I've been having really inconsistant packet latency for the last 3 months or so that seems to be getting worse. I'm on M600 with the SH3 in modem mode. I'll disclose from the start that I'm a Cisco Engineer in my line of work, and probably have an above average network setup at home. I have an enterprise grade firewall connected to a Cisco Catalyst switch, and most of my equipment including the gaming PC is hard wired. Whats happening is that my ping is nice and low, between 15/30ms depending on the server. Then out of nowhere, latency to the servers will go above 150, for a second or two and then go back to normal.
I've since installed an OpenWRT running SQM Cake to combat the obvious bufferbloat that my connection suffers with, sitting betwen my firewall and t]he Super Hub - This has brought my score on the waveform bufferbloat test (https://www.waveform.com/tools/bufferbloat) from a D down to an A/A+ depending on the time of day, but it still has this random blip every few minutes which results in either a missed shot in CS:GO or a pause and shift/jump in Rocket League. I've tried deploying QoS on my Layer 3 switch, QoS on the Firewall, disconnected all but a single PC for testing, including disabling my wireless access points, nothing seems to prevent it. I've even tried rate limiting the connection down to as low at 100mbps by manually configuring my port to be 100mbps full duplex, but nothing seems to prevent it, so I don't believe its anthing to do with a congested connection from my side.
Is this likely the rumoured bug with the Intel Puma chipset in the Super Hub 3?
BT have just ran FTTP past my house, and i'm seriously considering switching to them when my contract expires, as this is getting beyond a joke now - you can see from many in this forum that a lot of us are having these problems and are getting fobbed off by VM. I've only stayed with VM for all these years as the competition couldnt come close to the speeds that VM could, but now that they can I'm going to need a lot of persuasion not to switch.
What do I need to do to get a SH5? and is this any better? or is it a case that my area is just oversubscribed and / or DOCSIS3 isn't suitable for these sort of speeds?
As I speak the issue is very bad today, so bad infact I'm only getting a B grade on the waveform bufferbloat test, with the odd latency during downloat in the 400's!!!!

I think this graph speaks for itself (apart from a brief drop in service yesterday afternoon for about 60 seconds that is)...
