i have 2 laptops... sometimes for 2 straight weeks, no disconnects... sometimes one laptop would disconnect once a week but the other doesn't (meaning, it's not the home internet, isp or chronos server), it's probably something in the OS... It's not just always one laptop, it's kind of random between the 2 laptops...
other than OS, chronos server may just random REJECT packets coming from a specific network MAC address...
