Hi
If you're using a Wireless connection, is the wireless signal strength strong enough?
Also, what version of MSN/Windows Live Messenger are you guys using, and what other third-party plugins/addons/patches are installed with your Messenger?
When you're signed out of Messenger, are you able to sign-in again immediately with no problem?
Sorry for alll of the questions, but these questions will help us help you
