Engineer was arranged for the 28th December, who came and did some tests. No fault found with the line, it passed their test suite. The engineer noted the high error count. During his visit he checked the cabinet, distribution point and house socket.
Provider Bandwidth --> Cabinet --> Distribution Point --> House Socket
> No errors at the cabinet
> Lots of errors at the distribution point
> Lots of errors at the house socket (downstream of DP)
He 'changed pair cables' between the cabinet and distribution point to attempt to address the errors at the distribution point. This reduced them somewhat, but lowered the sync connection of both upload and download in the process. However, the underlying problem with slow speed still remains and the engineer didn't have an answer for this.
Usually receive 5-10Mbs during peak times 6pm-11pm. However, have been receiving speeds of approx 25Mbs around xmas period (incl before the engineers visit, engineers visit doesn't appear to have changed anything). Contention on the network is probably lower than normal given it's xmas and people with be on holiday/away so difficult to tell if speeds have permanently improved during peak times, or if it's just temporary.
Even still, speeds of approx 25Mbs is less than half what I'm syncing at. Given the line has come back alright following the engineers visit, the logical conclusion is Vodafone have not bought enough ISP Backhaul at my exchange and speeds they can provide are suffering.
