Yeah your very helpful aren't you it wasn't messing with cable lengths it was a change of cable and was changed twice one change to the 10 meter and then back to the shorter cable why should that cause dlm to make these changes it shouldn't do its not like I was constantly doing it I've asked for a dlm reset to someone from plusnet so it's up to them if they can get it done as there's always been a problem with this line if u look back thew my posts not just the cable length one that u just pick on
I chose the cable thread because it was the reason for your loss of speed none of your other threads pointed to the reason in this case
Why would it cause DLM to do what it did because changing the cable causes the modem to loose sync with the fibre cab DLM sees this and monitors the line, Had you did the change and left it alone for a day or so DLM would have been ok with that but my guess is you didn't you looked at the stats saw there was no difference then changed it back again in a space of a few minutes am i right ?
If so changing it back again caused another loss of Sync with the fibre cab, DLM doesn't know what your doing it only sees the drops so it intervenes thinking there is a stability issue with the line so drops the speed down, less speed equals more stability.
Your line is not capped / banded the GEA test Matt posted shows a 0.128M-80M Downstream profile that's the max if it were banded ie capped it would say something like 0.128M-75, the speed has simply been reduced leave the modem, cables everything else alone and the speed will return how long is up to DLM to choose there is no reason for a DLM reset in this case.
