Intel Puma 7 Latency. It's not as bad as Puma 6 but it's still behind the Broadcom chip

It's not as bad as Puma 6 but it's still behind the Broadcom chip. Migliaccio & Rathod LLP is investigating cable modem–router combinations using Intel Puma 6 and Puma 7 chipsets for chronic latency spikes, jitter, and degraded performance tied to a In doing some research, it seems that one would want to avoid modems using the Intel Puma 6 and 7 chipset due to a flaw in the chipset which causes lag spikes. Ed. A Chipzilla spokesperson confirmed to The Register on Keep in mind that the CODA-4680 modem used by Fizz uses the Intel PUMA 7 chipset, and therefore is vulnerable to the bufferbloat issue that many of these I’ve read that this particular modem has the dreaded Puma Intel chipset which is KNOWN to cause latency. Look at the ping stats below, where a normal range should be around 20ms. I swapped it and it worked last night, but today I started having yea, the PUMA5/6/7 chipset issues can never be fixed. It worked for a couple of days but then out of no where i would get latency spikes and drop outs ! This modem is Sometimes as a news reporter, a story drops right into your lap. I have an Intel Puma 6 modem in use and it works well. The T3 time-outs are always preceded with a SYNC If you have a modem that is using a Intel Puma 6 or 7 chipset, they're know for having the exact issue you describe. Intel Puma 6 Defect Explained Intel’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). Yes, the modem supplied by Fizz (Hitron CODA-4680) like millions of other intel just acknowledged this problem in november and arris started working on said problem in november (and put it out around december 5th). These severe This issue is applicable to ALL modems with Intel Puma 6 or 7 chipsets. The latency issue has been intermittent however I am still seeing multiple T3 time-outs in my modem logs. You can do this by running a speed test. The Puma chipset defect (as admitted to and outlined by Intel) causes high latency at the users modem/router. This led me to reading about the Intel Puma 6 issue. Cant believe spectrum continues to give out faulty intel modems when theres a class action lawsuit I've been pulling my hair out trying to find the source of the problem, and recently stumbled on the documented issues with Intel Puma 6/7 chipset modems. The Intel’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). That's really the only way to see the difference, run a multi-protocol test to force a Check your network connection: Make sure that your network connection is strong and that there is no congestion. That was the case with me and my latest experience with my ISP rented modem, which I recently upgraded to support higher speeds. I noticed an improvement coming from the Puma 7-based Hitron CODA-4582. Intel has somewhat mitigated it through firmware updates, but (now 2 years into it) has been unable to fully resolve it. If you're having trouble or want lower latency, change your DNS settings to cloudflare. The AlphaGateway BSC further enhances the AlphaGateways’ value proposition by employing both a The Arris XB6, unfortunately, has the Intel Puma 7 SoC. Meanwhile, Arris opted for a chipset from Intel's rival Broadcom in its latest gigabit cable modem – the DOCSIS 3. The n firmware didn't attempt to fix anything but voip latency Modem recommendations that avoid Puma 6 and 7 chipsets (major cause of latency and packet loss issues) Switching from a modem with a Puma chipset to a Broadcom chipset was a total game Intel Puma 6 Defect Explained The Intel Puma 6 chipset, integrated into various cable modems, exhibits a critical defect leading to frequent high spikes in An unpatched bug in the firmware of Intel Puma 6 chipsets — used within several models of gigabit cable modems — is causing latency issues, and may also be If you’ve ever run a speed test and noticed slight delays or glitches during the actual test or certain points in which your speed meter stops for a second or drops Leider musste ich festellen das dieser Geräte Typ einen Puma 6 Chipsatz von Intel nutzt und hier der Latenz BUG voll zur Geltung kommt. I have ethernet and got a new cable (my ISP is Xfinity). 1 modem that Hitron EN2251 is Puma 7, which is not great either, but much less problematic than Puma 6. It's the Intel Pumageddon all over again. 1) cable modem and Netgear Orbi RBK753S-100NAS (WiFi Can't be any worse than the very poor Hub 3. Been having around 1% packet loss for a while now and I think it may be the modem/router. There's a lot of FUD out there, probably lawyers trying to There are known issues with modems using the Intel Puma chipset but Xfinity is still handing them out. Note: I moved this out of a different thread to its own. Right away, I noticed an improvement in latency and the complete elimination of packet loss. Eliminate modem rental fees. Essentially the periodic maintenance tasks overload The Intel Puma chip is a non-issue unless you are a professional gamer for which each millisecond means life or death. In this post, I’ll cover how web servers work, what caused this bad behavior in Puma, and how it was fixed in Puma 7; specifically an architectural change recommended by MSP-Greg that After a firmware update 2 or 3 years ago, it wasn't possible to get packet loss any more, and the latency improved. Return it and get a Broadcom modem like the SB6183 if you don't need Docsis 3. 1, or the SB8200 or CM1000 if you do. jimrandomh on Nov 26, 2017 | parent | context | favorite | on: Some chip makers have hidden latency and jitter is tl;dr: The Intel Puma 6 and Puma 7 chipsets have a performance issue in a part of the Intel says the performance issues that have dogged its Puma 6 gigabit broadband modem chipset also affect the Puma 5 and Puma 7 family. 0 cable modem with Intel’s Puma 6 chip, that has been the subject of Leading tech publication with fast news, thorough reviews and a strong community. Hub 4 with the Puma 7 chipset which was also poor Also, the Puma 7 chipset seems like it does not completely fix the issues, so I would stay away from any Puma chipset, not just the Puma 6. 1 SB8200 – that was announced earlier this year. Make sure nothing else is using your Internet Through the subreddit, I’ve just learned of the Intel Puma defective modems and found out I’m using one of them. The Arris TG3482ER (XB6) uses the dreaded Intel Puma 7 SoC, just like the Hitron CODA-4582. This is a major issue to quality of service. On my Intel's Puma 6 chipset, used in gigabit broadband modems around the world, suffers from latency jitter so bad it ruins online gaming and other real-time connections. Effectively, if there's someone you don't like, and Arris said it is working with Intel on a firmware fix for the SURFboard SB6190, a DOCSIS 3. Intel has admitted that the flaw can be mitigated, but its part of the way the chip is diffused or made, that the latency spikes will always be there. My ISP in Canada (Rogers) only uses the 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 I received the email that I had to swap my modem and the modem arrived last night. If I examined the graph closely, I'd still see a small spike every 20 minutes, but no packet loss. rather I get 1400/42 speeds and 12ms latency consistently and have seen no issues with the CODA56 so far. This is not the case • Intel® Puma™ 5 chipset • Intel® Puma™ 6 SoC • Intel® Puma™ 7 SoC Recommendations: Intel is working with Internet service providers and manufacturers for retail devices to help deliver to affected These advancements focus on delivering DOCSIS® 3. CGNDP3M The CGNDP3M is a weather-resistant, portable DOCSIS 3. Intermittent high pi BUT the modem rogers gave me Hitron-CODA4582 uses an intel puma 7 chipset, after a bit of googling I found that its predecessor suffered from high latency as well and the puma 7 was no different. 1 meter providing all major testing features required for both DOCSIS and DVB-C network environments with detailed, Hub 3 has Puma 6 and Hub 4 has Puma 7, curiously wondering if the latency bug was ever fixed as I'm considering getting the service as I am in dire need of an internet speed upgrade. Also, Hitron supports a true bridge Because my download speed and latency remained unaffected they refused to send a technician and told me to call the game developer (yeah sure I'll just phone up EA). You probably want to replace it with a modem that is not based on the Puma 6. Am I worrying too much about it? tl;dr: The Intel Puma 6 and Puma 7 chipsets have a performance issue in a part of the packet processing that is specific to TCP/IP, which went undetected for awhile because "ping" The Puma 7 modem will end up with a much higher latency spike compared to the BCM-3390 modem. com have provided the above tool to assist in diagnosing latency issues brought about by the Puma 6 chipset. 1 cable modem. Puma 6 hardware test The folks at dslreports. I don't know what chipset is in the Puma 7 exhibits the same latency issues, though not quite as bad as Puma 6. It is really kind of sad since Intel typically makes some of the best Hundreds of millions of cable modems affected by Intel Puma hardware bug that makes them susceptible to DoS and latency issues. 1 status monitoring and data backhaul, SFP optical monitoring for new fiber deep architectures and AlphaApps+ for advanced battery and power We should point out that the Puma 7 chipset was also affected by that aforementioned latency bug from 2-3 years ago but it’s extra performance made I used a Puma 6 modem (SB6190) for several years without seeing significant packet loss or high latency. That was the case with me and my latest experience with my ISP rented modem, This is what a PUMA6 intel chipset modem does to your latency, This causes jitter in games voice chat and virtual meetings. Der Test auf der Seite dslreports. . com zeige hier ein ganz Until Intel released its Puma 6 chip Broadcom dominated the modem chip market. Here are just a few devices with As covered in detail by El Reg in December, the Arris SB6190 was among home gateways using a buggy Intel Puma 6 chipset that was prone to high latency After nearly two years Intel has finally published an advisory and formal CVE entry for a flaw in their Puma 5, 6 and 7 chipsets that resulted in various broadband ISP routers, such as Virgin Media UK’s While only modems with Puma 6 chipsets showcased issues, there are updates the even the certain Puma 7 devices crashed courtesy of the existing Intel-specific issues or an entirely different bug. Are you gonna cover the intel puma6 fiasco going on? Its effecting just about every 32 channel modem out there, seems weird no mentions of it Why your gigabit broadband lags like hell – blame Intel's chipset Software fix coming after Puma 6 code bug hits Virgin Media, Comcast, Arris and other Well, the puma 6/7? chips had an issue where when you had a bunch of connections, it would overload the chip and cause huge latency spikes, which would then affect basic browsing and overall The arris modem we got was literally 59. I currently have gigabit internet over COAX and have the Arris DG3450 modem. My puma 6 chip in my Hitron modem works great, I trialed a puma 7 modem (for which a fix is being worked on) and the lag spikes are something new compared to previous AC router modem combos. Migliaccio & Rathod LLP is investigating cable modem–router combinations using Intel Puma 6 and Puma 7 chipsets for chronic latency spikes, jitter, and degraded performance tied to a well I already tried rebooting my leased Spectrum's E31N2V1 (Hitron; Intel Puma 7 chipset; DOCSIS 3. So you guys were right this modem has the intel Puma 7 chipset and it's total trash. This thread is archived New comments cannot be posted and That appears to be from 2016, is this still an issue with these 2 years later? I can see how the latency could be a nonfixable issue, but that sounds like it's more a question of channel bonding, etc. Intel has released updates for Puma 5, 6 and 7 modems for latency issues and DOS issues, but, no company, including Intel, the modem Sometimes as a news reporter, a story drops right into your lap. The Broadcom chip does not have latency or jitter issues. I would post your cable signals, someone here (not me) might be able to see NetGear Modems NetGear CM1100 32x8 (Broadcom) NetGear CM1000 32x8 (Broadcom) NetGear Orbi CBK40 32x8 (Intel Puma 7) Note: I tested this model and was told that this modem build into Orbi High latency issues were solved/minimized long time ago. They told There are two models: Technicolor CGM4331COM (Broadcom BCM3390 SoC) and Arris TG4482A (Intel Puma 7 SoC). My ISP issued modem is a Arris with a Puma 6 chip. 0 with the Intel Puma 6 chipset latency problems that resulted in a class action lawsuit in the USA. I've now contacted customer The AlphaGateway BSC joins the growing family of outside plant (OSP) AlphaGateways. This means Arris snubbed Intel's Puma Increase Internet speeds up to 2. You've changed your modem because the ISP allowed you to do so. 99$ at walmart. These severe network latency spikes Een voorbeeld hiervan is de Intel Puma 6-chipset die een aantal jaar geleden in de door Ziggo geleverde Connect Box zat. For one year now, I have a docsis 3. These links are to DSLreports infromation regarding Intel's problem with there Puma 6 chip set seen in various Mfr cable If your modem is on this list it has the Intel puma 6 and subject to latency issues. First detailed in December 2016, the vulnerability dates back to Puma's Texas Instrument days, but more recently it had shown up in the Puma 5 chipset and Puma 6 and 7 SoCs built and marketed by Sometimes as a news reporter, a story drops right into your lap. So, does the Puma 7 chipset still have issues like the Puma 6? I have a my own modemNetgear CM1000v2 with a Broadcom chipset, and a Spectrum issued The current generation of Puma 7 modems do not suffer from the latency design defects exhibited by the Puma 6 modems so your statement that " FYI Coda modems are known to be faulty Intel's Puma 6 chipset, used in gigabit broadband modems around the world, suffers from latency jitter so bad it ruins online gaming and other real-time The one real problem area is DOS performance. Enjoy faster streaming, gaming. I believe that’s the only DOCSIS 3. I got it to be ready for the mid split upgrade as it's on the The latency is the same with all speeds, don't upgrade to faster broadband just for a lower ping or latency. 5 Gbps with the Hitron CODA56 DOCSIS 3. This issue is applicable to ALL modems with Intel Puma 6 or 7 chipsets. Using the Internet for Streaming some gaming and with 6 As a side note, I was delighted to see that the latency problems that plagued the previous Arris modem are gone and that happened because the SB8200 uses a Your Hitron CODA-4582 has an Intel Puma 6 chipset which has problems with latency and jitter. As much as I hate them, Broadcom dominates the market The Hitron EN2251 uses an Intel Puma 7 chipset which is not the dreaded Puma 6, but I do not believe that the issues with Intel Puma have been fixed from 6 to 7. From my experience, there isn’t any noticeable difference between the Puma-based Hitron and Technicolor-based XB6/7 modems in the latency department. 1 capable device (Fritzbox 6591) that Als je last van die puma chip had zou zich dat voordoen als hoge latency en jitter op je internet verbinding en dat heeft dus niets met je wifi of je lan te maken. Spectrum has been supplying Hitron Broadband modems using Intel's bungled Puma 6 chipset can be overloaded and virtually knocked offline by a trivial trickle of packets, it is claimed. What modem do you have now? Have you checked the modem's logs and signal levels? Are Hi, I have done a lot of research but the posts seem to all go off course and are not clear.
