DSL vs. Cable Internet: Overview

As noted above, DSL is an abbreviation that stands for Digital Subscriber Line. It uses an advanced modulation scheme to transmit internet data through a pair of copper wires for mobile phone networks. Sometimes experts refer to DSL as the last-mile technology since it connects telephone switching stations to households and offices. The main DSL categories available for home subscribers are DSL and ADSL.

Cable internet, on the other hand, is a broadband connection transmitted through local TV cables connected to a modem. Since the coaxial cables used for TV provide greater bandwidth, cable internet can achieve much faster internet speeds than DSL. This factor, and the reality that most households already have cable TV, makes cable internet the preferred option.

DSL vs. Cable Internet: What Are the Differences?

Price and Value

DSL and cable internet offer different values and pricing points. Typically, DSL is much more affordable than its counterpart, making it ideal for people on a budget. Therefore, it allows you to save while accessing solid internet speeds for primary uses such as web browsing, light streaming, and emailing. 

Cable internet also has affordable options that match DSL. However, these options also offer much faster speeds that are more reliable than DSL plans. Therefore, if you are looking for affordable internet options with faster speeds of up to 100mbps, cable internet is the way to go.

Availability

If you live in suburban and urban areas in the US, your internet is likely cable internet. Cable internet is hugely available in these areas because it runs on existing cable TV lines. Therefore, with numerous coaxial TV cable lines available in these areas, installing cable internet rather than DSL is significantly easier. 

In contrast, Digital Subscriber Line provides internet connection via landline phone lines, making it the most common internet type. Although it is the most common, it is not the most popular due to its speed limitations.

Internet Speeds

Cable transmission provides much higher internet speeds compared to DSL. These speeds allow you to stream and download large amounts of data without any challenges. Typically cable internet connection can deliver maximum rates as high as 1.5Gbps. 

Such speeds are more than most households need. Therefore, the ideal plans range between 100-300Mbps. These plans provide a unique combination of speed and affordability, making them suitable for most homes and online gaming.

In contrast, DSL has maximum speeds of between 75-100Mbps. While these speeds are okay for simple tasks such as web browsing and light streaming, they can’t handle more complex tasks. You can get cheap DSL plans for basic household uses with speeds starting as low as 6Mbps. Cable internet also offers faster upload speeds than DSL. However, both options provide upload speeds of at most 30Mbps. 

Reliability

While cable internet offers much faster speeds, its reliability is the factor that sets it apart from its counterpart. Both internet connections can experience slowed connectivity, but cable internet is more manageable than DSL. That means cable internet connections are much more reliable.

One of the main issues that often slows down cable internet is online traffic within the neighborhood. Therefore, peak usage times, typically between 5 and 10 pm, often include slower internet speeds. One of the ways to solve this issue is to get internet packages with higher rates so that it remains reliable even during peak use hours. Other measures include:

  • Scheduling large downloads for early morning or overnight
  • Regulating the number of devices connected to your network
  • Using ethernet cable instead of Wi-Fi
  • Installing additional Wi-Fi extenders to your network

On the other hand, DSL reliability issues are not as manageable. Often these issues result from the extended distance between your home and the internet hub. The further the phone lines travel with DSL internet to your home, the more unreliable the internet connection. This unreliability makes DSL internet a risky option, especially if you are unsure where your connection originates.
