hi, as it says in the title i have a problem with my internet speed it used to be fine until about a week ago when it started to drop down after an hour or so of restarting the router/modem. on WIFI 5g tho i get the full speed, i tested it with a 1Gb device and a cat6a cable and it always drops after a while below a 100

Hi everyone, i was wondering if there is a way to make a smart tv into a monitor with no wires like through Wifi or casting, there is a way to cast media but what about the whole desktop and some programs with some input lag.
