I was moving a file over the local network using wifi connection in explorer. The label said that approximately 10 minutes of time is remaining. I closed the lid and returned after ten minutes. Almost nothing was downloaded during that ten minutes and I saw the label saying that few hours of time is remaining. And during the time I had been watching it the speed was increasing. I repeated this experiment several times and watched the graphs visualizing network utilization in Windows task manager. I saw every time the same result. During the time I was watching the nerwork utilization was approximately 25% of 117Mbps and the graphs were showing that the network utilization druing the time the lid was closed is near to 0%.
What is happening? And why do I need to sit before the computer in order to make it work?
Note that the computer surely wasn't sleeping. I can listen to the music normally when the lid is closed.
