I joined Plusnet in January. My estimated sync was c. 26 down so I was thrilled to see 33 down when the service started. This fell over the first week or so but settled at almost 30 down and 7.5 up so I remained happy. This was consistent (outside of some of the issues lots of Plusnet customers seem to have suffered with high pings and low speeds some evenings).
Then around 10 days ago my speed fell down to around 27 down but the up speed went up to 8.5, where they've both stayed since.
Is this usual ? I've avoided re-setting my router and modem because I'm unsure of the impact of re-starting the modem (unlike ADSL etc where it doesn't seem to cause any issues). Did anything change generally in late March that might have affected the speeds, or should I report the fall ? I'm aware that my speed is pretty much now where the original estimate was, but it held the higher speed for almost 3 months.
