Puma Modems Driver

Posted on by



Looks like my last modem upgrade happened just before Arris switched to Puma 6. Postpawl on July 6, 2019 My brother recently got a free modem from his ISP with the defective puma chipset and he ended up keeping it because the defect wasn’t that noticeable. I don't think the version of the E2251 that I have has PUMA chipset. I don't have any latency spikes or issues. In fact this modem lowered my latency! I did do the puma test and it passed. I think it's the RTL8125 NIC I'm using i switched back to intel at 1000baseT and getting consistent 950mbps down 50mbps up and lower jitter and cpu usage. Canon u.s.a.,inc.

Approved Modems Helpful Resources

Consumers today announced the filing of class action lawsuits against Arris International plc and NETGEAR, Inc., claiming that the companies sells cable modems containing a serious defect that results in high spikes in network latency, degrading users’ Internet connections. Contact us to learn more about your legal rights.

The lawsuits, filed on March 31, 2017 and April 14, 2017 in the U.S. District Court for the Northern District of California, allege that consumers who purchased Arris’s SURFboard SB6190 and Netgear's CM700 modems—which promised consumers reliable connections to the Internet—experience severe network latency spikes. Hundreds of users have complained in online forums, and Arris itself has even acknowledged the issue. Arris and Netgear, however, have failed to fix the problem for cable modem purchasers.

“Consumers paid top dollar for a high-end cable modem, but even Arris and Intel now acknowledges that these modems suffer from a serious flaw,” said Noah Schubert, a partner at Schubert Jonckheer & Kolbe, “Arris, Netgear, and other cable modem manufacturers shipping modems with the defect should recall the affected models and issue refunds.”

According to the lawsuits, the root of the problem is the cable modem manufacturers' decision to swap out the Broadcom chipset in their modems with the Puma 6 chipset from Intel Corporation. Arris told online technology websites that the problem stems from Intel’s Puma 6’s chipset, which causes cable modems to suffer from significant jitter and latency on their network connections. Reports on multiple websites and forums indicate that these cable modems suffer from 'latency jitter so bad it ruins online gaming and other real-time connections.' Intel has also confirmed the defect, stating that the company is 'aware of an issue with the Puma 6 system-on-chip software that impacts latency,' but after numerous months, it has failed to release any update that fixes the issue.

According to The Register, 'The problem appears to be that the x86 CPU in the modem is taking on too much work while processing network packets. Every couple of seconds or so, a high-priority maintenance task runs and it winds up momentarily hogging the processor, causing latency to increase by at least 200ms and, over time, about six per cent of packets to be dropped. It affects IPv4 and IPv6 – and it spoils internet gaming and other online real-time interaction that need fast response times.'

Even users who do simple web browsing may be affected by the momentary high spikes in latency, causing websites to feel sluggish or not load.
