For the last 3 weeks the broadband via our Homehub 3 has been dropping repeatedly but intermittently. Sometimes it will be stable for hours, other times it will dropping as sonn as it has come up again, so every couple of minutes. We have had two visits from engineers. The first replaced the ancient entry box (although we had never suffered from crackly lines) and then monitored the line from both inside the house and outside for about half an hour, but no fault manifested. The second replaced the brittle line coping into the house (and was horrified that the previous engineer hadn't, given that it had blue tape wrapped around a join just outside the window where it came into the house and was very brittle) back to the junction where the line into the house split between ourselves and our downstairs' neighbour. Having said that, even wiggling the brittle ljoin vigourously didn't trigger the broadband to go down. The engineer even commented on ouw low the error rate was - only 1.
The 2nd Engineer appeared to identify that the problem was exchange side as he managed to pick up the fault at the cabinet. He worked with the exchange and changed the SNR setting to 6dB which he thought/hoped would resolve the problem. It was stable that evening (last Friday) but since then the Boradband connection has been sropping if anything even more frequently.
I contacted the 2nd Level Help Line via the SMS message that had confirmed the Engineer's appointment (took them over 5 hours to get back to me and that was only after a follow-up SMS) and they seemed to say that I might had a more unstable service for a couple fo days and just to see out it would settle before ringing them back.
Having read the forum here, I am reulctant to ring them back given that over 3 weeks we are if anything worse off.
Here are some of my stats (there are another 2 pages!)
These stats are probably more useful. I resume "connection time" is since the last time the broadband disconnected.
