So basically i've noticed in just the past few weeks that my wifi speed has decreased significantly, it used to be able to do speeds up to 50-70 mbps i believe and now it can barely do 3 mbps. I know it's not my provider as my wired connection easily pulls speeds up to 90 mbps, i've tried restarting my modem and adjusting the position of it but with no luck whatsoever. If anyone can shed some light on this problem, it would be greatly appreciated
