I got the problem with "sleeping network" again. This time I'm absolutely sure I wasn't doing anything that could provoke the sleep. The computer was with the lid closed, HDMI connected to the external monitor. I left for lunch. When I returned. the network was "sleeping", the crescent shaped LED on the lid was blinking.
