A reliable modem offers a secure, stable internet connection so that you can browse the web, work, play games, stream movies, and more. If you don’t own a modem or are looking to update an old one, you’ll encounter many models with distinct specifications. For digital subscriber line (DSL) internet, you’ll be looking at ADSL and VDSL modems—which support different internet speeds.

In this guide we’ve considered various factors and reviewed a variety of DSL modems to help you choose the best DSL modem for you and your needs.

Factors to consider when buying a DSL modem

Before buying a DSL modem, it’s important to determine whether the device is compatible with your provider. Some of the top DSL internet providers in the US include Frontier, CenturyLink, AT&T, Windstream, and Verizon.

Although DSL doesn’t offer the fastest internet speeds around, it does provide service to rural areas that other options may not be able to reach. Also, DSL internet tends to be a more affordable choice that can serve the needs of smaller households with light internet usage.

So what else do you need to know to choose the right DSL modem? Modem types, ports, compatibility, and security are essential considerations.

Types of DSL modems

There are two types of DSL modems: ADSL and VDSL. ADSL stands for asymmetrical digital subscriber line and is an older technology that allows internet users to receive data via a telephone line. On the other hand, VDSL, which stands for very high bit-rate digital subscriber line, is a newer technology that delivers faster connection speeds than ADSL.


You should always check the number of ports available on a DSL modem to determine whether it accommodates all of your devices. It generally makes sense to go for a modem that allows for more simultaneous wired connections.


Not all modems are designed to be compatible with all internet provider’s services. Check the modem sales page for companies the modem is compatible with, or contact your internet service provider (ISP) and ask for device recommendations.


With the rise in hacking and other internet crime, security is a serious factor to consider when buying a modem. The right device should protect your personal information and Wi-Fi. For the best protection, you should look for a modem that has at least a firewall and WPA/WPA2 encryption.

Best DSL modems

When shopping for DSL internet service, you will find that some DSL providers offer modems that work exclusively with their networks. While some of these modems are among the best devices offered for DSL internet, choosing one of them limits you to using a single ISP. If you expect to move or switch providers, that may not be the best option.

The good news is that trusted technology manufacturers offer DSL modems with a wide range of performance levels and price points. You can familiarize yourself with those options to get an idea of what you need, but checking for compatibility with your ISP is a must before you buy.

Frequently asked questions (FAQs)

What does DSL mean on a modem?

DSL stands for digital subscriber line. This means that the modem connects devices to the digital subscriber line provided by your internet service provider.

What is the difference between a DSL modem and a cable modem?

The main difference between the two modems is that a DSL modem unit is hooked up directly to your phone line. On the other hand, a cable modem connects to the service network through a coaxial cable.

How much can I expect to pay for a DSL modem?

Some providers rent out their DSL modems for a monthly fee of between $5 and $10. If you prefer buying a device over renting one, expect to pay between $50 and $150.

Why is my DSL modem light blinking?

Checking your device’s user manual is the best way to understand what the lights on your modem mean. However, if you notice a light on your DSL modem flashing, that likely signals that it is trying to sync with a network.

How do I fix a blinking DSL modem light?

If your DSL modem light is blinking, there are several steps you can take to address the issue. Here are common fixes you can try:

  • Check the cables. The first thing you want to do is check the connectors and cables, especially the DSL cable. You should confirm that the DSL cable is firmly connected to the correct port.
  • Restart the modem. If the problem remains unresolved, you can turn off the modem for a few minutes and then turn it back on. If your modem has a battery, you should remove it before disconnecting the modem and put it back before reconnecting the modem to the power source.
  • Contact your ISP customer support. If neither of the above works, you should contact your ISP’s customer support and they should be able to help you troubleshoot the problem.

How do I know my DSL connection is working?

There are several ways to determine whether your DSL is working or not. These include:

  • Access the modem’s settings by typing the IP address indicated in your device’s manual. Most DSL modems provide the ability to test their own line from within the modem. This way, you can easily diagnose an issue in your modem or DSL line.
  • Contact your ISP’s technical team to test your modem from their side of the connection. ISP technical support teams have the tools and skills to test your modem’s connection and speed from their end. Once they diagnose an issue, they can help you resolve any issues and get your device in optimal working condition.
