So yesterday I finally got around to upgrading to Windows 8 Pro, my college offers a download of it with our tuition costs. My problem is this, ever since upgrading my internet has been slow. Not just slow, like terrible. I live in the country so I get what I can and before the upgrade I was sitting at around 360KB/S. Now after the upgrade I sit at roughly 20KBP/S and 50. I have forced Windows to install updates using the update manager. I have updated my D-Link DWA-160 Xtreme N Dual Band adapter manually. I have reset my router and I have also installed the new driver for my Realtek PCIe Lan Card. I really do not know what to do? I want to say it is a driver but I am not sure what it could be as I have covered all of them?
