100M : Very High Latency (Hayes)

.. and then they claim that the majority of their customers are satisfied. Which then leads them to say that the wretched SuperHub is fine for all those happy customers stuck using wireless in one room!

Exactly that.

1-2% packet loss will cause the above behaviour. 50% will make the connection literally unusable.

I'm pretty sure people with a completely unusable internet connection would notice they have a problem.

As I have said, I have seen people with severe packet loss, only half of web pages actually loading and yet they still think their pc is at fault. We can be pedantic over percentages but I still wouldn't take a neighbours answer as completely reliable unless it was confirming they have also had issues.

Half or none? When nothing loads, ever, for weeks, that's slightly different from people thinking it's slow or flakey. The average joe cares more about the reliability of their internet connection than anything else, "as long as it works". They'd notice if it doesn't.

Qtx is trying to tell you even tho they may have to be retrying to get images to load they still think the internet is working.

One problem is that the ISP's are not responsible for the total end to end connection (or not usually) so the problem could be outside the ISP control.

And if there is an area fault that will need to be cleared before a more local issue can be sorted. (Or in many cases anyway.) It is annoying when you have an issue and get told it's an area fault so you need to wait until that's resolved. On the other hand an area fault is likely to be a higher priority than an individual user, it's just individual users don't see the results as clearly.

Engineer visited today again. Unfortunately I wasn't there since the wife went into labour so busy at the hospital.

There was someone around to let him in though and I gave him access to the PC so he could access the superhub admin page and see the power levels.

Just got home and the in-laws passed on the message "There was nothing wrong with the line"

Sigh. I've poked someone on the VM forums again. How on earth could he say there was nothing wrong and then do nothing and leave.

And what I'm trying to say is nomatter what they try nothing will work. And they will not think it is working when nothing works.

There's a difference between retrying a few times to load images and nothing ever loading nomatter how many times you try.

useless. you should have left a note asking to be moved at the cabinet to lower your upstream then for downstream to be adjusted accordingly.

Lol :P figured I'd be home. Didn't expect the labour to last over 24 hours... just got home to take a break and then I am back off to the hospital again :P

[thenry]

oh sorry mate i didnt read that bit. congrats

[Sephiroth]

Yeah - mucho congrats.

With regard to TH's point about being moved to a higher attenuation tap point.

The thing that's wrong is that your SH is maxing out on the upstream because there's a struggle to reach the CMTS. The internet may well work, but upstream will potentially be sluggish (loading web pages).

The upstream should not be high when the downstream is high. The downstream does indeed need to be brought down and the VM tech will (usually) tell you this. A forward path attenuator (FPA) on your modem can achieve that. By moving you to a lower attenuation tap point the downstream FPA will need very high attenuation (c. 20 dB IMO). That might not fix the problem at all if the upstream impairment is such that the lower attenuation is insufficient to overcome that impairment.

So it is the upstream issue that needs to be identified because the downstream power can be attenuated at the modem.

or splitter

By a forward path adaptor.
