this occurs because internet connection sharing was enabled when bluetooth was installed (this is a microsoft windows behavior and is considered proper operation).

    to resolve the “problem”:

    1. disable sharing for the ethernet adapter:

    a) windows control panel ] network and dial-up connections

    b) right-click “local area connection,” select properties, and then select the sharing tab.

    c) clear (uncheck) the box for “enable internet connection sharing for this connection” and click ok.

    2. re-enable sharing for the ethernet adapter; repeat step 1.c.), and select (check) the sharing box.

    if offered an option to select an adapter, select “bluetooth network adapter.” (this option will not appear unless more than one adapter is available.) if asked to reboot the computer, do so.
