I have a My Cloud Home, which I exclusively use as a base for my Plex server. Whenever the MC is connected to my router (Asus AC66U_BC) it causes total network congestion within minutes, even though my Router does not report the MC having any traffic. My WiFi speeds plummet from 90+/90+ Mbit to around 2/2 Mbit and most of my devices cannot access the network/internet, at all.
When I unplug the MC, speeds are returned within 3 seconds.
I have tried resetting the Router, enabling QoS and none of it helped.
When the MC is plugged in, there’s no problems streaming things to my TV, which is also wired into the router.
Any suggestions/solutions would be very welcome.
