* When you say you are logged out, do you mean you are logged out of Windows or that your internet connection is terminated? (Or both?)
* What can you tell us about your hardware? The make/model of both the modem and NIC may be helpful, as it's possible this is a compatibility issue with Vista. If it is, you may be able to solve it with updated software and drivers.
Let us know.

Just started using Vista with ny broadband connection via Ethernet cable. Can anyone help with when i am connected to the internet all is working fine, until i leave the set alone for a period of approx 30 / 45 mins without any inactivity the system has logged me out
And the only way to reconnect is to either re-start or remove the cable and re-instert it again?
My laptop with a similar cable to the same modem has no problems (XP)
