Laptop keeps disconnecting from internet

I have an Asus X550CC-XX424H with windows 10. Sometimes my laptop disconnects from internet (sometime fully, sometimes partly (yellow triangle at wifi symbol)). To get it working again I have to close my laptop and wait till it goes to sleep. Then when I open it, I'm connected again. It only works when I do this. When I turn wifi off and on, or try to reconnect to the network it doesn't reconnect. It happens on multiple networks and the time between disconnections varies between minutes to hours.

Does someone know how I can fix this?
