DSL modems are devices that convert digital signals from your ISP into analog signals to send over the phone line. They also convert analog signals from the phone line back into digital signals for your computer. We will present the difference between a DSL modem and a router and the three best devices in the market.

What is DSL?

DSL, short for “digital subscriber line,” is an acronym used to describe a type of data connection that utilizes phone lines. DSL connections are most commonly sold by companies specializing in landlines. Often, when you are using a landline phone with DSL, an adapter is required to split the port and plug in both devices.

DSL modem VS. router

You’ll need a DSL modem to use the internet, which establishes the connection to your home or office for data traffic. A router is optional but can be helpful if you want to set up a wireless network at home and use your devices without being connected. A router lets you connect multiple devices to your modem for a faster, less cluttered connection. You’ll need a router depending on what you need it for. DSL is a type of internet connection, while Wi-Fi is a device that moves data across the connection. Rather than buying two separate devices, you can often get a combined modem+router service from your internet service provider.

How to Choose Which DSL Modem Fits Your Internet Service Needs?

DSL modems are a modem that connects a home or business to a telephone line, which connects the customer to an Internet service provider. There are two types of DSL modems: internal and external/ ADSL2+ and VDSL2. Internal DSL modems connect directly to a computer’s motherboard, while external ones plug into a USB port. 

External models can be moved quickly from one computer to another, while internal ones must be installed when you buy your computer or install your operating system. The best way to choose which DSL modem fits your needs is by looking at the following factors: speed, price, and compatibility with your ISP.
