For some reason my PC, over the span of a week, drops from 500 Mbps Download speed and 35 Mbps Upload speed to 5 Mbps download and 5 Mbps upload. It is only my computer, and restarting the router has been the only thing I find to fix it. No one else in my house has any issues with the wifi at all except for me. Could this be something I downloaded and is a virus slowing my computer down, or is this some problem with connecting. My ping is normal, but the speeds are very slow. I am currently testing to see if switching off my wifi card and using a netgear thing will help, but we are thinking of just full wiping my computer at this point.
