When I install the KB4577671 update package, by 5Ghz wifi speed decreases dramatically. Usually its around 400 Mbps, after the update it is only allowing around 30-40 Mbps. The bad thing is I cant uninstall the update package. I had to wipe my computer and reinstall windows 10 and "hide" the update. Is there anyone who knows why this would slow my wifi speeds so dramatically?
