This has never been an issue for me before. But recently I am downloading paid movies on itunes/Youtube, and despite my settings to NEVER go into sleep mode/screen savers. But after 30 mins without touching the keyboard, or using the computer. The Screen Savers would kicked in, and disconnected the wi-fi. I had to go back in and re do the download all over again. Is there anyway to disable this so my screen savers would be disabled and my wi-fi connection stay on? Thanks.
