D-Link Smart Mesh WiFi Router AC2600

I am using it for security suveillance cameras and NVR plus wifi mesh with another repeater TP-link, Google chromecast to tvset; by its powerful processing power connects nearly instantaneus a wifi appliance for example android phone. My PPPoE connection has no disconnections at all none whatsoever, altough my old router was disconecting me from the broadband because the wifi webcam administring phone was umpleasant for the windows 10 firewall of the PC forcying me to use the phone on the 5G/LTE internet at home in the wifi range domain only to keep the surveillance camera connected by wifi on the internet in order to run it well which was very annoying - but with this router no problem. Another plus is how all the equipment is functioning off the bat at the moment of finishing the phisicaly wiring of all devices in a cabinet, at the elecrical power switch powering on : instantly the net is everywhere no overridings at all at the booting up in function including wifi + UTP local network, everything that is been phisicaly powered off from the grid one hour before, cables removed from their sockets for the rewiring through the cabinet holes. Deficits I didn't met no one ever.
