I tired all different setting for the QoS and it all worked like crap .. if it was on I got high Pings and loads of lag ON ALL Devices.
As far as the device manager - I am BLOCKING things and they are STILL accessing the router to the internet. I mean hell what else is going on and I cant even see it. Yesterday I had 4 unknown devices listed OFFLINE. I had ALL my devices accounted for so I blocked them and deleted them. Are they accessing my router?
I had NetGear back in the day and it was bad then, I guess nothing changed.
