-These problems can be caused by lots of things, but one of them is that the WiFi adapter may be set to run in a low-power or power-saving mode. If it's not busy, then after a while it goes into a low-power mode. This is bad as the device needs to be always connected to the network to provide the AirPlay service. You need to turn off power-saving mode. How you do this varies with platform and with WiFi adapter – internet search is your friend. Here, for instance, is the command for the C.H.I.P. from Next Thing Co, which has built in WiFi and Linux and has the `iw` command installed:
