Server-hosted games - machine going to sleep?

Yes unfortunately I have found that to be the case. You have to either daily or every few (2-3) days reset the router or the server computer due to some connectivity problems. I thought this was an issue with WinXP for me. I did however notice that Dom2 is fairly sensitive to bad packets and things of that nature. Maybe someone who knows more about such things than me could offer some help or advise.
