Who Should Buy a DSL Modem

  • DSL subscribers – The type of internet subscription you have will dictate the type of modem you need. DSL subscribers will need a DSL-specific modem.
  • Budget-conscious folks – If you want to avoid the ongoing monthly rental fee associated with renting a modem from your ISP, purchasing your own modem is a smart move.
  • Those wanting an all-in-one solution – There are many DSL modem/router combos available, which make setting up a home networking solution easier than ever before. If you want the simplicity of an all-in-one solution, upgrading your current DSL modem to a modem/router combo may be a good option.

Who Should Not Buy a DSL Modem

  • Cable subscribers – As mentioned previously, the type of service you have will affect the type of modem you require, which means that cable subscribers will have no use for a DSL modem.

Research Tips

Here are some tips and best practices to consider when purchasing a DSL modem. Be sure to do adequate research on the product you are considering purchasing to look for must-have features and any additional options that meet your needs. You can also ask your friends, family, or DSL service provider if they have any recommendations on DSL modems for your home.

  1. Check the ports – The more LAN ports your modem has, the more devices you’ll be able to directly connect to it. This allows those devices to have a faster connection.
  2. Look for DSL types – Today’s DSL modems are largely ADSL models, or asymmetric DSL modems, which means the upload and download speeds are not the same.1 This is fine as download speeds are typically much faster than upload speeds. There are also DSL modems that handle VDSL, or very high bit-rate DSL.2
  3. Lightning protection is a big plus – Look for a DSL modem that offers lightning protection. This feature allows you to avoid damage to your modem in the event of a thunderstorm.
  4. Consider provider compatibility – You want to ensure that whatever modem you purchase is compatible with your service provider, so be sure to read the fine print or contact your ISP if you’re unsure about a particular device.3

How Much Do They Cost?

Between $100 and $200

For most DSL modems, you can expect to pay between $100-$200 and still get a quality product. Your DSL provider may offer a monthly rental for their own modem, but if you want to eliminate this ongoing monthly fee, purchasing your own DSL modem is recommended. However, the best of the bunch will cost you upwards of $300.
