Hi I've noticed a reducition in download speed.
I thought this might of been a problem with main PC, but have just checked on second pc and that is the same.
I was getting around a solid 37.5Mbps download speed, this has reduced to to between 20 to 30 Mbps.
Both PC'S are connected by ethernet cable have tried turning firwall off and no improvement.
Router is reporting a download speed of 39.95 mbps and upload 9.999 mbps.
The reduced speed started on 27-9-17 and recently been having problems streaming video.
