As the title states I have a very interesting issue, I decided to upgrade to 8.1 .. Big mistake there, now going back to 7 after I've installed the AMD driver suite (chip set, GPU, audio, HDMI) my wifi speeds drop from 30 to anywhere between .5 to 4mbps. If and only if I uninstall every AMD driver and run driver sweeper, my speeds come back. I've used latest drivers and beta, Im using A10 6800k APU and a roswill adapter.
