I have tried it without AV, taking off any network software installed with lan drivers just incase and still seems to be the same, the fact in safe mode I hit 950+ means it has to be something driver related or software.
Just need to work out which, it has been 3 years I think since last install so its due a clean install
Thank for all the suggestions you have been very helpful
I it would seem it was a network card driver causing the slow down. I tried an older driver, gave better speed but more buffering on the connection, on newest dirver was the other was slower speed less buffering. As my network adaptors are built on, and my motherboard is old the drivers I could get where not that new.
I bought a cheap £10 TP-Link network card, and that is running find with 950 down when I know someone was watching Netflix. So I did not need a reinstall it was just bad drivers for my motherboards network adaptors.
I will run test again when no one else is using internet, but seems better
