Tips For Buying A New Cable Modem

  1. When buying a new cable modem, you should always do just that, buy a new one.  Used modems are often returned because the provider cannot activate it. Most of the times the modem is registered to another provider or user and can't be undone. Some used modems actually belong to cable companies and are reported as stolen often times as well.
  2. Always buy from a reputable seller, such as directly from Amazon or authorized third-party sellers. This ensures that you will be able to register any equipment for warranties and/or replacements shall any issues arise.
  3. Be sure you are at least getting a DOCSIS 3.0 approved modem. This is the most widely used form of DOCSIS today. However, DOCSIS 3.1 is starting to take off too. Most companies require a 3.0 or higher these days. Anything less will hinder the speed of your internet. All featured on this site are 3.0 or higher.
