Intel Puma 6 Modem Chipset Defects [List]

Intel Puma 6 was a chipset with a hardware flaw used in many cable modems. The defect leads to latency spikes which cause slow loading speeds. It interferes with video streaming, video gaming, and browsing web pages.

The defect causes intermittent issues. Sometimes your internet will work fine, and other times it will load slower than dial-up internet.

We’ve personally tested modems with the defect to learn all we can about it.

This, so we can share all you need about what the Intel Puma 6 Chipset is, and what it can do to your network.

Let’s get started.

What is the Intel Puma 6 Chipset Defect?

In 2016, Intel released its Puma 6 high-speed modem chipsets. Many modems incorporated these chipsets. After its release, there were several reports of network issues with modems using the chipset. [1]

A chipset on a modem works with the memory, processor, and other components to control communication. 

What Does the Defect Cause? 

The Puma 6 chipset defect is a hardware issue that causes latency jitter. This variable latency causes:

  • Slow loading times
  • Latency spikes lead to extreme lagging in online video games
  • Poor video call loading
  • Other real-time connection difficulties

There might be some modems missing, but I didn’t want to put any modem which I’m unsure about here. If you know any more modems with the chipset, please let us know in the comments below.

Intel Puma 6 Chipset Security Issues

Besides the latency problem, the Intel Puma 6 chipset has security concerns too. It has a weakness that exposes it to outside attacks.

For example, let’s say an attacker gets your IP address. In that case, they could remotely slow down your network or disable it entirely. This same vulnerability is also present on the Puma 5 and Puma 7 chipsets. 

However, Intel has addressed these issues with firmware updates. So, if your modem is up to date, it should no longer have these security vulnerabilities. 

Intel Puma 6 Call-Action Lawsuit

Schubert Jonckheer & Kolbe, a class-action lawsuit law firm based in California, is investigating the Puma 6 Chipset defect. [2]

Let’s say you have an Intel Puma 6 chipset modem with variable latency and poor internet performance.  In that case, you may be entitled to a full refund of your purchase price. 

For more information on the potential lawsuit, visit the Shubert Jonckheer & Kolbe Puma 6 webpage. 


Modems with the Intel Puma 6 chipset can experience variable latency, making your internet unusable. If you have a modem in the list above, replace it with a new one. There is no update or fix available since it is a hardware flaw. 

If you did purchase a modem with an Intel Puma 6 chipset, you may be entitled to a full refund. Contact the retailer you bought it from; they might allow a refund. Or submit your information to the class action law firm.
