I have successfully hooked my DS3880W to my network yesterday. After airplaying for a bit i switched it off by pressing the power button on top. A few minutes later i tried to switch it on by tapping the power button but nothing happened.

After pressing power for varying lengths of time i finally got it to power up but i had to set the network up again.

i switched it off again last night but cant get it to power back on today.

possibly stupid questions, but how are you supposed to switch this thing off and on?
