First off make sure there are no automatic disconnection settings turned on. eg in outlook etc
However I am on tiscali and had a similar problem and I found that since I have let windows connect to my broadband provider I have had less d/c.
To do this create a new connection under network connections in your control panel and add you user name and password and the broadband number and try connecting that way. I have in my expereince found it a lot more stable and quicker to connect than using the speedtouch software.
