Windows 10: Miracast doesn't allow me to use WiFi

Recently I bought a TCL 49s405 TV. I would like to take advantage of the possibility to use it as a second monitor (I know there will be lag, it will just be to watch certain images, charts...). In the beginning, I couldn't cast anything to my TV at all; but after updating the drivers, I found myself at a weird spot. I indeed can connect to my TV, however, while I do that, my WiFi is useless. If I try to reload any webpage (it doesn't matter if I have it on my Laptop screen or on my TV screen) the connection drops, and Miracast disconnects.


My laptop is an ASUS X550VX running Windows 10 Home 1803 (OS Build: 17134.407).
