puma 6 chipset test

I am no longer seeing those 200mS spikes; jitter is ~10-20mS and remains this way. If so then I would tell them you want the broadcom Chipset modem as the Intel Puma Chipset has major latency issues and drops packets. You’ll find the newer Netgear – CM700 for about the same price as the 600, and it is capable of bonding more channels, but that model switched from a reliable Broadcom chipset to the newer PUMA 6 chipset. Overall Product Rankings. The 6 being the worst as far as I know. Intels Puma 6 Chipset is severely flawed and has modems simply dropping connections. I just recommend you avoid anything with it. Now it has been known for a while that these chipsets cause latency problems. Google, "List of Puma 6 Chipset", and look over a few different lists. You can run this test for puma based models. The Puma 6 chipset inside your Home Hub 3. View entire discussion ( 2 comments) More posts from the teksavvy community. is the puma 6 chipset flaw fixed: No, it can never be truly fixed, as its an actual hardware flaw, and it can never be fully patched out. The alternative being the puma 6 chipset which has been deemed a “bad modem.” Do not buy any modem containing the Puma 6 chipset. Installation Another tie. And if I’m not mistaken I think neither one of these modems have the puma 6 chip. It also affects the puma 4, 5, and now the puma7 chipsets as well. Do yourself a favor and look up this issue before you buy a 3.0 Modem. Take the Intel Puma 6 chipsets which are in some ONTs (optical network terminal) also known as modems. Its now come to light that the Arris SB6190 and Netgear SB700 cable modems have a flaw, and its chip the intel Puma 6, is seriously flawed. And the most troublesome problem is the random spikes of latency causing your internet speeds to come to a crawl. - BestReviews | Full review. This chipset is a very widely used chipset in cable modems, so if you've been noticing latency in your connection, you'd best test if it uses the Puma 6 chipset. Because different versions of the update are required to address multiple operators’ configurations, we are passing the individual releases on to operators as soon as they complete ARRIS testing. As Intel provides these releases, they immediately undergo rigorous testing for the ARRIS devices. Went though Comcast level 1, 2 and then 3. No, Puma 6 never gained all that much traction and some of its vulnerabilities were never addressed, like e.g. So you know for sure you have a Puma 6? But you have to be targeted for it to be an issue and is only really a problem if you do "fast twitch" gaming activities while targeted. This is not isolated to one chipset. However, Linksys modems still receive stellar reviews, so you have to give Linksys engineers credit for being flexible and thinking outside of the box regarding security issues. Both modems are a simple plug and play. Do you have a Intel Puma Chipset box? Unfortunately for all the pros of Virgin and its wonderful staff it is let down by the Home Hub 3, more specifically the Puma 6 chipset by Intel/Arris who have now made a Puma 7 chipset with similar issues. Ironically, the best way to test it is via a performance test cooked up at dslreports.com: It's performance is so consistently bad you can actually detect the chipset via its performance metrics. The other is just a story about the 5 & 7 Puma chips. It is flawed, and it is susceptible to DoS attacks and other hacks. Puma 6 is basically just adding a fair amount of jitter to your line, essentially the way the chipset on your modem handles processing things for multi-stream applications makes it not optimal, and will add a "buffer" of latency every now and again. It is generally thought they were not tested properly. ANyone with a PC.. Might even work virtually on a Apple. Intel has tried to provide a partial fix in firmware, but manufacturers using the chipset (such as Cisco, Hitron, and Arris) have been slow to roll it out. Intel Puma 6 … there's a DoS-vulnerability there that's pretty easy to exploit. I think the arris is a broadband chipset and the xb6 uses a puma 7 . There are numerous horror stories and there is a Class Action Lawsuit going on too. They told me that they cannot update the firmware on retail equipment as it could potentially cause damage to the modem. Spectrum doesn’t officially certify the CM700 for any faster speeds than the CM600 can transmit … The first is the person who found the issue that created a class action lawsuit. wrote: I have a similar story here. Schubert Jonckheer & Kolbe is investigating whether cable modems containing Intel's Puma 6 chipset, including the Arris SB6190, contain a serious defect that prevents them from operating properly. Inside the Arris SB8200 is a Broadcom BCM3390 chipset (a much needed change from the SB6190’s Intel Puma 6 chipset which had hardware bugs and caused them a lawsuit for good measure), 3GB of RAM, 128MB S34ML01G200TFV00 Spansion flash memory NAND and 16MB Macronix MX25L12805D SPI NAND flash memory. 1.
