|Remove the saved wireless connection from your laptop then set up a new connection again as though you were doing it for the first time.|
how to remove: Control Panel >> Network & Sharing Centre
Click "Manage wireless networks" in the left panel.
Highlight the one you are having trouble with.
Click the "Remove" button in the tools ribbon.
Now set up a new wireless connection.
If you still have problems, unplug the wireless router, wait 10 seconds, plug it back in and wait until it has synchronised with your broadband line and all it's lights are showing no errors.
