The BQM is truly appalling, but there's nothing obvious in that or the posted stats to explain what's causing it. So the BQM doesn't show a classic shape of over-subscription problems, the power levels are good, signal to noise ratio is good, upstream isn't showing obvious problems (although I have a suspicion that might be where the problem lies). Error levels look like the hub was restarted fairly recently and are rising rather fast, but given the packet loss showing on the BQM that's to be expected.
Usual check that the cable between internal wall box and the hub is properly connected with finger tight nuts, but that's unlikely to be the cause. You may want to measure speed (via an ethernet connected device) at different times of day, and also post you hub's network log here, but ultimately this is down to the forum staff either advising of a known area problem, or getting a technician booked.
I am having the same issue. A few times an hour my ping goes to over 300, packet lost goes up to about 40% and download speeds go from 385mb to less than 1mb. This lasts for upwards of 20 seconds at time.
I have reset the hub 3 to factory settings a few times. Everything is plugged in correctly and tight.
The maximum (yellow) latency hasn't looked that settled in ages - I've just gone back and checked (to the middle of December). And I can't even find a time where the average is that close to the minimum.
So it would appear that, for now, it's fixed. Let's hope it stays that way. Any one have any idea why it would be this bad for so long, then get fixed when I raise an issue on this forum? I'm presuming that someone @ VM has spotted this post and done something, but there has been no official communication.
Also, one other quick question - does anyone know if it's possible to export the raw data from the TBB BQM?
At a guess, the cause was an area problem or upgrade work that's now completed, and fingers crossed will stay that way. I don't think raising it on the forum will have provoked action since the forum staff would have told you about planned work or an area fault.
I have a suspicion from the number of similar complaints in the forum that VM are doing extensive upgrade work in relation to their plans for national gigabit roll out (well, almost national, they won't upgrade an area network if they don't think the financial returns are there), and those network changes are affecting people's connections. I had a dreadful two week period in January that caused weird BQM traces, and that resolved "of its own accord".
Even if I guess right, it doesn't follow that if we have a few weeks of disruption our areas are going to be offered gigabit connections - the disruption isn't necessarily on your local cable segment, and could be anywhere on VM's backhaul to the real internet.
