After idling for a half hour or so, the game logs me off...

I try to set up a shop and go to sleep, or go do something around the house, but i found out that the game logs me off after a half hour or so. Is there any way I can fix this or what?

Check your modem, and your connection settings.

Control panel /-> Network connections /-> Right click on your internet connection /-> Configure /-> Power Management

Uncheck "Allow the computer to turn off this device to save power"
