Does the 770 go idle after a certain period of time? I was connected to my lan, and running xchat for irc chatting. I went to run some errands, and left it plugged in and running xchat. I came back and my lan connection was gone, and there is no way that it lost signal because of the fact my wrouter is so close. Does the n770 go idle and shutdown lan after time? This happens fairly often also.
