Hi, I just built a new pc and I am having trouble with the download speed on it. I am using ethernet and get around 18mbps download speed and around 20mbps upload. However on all my other devices which are all wireless I average around 70mbps download and 20mbps upload. So the upload is the same. I have all the latest drivers, stopped auto updating and sharing etc but still no solution? If anyone had any ideas I would appreciate hearing them :) (WIN10 x64)
