if thought superhub was bad design, BT even worse
I laughed hard when I read BT's home hub 3 only got 1 gigabit port, instead of all the ports.
How weird a design decision is that.

Probably using a butchered Thomson TG789vn or similar variant, which by default only come with 1 Gigabit network port.

Chrys
Not to mention the apparent inability of the Home Hub 2 to receive incoming pings. Can you get the Home Hub 3 to receive incoming oings like from thinkbroadband/ping?

Re: if thought superhub was bad design, BT even worse
I think BT disable the ICMP responder and don't give you an option for turning it back on 
The only way to do it would probably be to hack into the CLI but BT lock the modem down to stop you from doing that
Infact anything after firmware 6.2.2.6 on the original homehub had the CLI access locked out.

I've removed the HH2 and put in the VM sup[lied DIR-615 and, of course, thinkbroadband/ping works.

Re: if thought superhub was bad design, BT even worse
I can just about see from the latest image that packet loss actually hits quite high levels at some times of day - peaks between 5 and 10%. Not completely clear due to the small image size though, but it looks like there's some actual line problems going on.

Re: if thought superhub was bad design, BT even worse
If there were line problems, I'd expect the maximum ping to rise significantly. Trouble is the Boy isn't here playing Black Ops and using Ventrilo so I can't say whether or not there were real problems. The stuff I was doing behaved perfectly well - pages loading normally, downloads working well, speed tests fine..

Uncorrectable errors would result in a CRC error being detected and the packet being dumped.
Therefore they'd show up on the graph as packetloss

Re: if thought superhub was bad design, BT even worse
Yeah - but from 12:00 to 20:30 there was no use of the network from my side. Only the ICMP traffic from Thinkbroadband/ping.
So whilst what you say is true, this wouldn't have been the case here.

ICMP is still traffic passing over the line.
Line errors could be due to noise interference or slightly bad joint being aggravated by expansion/contraction or wind (if its an overhead line) doesn't have to be tied to your usage pattern.
Shame the modem is so locked down as I suspect it records the error rates.etc much like ADSL modems do.

Ive been seeing it on tons of graphs on tbb, but all the end users shrug it off as if its not an issue, seph's is light compared to others I have seen. FTTC seems to have common line quality issues or the isp's hosting it are having issues.

So BT are mark I of the isp's who treat customers as children, locking them out of toys lol. VM mark II with the superhub.

Hard to tell, VDSL2 is a lot more sensitive to interference than ADSL2+ but I don't have enough knowledge on VDSL or indeed BT's network to isolate the actual cause of the issue.
I'd really love to see the stats from a VDSL modem to see what kind of information you can get and if it reveals anything interesting.

Re: if thought superhub was bad design, BT even worse
We perhaps a step closer to know as to why BT locked out modem stats from viewing.

Wanna know for sure? Get yourself a VDSL modem, plug the line from the active NTE into it and see the stats for yourself. Only gotcha: any faults raised on the line need the line into Openreach's active NTE.
EDIT: Thomson's TG789 should do the job, if you can find one. If not, PM and I can possibly source one through work.

I don't have VDSL at the moment, FTTC is available in my area but i'm not going to sign up just yet as I don't want to tie myself into a 12 - 18month contract.
