I recently moved to BigPipe VDSL and as part of that had coffeebaron in to change my splitter from the ADSL one he installed a few years back, to a new VDSL one. As part of the move I also signed up for a VOIP service so I only have the VDSL modem on the line, and its a direct CAT5 run from the demarcation point.
When I moved to VDSL I was getting 10 up and 43 down, even before the new filter, and this persisted after the change in filters. This speed stayed constant for several weeks, however a few weeks ago I noticed the down sync speed had dropped to 31. I think this was after the modem went off (it was plugged into a socket and the PSU came loose). Since then I have restarted and powered down the unit, but no change.
Does anyone have any ideas as to what could cause this? Should I raise it as a fault to BigPipe, or is it more likely to be someone else on the cabinet with VDSL and no splitter? If so, is this the magnitude of change that can occur from no splitter on a line?
I am approx 200m from the cabinet, modem stats are:
