re specifically looking for a modem that works well with your CenturyLink internet connection. In that case, you’ve landed in the right place.
We’ve tested and compiled a list of the 5 best CenturyLink modems here to simplify your decision-making process.

How we Picked And Tested Best CenturyLink Modems?
For selecting the best CenturyLink modems, we followed a meticulous testing process to ensure our readers receive accurate and reliable information. Our first step involved researching to identify the popular and highly recommended modems available in the market.
That’s why we put a lot of effort into researching and choosing products for our reviews. We want to ensure we recommend things our readers will truly enjoy. First and foremost, we aimed to include products at price points so that there’s something for everyone regardless of their budget.
We also considered factors like internet speed and bandwidth as to whether it offers dual or single-band WiFi. Additionally, durability and cyber security were important factors because staying safe online is crucial, especially if you spend significant time online.
Once we had compiled a list of contenders, we moved on to the testing phase. We tested each modem under real-world conditions. Our testing covered download and upload speeds, latency, signal strength, and stability.
Moreover, considering the consumer’s technical know-how, we tested how easy it was to set up the modems and their user-friendliness. After conducting a thorough analysis and comparing all these factors, we determined which modems stood out as the top choices for CenturyLink users.
Things To Consider Before Buying A Modem For CenturyLink
When shopping for a router, it’s important to consider the features and crucial factors. With the wide variety of routers and models available on the market, I’ll simplify things for you and guide you in researching and finding the one that suits your needs.
Internet Speed
Firstly, determine the internet speed provided by your ISP (Internet Service Provider). Find out if you’re on a CenturyLink plan that offers speeds up to 100Mbps or if you have their Fiber Gigabit plans with speeds up to 940Mbps. You can check this information on their website at https;//www.centurylink.com/home/internet/. To be sure about the speed in your area, call them and ask about it. Once you have clarity on your internet speed, select a router that can handle that speed or higher.
Wireless Standards
Another aspect to consider is the standards supported by routers. These standards include 802.11b (WiFi 1), 802.11a (WiFi 2), 802.11g (WiFi 3), 802.11n (WiFi 4), 802.11ac (WiFi 5), and the latest standard, which is 802.11ax (WiFi6).
If you want a router opting for WiFi6 would be ideal; however, remember that WiFi6 routers require compatible devices to benefit fully from their features.
In addition, WiFi 6 routers offer a speed that is three times faster than WiFi 5 routers. It makes them capable of managing crowds due to their higher theoretical speed, reaching up to 9.6Gbps.
However, I suggest opting for a router that follows the ‘ac’ wireless standard, as it is widely preferred and can easily handle CenturyLink’s fiber plans. Moreover, WiFi 5 routers tend to be more affordable when compared to WiFi 6 routers.
How Many Devices Will be Connected At a Time?
If you live alone, you probably don’t have a lot of devices connected simultaneously. I only connect my gaming console, laptop, and TV. So it doesn’t put much strain on my router.
However, suppose you’re someone who uses more devices. In that case, it’s important to choose a router with a core processor, extra ports for wired connections, and even USB ports for adding external drives.
WiFi Coverage
Determining the coverage area is crucial. If you want all your devices to have connections throughout your home, investing in a good router that covers the entire space is necessary.
For apartments or homes, a budget-friendly router can fulfill your needs without any doubt. If you live in a house or a larger area opting for a high-end router with extensive coverage becomes essential.
When it comes to covering thousands of feet effectively, regular routers won’t suffice. You must consider investing in a mesh WiFi system.
