I'll try to give you a brief rundown of everything they've done (with graphs for reference):
We didn't have an internet connection for 10 days, there was a fault in my area but it shouldn't have kicked me off completely, no one could tell me what was wrong though or when i'd be back online which is why I emailed 3 directors in the hope that it would get sorted.
They sent an engineer out, he said there was no problems with my house sending a 'signal' to the cab across the road (its opposite my house)
it was the return path that had the issue. He upped my power levels really high and put an attenuator (spelling??) on my box which brought the power levels down inside the house. This worked and we were back online, but had mega issues with speed, not being able to load web pages etc.
[SEPH]: I think I've hinted in other replies that the upstream is a suspect candidate here.
This is my connection straight after they got us back online, not a problem in sight really:
Everything was ok until the middle of October, when my graphs started to look like this. Terrible internet again, slow speeds, loads of lag on fifa, web pages not loading etc:
[SEPH]: Again, games lag and slow web page loading is an upstream issue.
Another engineer came out, said he couldn't see anything that was wrong but swapped the superhub over.
The internet was fine for a day:
[SEPH]: I can't account for the regularity with which the system was fine for a day!.
Then it stayed like this for a couple of weeks, really terrible internet connection, slow speeds, loads of lag on FIFA again.
A principal technician (awesome chap!) came out and said that our power levels were stupidly high, he dropped these and took off the attenuator that the original engineer fitted. He spent a lot of time at the cab and called another engineer to come out. I didn't fully understand what he said, but he said that he believes theres an issue at the cab and has escalated this. He's on holiday until the 3rd December though so I can't get him to come out again and take another look...
[SEPH]: When you do get his attention again, it's the upstream he needs to look at. Your power levels are ideal at 0 dBmv DS and 40 dBmv upstream. They are also ideal if the downstream rises by the amount that the upstream falls and vice versa, provided you don't go below -4 dBmv on the DS. If they're so out of balance that he has to put you on a low attenuation tap at the cabinet just to get the upstream going but then your downstream power has to be attenuated, then there's likely to be a faulty amplifier in the cabinet across the road. But then other users in your street would have similar issues.
After he left the connection was fine, you can see 6pm when he left.
Then a few days later it was all over the place again, then we had really bad packet loss every day and
only had one downstream channel, which they managed to sort from their end, they said the superhub had been configured incorrectly from their end. They still sent out an engineer who confirmed everything was fine.
[SEPH]: One downstream channel is a fault in the infrastructure somewhere. Often in the optical node a few streets away from you. In fact the whole problem could emanate from there.
it IS working fine in terms of speed and pingtests (although we can't test FIFA till payday as my other halfs gold account on the xbox has expired
), but I firmly believe from my think broadband graph that there's an underlying issue here that's causing these bizarre graphs.
[SEPH]: I do recommend JDAST speed test as it runs from your computer and has excellent graphics. You can watch the latency test graphically and it would be a useful check against the TBB graph.

So as you can see... no problems, just a really odd graph!
