5. Best ADSL Modem for Centurylink: Actiontec GT784WN

If you are seeking a more affordable combo for the low-level CenturyLink internet plans, the Actiontec GT784WN is the perfect product to invest in. Keeping the complications of Fiber compatibility and VDSL support aside, this product from Actiontec is strictly ADSL compatible and even ensures decent wireless speeds in case you also plan on getting a router along.

Speed & Channel Bonding

Coming to the speeds, this product supports maximum data transfer rates of up to 300Mbps. However, from a practical perspective, you can expect it to work perfectly for speeds reaching up to 24 Mbps, making quite a strong case for the 20 Mbps plans from CenturyLink.

Conclusion

For the given price, there aren’t many products as inclusive as the Actiontec GT784WN. While this device has a lot going for it, the smart antenna’s availability steals the show by offering excellent coverage to get rid of any dead zone in play.

6. Best Budget Option: ZyXEL P660HN-51

Getting hold of a budget ADSL modem isn’t easy as these innovative devices are extremely rare. However, you can always rely on the Zyxel P660HN-51 as your choice of CenturyLink ADSL modem. It features on the list courtesy of the advanced security safeguards, which are even better than the GT701D from Actiontec.

Speed & Channel Bonding

Coming to the speeds, I tested this ADSL2+ modem with a 100Mbps internet plan from CenturyLink, only to find that it can easily assume download and upload speeds of 80Mbps and 10Mbps, respectively. While this doesn’t make it the best modem for CenturyLink right away, it still is one of the better picks for the low-level plans offered by the ISP.

As far as the tech is concerned, it supports ADSL and ADSL2+ connections but lacks support for a GPON port to lead into fiber connections.

Ports and Connectivity

There are 4 high-speed Ethernet ports, each capable of reaching wired speeds of up to 100Mbps or less. One out of the four ports is an optional LAN/WAN port allowing you to connect the device to a routing setup or a console, as preferred. There is also a standard DSL port that feeds data packets to this gateway of a device.

As discussed in my dedicated review of the ZyXEL P660HN-51, this DSL modem for CenturyLink also has routing capabilities, featuring Wi-Fi N standard with 2.4GHz and a tad weaker 5GHz band support.

Design and Build

This piece of tech measures 1.57 x 5.2 x 7.4 inches, making it a lot slimmer than those cable internet modems. Made of plastic, this product is quite robust, comes equipped with several heat-dissipating vents, features a vertical structure, and, most importantly, weighs 0.83 pounds.

Hardware and Performance

While the company hasn’t declared the exact chipset in play, the performances are synonymous with a standard multi-core processor. As tested, latency is hardly an issue with this ZyXel device. It also comes with ubiquitous security safeguards in firewall and VPN support.

Conclusion

If you are searching for a DSL modem for CenturyLink to pair with their mid-range plans, I’d recommend the Zyxel P660HN-51. And purchasing it makes sense for a standard household owner, who also needs to keep an eye on the external online threats as this gateway scales beyond every other product on the list in terms of security tweaks in play.

Note: Once purchased, you can install CenturyLink internet on your own and save the hefty installation fee charged by the ISP.

Things To Consider

If you’re still not sure, here are a few things you should consider when getting an ideal modem/router for CenturyLink:

• Ensure that the modem or modem/router combo you’ve chosen is compatible with Centurylink.
• Like I said above, Choose the modem depending on the type of connection, if you’re having a DSL connection at your end then get a compatible DSL modem and if you’re having a fiber connection, get an optic fiber modem.
• The modem you’re choosing should be capable of handling the speeds of your internet plan (you can’t expect a 200 Mbps modem to handle gigabit internet speeds or higher speeds.)
• Also, most Centurylink-approved modems are gateway devices that also double as routers. While setting them up is easier than setting up separate devices, the performance is better in the latter.
• So, if you want better performance and can spend a little more to buy a wireless router, I’ve also made a list of the best Centurylink routers.

A Beginner’s Guide To Find An Ideal Modem Compatible with CenturyLink

Now that you know what modems work with CenturyLink, here are some of the factors to keep in mind while picking one perfect for you.

User Requirements

If you want to pick a modem for Century Link, you should first prioritize the speed-based requirements. If you only have a few devices to connect to the internet, a standard 50Mbps or a 100Mbps plan works great. However, if you are a gamer, gig or any mid-range plan (around 300Mbps) makes perfect sense.

You can pick a device that makes sense based on these speed-related requirements. For instance, if you are a frequent traveler who needs to juggle DSL and Fiber-based internet plans, a modem with a GPON port makes sense. Also, depending on the connection you choose (ADSL, ADSL2+, and VDSL), you can pick a modem that supports either one or all of these.

Speeds and Compatibility

As the preferred ISP, CenturyLink offers multiple selections when it comes to plans and internet speeds. For instance, you can choose an xDSL modem to pair with four handpicked plans, including 100Mbps, 40Mbps, 20Mbps, or 10Mbps.

If you plan on using the 940Mbps internet plan from the ISP, you can look for a modem with DSL and fiber-specific GPON capabilities.

Also, if you want to ditch the router and get a combined device, the likes of Zyxel ADSL2+ gateway devices make sense, offering Wi-Fi support and other routing capabilities.

Also, If you have less faith in DSL internet, CenturyLink will soon give you a more inclusive taste of fiber-grade speeds. Till then, you would have to make peace with DSL, primarily if you hail from a rural locale. Plus, CenturyLink uses the elusive ‘Fiber to the Node (FTTN)’ support for minimizing the distance between copper lines, which does a decent job of keeping the speeds up.

Hardware and Performance

Not many users pick a gateway looking at the internal setup. However, if you are the one who chooses differently, always opt for a device with a multi-core processor and 128MB RAM, provided the OEM declares these details.

As far as the performances are concerned, the gateway you choose should be able to offer built-in Quality of service and the required security safeguards to prevent miscreants from accessing the data. As for streaming, you might want to consider high-speed internet plans, like the 100Mbps offering from CenturyLink, and then the performances will be top-notch.

Design & Build

If you plan on choosing a gateway keeping the structural aspects in mind, prefer a good-looking device with an adequate number of LEDs for status reporting. Also, heat-dissipating vents on the sides are important as that would cause overheating. Finally, going light and slim is necessary if you do not want the device to take up a lot of space.

Frequently Asked Questions

Verdict

Purchasing a DSL modem that supports CenturyLink from the above list is advisable unless you want to overburden yourself with those recurring rentals. If the selections still feel a tad overwhelming, provided you are migrating from cable to the DSL-Fiber space, here are certain goal-specific choices to work with:

• Invest in the GreenWave C4000XG if you have privileged access to CenturyLink Fiber. It has the best aesthetics and powerful Wi-Fi routing performance.
• For office and home-based setups that need IP calling support, the CenturyLink C2100T is a handy choice.
• Finally, if you seek an affordable DSL modem for low-speed plans, the ZyXEL P660HN-51 is a good choice.

You can even consider other options depending on the price you are willing to pay and the security specs you want to incorporate within the home or office network.
