Hi i'm hoping some of the technical minded folks here can maybe figure out what has happened and the reasons behind it.
Ok this is a bit of a long story so I apologise in advanced but i thought it would help to give as much info as possible seeing as i'm on a ECI cab with A ECI modem and no means to post stats that would be beneficial.
Ok I joined plusnet back in March of 2014 with a IP profile of 65Mb down and 10Mb up my estimate then was 67Mb down and 11Mb up so i was glad to see i was not far off the estimate, three months later i get a drop to 50Mb down and 10Mb up Plusnet sent an engineer because a battery fault was detected in their tests yet the engineer couldn't find any fault with the line or the cab etc or the battery fault that Plusnet said there was and because i was still above my estimate range nothing further was done i was told by Plusnet that cross talk was most likely to blame and it was left at that.
upon checking the estimate range when i got the drop i see that it had been altered it no longer was it 67Mb down 11Mb up it was 38Mb down 8Mb up quite a change
Anyway it remained that way until around October 2014 when i got another drop this time it was the upstream from 10Mb to 5Mb, because the drop put my upload below the estimate a engineer was sent he ran some tests found nothing wrong with the line that he could see did a line reset ran tests again upload stayed at 5Mb so he put me on a different pair to the cab ran tests and again upload remained at 5Mb but I did gain 5Mb back on the download so was up to 55Mb which was nice, anyway the engineer couldn't get the upload back up to 10Mb and didn't know why it had gone in the first place and pretty much said that was all i was going to get now i asked if it was crosstalk he said no, i'm not sure if he said that because he didn't really know or that was really the truth.
So since then the IP profile has remained at 55.9Mb down 5Mb up until this morning when I awoke to find that it had dropped to 48.15Mb down but what surprised me more was the upload had gone up to 8.48Mb
I did a modem reset to see if i could gain anything back on the download but only managed a tiny increase to 49.04Mb down 8.58Mb up
I asked plusnet to see if anything was amiss they said nothing was i asked for my line profile to see if Interleaving or banding had been applied but it came back fine no restrictions at all.
0.128M-80M Downstream, Error Protection Off - 0.128M-20M Upstream, Error Protection Off
So the questions are what has caused the speed loss this morning and how the hell has the upload magically increased almost a year later when the engineer wasn't able to get anything back himself, it seems like a roll reversal of some kind, is it cross talk related or something else, as i say being on ECI doesn't help as Stats would be really nice but i thought maybe some one had seen something like this before and had an idea, basically am i stuck with the further download loss, the upload gain is nice but download speed is more important to me
