5 Things They Don’t Tell You About DOCSIS 3.0 Modems

September 21, 2022

As far as cable modem technology goes, DOCSIS 3.0 is very old technology.  You will see DOCSIS 3.0 modems still available to purchase, but they are not the latest DOCSIS modem technology, DOCSIS 3.1 is. If you were looking at a DOCSIS 3.0 modem to buy, here’s what you really need to know.


Is DOCSIS 3.0 obsolete?

Knowing if DOCSIS 3.0 is obsolete or end of life (EOL), requires a quick look at their definitions:

Obsolete – When a product becomes obsolete, the manufacturer no longer provides updates to that product or the product typically becomes out of date because of a newer technology.

End-of-Life (EOL) – when a product a product is at the end of its useful life, so the vendor stops marketing, selling or reworking to sustain it.

Having this information, DOCSIS 3.0 is obsolete.  But some manufacturers are treating it as EOL, and it is soon to be unsupported equipment.

Here are 5 things to know about DOCSIS 3.0 that support its obsolete status:

  1. DOCSIS 3.0 was released in 2006, making it over 15-years-old. That is ancient in the technology world.
  2. DOCSIS 3.0 does not have all the improvements and new features of DOCSIS 3.1.
  3. DOCSIS 3.0 will not handle the faster speeds Gigabit that your Internet Service Provider (ISP) will be introducing in the near future.
  4. DOCSIS 3.0 outdated security protection and is not as strong as certified DOCSIS 3.1 modem
  5. DOCSIS 3.0 modems are viewed as end-of-life (EOL) by many ISPs today.


If you can purchase your own cable modem or gateway, we recommend purchasing a DOCSIS 3.1 modem. This will ensure your modem can deliver the Internet speeds that you subscribe to, today and in the future. Plus, a DOCSIS 3.1 modem will provide you with stronger modem security and greater speed performance for your entire Internet connection because it’s the latest technology.
