Sounds like your Bluetooth on the laptop is erm, playing up. If you can do without it or want to, then have a look in the add/remove software tab in the control panel to get rid for good. Alternatively, a quick delve into network connections (Control Panel again) will let you right click on a network connection and reconfigure it or turn it off.
The only catch with this, is that it removes some of the functionality from your Laptop. Do you really want to do remove the software?
