Re: BT infinity really slow speeds because high usage.
I've been told that its is either over capacity or a fault at the exchange. My BT Infinity falls downloads to 4 Mbps for a whole day and evening and sometime shuts down completely. This is not functional use. It is not even stable.
If I complain by phone or EMail it can be briefly corrected but then the automatic computer overides it and the speeds goes slow again. I am a small business user and I cannot operate at these speeds. A loss at what to do.
