Do Not Buy Intel Chipset ModemsIntel’s Puma 6 chipset included in several cable modems is defective as it allows high spikes in network latency quite often (slow web page loading, for example).
These severe network latency spikes interfere with online gaming, streaming video, or simply surfing the web. Network jitter (variable latency) also causes problems.The Puma 6 modems suffer from both latency and jitter.
Some firmware updates have only temporarily fixed the problem and it seems Intel has no real fix for the issue. Consequently, these bad internet connections landed cable modem maker ARRIS in trouble with a pending lawsuit filed in California.Puma 6 Defect LawsuitThe Schubert Jonckheer & Kolbe law firm has begun an investigation into the issues and has filed a class action lawsuit for consumers of affected modems.
If you own one of the affected modems (listed below), you can file your issues and get alerts to any possible legal action against Intel and the cable modem brands (particularly ARRIS).
On the Schubert Jonckheer & Kolbe Puma 6 Chipset Defect page, you can check out the full lawsuit details.Easiest Way to Spot a Defective Puma 6 Modem.
See this Intel logo on a modem package?
Avoid buying these potentially defective modems.Looking at the cable modem package is the easiest way to find if a modem is potentially defective. If you see an Intel logo on the box, stay away from it. Reports of the Puma 7 chipsets may also be defective, so the best thing to do is avoid any cable modem with Intel inside.Note: not all Intel Puma chipset modems will have an Intel logo on the front of the modem package.
Some bad modems like the NETGEAR CM700 and NETGEAR C6300 do not have Intel logos on the front of their modem packages. Therefore, read the Intel Puma 6 modem list below to avoid purchasing a possibly defective modem.
While Intel has issues with the Puma chipsets, Broadcom chipsets (produced by Broadcom Inc.) suffer no troubles at all. For example, you can feel safe using a modem like the ARRIS SB6183 or NETGEAR CM600 as they use a Broadcom chipset.

NETGEAR CM700 is a modem missing on this list? Please leave a comment below.Intel Puma 6 Modem List Chipset Defects ReactionApprovedModemList.com will no longer recommend any Intel Puma 6 cable modem on this site. However, to show complete approved modem lists for each internet service provider, modems listed for each company may contain bad modems too. ApprovedModemList.com will display warnings for potentially defective Puma chipset modems.While one of the Do Not Buy modems may work fine for your use, using a device known to have a serious issue involves risk. The cable modem may work properly for a few weeks and then problems could occur later. Skip any potential problems now and go with another approved cable modem for your internet service provider (without Intel inside).
