So I am a customer using the BT infinity fibre optic package who is, according to www.speedtest.net, getting a 21ms ping time, around 40mbps down and around 18mbps up. However when trying to download file from the internet I keep recieving a predicted finish time of 6 hours. To put this into context these files were 200 - 300 MB big. This should've at the speed shown, have been completed within minuites of starting the download. Up to very recently I have been very pleased with the internet quality BT have provided but download times like these are unsatisfactory and disapointing. Please reply to me with a fix. I do also understand that my speeds will fluxtuate but should never get this low.
I am using a TP - LINK Dual Band PCIE wifi adapter.
