Also. This just in.... Issues are confirmed to be present on Intel Puma 5, Puma 6 and Puma 7 based modems. This story ran today. There is no fix at this time. This is Intel confirmed. http://www.theregister.co.uk/2017/08/09/intel_puma_modem_woes/ Note my list is used in the story as the reference list of modems for this issue. So to be VERY clear here. The firmware fix you got DID NOT fix the spikes. To be clear no one in the world using this modem has fixed spikes.

Your very welcome. I will send you my email in PM if you want to discuss any subject

I respect your decision. But from a testing standpoint, the SB8200 *might* be one of the best gaming modems ever made. I stress *might*..

Intel Puma based devices are currently crap. They *might* be fixable. However thats looking pretty doubtful. Would I personally EVER use them for gaming - hellz no.. I do, respectfully, disagree with some of the modems listed on this site as bad however. But. I defer to someone who has direct testing experience with the device being used, the Netduma. So I am staying neutral. This is a list of known good modems, tested and supported with the Netduma. Im great with that approach. However I think the list could well expand to include Arris devices Like the SB8200. The SB8200 has the lowest latency ive ever tested and the lowest jitter. However, I suppose there might be some weirdness with the Netduma and the modem. However I use Mikrotik CCR1036 so I use RouterOS and it works awesome with the SB8200.

Or maybe you prefer to look at a mode modern modem test... Here is a SB8200. TCP. at 0.1 for 12 hours... Not a spike in sight.

LOL... Wow.. Your not the brightest bulb in the shed.. You know right im guy who forced Intel to admit there are still issues right, developing tests with pingplotter no one had done before ? You know im the guy quoted in press on this issue right https://www.theregister.co.uk/2016/12/03/intel_puma_chipset_firmware_fix/Im the guy in the class action lawsuit who did the tests, you know that right ? http://badmodems.com/Files/arriscomplaint.pdf You know Intel has OFFICIALLY acknowledged there is still a issue with Puma 5/6/7 right https://www.dslreports.com/forum/r31122204-SB6190-Puma6-TCP-UDP-Network-Latency-Issue-Discussion~start=5788 Im not sure you could find anyone on the internet more versed on this issue besides me. WELL,, Its been a team effort of course with a core set of people on DSLR. And NOOOO to answer your question, ONLY Intel modems have issues with .3.. I do all my testing at 0.05. 100 pings a second is a good temporal resolution. I have chart after chart showing modems going back 15 years that do this just fine.. Here im doing a direct A/B with a 14 YEAR OLD DOCSIS 2 modem at 0.1 THREE TIMES FASTER THEN .3. I swap modems in the middle of the graph.

The fix you got WAS significant however. It fixed DNS lookups. Your old version of firmware lost 7-15% of ALL dns look ups. This was terrible. Thats fixed now. What this update did tho was HIDE the spikes so you cant see them with ICMP Ping and common tools based on ping. You need a Broadcom based modem.

To set up pingplotter properly I have a page for that. http://badmodems.com/Tools.htm And a specific page for pingplotter setup http://badmodems.com/PinrplotterInstructions.htm

I would call it cosmetic. I would know. You have your Pingplotter set for ICMP.. This is a mistake.. It needs to be set for TCP. AIm it at google.com and set the interval for 0.05... And the spike will be very clear indeed.. You see... There is no Intel Puma, 5,6 or 7 that has been fixed in any country in the world on any ISP.. The press looks to me for updates on this matter. So I can be considered a verifiable reference. For gaming, EVERY MODEM ON THIS LIST SHOULD BE CONSIDERED CRAP UNTIL FURTHER NOTICE. http://badmodems.com/Forum/app.php/badmodems I have a web site and it has a "is it fixed" link I will update once a version of firmware is available that might, or might not, fix the issue. http://badmodems.com/ This video shows the most recent firmware and has TCP and ICMP pingplotters running at the same time.

awwww... I was hoping to get NetDuma in a multicore router Im not sure you really need firmware to do the things it can do. So that also means they are locked into that hardware. Awwww... You know. That has to change actually. Multigig is here. That hardware wont do it. Hmm.. I see OpenWRT supports that Mikrotik product.. https://wiki.openwrt.org/toh/hwdata/mikrotik/mikrotik_rb951g-2hndBut OpenWRT is not supported on any of the modern Mikrotik platforms that are multicore. Well... and this is important.. Gaming is really not about bandwidth, its all about latency. So a gamer really should not need speed. So the NetDuma should be fine as long as you dont do other things while gaming. The Ubiquity might be a good platform as its opensource and is OK powerful. But change needs to occur in the NetDuma, its a multigig world now and you need at least 1M pps. maybe 10M.

Its *possible* to develop firmware, but more likely its a good set of configuration settings. RouterOS is very configurable and could do everything listed by NetDuma with just clever config. That DOES NOT TAKE AWAY FROM ITS USEFULNESS. and a good router setup is tricky so no doubt hard to develop. If its a RouterOS config tho, it could literally be just loaded into ANY Mikrotik router. Thats REALLY powerful as you could apply the same Netduma skillz to a 72 core $3000 router. Cox in my area plans 2 Gbps by the end of 2018. 1Gbps in the next few months.

The router the Netduma is based on is single core and pretty dated now. Its for sure not capable of gigabit speeds and with 64byte packets can only do 32Mbps. https://mikrotik.com/product/RB951G-2HnD I would think that you guys could do whatever settings your doing to any mikrotik router and off better performance devices ? I would be interested if you could stuff your tweaks into a cloud core router. ANY router now for consumer use needs to do 2Gbps with NAT and Firewall as a design requirement, even with all your tweaks turned on with small packets ( DNS ). This means SFP+ on the LAN side and/or port aggregation on the WAN/LAN sides. Multigig is here. Its time to step up to the plate with a router for that use.

I assume that since the NetDuma is based on Mikrotik, that maybe, whatever settings or firmware used in the Mikrotik being rebranded by Netduma could also be used on the more powerful routers ? Im also a bit confuzed. Whats the difference between the Mikrotik and the Netduma rebranding ?

This a interesting list... Im not sure I follow all the reasoning. Im fairly deep on this subject. Your aware right that inside these various modems the modem mfgr literally uses the same components exactly so each modem makers easily passes DOCSIS certification ? Each chip, like the Broadcom 3390, has virtually the same parts no matter who makes the modem ? The changes in firmware modem maker to modem maker never ever involves changes to the chip drivers so they all perform the same way. I know this because ive done A LOT of performance testing. In general, for gaming, almost any Broadcom based device is going to perform exactly the same no matter whos name is on the box because the electronics inside are the same. As you have rightly called out. The Intel chip is where the trouble lies. Also the TI Puma 5 before it is also a slight issue. So the Puma 5/6/7 should be completely discarded and avoided for gaming. Broadcom in all models will work pretty much exactly the same. Whats FAR more of a issue for gamers is wifi. Wifi is horrendous for gaming. Its far more important to PLUG IN A WIRE then worry about what broadcom modem your on. In general for latency, more channels is better. So a gamer wants a DOCSIS 3.1 modem like the CM1000 or SB8200 etc.. Also consumer routers all pretty much suck, so getting a Mikrotik or Ubuqiti is a good move. However these routers require config and skillz to master them. Every network should consist of 4 things. 1 Modem 2. Router 3 PoE Switch 4 Access Point powered by PoE switch A router today should be able to use port aggragation ( more then one WAN port tied together ) so you can reach speeds beyond 1Gbps. The router should also be capable of sustaining 1Gbps thru NAT and Firewall even with small packets. A million packets per second is a reasonable minimum target. No consumer routers can do that performance. You need a multicore CPU in a router to do that. The wifi point should be a low latency 802.11AC wave 2 device. The best way to do all this the best way on earth currently is IMHO: SB8200 or any Broadcom 3390 based modem with 2 ports https://mikrotik.com/product/CCR1072-1G-8Splus stuffed with 2 SFP modules for gigabit ethernet in port aggregation for the modems dule ports a SFP+ Direct Connect cable to a SFP+ Netgear switch http://www.netgear.com/business/products/switches/managed/m4200.aspx a access point from Aruba http://www.arubanetworks.com/products/networking/802-11ac/ Also think 10Gbps. Not for the speed, but for the lowered latency. The above is like $7K. I install these setups in homes. I have gamer clients. I know what im talking about. You can get a budget version for like $1K or even maybe $500. My point is that focusing on the modem as the only weak point is missing a lot of other issues. Mikrotik makes great REALLY affordable routers. Get one. Ubiquiti makes affordable access points that are low latency. BUT PLUG IN A WIRE IF YOU GAME.. Multigig is about to become a reality this year in a lot of major cities. So this requires a much higher level of network performance that no consumer router can currently do. For gaming, a broadcom modem like even a SB6183 + a basic Mikrotik router https://mikrotik.com/product/RB2011UiAS-2HnD-INand a plugged in computer will provide killer low latency. This wont do real life speeds over 300-400mbps, but, will provide great latency and a solid 300-400 Mbps all the time.
