Hi,
Locate the Network Adapters section in the Windows Control Panel, select and right-click "Local Area Connection" there, select Disable.
Give it a few seconds and Enable it back again. This usually does the trick.
If not:
In the Control Panel, open Internet Options, click on the Connections tab, select "Never dial a connection", click on the LAN Settings button, check the Automatically detect option, OK, Apply, OK.
