Hi I was having issues with large fibre speeds last year, which were fluctuating wildly, but they have now stabilized by themselves.
However, my speeds are now down to around 51 Mps where previously they were rock solid at 65Mps for around a year. Since the official talktalk speedchecker hasn't worked since the security breach last year, I am using the speedchecker I was previously asked to use by a Talktalk rep (http://www.supportal-test.co.uk/).
Could somebody please look into this for me?
