How can I stop the "Broadband connected" balloon popping up when I turn on my computer?

Hiya,
Go to Start and click Control Panel. Double click Network Connections or click Network Connections and Internet Connections and then Network Connections depending on which view you use. Find your connection and right click it and click Properties. Remove the checkmark from the Show icon in notification area when connected option and click Ok.

Thank you Owen, I found that so annoying.

Problem solved.

Glad your sorted
