7 Best DSL Modems for CenturyLink [Approved & Compatible]

If you receive your Internet service from CenturyLink and need to replace the modem, you will want to make sure the new modem is CenturyLink compatible. DSL stands for “digital subscriber line”, and a DSL modem allows you to connect computers to the Internet with a faster connection than dial-up, using a data subscription plan from a cable company. Though modems are often provided by the cable company, they can also be purchased from a third-party seller. This article will help you find the best DSL modems for CenturyLink.

How do I choose a DSL modem for Centurylink?

Built-in Router- One thing to consider when purchasing a modem is whether it has a built-in router, or is just a modem. If you buy a modem/router combination, you will likely end up spending less than you would if you bought a modem and a separate router. It also saves you the trouble of having to set up two different devices. On the other hand, routers tend to have much more technological improvements than modems.

If you want special features in a router, it might not be worth it to buy a modem/router combination. It would be cheaper, in the long run, to have a dedicated modem and keep replacing the router than it would be to keep replacing a modem/router combination. So whether you want a modem with a built-in router or a modem by itself will be largely dependent on how fancy and up-to-date you want your router to be.

Speed Support- You need to look at what speeds are supported by the modem you are considering purchasing. You want the maximum speed supported by the modem to be equal to or greater than the speed of your subscription. It would be silly to pay more each month for fast speeds that you never reap the rewards of.

Service Compatibility- Of course, the modem you purchase will need to be compatible with CenturyLink. It also needs to be compatible with the particular type of service you have. The perfect modem would support ADSL, ADSL2+, VDSL2, and pair bonding. If you have a specific kind of service, such as fiber optic, for instance, be careful that you make sure it is supported. You wouldn’t want to spend money on a modem that doesn’t work.

Upgrade Compatibility- When purchasing a modem, you will want to make sure it isn’t out of date. What you want is for it to be compatible with all available upgrades, as well as future ones. Otherwise, you will have to buy a new modem in the event that your service provider comes out with an upgraded plan that offers faster service. Make sure the modem you buy is up-to-date and future compatible.

Usage- How much you plan to use the Internet makes a difference to what sort of modem you will need. How many devices do you plan to connect to the Internet? If you want to connect a lot of devices, you should make sure the modem has Ethernet connections rather than only USB ones. It also matters what you will be doing online. If most of what you do is casual browsing, you won’t have the same need for faster speeds as someone who does a lot of heavy gaming or video streaming.
